The benefits of warm

succession of surveys that focus on the construction and manufacturing industries have unsurprisingly painted a very stark picture of the first six months of 2020 and offered bleak forecasts for the rest of the year and beyond.

But would you expect anything other than a record contraction for both industries given the global pandemic that has seen work grind to a halt?

As we enter the summer, however, there are cautious signs of optimism and the likes of industry analysts Glenigan point to the re-opening of sites and manufacturing sites as a sign that the project pipeline for constriction is looking healthier than at any point in the first six months of the year.

Meanwhile, the Construction Products Association has developed a series of scenarios to assess the impact of Covid19 on construction output, given that the full effects of the pandemic are so wide ranging and lack precedents.

The most optimistic scenario is based on a ‘V’-shaped recession affecting primarily the second half of March, April and May, followed by a recovery from June at a slower pace than the initial decline. The other scenarios include a W-shaped recession (a second wave of infection and lockdown in 2020 Q4 and subsequent recovery in 2021 Q1) and a U-shaped recession (continued restrictions throughout 2020 and a slow recovery in 2021 as businesses and consumers come out of it highly riskaverse).

The CPA’s Economics Director, Noble Francis, said there were also signs of welcome growth in key sectors. “A more positive outlook is expected for infrastructure activity thanks to a greater ability to implement safe distancing for workers on larger sites but also, vitally, thanks to HS2 being given the go ahead to proceed,” he explained.

“For the fortunes of construction more generally, though, the near-term effect of Covid-19 on the economy and employment are likely to be considerably greater than those faced during the financial crisis of 2008/09.”

The challenges we all face are going to be huge, but they are not unsurmountable and the collaborative approach displayed during recent weeks will go a long way to shaping a positive future for the industry.

Construction optimistic about post-pandemic prospects

More than 90% of construction professionals around the world said they expect their business to survive the COVID-19 pandemic in a survey conducted by the Chartered Institute of Building (CIOB) and its Global Construction Review publication, gauging the financial, operational and personal impact of Covid-19 on the global industry.

Taken by more than 500 construction professionals from Australia, Canada, China, Ireland, Malaysia, Qatar, Saudi Arabia, Singapore, South Africa, United Arab Emirates (UAE), United Kingdom and the USA, 56% of survey respondents said their organisations were keeping all or some sites open. 76% said their employees were able to observe social distancing on their way into work, and 84% said they were able to observe social distancing onsite.

Caroline Gumble, Chief Executive of the CIOB, said: “Firstly, many thanks to everyone who completed our survey. It’s a busy time for most people in our industry so the responses are much appreciated.

“Secondly, it’s good to hear that there is so much activity getting underway and much hope and positivity in the industry. While it was necessary for some sites to temporarily close their doors, we are glad to see that the majority of construction workers are optimistic in their outlook and are able to maintain a safe environment whilst working.

“However, we want to remind everyone that it is imperative to stay safe and follow the appropriate guidelines, including, for the UK, the latest CLC Site Operