viewpoint THE SANDS OF TIME! Imagine, if you can, that instead of all that foul flood water we endured last month, the whole of the UK was covered in a very liberal sprinkling of sand. Boffins have worked out that would roughly equate to around 50 billion tonnes of the golden stuff or, in other words, the current total global consumption of sand in a typical year. Not a problem, you would think… after all, deserts make up one third of the planet’s land surface area and then, of course, there are the hundreds of thousands of miles of pristine coastline, with beaches stretching as far as the eye can see. Fresh water, clean air, polar ice caps, yes we get the concern about access to all that, but surely there will never come the day when we actually run out of our most prolific aggregate? “We can’t bury our heads in If all that sounds like an appropriately timed April Fools’ spoof story then we are sorry to be the sand any longer as the the harbinger of bad news, because it seems that construction industry faces the threat is all too real. In fact, the sands of time are quite literally running out for another natural the very real prospect of going victim of excessive human consumption. short of one its most vital, but The key here, of course, is to understand that largely taken for granted, not all sand is the same. Those industries – from silicon chips to concrete, glass and abrasives – building components.” which are reliant on it as a vital ingredient of the manufacturing process are much more discerning than you might have first realised. Concrete and glass production in particular needs sand to coalesce consistently and, as such, needs to be compressed to uniform grains. Desert sand is shaped predominantly by wind, making the grains jagged and sharp from chaotic patterns of erosion. Beach sand is more gradually eroded by the steady march of our oceans, producing semi spherical grains of sand that can be moulded much easier. Problem is, their location and, of course, unpredictable natural shifting, often makes them difficult to access on a viable industrial scale. And yet, in the midst of all this, the demand for sand is growing at an unprecedented level for a great number of reasons, but predominately because of global construction and urbanisation. We are simply growing faster than anyone could have predicted, and sand has become the undiscussed cornerstone on which our new mega cities have been built. In fact, entire landmasses are being artificially constructed to help China in particular lay claim to new bits of valuable ocean. In fact, the plundering of their iconic rivers like the Yangtze and the Yellow for sand is already having serious environmental issues on the surrounding habitats. The worry is not just that sand is finite, but that the sand is now being extracted faster than it can naturally be replenished. Worrying times then for the big construction boys, but what does it all mean to you, the average small developer and jobbing builder? Well, you may have already noticed from your supplier that the price of sand and gravel has increased dramatically in the past decade, and will almost certainly continue to outstrip natural inflation rates as demand soars. Given our still traditional way of building, the UK construction industry, in particular, will be especially exposed to these hikes as every new home requires as much as 200 tonnes of sand in its various applications, bricks, mortar, glass etc. There are some alternatives out there, but at present these are prohibitively expensive. Aggregate compounds formed of limestone, copper slag or siliceous stone have long been posted as potential replacements for the construction industry’s ravenous demands for sand, but the simple fact is there is just not enough of it to go round. In fact, there is no material on earth that possesses the qualities of beach sand, and one that also exists in the abundance it is needed. The grains are undeniably slipping through the global hour glass at an alarming rate, but thankfully, it seems, our time has not run out completely just yet. Two researchers – in the UK of all places – have pioneered a way to use desert sand as a filler in concrete. Their company, Finite is selling a new concrete type binder as an eco-friendly alternative to concrete that would not only use plentiful desert sand but also processes less than half of the current carbon footprint of traditional concrete. Professional Builder readers who are reading about this crisis for the first time, and worrying about future margins, should keep an eye on the news coming out of Africa and the Persian Gulf because it is clearly not just our vital oil supplies that are increasingly prone to shifting sands.

A renewed Get Britain Building campaign is urging the government to support SME builders

The UK economy could see a £94bn return by buying UK produced materials, and building new homes using local builders. That was the message from the launch of the latest phase of the 11-year old Get Britain Building campaign. The Building Alliance, the Builders Merchants Federation, and the Federation of Master Builders, came together at the World HQ of JCB, to call for a major investment in our existing housing stock, to help achieve the government’s Net Zero Carbon target by 2050 and to encourage owner-occupiers to adapt their homes to meet changing needs. Addressing the skills gap is another priority area, with the campaign calling upon Government to work with the industry and educators to increase the take up of construction apprenticeships and introduce an upskilling programme to encourage continuous improvement across the sector. Commenting on the campaign, Mike Leonard, CEO of the Building Alliance said:

“We are at the start of a new decade, with a new government that has a unique opportunity to build our way to success. Investing in critical infrastructure, public and commercial buildings and housing will support long term economic growth, create jobs and promote social inclusion. We currently manufacture 80 per cent of the materials we use to build new homes in the UK. No other industry can rival this. We must continue to invest in UK manufacturing and support local builders to enjoy the huge economic multiplier that results.” Brian Berry, CEO of the Federation of Master Builders adds. “The Government has ambitious targets around building a million new homes and reaching a low-carbon standard for new homes by 2025.” “Master Builders stand ready to meet these challenges.” FOR FURTHER INFORMATION ON GET BRITAIN BUILDING VISIT WWW.RDR.LINK/BP010

A survey has found that, as a whole, UK tradespeople lose out on more than £929 million every year due to issues in financial planning

A new survey by Dakea questioned 500 tradespeople around the country and discovered that financial admin issues are hitting them where it hurts – in the pocket. 421,160, or nearly one-in-five, tradespeople are missing out on hundreds of pounds when filing tax reports due to missing information, mis-management of expenses and lost receipts. This totals £929,028,750 in lost revenue across the industry. On average, individual tradespeople in the UK are down more than £375 per year because of these mistakes, an amount which rises to £975 for local building firm bosses. A lack of up-todate business skills was identified as a factor, as only 41 per cent of those surveyed said that they used digital technology to carry out financial processes.

A recent study by Dickies Workwear has delved into research around the best UK regions for tradeswomen.

FINANCIAL TIMES woman’s hour

Whilst the construction industry can still be often stereotyped as a “maledominated” profession, especially taking into consideration an overall UK 5.6 per cent gender pay gap for the industry, some regions do perform better than others. The top areas for female construction workers were the North East – where weekly pay was the second-highest (£1,081), the average weekly cost of living was the lowest, (£408.30), and the average price of a house was £151,206 – with the West Midlands coming in at number two and Scotland third.

News IT’S A GAS!

VAN-TASTIC!

Baxi Heating is calling on the Government to mandate hydrogen-ready boilers for all new gas boiler installations by 2025.

The commercial vehicle market is enjoying growth in 2020, according to the Society of Motor Manufacturers and Traders (SMMT).

Responding to a recent report from the Hydrogen Taskforce, the company is also calling for £1bn of investment to prepare the UK for hydrogen production, distribution and storage at scale, which will be necessary if the UK is to develop a hydrogen future and meet Net Zero. Jeff House, Head of External Affairs for Baxi Heating, comments: “The installation of ‘hydrogen ready’ boilers could begin long before 100 per cent hydrogen is available within a locality by utilising the existing natural gas network. Once hydrogen is available, the hydrogen ready boilers can be simply and easily converted to hydrogen without the need for a new heating system.’’ GET MORE DETAILS AT: WWW.RDR.LINK/BP014

Condensate Pro has called for all builds to have condensate pipes insulated as standard. The company has commented following a recent consultation from the Department for Business, Enterprise and Industrial Strategy (BEIS) setting out the UK Government’s plans for the Future Homes Standard, which includes a proposal to include more stringent build quality advice on pipework where it enter or exits a building. “If the condensate pipe connected to condensing boilers, or the pipes running to Air Source Heat Pumps are not fully protected properly, they may be at risk of breakdown or not running efficiently,” says Dave Smith, Managing Director of Condensate Pro.

Compelling deals on the latest models, and a release of pent up demand, led to a 5.9 per cent increase in the first month of the year. Small vans weighing less than, or equal to, 2.0 tonnes and midsized vans weighing more than 2.0 – 2.5 tonnes led the charge, with double-digit growth for both segments at 26.3 per cent and 41.7 per cent respectively. 4x4s experienced a moderate growth of 6.3 per cent while pick up registrations fell 9.7 per cent and larger vans weighing more than 2.5 – 3.5 tonnes remain stable at -0.9 per cent.

GET A LOADER THIS!

JCB today celebrated a unique milestone as its 750,000th backhoe loader rolled off the production line. The landmark machine was driven off the line at the company’s factory in Rocester, Staffordshire – the very location where the first JCB backhoe was manufactured almost 70 years ago. It was in 1953 that company founder, the late Joseph Cyril Bamford CBE, conceived the idea of the JCB backhoe loader, which created, for the first time, a single machine which combined a front shovel and rear excavator arm. In its first full year of production in 1954, just 35 of the machines were produced and it took more than 20 years for the first 50,000 to be made. The company now manufactures backhoe loaders in the UK, India, Brazil and the USA. GET MORE DETAILS AT: WWW.RDR.LINK/BP018

The number of new homes registered to be built per annum in the UK has risen by more than 80 per cent over the last decade, according to the NHBC Over the ten-year period (2010 – 2019), a total of 1.4 million new homes (1,405,771) were registered to be built across the UK. These figures represent the first complete decade since the financial crash in 2007/08. In 2019, 161,022 homes were registered with NHBC, an 81 per cent increase on the 88,849 homes registered a decade ago (2009), making 2019 the strongest year for NHBC new home registrations since 2007. Compared to the previous year, the number of homes registered in 2019 was up 1 per cent. Growth was driven by London, where new home registrations increased by 37 per cent, with both the capital’s affordable and rental (+42 per cent) and private housing markets (+33 per cent) performing strongly. The Build to Rent sector had another positive year with registrations up 57 per cent in 2019 compared to 2018. FOR MORE INFORMATION VISIT: WWW.RDR.LINK/BP019

“A step in the right direction” is how the FMB describes the creation of a New Homes Ombudsman “While welcome, the drive towards ensuring quality for the consumer cannot be fully achieved without an industry-wide adoption of a licensing scheme,” insists Brian Berry, Chief Executive of the Federation of Master Builders (FMB). “So long as any company is legally allowed to undertake construction work in the UK without having to demonstrate a minimum level of competence, homeowners will remain at risk from rogue builders and poor service, leading to the sorts of complaints that the New Homes Ombudsman has been established to address.” TO VIEW THE FULL LISIT VISIT: WWW.RDR.LINK/BP027

Professional Builder, Regal House, Regal Way, Watford, Herts, WD24 4YF. Through our extensive manufacturer network, Professional Builder has access to some of the best technical brains in the industry. If we don’t know the answer to a building-related problem ourselves, we almost certainly know someone who does. If something is troubling you, or if you have any other comments on the world of building, let’s hear it.

PUT THE BOOT IN Dear Professional Builder

I’m not a big letter writer but I think this is point that needs making. I was at a car boot sale with the wife on the weekend and, amongst the usual tat, one guy had a boot full of power tools. This wasn’t DIY stuff – pretty high end professional, in fact – and there was a fair bit of it. Whilst I wouldn’t want to accuse anyone of handling stolen goods without due cause, I know just how it feels to be relieved of what amounts to your livelihood. I was working away from home on a job, when I had over £1,500 worth of kit stolen from the back of the van. Given that I was staying in a hotel, it just wasn’t possible to take it out for safekeeping, and the police weren’t interested. I’ve subsequently heard that this is a favourite target for thieves for precisely that reason – they know the tools are in the vehicle – and a lot of larger companies are now telling their employees not to leave their vans in hotel car parks. Point being that the kit I lost could well have ended up in a car boot sale just like the one I was at – it’s all pretty galling. ● Graham Buckhurst, Stockport PB: With tool theft reaching epidemic proportions this is a subject we’ve been covering in every issue for some time now. Whilst there are practical ways that builders can protect themselves, it remains the case that, whilst there’s an appetite for cheap, no-questions-asked second-hand goods, then there will always be those that will be willing to feed it with stolen property.

HEAVEN HELP US! Richard Vincent of Federation of Master Builders (FMB) award winning family building company, R Vincent and Sons of Durrington, Wiltshire has quite rightly taken us to task over a photo we used in the letters page last month to illustrate a tale of woe involving a cowboy customer. In fact, we couldn’t have chosen a more inappropriate picture if we had tried because, not only did it have nothing to do with the story, but it was actually one of a delightful cottage extension Richard and his team had undertaken. Indeed, on a previous project in 2006 the firm was awarded the FMB Heavenly Builder Award for demonstrating exceptional levels of customer service to a customer who was recovering from a major operation. We unreservedly apologise to Richard for any embarrassment caused, and look forward to reporting on more examples of his exemplary work, and excellent customer relations in the future.

OUT TO GRASS Dear Professional Builder

I’ve been asked to quote on a flat roof extension, which would very much be a standard job for us, but the client is keen on a green roof. I don’t particularly want to walk away from the work, especially as how I can see this could be a growth area in the future for a west London based business like ours, but I’ve always thought of it as a more of a specialist contractor’s preserve. Are there any recommendations for a system we could get started with? ● Richard Trentham, Twickenham PB: There are actually modular systems out there these days which are very straightforward to install. Of course, you’ll need to make sure that you’re designing in a roof with the structural integrity to take the extra weight. BRITISH MANUFACTURER, WALLBARN WOULD BE A GOOD PLACE TO START VISIT: WWW.RDR.LINK/BP029

GOOD AS NEW Dear Professional Builder

We’re a small company with just a few lads working for us, who’ve mainly worked on extensions over the years, but we have in the past acquired plots of land and undertaken a couple of our own developments. Ours were relatively high end properties that were built to a decent spec, which from our perspective makes recent reports of the issues with the standard of new build housing even more disappointing. It seems that a lot of the nationals are focusing on quantity rather than quality, and I understand that some of the office to residential conversions that have been springing up in recent years are a particular concern. We’ve heard some horror stories ourselves, with one new proud homeowner I know even discovering that the foul drains on their expensive south east home weren’t actually linked to a sewer. It’s unfortunate for the SME housebuilder that the whole industry gets tarnished as a result. ● Jeff Harrison, Stowmarket, Suffolk PB: There is certainly an argument that making the new build housing sector more accessible to smaller building firms will not only increase supply, but also raise standards. What it will take is an administration in Whitehall that’s prepared to make a concerted effort on the availability of land, reform what is often an unduly complicated planning system, and improve access to finance. It’s still relatively early days for this particular Government, of course, so we watch with interest.

FIGHTING

TOOL THEFT

Campaign

TOGETHER

Carpenter, Jim Marshall has developed a new device for securing your batteries and chargers on site.

ASSAULT ON BATTERIES! s any tradesman will know to their cost, replacing lithiumion batteries on cordless tools can be an expensive proposition, and if light fingers relieve you of them before their time has come, then the unexpected additional expenditure can be particularly irksome. When power tools are not in use they can be secured back in the van, or in any one of the many storage solutions currently on the market. If you are to work at your most productive, however, a replacement battery will often need to be charging close at hand, which makes it particularly vulnerable to the opportunist thief. Suddenly lose the power that drives your tools, and your ability to do your job that day is also somewhat compromised, with the loss in earnings that might entail. So what to do? Bitter personal experience is motivation enough for many a tradesman to find their own solution and carpenter, Jim Marshall was given just the incentive he needed. “It’s actually something that’s happened to me a few times in the past,” laments the Hampshire-based chippie. “On some sites there’s just nowhere where you can securely charge a battery – and they could end up 100 metres away and well out of view. They’re just such easy things to pick up and pocket, and there’s no way of knowing who it might have been. We were

working on joists on a housing development one day, and we had to plug our batteries into charge in a container down below. When I went back to retrieve one of mine I discovered they’d all gone.” Builders are by their nature problem solvers and, determined not to fall victim again, Jim initially came up with his own makeshift solution. “I quickly developed a rough protoype, that served as temporary solution. In truth, it wouldn’t have been

difficult to rip it open, but the extra time it might take to do that was deterrent enough.

Whilst many fledgling inventors have found the journey from that light bulb moment to the finished product a long and often tortuous one, Jim was able to move quickly, sourcing a local CAD designer who could bring his rough sketches to life, and enlisting a manufacturer who could produce the first prototypes, all within the space of a year. Jim charts the evolution of the concept: “A key principle of the product is its portability, so we went through a few versions before we got it down to a good size, and the finished version is now just 8kg. Batteries will obviously generate heat when they’re charging so there needed to be adequate ventilation built into the design. Thanks to the multiple plug hole and cable slots, it can be orientated in any number of ways on site, and there’s a whole array of mounting holes in order to fix it down, either through the base or via the back panel.” It is an old adage but one with which it is difficult to disagree, because the simplest ideas really are often the best. Once the SafeCharge is made secure, all a tradesman needs to do is place the chargers inside, feed the plug through the access holes and power up. Close the lid, secure it using a padlock, and the peace of mind of knowing that your batteries are safely stowed is assured. “Probably the best testimony I can give it is that it’s a solution that’s definitely worked for me,” concludes Jim, “and a SafeCharge is now a permanent fixture on the back of my van.” FOR FURTHER INFORMATION ON SAFECHARGE VISIT: WWW.RDR.LINK/BP031

AT A LOSS Over the next two issues we will be highlighting the impact that a main contractor’s sudden collapse can have on small building firms. This month, Professional Builder’s Lee Jones talks to carpenter Simon Huddart about his experiences. n recent years there have been a number of high profile incidents of large-scale bankruptcy in the building industry, not least Carillion, which collapsed owing its supply chain a colossal £2 billion. That was the largest liquidation in UK history, affecting up to 30,000 smaller firms, and was indicative of the seismic shocks that can, with little warning, swallow up sole traders and SMEs. Given the industry’s reliance on subcontracting, small construction companies are uniquely vulnerable, as Kent carpenter, Simon Huddart can testify. “I started out just working on my own, when a larger contractor offered me a couple of new builds,” explains the 36-year-old chippie. “It wasn’t a job I could do without help, so I took on two other guys. More work like it came along, and we fairly rapidly had seven or eight employees on our books.” Tradesmen will know it as ‘a knock’ but it is a phrase that scarcely does justice to the devastating impact it can have on a business owner who has painstakingly built up their firm, as Simon recounts. “We’d been occupied on a number of jobs in central London for a contractor with as solid a reputation as you could wish for. Not only had they been trading since the

18 APRIL 2020 PROFESSIONAL BUILDER

Part one 1940s, they also held a royal warrant for building and decorating services to the Queen. They’d set up a new build division, undertaking very high end projects, and it was good work for us. Then, without any warning whatsoever, they suddenly went into liquidation.”

Out of the blue

With carpentry contracts and workers on two different sites, Simon was left cruelly exposed. “There was no inkling from anyone in the company that they were in any way in trouble. In fact, just a week before we found out, they were pushing me to start on another job.” On that occasion, the total loss amounted to £33,000, with little prospect of retrieving any of what was owed. When a main contractor goes to the wall, whatever funds remain are first settled on the likes of HMRC and the banks, leaving sub-contractors like Simon a long way back in the queue. “We received a letter

from the administrators listing all of the failed company’s liabilities, including our own claim. I was eventually offered 4p for every pound, but even that has failed to materialise. I’ve since been getting letters around every six months for the last five years, which supposedly keeps us informed, but trying to contact them in return is virtually impossible.” The result was a drastic downsizing in his operation, but Simon was able to battle through and continue trading. Eager to protect himself against similar future shocks, he then investigated what resources exist to protect sub-contractors against a main contractor’s bankruptcy – only to be disappointed. “There are insurance policies available but the premiums are so eye-wateringly expensive, you’d quickly be paying out more than you’d ever be owed,” he laments. “Similarly, invoice factoring is an option in other sectors but, because construction is such a high risk industry,

“There was no inkling from anyone in the company that they were in any way in trouble. In fact, just a week before we found out, they were pushing me to start on another job.”

it’s not even offered to the likes of us. Not only that but I’ve never been paid on time by any main contractor I’ve ever worked for. You only ever see the profit in a job two or three months after it’s finished and if something like this happens then that’s completely wiped out.” The predicament of Simon, and millions like him, is exacerbated by that perennial problem of late payment. As a result, if the worst does happen, subcontractors are owed a disproportionately large sum of money. At the time of their demise Carillion were settling invoices on terms of 120 days and beyond. Whilst that would be amongst the most unscrupulous of examples, there are still far too many companies who are not paying their subbies even close to quickly enough. “It took about two years to fully

recover, and we then started to pick up bigger contracts, to the stage where, just a few months ago, I was employing around 22 carpenters, and at our peak we turned over £620,000 in a year’s trading. We were starting to feel like a real success story when disaster struck once again.” This time it would be an email at 6:30 on a Monday morning that would deliver the news. Simon was abruptly informed that the main contractor he was working for had gone bust, and all sites were closed. He was left £48,000 in arrears with little prospect once again of any recompense from the administrator. Indeed, on this occasion it was a loss from which his company, Huddart Carpentry has been unable to recover.

Own Boss

Simon is still working as a carpenter, a job from which he draws genuine satisfaction, but is determined that he will not be stung for a third time. Instead, he now concentrates on his own small, residential new build developments, where he is both the client and builder. “I’ve been wracking my brains to see if I could have done anything differently,” concludes Simon, “but it just seems to be down to luck whether this happens to you or not. For the smaller guys it’s very frustrating knowing that you’re so far down the food chain you’ll never see any of your money back. I don’t know what the answer is, but there must be some way of ensuring that a contractor has the money to complete a contract before they start it, or if there was a means to make insurance policies more affordable.”

“I don’t know what the answer is, but there must be some way of ensuring that a contractor has the money to complete a contract before they start it, or if there was a means to make insurance policies more affordable.”

So is there anything you can do to protect yourself? There are certainly no easy answers and, as Simon has discovered, once a main contractor does go into liquidation there is very little chance of recouping outstanding debts. Next month a leading law firm provides its counsel on what construction companies can do to at least be forewarned – and hopefully forearmed.

SPECIAL REPORT FLOODING

THAT SINKING FEELING The increased frequency of extreme rainfall events and consequent flooding means new approaches to flood resistance and flood resilience – namely water entry’ or ‘water exclusion’ strategies – are needed, says Hudson Lambert, Director at Safeguard Europe.

here’s no doubting that the UK is increasingly subject to extreme rainfall events, regardless of the arguments about the nature and causes of climate change. These extreme rainfall events put the UK’s infrastructure under great pressure, and urban and suburban flooding is now much more frequent. According to the Environment Agency, more than 5 million homes in England and Wales are at risk of flooding – a point grimly made only this February, when the agency issued a record 594 flood warnings across the country. The crucial need to contain and control rainfall – to protect people and property – is leading to more stringent legislation and standards; impacting upon authorities, developers and contractors and the design elements necessary to better manage these extreme events.

It has been the case that design solutions for flooding were described as either ‘flood resistant’ or ‘flood resilience’. However, use of these terms had become muddled and occasionally used interchangeably. Consequently, less mistakeable terms are now being employed, namely: ‘water-exclusion strategy’ (i.e. resistance), and ‘water-entry strategy’ (i.e. resilience). A ‘water-exclusion strategy’ house is built so that water cannot get into the building and cause damage. A ‘waterentry strategy’’ means constructing the

house so that although water may enter, the impact is lessened, structural integrity is maintained and drying and cleaning is made easier. The likely depth of flooding will impact on the choice of design. For low water depths, a ‘water exclusion strategy’ typically is recommended. A ‘water entry strategy’ is needed for higher water levels: a difference in water level of over 0.6m between inside and outside can cause significant structural damage to standard masonry buildings. In practice, a pragmatic combination of

SPECIAL REPORT FLOODING

both is taken because it is often either prohibitively expensive or impractical to provide a completely flood-resistant building – especially in cases where flood protection is being retrofitted to existing buildings.

Designing in flood resistance

In a new-build situation, the best way to stop water penetrating is to ensure that all concrete used is waterproof and to seal all construction joints with specifically designed proprietary tapes. Services coming in through walls and floors should be designed to be watertight. As a second line of defence, and if budget and circumstances allow, a cavity drainage membrane can help with the management of flood water. A cavity drainage membrane, such as Oldroyd Xv Eco White (partially made from recycled fishing nets), directs the water down the walls into a perimeter drain with the water running to a sump where it can be evacuated using a pump. This type of approach is also popular as a retrofit measure to existing buildings, used in combination with measures to upgrade the resistance of the existing masonry such as tanking and repointing.

Designing in flood resilience

When designing for flood resilience, the goal is to make it as easy as possible to clean the interior of a house after a flood. Floors and walls should be finished with an easily cleanable surface such as tiles. If the floor surface isn’t water compatible it should be easy to take up and replace. Water compatible doors and

“Apart from floor coverings and joinery, it is interior decoration that can take the biggest hammering – especially where walls are finished with gypsum or lime based plasters.” woodwork should be considered. Electrical circuits and sockets should be situated above the expected water level and in a kitchen, appliances can be raised up off the floor. Apart from floor coverings and joinery, it is interior decoration that can take the biggest hammering – especially where walls are finished with gypsum or lime based plasters. A new report from the

University of Portsmouth – The Effect of Moisture on Plaster Performance – supports the use of damp-resistant plasters instead. This cost-effective system utilises breathable, moistureresistant plasters to allow the fabric of a flooded building to dry out whilst providing a durable finish that will be resilient to future flooding. Moistureresistant screeds have also been developed using similar technology. After a flood, you can – for all practical purposes – simply hose down and sterilise the wall. The make-up of these plasters means they have large pores and a high pore volume. This allows salts to form within the plaster rather than on the surface; and the high pore volume results in high water vapour diffusion (breathability) and higher thermal resistance, reducing the risk of condensation.

Vital details

When considering the right combination of measures and products, it may be necessary to get specialist advice from a consultant or from the technical team of a supplier such as Safeguard. As with any system designed to protect from or manage water, it is vital to get the detail right at the design and installation stages.

SPECIAL REPORT GARDEN STUDIO PROJECT

Professional Builder visits regular reviewer and skilled carpenter and joiner Ollie Allen, who is building a studio in his back garden, with a little help from us, of course.

Garden Variety t’s surely the dream of Professional Builder readers across the country, to build yourself a space in your own garden where you can unleash your creative potential, get hands on with some raw materials and while away the hours with a tool in your hand, the radio on and maybe even a mug or two of tea on the side. Sure, some of the more jaded of our readers may see no difference between that dream and their normal working day, but there can be no doubting that Ollie Allen will be putting the studio to good use, stretching his imagination to the limit to craft ever more beautiful objects. With that in mind, we decided to get in on the action, rounding up some of our favourite manufacturers to chip in some products to help. We even got a chance to dig out the tool belt from the back of the cupboard and lend a helping hand. Here’s what Ollie had to say about the various products.

Norbord SterlingOSB Zero

Using Norbord’s SterlingOSB Zero was the first thought when it came to designing a modular and easy-to-build timber framed building. Compared to other sheet products on the market, it stands up to weather and humidity really well, it’s lightweight and even better on a typical build budget. Norbord use UK grown timber

and process and manufacture everything here in the UK, and it’s really good to know it’s not clocking up air miles – that makes for a more sustainable future for the building industry. OSB has long been a favourite of mine for building with – it cuts great without chipping and splintering, it’s uniform and it doesn’t move after installation, which is perfect for timber framing projects. We are using 11mm board to skin the exterior before cladding in shingles and 18mm board as the interior face. These two boards, combined with timber studs or PIR boards, make for a really fast and strong method of wall construction.

Norbord CaberShieldPlus

I knew I would have periods of time when weather would affect the build schedule, being in Yorkshire where it’s wet approximately 95 per cent of the time, and this build has been no different! So I turned once more to Norbord and their CaberShieldPlus system, once installed with their D4 adhesive, it’s rated for 60 days of bad weather. It’s perfect for those ‘roof off renovations’ or the first floor of an extension, especially when customers change roof window designs every other week! The flooring is super easy to install and has a tough and durable outer coating of melamine, similar to a kitchen workshop but textured for grip. Using the Polyurethane glue in the joints, it gives extra waterproof protection and keeps out the elements whilst you build the rest of the structure. I have found the boards easy to clean, which helps keep the dust levels down compared to typical dry chipboard flooring products.

Rockwool Insulation

Quickslide Flush Windows and Doors

The moment I saw Quickslide’s range of Flush Casement Windows and Doors I knew they were serious about design, architecture and functionality. Sleek and modern, and perfect for a new build or renovation project, these doors and windows have integrated perfectly into our project and will look great paired with the modern Cedar shingles we are using for the exterior cladding. Quickslide are another great example of British manufacturing and have invested in a new plant to manufacture this new ‘Flush’ range of products. We were lucky to have one of the first products off the new line, all built in Yorkshire too! I went for the standard multi-point locking system in Matte Black for that ultra-modern look. The units arrive fully built up, have protective corner packaging and are delivered by the company’s own team, so no worries about anyone on site smashing loose double glazed units, which is always a worry when receiving PVCu windows from suppliers.

Werner Ladders

We have given the Werner 72006 ladder a good run on our timber framing project and it’s proven an invaluable tool. There’s a lot of talk about ladders and concern with health and safety these days, which I think Werner have addressed nicely with the large and sturdy ‘basket/cockpit’ design. This allows you to stand at the top and reach at full arm’s length, whilst still being securely stood within a protective area on top of the ladder. It’s worked out really well for high impact work, such as nailing/screwing and sawing whilst at height. It’s pretty lightweight and easy to move, and slightly heavier than the aluminium counterpart, but does have that extra material for the standing area.

There’s a huge choice out there for off-the-shelf garden rooms and offices but I wanted to build something from scratch which was not only of everyday benefit to me and my family, but could then be offered as a package to other potential customers. Key to this is using standard sized timber products to reduce cutting, and materials which are all easily to access via my local merchant. It’s mostly been a weekend and spare evening project for me but, working flat out, two men could complete a building of this size comfortably in a week. And at a finished price that would seriously undercut those you see offered in the glossy brochures. Ollie Allen.

I chose 75mm Rockwool RW45A insulation because it’s specifically designed for timber frame applications and fits between 600mm studs perfectly. It has a ‘soft edge technology’ which allows for snug fitting – you simply pack it neatly into the stud pocket and it expands to fill out the gap in its own time. It’s packed in easy to handle bales and has been really simple to install, with great sound insulating properties, which is ideal for standalone buildings like this project.

Come what may

With the lighter evenings just around the corner and hopefully a break in the stormy conditions, Ollie was confident that the project would be completed in time for the May Bank Holiday. Needless to say, we will be heading up north again to check out the finished studio and find out what this human whirlwind of creativity has up his sleeve next.

SPECIAL REPORT INSULATION

“ACTIS” MAKES PERFECT

icture the scene. You’re at a school reunion. Little Timmy who used to be the shy, quiet one has become six foot something, with a chiselled jaw and a selection of holiday villas to his name. And the girl who always hid in the library to avoid PE is a world famous, best-selling novelist. Our recent re-acquaintance with insulation specialist Actis was a little like that. A lot has been going on behind the scenes these past five years or so – what with its successful partnership with LABC, the creation of a second CPD module to appease the clamouring throngs and the launch of an advanced new insulating breather membrane for roofs. We caught up with Actis UK specification manager, Dan Anson-Hart to chat about the changes.

You’ve clearly been busy. Tell us how all these changes are helping your business and, more importantly, your customers? Firstly, what’s the deal with LABC?

Dan Anson-Hart outlines the latest developments from Actis Insulation ACTIS: Well, we’re now into our third year of partnering LABC. Our aim is to help builders, architects, Building Control officers and specifiers get more insight into thermal efficiency. A lot of this is achieved through LABC’s monthly technical seminars, which take place at different spots around England and Wales. These involve a number of presentations from various industry experts, which all add up to three and a half hours’ worth of CPD training. Our session is on addressing the performance

gap with reflective insulation. The seminars are free and include a bonus free breakfast – so what’s to lose? They’re really popular and are often oversubscribed. Another really important project we’ve recently worked on with LABC is a Registered Construction Details tool. It’s one of a group of such tools aimed at helping builders achieve as-built performance. The one we devised is for thermal details. It gives a list of points to look out for during design and on site. The RCD drawings and documents can be fed into specifications for new projects and are also accessible on the go. Builders can link to installation videos while out on site, for example, ensuring the tool is useful at all stages of the process from specification to installation.

You mentioned that you offer training at LABC roadshows. You’ve also just launched a new CPD module. Tell us about that. ACTIS: Our initial module on addressing the performance gap has been incredibly popular, with take up increasing by around 50 per cent over the past year. We had people coming to us saying: “that was so useful and we want more.” So we obliged, and the one we’ve just released is about compliance. The first batch of Building Control officers who came along said it answered every single question they had on the topic. So, we’re pretty confident it’s going to be as popular as our first one. Obviously, it looks at compliance with Part L – conservation of fuel and power, but it also examines Parts B (fire safety), C (site preparation and resistance to contaminants and moisture), D (toxic substances) and E (resistance to the passage of sound). And it flags up tools which specifiers can use to ensure they make the correct choices to ensure compliance. This CPD, like the first, is around 45 minutes long, with a 15-minute Q&A, and is a chance to inspect insulation materials at first hand, and talk to us one-to-one about compliance and thermal bridging issues. A company can book one as a standalone, or as part of a wider event to which it invites people from related trades across the industry.

You used to have three core products in your Hybrid range – but we understand there has been a recent addition? Can you explain what this new one does and refresh our memories about the other three? ACTIS: The products are all CE marked, have LABC and LABSS registered details, LABC Warranty and Premier Guarantee approval, and are accepted by the NHBC when used in accordance with the certification. Hybris is a honeycomb style insulation, which comes in various thicknesses, can be moulded into gaps and is incredibly quick, clean and easy to install. In fact, those qualities apply to all our products. Then we have our insulating vapour control layer HControl Hybrid and insulating breather membrane Boost R Hybrid. The new (ish) addition is Boost R Hybrid Roof which – surprise, surprise – is specially designed for roofs. It has a lap, and built in adhesive tape, and comes in larger rolls, which covers 15sq m. There’s even a series of bite sized video tutorials which look in detail at how to install the product.

Anything else our readers need to look out for over the coming months. ACTIS: Well, we’ve been busy giving our feedback, alongside the Structural Timber Association, on the Government’s Part L

revision plans, which will feed into the Future Homes Standard. So we look forward to that later this year, when the chosen changes come into effect. We’re continuing to bang the drum for an increase in timber frame homes as a key way to help us address the chronic housing shortfall (they’re about 25 per cent faster to build than brick and block, you see). And, of course, we hope the wise words of Mark Farmer, the Government’s new Modern Methods of Construction champion, will bear fruit. He’s something of a guru to many of us in the industry.

SPECIAL REPORT PART L

THE BEST PART Kingspan details what you need to know about the latest Part L proposals f you handle any housebuilding in England or Wales, then you may be aware of the recent consultations on changes to Part L (and F) of the separate Building Regulations in each country. Part L sets the energy performance targets for buildings, and with pressure on to cut carbon emissions, the revisions are being fast-tracked to come into force by the end of the year. Whilst the changes are yet to be finalised, the short timescale means it is important to get to grips with these proposals – and how they may affect your projects.

What is changing?

Part L (conservation of fuel and power) and Part F (ventilation) of the Building Regulations set the legal requirements which properties need to meet. The consultations also affect Approved Document L1A (ADL1A) and Approved Document F, which aren’t mandatory but provide guidance on how to meet the new Building Regulation requirements. Keep in mind that whilst the consultations are focused solely on new build domestic properties, further consultations are expected for the requirements for existing buildings and new non-domestic projects.

The Options

The English and Welsh consultations both offer a couple of uplift scenarios over their current carbon emission targets. In England these are 20 per cent or 31 per cent (preferred) whilst Wales has opted for more ambitious targets: 37 per cent (preferred) or 56 per cent. Up until now, carbon emissions have been the principal measure used to decide whether a building complies with Part L. However, as the energy supply is decarbonised, emissions are becoming a less accurate measure of how energy efficient a property is. For this reason, both consultations introduce a new principal performance metric — Primary

30 APRIL 2020 PROFESSIONAL BUILDER

Floor (W/m2K) External Walls (W/m2K) Flat and Pitched Roofs (W/m2K)

Backstop U-values Wales 2020 0.15 0.18 (0.21 in flats) 0.13

England 2020 0.18 0.26 0.16

Table 1 - Backstops for building fabric elements within Welsh and English Part L consultations.

Energy — with carbon emissions retained as a secondary performance metric. Primary Energy is generated through a calculation which factors in the energy demand for the property, efficiency of the heating technologies used (i.e. gas boiler) and the amount of energy used to get the chosen fuel ready for use (i.e. extraction, refinement and transportation).

Primary Problem

Whilst the introduction of Primary Energy makes a lot of sense, the way it is used in the English consultation is raising some eyebrows. The current English Approved Document L (ADL) uses a Fabric Energy Efficiency Standard (FEES) to limit the energy demand for a property. In the proposals, however, the FEES has been dropped. At the same time, the proposed worst-case backstops for fabric

performance are much laxer than the Welsh targets shown in the table above. In theory, this could allow English homes to be constructed to the worstcase backstops across the board, with higher heat demand than one built to the current standards (and therefore subject to FEES), providing that this is compensated for by using lots of PV generation.

Fabric and Detailing

Overall, the better approach would be to take a fabric-first approach, ensuring all elements are well insulated whilst retaining the ability to simply upgrade the building by adding energy generation in the future. Whilst not compulsory, the suggested building element U-values used within the notional building for the Welsh consultation (table 2) offer a sensible starting point.

Table 2 – Selected notional dwellings building parameters

Thermal bridging and detailing have also received attention as poor workmanship in this area can undermine the performance of the whole building. Under the proposed changes, the Approved Construction Detail’s associated generic psi-values (measure of heat loss through a junction) would be

ditched, the global backstop default thermal bridging level would worsen and, unless developers have modelled/calculated psi-values available, the somewhat poor individual junction backstops will have to be used. This means that paying attention to detail will be very important to overall compliance. It’s important to keep in mind that the new ADLs are designed as a step towards even tougher requirements in 2025. As such, they should be seen as an opportunity to tool-up. By aiming for the more demanding fabric targets now, and

ensuring detailing and installation is up to scratch, the transition to the next targets will be much more straightforward.

USING YOUR BLOCK Aircrete may be one of the most widely used products on sites across the UK, but there is probably more to the product than you think. Jenny Smith-Andrews, Marketing Manager of manufacturer H+H outlines some of the information and training on offer.

elcon Blocks, in their very recognisable white and green wrapping, are a familiar site across building sites large and small, and block laying is probably one of the first skills you learnt. But do you know about using aircrete blocks for foundations or party walls? And have you ever built a house using our Thin-Joint system? So, if you are interested to know how aircrete is made, how it is best handled and cut, its thermal efficiency or sound insulation properties, then the H+H Online Academy is a great place to start. The academy was originally set up to help merchant counter staff understand the many benefits of building with aircrete, and enable them to give competent and cost saving advice to customers, but H+H quickly realised that builders like to find stuff out for themselves. Anyone can now register for the academy, and go through the training materials online. It doesn’t take long, and even if you use aircrete blocks every day the chances are that there will be something that is new to you as you go through the programme. Since YouTube is generally a first port of call for any of us trying to find out how to do something, H+H has also developed a series of animated videos showing how

to use Celcon Blocks for foundations, party walls and spandrels. There is even a video showing the use of Celcon Elements – storey-high aircrete panels. Elements are proving to be of huge interest for larger housing schemes and are likely to become an increasingly common feature of housebuilding over the next few years. Developers are seeing Elements as part of an offsite / MMC solution that combines the speed and standardisation benefits of prefabrication with the familiarity of a product whose performance is well proven. As the industry focusses more on modern methods it will be increasingly important to understand how aircrete solutions fit in with the MMC agenda. One of the biggest challenges facing the building industry in the next few years is recruiting the next generation. H+H takes the view that the industry needs to work together to help recruit and train newcomers and, like many manufacturers, it does this by supporting colleges

teaching NVQ bricklaying courses. Block laying is taught as part of the basic NVQ Level 1 and 2 bricklaying courses but Thin-Joint features only as an option, so H+H has a rolling programme of visiting colleges in order to demonstrate how the system works. The students are typically surprised and impressed when they find out how quick the blocks are to lay using ThinJoint, and how high the walls can be built in a day. When they consider that they are likely to be paid piecework for their block-laying it doesn’t take them long to figure out that using Thin-Joint could be a big earner for them. Thin-Joint is a system that is not used as much as it could be on UK building sites, but that might change now with the growing pressure to use Modern Methods of Construction (MMC). Thin-Joint is defined as an MMC and therefore projects using it may attract government funding, which could be an attractive option, particularly for housebuilders. If Thin-Joint is something that you’ve

heard about but not tried for a while, there is a whole series of step-by-step guides in the H+H YouTube channel demonstrating exactly how the system works and what tools and techniques are needed. Over the years it’s turned out that Thin-Joint is particularly attractive for self and custom build projects. Homeowners like the airtight performance, and the speed of construction is great for the contractor. Supporting this type of project is the job of the H+H training team who will go to site and demonstrate the Thin-Joint technique, making sure the whole site team is up to speed. And if it’s a skill you’re looking to introduce into your company, H+H is also able to set up a training day at one of the block factories so that a team of block-layers can get to know the system. An option of Yorkshire or Kent for this type of site demonstration gives flexibility for location. And if this hands-on training sounds too time consuming, it’s also good to know that technical information about aircrete products is literally at your fingertips via the H+H Brochure App which offers instant access to the most popular product literature. It all adds up to a pretty comprehensive range of training and information for block layers and building contractors however long they have been using aircrete.

t’s generally accepted that the first bricks were laid more than 9,000 years ago in Southern Turkey, and ever since the bricklayers’ tool kit has largely comprised a trowel, a level and a fair modicum of dexterity. Oh, and, of course, the humble spot board to keep the all important mortar close at hand. More often than not a random piece of wood or ply off cut usually does the trick, and in truth it’s one of those taken for granted items, a bit player in the overall scheme of getting the wall up. It’s a scenario routinely played out on thousands of building sites everyday but one that, if bricklayer Marc Foley has his way, the industry will soon, quite literally, be spotting a very different way of going about its business. He told us: “Like all brickies the priority has always been totally on laying as many bricks as you can to a given standard in a day and leave the muck and bullets side of things to the labourer. Their role is crucial to ensure a ready supply of bricks in the right place and a constant supply of workable mortar. So far so good, but that’s where even the best ones are let down by the tools of their trade in make-shift spot boards. These are constantly exposed to the rough and tumble of the site, harsh weather conditions and the effect of the mortar itself rendering them very quickly not fit for purpose.

36 APRIL 2020 PROFESSIONAL BUILDER

SPOT THE DIFFERENCE They say a leopard never changes its spots... but what about a bricklayer?! That’s a question which has been troubling brickie Marc Foley for years and one which he believes he is on the brink of answering in the affirmative.

036_PB_APR20_Layout 1 05/03/2020 15:57 Page 37

In a Spot

It’s not the labourers fault, of course, just the way it’s always been done for centuries, but the knock-on effect to the project is enormous, especially on big sites. For one thing the boards are heavy to lift onto the scaffold, absorb water, which in turn dries out the mortar, and makes it less pliable for the brickie to use. Being random off cuts, they are often different sizes, either too small to contain enough mortar and need constant topping up, or too big and block the scaffold. I put up with it myself for years and suddenly had a moment a couple of years back when I decided there had to be a better and safer way,” enthuses Marc. The answer is Flexi Block Spot, a high quality rubber cover which sits over a standard pile of bricks or blocks and provides a perfect clean non absorbent surface for the mortar. They are extremely pliable and light, a labourer can easily carry up to ten in a bag onto the scaffold and, of course, at the end of the day can be washed down and left in place for the next day’s building. They will also provide frost and driving rain protection overnight.

“The answer is the Flexi Block Spot, a high quality rubber cover which sits over a standard pile of bricks or blocks and provides a perfect clean non absorbent surface for the mortar.”

After working through a number of designs, and approaching some potential manufacturers, we came up with prototypes which I used on my own sites, and put out to some other builders I know in the area. The feed-back was tremendous, the usual stuff of being so simple why didn’t we think of it ourselves? Now with a patent and packaging in place we are ready to tell the world about it. “Of course, I am under no illusions that we can change so many years of practice over night. Bricklayers are a conservative bunch and with good reason, of course, but I really think we have something which will improve their ability to lay more bricks per day, which in turn means greater productivity and, of course, profitability on the job.” Like most things, it looks like Marc has that assessment spot on as well!

A CONCRETE CHOICE

oncrete offers builders and landscapers the flexibility to create a variety of elements for an outdoor space which require minimal upkeep. Recent innovations in moulding and setting techniques have boosted its versatility, allowing it to be used to create designs which tie in seamlessly with softscape features. From walls, planters and brick barbeques to paths and board-marked walls, the material offers an inexpensive way to create an outdoor space which is both practical and stylish.

Outdoor living

Concrete allows homeowners to maximise their outdoor living space in the warmer months. As the trend for extending the living space to the garden increases, landscapers and builders are exploring different ways to incorporate indoor elements into landscaping designs. Installing concrete furniture, such as a table or worktop, is a sure-fire way to infuse a stylish and alternative aesthetic into a property’s garden. These hardscape features can endure exposure

Simon Chudley, National Commercial Technical Manager at Tarmac Blue Circle Cement, discusses some of the benefits of using concrete in modern landscaping projects. to the elements and general wear and tear without scratching or cracking, whilst also remaining resistant to moisture, mould and insects. The simplistic nature of the material means it can complement most styles of outdoor area without feeling too industrial. The key is to suggest adding other warmer, natural textures like fabric or wood to enhance the space and avoid it feeling too cold. Adding inserts or inlays is a great way to personalise an outdoor workspace. Whether it’s small stones, pieces of glass or other materials that are mixed

throughout the concrete, these can all contribute to a stylish and liveable outdoor area. For furniture such as tables, which are generally long, slender, thin beams, it’s vital to use a product with adequate workability and flexural strength, such as Tarmac Blue Circle High Strength Concrete (40N) to prevent cracking, chipping and shrinkage.

Board marked walls

A concrete wall offers a durable, maintenance free and thermally retentive solution, which will stand the test of time. One of the aesthetic benefits of concrete is its ability to take on the texture of the forms into which it’s poured, making it possible to enhance its surface appearance with different finishes. Concrete is often used in conjunction with timber to add warmth and depth to the finished product. For example, using horizontal rough-board forms to shape

to use a high-strength concrete and you should suggest only polishing these areas up to three times to maintain a safe slip rating of R10. For decorative planters, you can grind up to nine times to achieve a completely smooth and polished finish.

and imprint the concrete with the grain of the wood. The combination of the two materials results in a contemporary and stylish looking wall in the garden. To ensure the longevity and standard of your work and cement your reputation, youâ&#x20AC;&#x2122;ll want to use a poured high-strength product such as Blue Circle High Strength Concrete (40N).

Brick barbeque

Simple to build and use, a brick barbeque can be an attractive addition to any patio area. As well as getting around the issues of rusting or breakage to metals, a brick alternative offers the added benefit of not having to find a large space to store the barbeque when not in use. Simply build a solid foundation, mark out the brickwork area and prepare a mortar to lay the bricks. Using a prebagged, ready to use mortar mix, such as Tarmac Blue Circle Quality Assured Mortar, simplifies the task even further, requiring only the addition of clean water.

The foundation for modern landscaping

Polished concrete

An increasingly popular choice for modern landscaping design is polished concrete. Its versatility, durability and affordability make it ideal for garden elements such as planters, pathways and patios. To further enhance the design, you can add unique elements, such as coloured glass, which will complement its simplicity. The polishing process involves using progressively finer grinding tools until you reach the desired texture. For high traffic areas, such a walkways or patios, itâ&#x20AC;&#x2122;s best

A 2018 report by WGSN highlighted that concrete is trending across trade shows and particularly with emerging designers. The creative possibilities of concrete are expanding, and tradesmen are using the product in original and inventive ways. Builders can tap into the growing trend by looking into all the possibilities that concrete has to offer in the garden.

NO DRAIN NO GAIN ACO Water Management’s Oliver Collins, explains the key drainage considerations for any professional builder. ach individual area within the home presents its own unique water management challenge. From the driveway and entrance to patios and gardens, there is no ‘one size fits all’ when it comes to drainage, especially if you want to maintain a high quality finish.

Driveway drainage

Aesthetically, the driveway is the first point of contact for many homes. Having a well-planned driveway that is both spacious and functional is very important. When working on a development that includes domestic driveways, selecting an

aesthetic drainage solution can not only help add value but also increase customer satisfaction. There is a range of drainage systems available which can complement garage threshold and the driveway entrances, helping to create an attractive space. However, it is important that the drainage is able to withstand the rigours of everyday pedestrian and vehicular use. Builders should look to utilise a channel which has a load class of B 125 or higher, which would be suitable for most driveways. This is due to the increased likelihood that delivery vehicles will drive over the gratings, meaning a structurally sound channel is used. Additionally, with the opportunity to ‘mix and match’ gratings and channels, through ACO’s ‘Complete the Look’ range, it is imperative that builders are not

tempted to pair an A 15 grating with a B 125 channel, or vice versa, as this will result in the load class of the system defaulting to the lowest grade.

Patios and pathways

Unlike driveways, patios and pathways can utilise an A 15 load channel assembly, unless it is likely that it will be driven over by a vehicle. Patios are an area where a developer can really deliver an aesthetically pleasing solution, to help provide an elegant and modern finish. From slate or porcelain to natural stone, the intricacies of patio projects should not be undermined by a poorly

blend finishes with substance, via the installation of threshold drainage products. Helping to create an attractive entrance to the home, threshold drainage is important here because it removes any risk of water ponding, which looks both unprofessional and can degrade the brickwork over time. The use of threshold drainage can help enhance the aesthetic appeal when combined with slimline stainless steel channels or doorway mats with anthracite carpet gratings.

selected, or lack of, drainage solution. An option to consider is our range of domestic drainage channels; HexDrain and RainDrain, which offer a ‘Complete the Look’ choice of grating styles ranging from contemporary stainless steel to discreet brickslot options.

Entrances

With patios and driveways, the entrance of a house offers another opportunity to

Garden spaces can also provide opportunities to housebuilders and developers. For domestic driveways and paths, where a natural grass or decorative aggregate finish is required to complement the landscape, for example, utilising a landscaping and attenuation system will help reduce the risk of potholes, rutting or grass damage. Systems, such as ACO’s

GravelGuard and GroundGuard are ideal for these situations. If installing domestic soakaways, it is important to ensure they comply with current Building Regulations concerning run-off from drives. If unsure, it is recommended that you speak with a drainage expert, who will be able to provide advice and guidance on the best option.

Final Thoughts

When working on a housing development, it can be all too easy to go to a local merchant and select one channel drainage system and grating for the whole of the project. However, to achieve the best finish, builders should seriously consider the different systems and types of grating that can be paired. Understanding the environmental impact, as well as the load requirements, is also crucial.

GREEN GIANT Michael White, Divisional Marketing & Development Director at Polypipe Civils & Green Urbanisation, explains how builders can make sustainable attainable with green assets he challenge of climate change – characterised by extreme storms, heavy rain and extended dry spells – means a new approach to urban drainage is necessary. Happily, technologies that optimise ‘green assets’ through extended water management networks, are now here. Regardless of differences of opinion on the nature, causes and severity of climate change, there’s no question that the nation is suffering more and worse extreme weather. Interestingly, annual rainfall only rarely exceeds 1,500mm a year – yet it is arriving in larger amounts

on fewer occasions, rather than falling gradually across the year, with all the problems that causes. As a result of major storms and associated heavy rainfall, drainage infrastructure struggles to cope and – as we’ve seen over the past few months – serious flooding is much more common. At the same time, we are also subject to longer and warmer dry spells which result in shortages of water for drinking and amenity use (e.g. hosepipe bans); and puts pressure on landscapes and ‘green assets’ – trees, lawns, green roofs and other planted areas. The crucial need to contain and

control rainfall – to protect people and property – is inevitably going to bring tougher legislation and standards in water collection and management; impacting upon local authorities, developers and contractors and the sustainable drainage systems (SuDS) techniques required to better manage these extreme events. Alongside this, environmental legislation is imposing demands upon local authorities and developers. Previously, a specialist area within building, ‘green asset management’ is now an essential consideration in design, and means we need to introduce systems that not only protect and nurture trees and other plants during dry spells, but also allows for more of them – ‘urban greening’ – where possible. Both these legal drivers mean a new approach to multi-functional SuDS is needed. This new approach is what Polypipe is calling – and is reflected in our recent company name change – ‘Green Urbanisation’; and will network water collection, management and storage, and green assets to deliver: enhanced flood and drought resilience, smart water usage and increased biodiversity. It also plays a valuable role in carbon capture and offset. Green Urbanisation is an evolution of Green Infrastructure and describes a move from conventional drainage and SuDS to an extended ‘water management network’ that supports landscapes across towns, cities, transport and commercial spaces. There’s an opportunity in the adoption of new technologies – such as Polypipe’s Permavoid sub-base replacement – to optimise such green assets within this new water management network. Traditionally, conventional drainage

PROFESSIONAL BUILDER APRIL 2020 47

047_PB_APR20_Layout 1 06/03/2020 10:55 Page 48

masonry materials & landscaping

networks were simply about removing surface water as quickly as possible to a sewer, receiving water course or to ground. Typically, these did not truly address volume management, so early SuDS schemes were primarily focused on controlling run-off quantity – basically, they increased ‘volumetric resilience’. But SuDS have the additional benefit of, where space allows, introducing green elements into the process. Their ‘green asset resilience’, however, is limited. During prolonged dry spells the plants are vulnerable to stress, regression, and dieback, potentially resulting in the loss of all their benefits. Appearance-wise too, a dry, brown and barren landscape is not one that appeals to anyone. The Green Urbanisation approach significantly improves both flood and drought resilience building-in captured water re-use and plant irrigation. High-load bearing sub-base replacement systems – such as Permavoid – allows rainwater to be captured and retained immediately below

the surface. Its lightweight, high loadbearing capacity means this can be directly installed under a road, trafficked podium deck surface or under a conventional green roof. This provides ‘source control’ – one of the key SuDS design objectives, where rain is managed as close to where it falls as possible. The better the source control, the more efficient and cost-effective SuDS become. Planting, from straight-forward grassed

areas to fully mature trees, can be supported anywhere across an installed area. In-built passive irrigation cones wick water into the sub-soil, maintaining, protecting and containing root systems within the designated planting area. In addition, Green Urbanisation allows for the re-use of water stored elsewhere in the system – with smart controls moving water around the network to where it is needed. This approach can be adapted to operate on a single house plot or small development site or across an entire river catchment. By combining SuDS with green assets, backed by components such as Permavoid, the sector now offers a comprehensive new generation of solutions to help tackle the challenging issues of extreme rainfall, flood risk and drought.

THE WASTE LAND A new development in recycled building materials is most certainly not just another brick in the wall. Professional Builder’s Lee Jones talks to the developer of the world’s first recycled brick.

f we are to continue along our present path many of the raw materials that we take for granted are either destined to become increasingly scarce resources, or environmentally insupportable. As we have reported in this issue’s Editor’s Viewpoint, even sand could soon be in short supply, whilst all the stages of concrete production currently account for anywhere between 4 – 8 per cent of global CO2 emissions. “If you look at the amount of virgin material we are still exploiting – and add to that the volume of waste we continue to generate – and it is clear that society is going to have a problem,” declares Professor Gabriela Modero. “That is the principle behind the K-Briq – it is the circular economy in action.” First conceived as an idea 10 years ago, civil and geotechnical engineering expert, Gabriela and her colleague Dr Sam Chapman, together with a team at Edinburgh’s Heriot-Watt University, have since developed a brick made from 90 per cent recycled construction and demolition waste. It’s composed largely of concrete, brick and aggregate, and the

50 APRIL 2020 PROFESSIONAL BUILDER

product is now in commercial production through Kenoteq – a clean-tech spin off from Heriot-Watt that specialises in lowcarbon building products.

Low Carbon

Crucial to the lighter tread of its carbon footprint is that the K-Briq uses no cement, and does not require kiln firing. Instead the material is air dried, which means it is said to account for only 10 per cent of the CO2 emissions of a

conventional clay brick. The process of manufacture is jealously guarded by Kenoteq, but it is a product that has already won plaudits, with a new pavilion at the Serpentine in London’s Hyde Park shortly to be built from K-Briq, and a number of other projects in the pipeline. Continues Gabriela: “Commercially, this is a solution that will find favour with developers because there’s considerable flexibility in terms of colour, with a range of finishes available from recycled pigments. Not only that, but the quality of the brick, in terms of durability and longevity will also be apparent, whilst it also has a higher U-Value than its clay counterpart.” Indeed, developers and the wider industry will increasingly need to demonstrate their environmental credentials to new and existing clients, and it’s not just in its thermal insulation properties that K-Briq can score points on sustainability. The Scottish government has equally set ambitious targets for housebuilding in the years ahead – with up to 50,000 new homes a year the current target and, given that the product will be produced north of the border, that

050_PB_APR20_Layout 1 06/03/2020 12:16 Page 51

means the energy miles in supplying those sites will be reduced. Gabriela explains the development process: “We have the resources of a university at our disposal and, because we began in a controlled laboratory setting, we’ve been in the fortunate position that we could continuously and extensively test the product in-house to the building standards and beyond. What that process produced was a product that looks like a clay brick, and is roughly the same weight, but has a inherent sustainability benefits. It’s also more breathable, which means it can contribute to keeping a property warm in the winter and cooler in the summer. Scaling the product up from a laboratory to a position where we are now producing thousands has been an interesting journey, but we’re now working towards BBA certification.”

For Kenoteq, however, this is just the beginning, and there are ambitious plans to introduce similar innovations: “The K-Briq is the first to enter the market, but we actually have a whole portfolio of products at different stages of development. They will be developed with the needs of the industry in mind, but

equally along the same low carbon principles.” With investment in machinery that can produce up to 3 million bricks a year, the objective is to supply the builders’ merchant network, with a product that demonstrates just what can be achieved from waste materials.

Dragon Equipment’s Jeff Haines with the machine he has developed – the CR300 Concrete Crusher

ENTER THE DRAGON

With the Dragon Equipment CR300 it’s crush hour on site. Professional Builder’s Lee Jones talks to the engineering expert behind this new crusher.

ecycling waste on site has been a staple of large construction projects for some time, but it would be fair to say that the local jobbing builder has hitherto lagged behind. We now live in a society where waste is a commodity in its own right, and when builders are removing existing structures, before they erect a new extension or landscape scheme, for instance, they can find themselves very rich in it indeed. It’s not just about keeping Greta happy, of course, because if you do the maths on skip hire, and the cost of importing sub-base onto site, then the commercial advantages of producing your own material in situ starts to make sense. That was just the scenario for experienced engineer, Jeff Haines when he and his son were removing a brick and concrete outbuilding from his rural Suffolk home, and, just a year on, the result is

Dragon Equipment’s CR300 Concrete Crusher. With a wealth of experience earned as the head of the R&D department of a leading wood chipping equipment manufacturer, he had the expertise to quickly assemble a prototype. “With limited access to our property hiring a larger crusher wasn’t really feasible,” explains Jeff, “but from original drawing to working solution, I was

able to get something that would serve our purpose in just two weeks, and it enabled us to get rid of the rest of the building in just one day.” Jeff then realised that a smaller and more mobile crusher could find a place in the repair, maintenance and improvement sector, and set about making his initial effort commercially viable. Just a year on, with mark five of that first machine now

available to buy, builders can reap the benefits of recycling hardcore on even the smallest of sites. “With a level of productivity you’d expect from a much larger piece of kit, everyone I’ve shown the CR300 to has been impressed by just what can be achieved from such a small machine,” enthuses Jeff. “The guiding principle of the design has been portability, ease of use and safety. Because it’s a tracked unit, and fits through a standard 700mm doorway, for example, there’s virtually no job that you can’t access. Even if you’re prevented from getting into a back garden directly you can simply lay some tarpaulin down in the house, track it through the front door and out the back, and it’s equally straightforward to get around even tight corners. It’s very easy to use, and is protected by some very clever technology.”

ECU Protection

The hire market can be a hard task master for any piece of equipment, but, unusually for such a compact unit, Jeff has equipped the CR300 with protection in the form of a programmable Electronic Control Unit (ECU). Not only will that prevent the machine from being abused through overloading, but it is also possible to dial into it remotely in order to check its status, and diagnose faults. That same function can be used to set up geofences, where an alert will be issued if it is taken out of a prescribed area, a vital security weapon in the wake of increases in on site theft. “Landscape gardeners who are pulling up patios and pathways will find a particular use for it,” continues Jeff. “The crushed material can be fed directly from the crusher into a wheelbarrow and then utilised as hardcore on the very same job. With the likes of landfill taxes inflating the cost of skip hire, as well as the outlay for buying and transporting aggregate, it makes good business sense. In fact, I’m talking to a housebuilder who’s interested in buying a crusher, and he reckons he can make his money back on the price of a machine on just one of his developments. If tradesmen want to score points with their clients in terms of their carbon footprint, and keep their

customers’ neighbours happy into the bargain, then reducing deliveries to site is also a winner.” The 300mm wide, 180mm deep jaw is designed to be fed by hand, but can also be supplied with material from a mini digger, where its Hardox 400 steel, and unique (patent-pending) crushing mechanism, will then process up to six tonnes of concrete, brick or roof tile in an hour. It can be set to produce three different sizes of hardcore, and, with an overall weight of just 750kg, can be transported on the back of a mediumsized van, pick up or trailer. The CR300 is powered by a 14hp, Briggs & Stratton Vanguard 400 petrol

engine. In a dusty crushing environment that powertrain benefits from the protection of its own cyclonic air filter, as well that manufacturer’s patented TransportGuard system. Here, the throttle lever is also the fuel off and engine kill in one, a function that prevents a common problem with machinery powered with some engines of this spec. Hire companies in particular have reported that it has become common for an operator to shut an engine down, but neglect to turn the fuel off. When the unit is being transported from site to site, the float bowl in the carburettor pumps fuel into the engine, which then dilutes the oil, ultimately resulting in rapid engine wear. “The machine was officially launched at the Saltex exhibition in October 2019, and we’ve since had interest from attending the likes of the Executive Hire Show, where we’ve been a feature on the Briggs & Stratton stand. We’ve also established a dealership in Ireland as well, so things are definitely happening. We’re making the units ourselves, sourcing components as locally as we can, which is important, because it gives us complete ownership of the production process, which guarantees quality.” Indeed, with interest from both hirers and contractors alike, Jeff is now hoping that this really will be the year of the Dragon.

BLACK SPOT & ALGAE REMOVER

A new stain removal treatment will restore the appearance of natural stone, concrete, brick and porcelain. Black Spot & Algae Remover from LTP can break down residue in just two hours, and is suitable for the deep cleaning of new and existing paths, patios and driveways. It targets black spot, lichen, moss, algae, and others stains, caused by damp and slippery leaf matter. FOR MORE INFO VISIT: WWW.RDR.LINK/BP061

COMPOSITE DECKING

Unlike its wood counterpart, composite decking, such as the Piranha range from the Talasey Group, will not rot, warp or split. There’s also no need to stain or paint a deck every year – just simple, regular cleaning. The same company’s Hunter range consists of three colour options, with a wood-effect pattern on one side and a colour-matching traditional grooved finish on the reverse, meaning they can be laid either way or contrasted to create unique designs. Similarly, Fuzion is dual-sided to reveal different shades of the same colour palette. FOR MORE INFO VISIT: WWW.RDR.LINK/BP062

TARPAULIN

100 per cent recyclable, tear proof, chemical resistant, and with a five-year guarantee. That’s what Bio Green is promising for its new Rainexo tarpaulin. Conventional tarps are made from woven material and the waterproofing is sprayed on. Over time, use and storage the waterproofing breaks down, particularly along crease lines. By contrast, this Swissmade and patented composite material is produced using a cross laminated process, with a waterproof membrane sandwiched between the top and bottom layers.

PLANCOFIX LINE in the shower area

t is often difficult to implement walkin shower areas in older buildings, or bathrooms which have an existing shower featuring a raised shower tray. The shower waste water often cannot be drained via a free gradient because the existing waste water pipe in the building sits too high. Even the flattest floor drains cannot override physics, so plumbers need to be creative with their shower drainage solutions.

The high tray of the existing shower ensures the necessary drainage gradient for the waste water

One option is Pentair Jung Pumpenâ&#x20AC;&#x2122;s floor drainage pump Plancofix, a German innovation that was developed especially for this application. It is a flat floor drain with an integrated pump. After the old shower tray, tiles and screed have been removed, it is integrated into the new shower floor and can be tiled as well. As soon as the water runs from the shower into the container, the small pump inside transports it via a pressure pipe to the next sewage pipe. It has been designed to pump up to 30 litres per minute (depending on the model) making it suitable for the use of shower fittings with high flow rates. A sound-insulated tank, together with rubber-mounted Plancofix Line: The motor technology, water channels lead the makes the device shower waste water quiet (< 30 dBA). It into the pump housing. meets all safety standards (has VDE certification) and can be driven over with a wheelchair. There is also a sealing fleece, applied at the factory, which meets the DIN 18534 safety standard.

ON THE LEVEL Pentair Jung Pumpen explains how its Plancofix floor drainage pump can help installers create a walk-in shower in an existing bathroom.

A new bathroom with a walk-in shower: the shower floor is now lower than the waste pipe in the wall and the Plancofix pumps the water upwards into it

Flexible installation

The Plancofix can also be installed outside the shower area if required. For example, if the homeowner would like certain shower drains or trays for design reasons. In this case, the floor drainage pump is connected to the selected shower drain and can be installed inconspicuously â&#x20AC;&#x201C; such as underneath bathroom furniture. Do ensure that accessibility for cleaning and maintenance purposes is taken into account.

The options

The Plancofix Plus with its 9cm installation height is flatter and quieter (< 30 dBA) than the more powerful Plancofix, which has a 10.5cm height. Due to its special sound insulation it is particularly suitable for apartment buildings, hotels or retirement homes. A single point drainage can be achieved with both solutions, while the latest variant, the Plancofix Line, accommodates line drainage.

Line up

The Plancofix Line has integrated channels that lead the shower water into the pump housing. They can be shortened individually and allow a shower width of 1.2m. With this variant, the tiler only has to create a one-sided slope towards the channels. This also results in a more harmonious tile appearance.

GETTING THE HANG OF IT vercoming size restraints in the bathroom is a growing challenge for builders, with the average new build home smaller than ever – in fact, the average size of today’s bathroom now stands at just 4.4 metres squared. With the bathroom the most popular place of refuge in the home, builders are increasingly faced with the task of creating a well-designed, yet functional, space. Our homes are now the smallest they’ve ever been. The average new build house is now the same size as a tube carriage – that’s just 46 square metres. Yet recent research carried out by Geberit found that, despite shrinking spaces in the home, bathrooms are more cherished than ever and the most popular room to escape to from today’s ‘always on’ culture. So, how can builders come up with a bathroom that offers their customers this attractive ‘sanctuary’ whilst still utilising the available space effectively?

Innovations in wall-hung

Manufacturers are recognising this limited space as an issue, and have been developing innovative solutions that tackle the issue of space without compromising on design. As a result, wallhung toilets with concealed cisterns and pre-wall frames are becoming an increasingly popular choice for builders. Going for a wall-hung toilet will instantly create more space – concealing the cistern and lifting the toilet’s footprint off the floor can make even the smallest bathroom appear bigger. For more awkward spaces, meanwhile, a pre-wall frame will enable toilets to be easily installed in a variety of situations including

under a window, in a narrow wall duct or under a sloping ceiling. As well as the obvious space benefits, a wall-hung toilet instantly offers a sleeker and more streamlined appearance than a close-coupled toilet, enhancing the look of the room.

Easy installation

Wall-hung systems have, in the past, often gone hand-in-hand with difficult installation processes, but product innovations such as Geberit’s Duofix frame now mean this is no longer the case. Designed for simple, efficient installation and with ease of maintenance in mind, systems like Duofix eliminate the complex fitting process previously associated with wall-hung systems. With the cistern concealed inside a drywall, additional studding isn’t necessary. Cleverly concealed fixings and the easily positioned water inlets make installation much simpler. Access to the cistern is via the flush plate, allowing for simple servicing when required.

Cost-efficient style

For many years, the perception of wallhung systems has also been associated with a hefty price tag – however, with these systems now more readily available

across the market, they’re more affordable than ever. For those in the trade, it’s worth acknowledging some of the advantages that opting for wall-hung can have on your own business success. The installation efficiencies, for example, will save time – and the added benefit of introducing your customers to style-led choices that maximise their space will do your reputation no harm. Despite the quicker, simplified installation process, specifying a wall-hung toilet using these systems is still a clear upsell opportunity compared to a floor-mounted alternative. Some additional specialist labour costs are maintained, without blowing the budget. Hygiene and ease of maintenance is another important consideration and selling-point for your customers. With the toilet lifted off the floor, cleaning is made even easier with no hard-to-reach areas. This is another clear benefit in comparison with close-coupled alternatives, leaving nowhere for dust and dirt to accumulate.

Going wall-hung?

When faced with a bathroom project that throws up challenging space and size constraints, wall-hung can overcome these issues. Considering ease of installation, the flexibility of the design options, and the ability to offer style-led choices to your customers after that stylish sanctuary in their home, going wall-hung is a no-brainer for builders and customers. The growing availability of these systems offer builders a very simple opportunity to execute an innovative design that could boost your bottom line and overcome the ever-growing challenge of shrinking space in the home.

THE BRIT AWARDS! or years plumbers have used wooden noggins for fixing pipework in floors and stud walls. Whilst this is a tried and tested method of installation, it is not always the easiest or most convenient method: it can be time consuming to find pieces of wood, cut them to size and fix them in place, then line up the clips in longer pipe runs. Walraven has just launched a shorter version of the popular Britclips RSWB (Rapid Sliding Wall Bracket) for gaps of 10-16″ (25-40cm) – designed for fixing pipes in floor joists and non-standard stud wall divides. Many plumbers have been using the standard length RSWB, and cutting it down to fit smaller spaces. After receiving this feedback, the company decided to make life easier for them and manufacture a shorter bracket. Professional Builder asked Walraven to demonstrate how it’s done!

Fitting pipework can be a time intensive process. Walraven explains how to install pipework faster with its Britclips RSWB system.

Last November Aqualisa launched a ‘trade-only’ range of showers, its AQ Collection. Professional Builder speaks with the company’s Colin Sinclair, Senior Channel Marketing Manager, to find out the reasons behind this move, and some of the benefits of the new range.

JOIN THE Q! Q

Why has the company launched a ‘trade-only’ range of showers?

Aqualisa’s product strategy has always been based on a clear understanding of customer needs, in particular the installer community that has always been integral to the success of our business. The new AQ mixer range has been developed specifically for the trade counter where we believe consistent, pricing and ex-stock availability are key drivers for installers. This is a very competitive product sector but the Aqualisa name has an undeniable reputation for quality and reliability and this range will stand out from the crowd in terms of value for money. We recognise the benefit of developing products with strong installation benefits, so this collection not only has aesthetic value but also integral features that make it easy to locate and fit.

What are the main features of the new AQ Collection? Are there any features that make life

easier for plumbers during installation?

The company has always been associated with performance quality and design innovation. That is again well demonstrated with the new AQ Collection. Safe temperature control and the five year parts and labour guarantee are also important features that apply to the whole range. Solidly built with metal handles, the round and square bar valves come as single or dual outlet showers with separate flow and temperature controls. Dual outlet models have an integral diverter that switches from an adjustable handset to 200mm drencher head, suitable solely for high-pressure water systems. The square bar valve dual outlet has a unique telescopic shower column designed for a more flexible installation process. The single lever valve is a solid onepiece brass body that is suitable for all UK water systems, with adjustable valve inlet

pipe centres for easy fitting as either new or a replacement. The brass dual lever valve, again made for all plumbing systems, is supplied as an exposed or concealed fitting in one box meaning the installer has a choice depending on style preference and pipework. Adjustable fixing points for the shower rail make installation even easier.

What designs options are available in the AQ range? Are there both concealed and exposed options? The new extended range based on the series includes the popular 75 and 150 round bar valve models, a modern square bar valve, a compact single lever control valve and a stylish dual control valve, that can be fitted as either an exposed or concealed unit. The modern AQ Collection, all in polished chrome, now offers more choice of looks and style to fulﬁl individual design preferences and also, of course, is still the same easy and ﬂexible installation that it’s always been. The range selection covers all approved UK water systems. As the modern consumer is looking for a custom design to match their personal preferences, so the Collection provides a selection of valve styles and shower heads with the guarantee of quality and reliability as standard throughout the range.

70 APRIL 2020 PROFESSIONAL BUILDER

Do any of the showers have added safety features?

Will there be enhancements to this range in the near future?

The square bar valve is cool touch for added safety. The products also offer precise temperature control to protect vulnerable users such as children and the elderly from the risk of scalding. The maximum and minimum temperatures can be pre-set by the installer so families can be certain of safe showering.

The Collection will be further supported in 2020 with performance upgrades and added value features that appeal to both installers and homeowners. We are always committed to developing products that meet market needs and dedicated to listening to installer feedback on our products and services. The re-launched Aqualisa Installer Club, now with well over 1,000 members, has become the perfect sounding board for what installers really want.

W Heating and Plumbing Engineers is a loyal customer to Wunda Group and have been servicing the South Wales area for more than 20 years. A supplier and installer of commercial and domestic heating and plumbing systems, Managing Director Patrick Whitehouse reveals why when it comes to underfloor heating he won’t go anywhere else. After starting in the trade aged 16 as an apprentice, Patrick now runs his own business in gas plumbing and heating. PW has used Wunda as its supplier of underfloor heating for around 10 years. “I find the technical side is very good and if you pick up the phone someone is always there to give you an answer and, of course, the products are good quality,” says Patrick, “and I think the most important thing for everybody in the trade

The next day delivery is an added bonus.” “I found out about Wunda through doing a lot of work in the area, speaking with a friend who had used them and

after speaking with a local installer. I was then led to more people who use Wunda, including a very close friend who is also a heating engineer. There is also lots of positive feedback on a few industry Facebook pages and they are one of the bigger players in the industry.” He continued: “Over the years, we’ve installed underfloor heating from scratch in new builds and renovations and we’ve used Wunda’s overlay system, and pretty much every product they supply, as it’s simple to fit and is always evolving. I have found that the overlay system is really popular at the moment, as it is ideal for conservatories and newer houses where people are looking to take their radiators out and put underfloor heating in without too much disruption. There have always been reservations with underfloor heating as people are concerned about how much mess it creates, or that it’s going to be too expensive to fit because you have to dig the floors up, but you don’t need to worry about any of that with Wundatherm and that’s why it is a really good alternative to radiators.”

072_PB_APR20_Layout 1 06/03/2020 12:08 Page 73

But it isn’t just the product that Patrick likes. “Wunda provides a really good service, including support on a Saturday, which many of the big players don’t.” He says: “If there is a problem on a Friday night, or a Saturday morning, then with many underfloor heating companies there is no help available, but Wunda cares a lot about the customer service side, and when I phone in I get to speak to the same people, and get a dedicated account manager, and that matters to me when I’ve got to place an order.” “When placing an order, plans and drawings are provided and I never have a problem if I stick to the diagram, especially as the drawings are so detailed. I wouldn’t swap to another supplier now. Lots of people in the industry like to try out new products but when I find a good product that is always developing I don’t need to go anywhere else.” The company’s new Rapid Response Wundatherm system is, according to its makers, easy to install and durable, with no mess or drying time. The lightweight low profile boards are just 16 or 20mm thick, heat up in minutes and are suitable for any floor finish, including carpet, vinyl, Karndean, Amtico, laminate, wood, ceramic and stone tiles. Once installed, floor heating pipe is laid into the pre-formed grooves in the boards, and the system is ready for immediate use. The manufacturer provides free technical support six days a week, and a specialist service of detailed layout plans for all bespoke systems free of charge to trade customers. With these layout plans to hand, tradesmen can have complete confidence in laying the boards and installing the system.

HAVING AN IMPACT Even the most basic construction task often involves a drill, whether it’s fitting a shelf or hanging a door. Many in the trade are happy to use a drill driver, but could still benefit from investing in an impact driver. Unlike standard drills, impact drivers deliver rotational and linear blows that either drive or loosen screws, while also forcing the bit into the screw head for improved grip. In practice, this means that using an impact driver can render certain tasks, such as drilling pilot holes, unnecessary. However, to get the most from these tools it’s important to understand their power and how that affects the tool’s bits.

Tough Torque

Standard screwdriver bits are unable to deal with the torque exerted by impact drivers and will become damaged if used. In turn, this means that the bits will need to be replaced frequently, which delays works and adds to project costs. Instead, tradespeople should look to use torsion impact bits, which provide much greater durability. Makita offers a number of solutions specially designed to overcome this issue. One example is our Impact Black range, which is suitable for use across a number of tools, fits and applications. Products from the range are on average 20 per cent more durable than a standard screwdriver bit and can easily withstand the high torque produced by impact drivers. The Impact Black range is the perfect solution for anyone who periodically uses an impact driver.

In the latest instalment of our Tech Talk series, Kevin Brannigan, Marketing Manager at Makita, details the company’s new range of Impact Gold Torsion and Impact Black impact bits. However, for those tradespeople who frequently rely on the tool, such as professional landscapers, it’s often best to look for an even more durable solution. Thankfully, this does exist in the form of our Impact Gold

products from the Impact Gold Torsion range can last up to 10x longer with double torsion bits reaching up to 12x longer. This can be further increased to 15x longer when the range is coupled with an Impact Gold Torsion Bit Holder. Unlike standard screwdriver bits the range features a unique design which focuses the forces exerted on a regular screw bit away from the tip. For users this means that there’s far less chance of breakages, even during extreme impact applications.

THE DAILY GRIND!

Professional Builder’s Tibby Singh Chodha gets to grips with the Festool Cordless Angle Grinder AGC 18-125 I am a big fan of cordless tools, and they are definitely the way forward, particularly from a health and safety perspective. The majority of the time, however, I’ve been using an 110V angle grinder but, as we all know, lifting the transformer in and out of the van is a workout alone. I was, therefore, excited to take the Festool Cordless Angle Grinder for a spin to see whether it would last. One thing that will certainly extend its longevity is the dust resistant enclosed motor and electronics. Usually on electric angle grinders there’s no speed control, but Festool are at the top of the game and have a speed control from 1 – 6. This means the speed can be adjusted from 4,500 – 8,500 rpm, making it suited to various discs and numerous surfaces. It’s more efficient and, thanks to a fixed high speed, can even prevent you from burning the surface. The Festool is relatively quiet for an angle grinder, although I do wear my ear defenders, which I would always recommend. There’s also surprisingly little vibration and, once you have the appropriate gloves on, you won’t feel a thing. One of the reasons for this is that the motor isn’t in contact with the body. The outer body feels very comfortable to handle thanks to its ergonomics. It also comes with a Vibrastop handle, which dampens the vibration, and additionally has the option to be placed on the right or left hand side.

In a spin

A pet hate of mine when using grinders is the blade spinning for a while after you’ve switched it off. This means you have to waste time waiting and being extra careful when placing it down onto the surface. You don’t have to worry about this with this Festool Cordless Angle Grinder as it has a motor brake. In other words, it will stop dead literally within seconds after switching it off. It does have a soft start, which you’d expect in almost every power tool these days, but what I wasn’t expecting was an electronic overload protection. If the machine is being abused, it will automatically cut off, saving it from burning out. With all the excitement I almost forgot to mention how quick and easy it is to change the cutting discs. Going back to normal grinders you would usually need the key to tighten the flange nut, but not with the Festool keyless flange. Of course the disc can tighten itself when in use, so it still comes with a key to loosen it just in

case. It has a standard M14 thread, so it’s completely compatible with attachments with threads, such as wire brush attachments. The guard can also be easily turned and locked into position by the push of a button. As I was working I actually forgot to put the other battery on charge, so when the battery I was using went flat it gave me an excuse to have a break. It was only a quick tea break because the Festool 5,2 Ah Li-ion 18V AIRSTREAM battery was ready to go in no time. This new AIRSTREAM technology makes it three times faster to charge. I had no excuse for both batteries to go flat as they have an LED battery level indicator, which lets you know the remaining capacity with the push of a button.

OFF TO A PLIER! Chris Burdett gets his hands on a selection of Knipex tools and gives his verdict for Professional Builder. This PLIERS WRENCH is a new version in an already popular range, but has a slimmer 180mm length. It has narrow gripping jaws which are good for getting into confined spaces for hard to reach tightening jobs. Knipex says it has considerably reduced the weight of these pliers by around 10 per cent and they feel really good in the hand. The jaws are very smooth, which means you can work directly on chrome without leaving any marks or damage, essential in these lovely bathrooms we fit! Of course a major feature on the pliers is the gripping mechanism. You just push

the button and it grips nicely without slipping. It’s a great all rounder for plumbing and heating work. A more traditional shaped tool, the ELECTRONIC SUPER KNIPS are ultraslim cutters with very sharp edges, with shaped tips. It means you can use them for very fine wire cutting work but also for shortening cable ties so they are flush. These Knips are very light and are VDE tested, so they are going to keep you safe too.

The ERGOSTRIP looks like no other tool I have ever seen, and my sparky was really impressed with it. It is a small tool that allows you to strip and dismantle all cables used in houses. Being so small it is ideal for use in confined spaces, such as junction and distribution boxes. We used it in the loft cavity we were laying cable

GOT IT IN YOUR POCKET Professional Builder charts the rise of the pocket door

In the past it would be fair to say that pocket doors could be problematic, both for the end user and installer. How has that changed? The pocket door market has traditionally been dominated by a low cost wooden based system designed in the 1950s that could be unreliable due to warping and was a hassle to fit. The arrival of the steel pocket system a few years ago was hailed as a game changer, but it was quite expensive and not within everyone’s pocket (ha ha). The steel systems proved to be more reliable and easier to fit, as well as having a better sliding action and extended lifetime.

need to be assembled, but this is a very easy process that can literally take you no more than 20 minutes, and you have the full sliding system ready to install – all you need is a power screwdriver. For the installation, a drill a screwdriver and a level is just about it. The Rocket system uses standard 12.5mm plasterboard, standard 35 or 44mm UK size doors, and finishes to standard wall thicknesses, so there’s nothing special or difficult about the installation.

Yes, but why have pocket doors become so popular in the last few years? Well, it’s all down to costs really, especially with the arrival of the all steel ‘Rocket Pocket’ system nearly three years ago. It promised a steel pocket system at the same price as the wooden ones, bringing a more reliable and longer lasting pocket to everyone. Rocket Pocket is a full steel pocket door system for everyone’s pocket.

How did Rocket Pocket manage this? Improvements in the manufacturing, using cold rolling of steel, meant the complete system could be manufactured more efficiently – and much more economically. Rocket Pocket steel systems are designed specifically for use with UK standard doors, either 35 or 44mm, so you can purchase the door of your choice and it fits into the Rocket system.

Are Rocket Pocket Doors easy to fit? Firstly, you can choose your own UK standard door panel. The system does

So, why should I buy a Rocket Pocket system rather than a competitor? Lots of reasons, and cost is the first, as well as next working day delivery included in the price. What you’ll be getting is a full steel pocket system at less than the cost of many wooden systems. Add to that, strength, reliability and top class customer service and it’s as good as it gets.

Do Rocket just make Pocket Systems? Actually they are at the forefront of the development of flush hinged door systems, which are becoming very popular at the moment – no jambs, no architraves, with the door flush with the wall. TAKE A LOOK AT THE ROCKET DOOR FRAMES WEBSITE AT: WWW.RDR.LINK/BP102

ROOFING

TAKE IT AS RED Jenni Forrest, quality manager for JB Red at Marley, explains how to cut timber waste and choose sustainable roofing battens

rowing consumer and political pressure to take action on climate change means sustainability is an increasingly important issue for builders – from reducing the environmental impact of materials, to cutting waste and increasing recycling on site. Timber is recognised as being one of the most sustainable building materials, providing it is sourced responsibly from

well managed forests. However, there is still a high degree of timber waste generated on some construction sites and not all timber offers the same levels of quality and sustainability. So, when it comes to timber roofing battens, how can you be certain you are making sustainable choices? There are a number of things to look out for: ● PEFC or FSC certification Any roofing battens you use should have either FSC or PEFC certification listed on the documentation. This proves the timber is sourced sustainably, from well managed forests with excellent replanting programmes. All of our roofing battens carry either FSC or PEFC certification. ● Third party accreditation To comply with BS 5534, all roofing battens should be stamped to demonstrate compliance with the British Standard. However, there are concerns that not all battens stamped as BS 5534 compliant actually meet the grading standards. For peace of mind you should also check for third

86 APRIL 2020 PROFESSIONAL BUILDER

party assurance of batten quality and sustainability. Our JB Red battens are covered by a BBA Agrément certificate and are stamped to prove that not only are they compliant with BS 5534, but also that they are responsibly sourced with high manufacturing standards. ● Manufacturer recycling If you want further proof, check the manufacturer’s own recycling practices. One of the benefits of our manufacturing process is that we don’t waste any of the timber and none of it is sent to landfill. All timber that is left over from manufacture, whether off cuts, chippings or shavings, is used to manufacture a number of products including chipboard, wood pellets, animal bedding and biomass wood chip. Although timber is a sustainable material, it is still important to minimise waste where possible and make sure it is recycled, rather than being sent to landfill. As well as reducing your environmental impact, this will also cut the cost of materials and disposal.

086_PB_APR20_Layout 1 06/03/2020 14:52 Page 87

TECHNICAL TEAM TIPS – NO 15

There are several ways to minimise timber waste on site: ● Buy quality battens from a trusted manufacturer Buying a quality roofing batten will save a significant amount of waste. Our JB Red battens are manufactured using kiln dried, side-board timber which gives a straighter, stronger batten. All our battens are machine graded with the state-of-the-art Goldeneye laser scanner. This minimises waste because all battens are compliant and suitable for use. An inferior batten can contain noncompliant defects, which leads to more waste on site during the fixing process. Our battens are also delivered with minimal packaging, so there is little waste for contractors to dispose of on site. ● Order the right amount of batten, in the right length, for the project When installing roof battens to comply

with BS8000-6, the joints should be staggered up the length of the rafter, so it is advisable to purchase a variety of different lengths to minimise cutting and waste. JB Red battens are available in a number of lengths to suit your project, minimising the amount of cutting that you need to do. Your merchant should have a selection of different length battens for you to choose from. From minimum 3.6m to maximum 5.4m, increasing in 0.3m increments. Get a new specification for every project and plan the roof layout in advance to make sure you are ordering the right amount of batten. YOU CAN VIEW THE FREE MARLEY SPECIFICATION TOOL AT: WWW.RDR.LINK/BP125

● Store battens properly If you aren’t using battens immediately, store them securely to avoid wasting product. Store battens and counter battens on sufficient bearers to prevent sagging or twisting. Battens should also be protected from the elements whilst still maintaining air flow around the timber. ● Set up re-use or recycling areas If timber battens need to be cut to length on site, then set up a recycling or re-use area to ensure any waste is being disposed of sustainably.

Whatever the reason, sooner or later, the day will come when you have to sell your van. Honest John Vans has put together some useful tips to ensuring a straightforward sale and getting the best price for your used commercial vehicle, whether trading-in or selling privately.

Sometimes the old ways are best. If you work on a large or busy building site, a sign in the window may prove to be the quickest and cheapest method for selling your van (it’s free, after all). Be sure to include your contact number, price of the van and information about the MoT and mileage. If you choose to sell your van with a sign in the window, it’s wise to prepare Dealing with road tax Remember, it’s no longer possible to sell a van with road tax (also called Vehicle Excise Duty). This means you need to cancel the tax and get a refund for any full calendar months remaining when you sell the vehicle. The DVLA will send a refund or cancel the Direct Debit, if you pay monthly. The new owner will then need to tax the vehicle in their own name.

the van for sale. Consider paying for any small repairs that may have been on your ‘to do’ list for some time as this will help maintain the price. It is also worth renewing the MoT, if it has less than six months remaining, as a full test certificate will always make the vehicle more desirable compared to those without.

Part-exchange

A part-exchange can be a quick and easy option, if you’re planning to buy a new van from a dealership. But it’s vital that you understand the overall cost. For example, a dealer selling a new van at £25,000 may offer £5,000 for the partexchange and no discount on the new van, which means the overall cost is £20,000. Another dealer with a similar van may offer a £2,000 discount and a £4,000 part-exchange, which means the overall cost is cheaper at £19,000, despite the fact its trade-in value is less. Be very well aware of what your existing van is worth. Compare it with similar models of similar age and mileage, which the dealer has up for sale, and don’t accept less than £1,500 or 15 per cent (whichever is the greater) less than the sticker price on these vans.

Selling a van on eBay

eBay is a great place to sell a van, with over 30,000 listings for commercial vehicles. The most important thing is to

decide how you want to sell. Sticking with a conventional classified ad is the safest option, but you may wish to put it to auction instead. This can include a ‘Buy It Now’ option and a reserve, so you can protect yourself from the vehicle selling at too low a price. eBay makes most of its money by taking a slice of the final selling price rather than demanding a large fee up front. This is called the Final Value Fee, and for other goods it is 10 per cent of the item’s final selling price. Happily this is reduced for vehicles, so you pay one per cent of the final value, with a minimum of £25 and a maximum of £45.

Online van buying services

Online van buying services have increased in popularity in recent years, by offering a simple sale route and the promise of a fast transfer of funds. There are lots of companies vying for your van and the process is relatively simple too, with the buyer’s website asking you to type in the registration number of the vehicle and some details of its condition. You then take it to one of the company’s centres to complete the sale. However, while online buying services are useful for owners who want a fast and simple sale, they tend have a reputation for offering the lower prices. This means you’ll probably get a price that’s much lower compared to selling the van privately.

House rules

When S&R Construction took the strategic decision to move from renting equipment to running its own machines, the contractor turned to Takeuchi. Professional Builder’s Lee Jones talks to the company about a major investment in the compact plant specialist’s kit.

hilst many SME contractors are content to continue renting the equipment they require, there is often a compelling commercial argument for owning a fleet of machines. Following a period of considerable expansion, multi-utility installation provider, S&R Construction made just that calculation. “It just didn’t make financial sense for us to carry on hiring, and we had previous experience of using Takeuchi diggers from a rental firm who were already supplying us with excavators,” explains Accounts Manager, Charlie Craig. Thanks to a full order book of housebuilder customers, the company was in a position to invest in equipment, and it was S&R Construction’s experienced operators who pointed to the Japanese manufacturer. As a result, the west midlands building firm’s fleet now extends to a nine tonne TB290, three TB250s, and six TB216s. “The main attraction for us is the power, because these are machines that will be doing a considerable amount of trenching,” continues Charlie. The Dudleybased company specialises in installing

the utilities for housebuilders, and currently has 14 live sites around the country with developer, Countryside alone. “We’re digging step trenches for water, gas and electric, as well as the necessary BT and Virgin infrastructure,” adds the company’s Gareth Tennant. “The 9 tonne TB290 has proved to be an absolute beast and we recently dug 65metres – 2m wide, 750mm deep – in just three hours on a site in Leicester. There’s also very little that can go wrong on them. A top mounted hydraulic boom cylinder and internally routed hoses, on the 1.6 tonne TB216 avoids on site damage, for instance.” Utility jobs can be tough on machines, with some sites demanding kilometres of trenches to be dug. Regardless of the weight class, Takeuchi’s units have proven to combine strength with agility, and that is equally true of the TB216, also on the same Leicester site.

Manoeuvrability is enhanced with retractable and extendable tracks, making standard doorways and gates accessible, whilst equally allowing an expansion of the machine’s footprint for greater stability. Maximum digging depth on this 1.6 tonne machine is 2,390mm and maximum reach at ground level is 4,035mm.

Into the Swing

Housebuilding sites, particularly on more compact plots, demand manoeuvrability and, with a shorter than average tail swing compared to a conventional 9tonne excavator, that’s just what the TB290 provides. Thanks to improved visibility, a 1,650mm tail swing radius, and rounded corners operators should be able to avoid damage in even the tightest spots. Not only that, but efficient finishing and grading is facilitated by a 500mm high, heavy duty dozer. Takeuchi’s 9

090_PB_APR20_Layout 1 06/03/2020 11:16 Page 91

vehicles & plant 씱 tonne unit promises what the manufacturer describes as significantly more breakout force compared to its existing TB285 and TB175 models. The standard long arm provides a ground level reach of 7,290mm and digging depth of 4,580mm. Dual boom cylinders with hose burst check valve provide added lifting power, and additional clearance for bucket and attachments. When S&R were in the market for new equipment one other major consideration was security, and again this Japanese manufacturer’s Takeuchi Security System (TSS) scored highly. As a result, machine owners can be reassured that only programmed keys will start the machine, and the attempted use of anything but the correct key will generate an alert.

“Housebuilding sites, particularly on more compact plots, demand manoeuvrability and, with a shorter than average tail swing compared to a conventional 9-tonne excavator, that’s just what the TB290 provides.” CanTrack Security Feature

Not only that, but Takeuchi Dealer Bow Plant Sales has installed the latest in CanTrack technology prior to delivery. “We’ve previously had a mini excavator from a different manufacturer and, having only been in possession of it for a two week period, it was stolen from an apparently secure site, so it’s something we were very sensitive to,” Charlie adds. “An investment of upwards of ½ million is considerable for a company like S&R,” explains Zac Clulow of Bow Plant Sales. “We’ve made sure that they’ve been rewarded with the best equipment that their money can source, including MARTIN excavator buckets and Hill Engineering Tefra hitches, which are renowned for their durability over extended use.”

Becoming a multi-utility provider is far from a straight-forward procedure and the family run firm, spent a solid 18 months ensuring that it had the necessary accreditation, including inclusion on the Lloyds Register, a body which independently assesses the competency of contractors in the sector. “It was five years ago that we made the decision to focus on utilities and the growth has since been meteoric,” continues Charlie. “Because we can install all the necessary utilities in one trench, we’re a one stop shop for the housebuilder, who might otherwise have to individually recruit a water, electric and gas company for the installation. If there’s road closures necessary for each of these, S&R’s one trench can avoid a considerable amount of disruption. That means that the trenches we are digging are larger and deeper, which is why the Takeuchi machines are invaluable. We’ve also ensured that they are ready for any site by over over-specifying on health and safety, for example, with green seat belt beacons and a reversing camera on the larger units.” FOR FURTHER INFORMATION ON THE RANGE OF COMPACT MINI EXCAVATORS FROM TAKEUCHI VISIT: WWW.RDR.LINK/BP104 IF YOU’RE LOOKING FOR A PROFESSIONAL UTILITY INFRASTRUCTURE PROVIDER VISIT THE S&R CONSTRUCTION WEBSITE AT: WWW.RDR.LINK/BP105

Taking it to the maxus! New models and a new consolidated brand image – the MAXUS will also pioneer some of the most advanced powertrain technology.

t’s fair to say that it has found itself in more than a few cul de sacs these past thirty years, but the open road now beckons for one of our best known vehicle brands. From this month the iconic former West Midlands LDV moniker will disappear completely to become MAXUS, and fall in line with the global aspirations of its parent company, China’s largest automotive manufacturer SAIC. The rebrand coincides with the launch of two new models, the Deliver 9 and all electric E Deliver 3 that will underpin the

transformation from light commercial vehicle challenger to what the company believe will see MAXUS emerge as a leading premium mainstream brand throughout Europe – one that will deliver on spec, quality, technology and price. Since 2015, the distribution rights for right hand drive in Europe has been with the highly experienced, Eire-based Harris Group, which is firmly behind the new consolidation programme. “The next twelve months is going to be the brand’s biggest year, with the impending launch

of our game-changing diesel panel van and the arrival of a second EV model, which will make MAXUS synonymous with electric commercial driving”, enthuses Mike Barret general manager of MAXUS UK adding: “SAIC has shown its commitment to the development of viable alternative powertrain technology with a recent investment of almost three quarters of a million euros and the market can look forward to many more ground breaking innovations over the coming years from this stable.” IF YOU WANT TO DOWNLOAD AN LDV BROCHURE VISIT: WWW.RDR.LINK/BP106

Go buy the board The expert panel sits to examine CaberWood MDF installation single piece of board. A major advantage is the relative ease of finishing perpendicular and moulded edges without the need for elaborate filling or the application of adhesive bonded edging materials. This characteristic derives from its uniform density and the absence of core voids, which would require filling.

CaberWood MDF has a consistent density and a smooth surface that is ideal for machining, profiling, painting, or the application of paper foils and veneers. In many respects, the material can be treated as a high quality timber; without the inherent defects of knots and grains.

Machining

As a homogeneous wood fibre material, it is ideally suited to modern machine tooling. It can be worked easily with all conventional woodworking machines and hand tools; it saws cleanly and drills easily and shapes and routs exceptionally well without splintering or chipping.

Profiling

Profiled edges require no edge banding or lipping. Sculptured or textured effects can be machined or embossed, and narrow or small door frames can be produced from a

Sanding

Sanding after moulding or routing produces a much smoother finish. The moulded edges can be sanded with any number of different profile sanders. Various polyurethane based abrasive wheels are available to fit to spindle moulders or in line with a double end tenoner. These wheels can be shaped to the cutter profile using an abrasive paper glued to the desired edge profile. 80/100 grit should be used for the removal of cutter marks. 120/150 grit is usually used for finish sanding with finer grades available, if required.

Sawing

Saw blades and tools should have increased clearance angles to reduce resin build up and reduce the life between sharpening.

Follow these tips to ensure best results, minimum breakout and a longer tool life: ● Tungsten carbide saws are recommended for general use ● Saw blades should have higher clearance angles and increased tool angles compared with normal woodworking saws ● Clearance angles should be maintained when the saw is serviced. Reduced angles will increase the amount of resin build up. Increased angles will reduce the life between sharpening ● Chipload – which is the thickness of chip cut by each tooth – should be in the range of 0.15 to 0.25mm. The feed rate required to produce this is calculated as follows: Feed rate (mm/min) = Chipload x r.p.m. x no. of teeth FOR MORE INFORMATION ON CABERWOOD MDF VISIT: WWW.RDR.LINK/BP107 NORBORD HAS PRODUCED A WHOLE RANGE OF VIDEO GUIDES FOR ITS PRODUCTS.

ADE’S TOP WINDOW & DOOR TIPS

No. 15

! ’ L L A ‘C S ’ N A I R D A

Adrian Barraclough runs Quickslide, one of Britain’s leading window & door manufacturers.

THINGS ARE LOOKING UP! This month, Ade goes through the roof with the latest in overhead glazing

A significant change in recent years has been the broadening of demand for overhead glazing solutions. Where once all that was generally available were the ubiquitous tilting roof lights that are ideal for sloping roofs, now the market is awash with overhead glazing panels of every size and shape and everything in between, which are ideal for flat roofs. One of the key drivers for this is the revolution that has taken place in the conservatory sector: the basic lean-to, Edwardian and Victorian styles of conservatories have been replaced by more sophisticated structures, not least the ‘Orangery’ which, whilst bearing only a passing resemblance to their country house namesakes, have nonetheless changed the game. Again, influenced by such programmes as Grand Designs, homeowners are now more ambitious in their visions for increasing the living space of their homes, with some fantastic options offered for letting the light into conventional extensions. The leading light (sorry!) in this charge for brighter, airier living spaces are lanterns and roof lights, both fixed glazed solutions that are designed simply to allow in more natural light to brighten up what might otherwise be dark and dingy extensions. The importance of these shouldn’t be underestimated: so many extensions

94 APRIL 2020 PROFESSIONAL BUILDER

have been built to add space, which then becomes under-utilised because they are dark and inhospitable. The addition of roof glazing changes the fundamental nature of an extension, and inexpensively too. A traditional conservatory remains an attractive option because of the ability to add space quickly, inexpensively and often without any requirement for planning approval. But increasing numbers of solid walled and roofed extensions are being built instead as the glazing options – vertical and overhead – blur the lines between these options. It has never been more important to understand just what options are available when helping a homeowner to decide on their new extension. When they come to you excited about installing bi folding doors or sliding doors, make sure they understand that adding

rooflights is also important in order to ensure light is spread evenly throughout the structure, thus preventing shadowy corners. And if you’re building a raised

patio or deck area, consider glass balustrades for uninterrupted views as well. As an example, our rooflight offer is fixed flat units that provide exceptional thermal insulation, light transmission and noise reduction, with the choice of double or triple glazed units. They are supplied in a slim and elegant aluminium frame, which is simplicity itself to install. And, whilst you would hope that rooflights might avoid accidental damage, these allow the glazing unit to be replaced without removing the frame. We also offer a choice of glass and would always recommend self-cleaning, such as Pilkington Activ. Believe me, it’s worth the little extra it costs. The upshot (sorry, there I go again) of all this actually is ‘Glass is Good’; use that as your mantra when talking to your potential customers, commercial or private, include as much glazing as you can in any of your pitches and watch the work come rolling in!

STROKE...

...CONTINUING OUR LOOK AT BLOOD PRESSURE AND HEART HELP, ANGINA IS THIS MONTH’S EXAMINATION

Over the previous columns, the importance of recognising and managing high blood pressure and cholesterol have been discussed. Reducing these can lower the risk of having a stroke. The term ‘stroke’ can cover several different things so what do we really mean by this? A stroke is a term for a serious and sometimes life-threatening condition where the blood supply to parts of the brain is cut off. Inside the brain we have many different blood vessels that supply the different parts of the brain that have different functions.

symptoms starting then treatment might be an option to dissolve the blood clot. If the blood supply can be improved, the brain tissue may not die and the symptoms might improve. Some people will have symptoms of a stroke which then resolve within 24 hours of onset. These are known as Transient Ischaemic Attacks (TIAs). TIAs can be a warning sign that a bigger stroke is going to happen. If a TIA happens then a person should be assessed and investigated for causes that may lead to stroke.

So, what does make you more likely to have a stroke? Having high blood pressure, high cholesterol and diabetes can There are two main types of stroke: all make you more likely to have a stroke. Another condition Ischaemic stroke – this is when a blood clot blocks a blood which is a big risk factor for stroke is called Atrial Fibrillation (AF), vessel in the brain and stops the blood flow (this is the cause in where the heart muscle beats irregularly. This is because these 85 per cent of strokes) Haemorrhagic stroke – this is when there is a bleed from one of conditions cause damage to the blood vessels in the body, contribute to blood vessel narrowing and increase the risk of the blood vessels into the brain tissue. The blood flow is blood clots forming, which can then travel to the brain and cause disrupted as it leaks into the brain. a blockage. When a stroke happens, if there is no blood supply to that Anybody that has a TIA or a stroke will have tests to find out part of the brain then no oxygen is being delivered to that area what the cause might be.

of us surprised? The Grenfell Tower disaster was an accident waiting for its opportunity to happen. I don’t like to say, “I told you so”. Well, I do actually. Especially with regard to this particular subject. Back in the day when I had a building advice column in a national Sunday newspaper, I regularly warned my readers about the potential problems of thermal insulation. Don’t get me wrong, insulation is a wonderful thing. When it is fitted correctly, thermal insulation keeps our homes and offices warm, and saves money on heating bills. Acoustic insulation reduces noise transmission and improves our living environment. But when insulation is fitted incorrectly, it can be worse than useless. It can create dampness and mould, corrosion of wall ties and other metal fixings, and generally make life miserable for the occupants of buildings. And now we know that insulation can catch fire, too. And when it does, it gives off toxic fumes that can kill. Believe it or not, kids, when I first started on site in 1972, there were still buildings being constructed with solid brick walls. And those new-fangled cavity walls didn’t have any insulation in the cavities. I wish now that I’d taken some pictures at the time, because some people don’t believe me. And then we had to start building 25mm polystyrene sheets into the cavities. Wow, that must have made a difference! But there were always worries about it,

because when polystyrene catches fire it gives off poisonous fumes. And firemen hate that material because when polystyrene ceiling tiles (very popular in the 1970s) catch fire, they melt and drip molten globs of burning plastic onto them. As the years went by, that cavity insulation grew to 50mm, then 75mm, then 100mm. And the polystyrene was superseded by foam materials that had better insulation properties. It can all burn, and give off toxic smoke but, hey, it’s enclosed in the cavity so that will never happen. Or so they say. And then external insulation became popular. Same insulating foam, same possibility of burning, only this time enclosed by metal sheets, so that will keep it safe, won’t it? Sadly, the Grenfell disaster showed us otherwise. For a more obvious example of flammable external cladding, you have only to look at architecturally-trendy timber. Yes, that’s right – since the 1990s, architects have been cladding newbuild flats and houses with sheets and planks of unprotected wood. I don’t like to say, “I told you so” (have I said that before?) But I always thought it seemed like a crazy idea. And now it seems that people with timber external timber cladding on their homes are unable to sell them. Well, who ever would have guessed?
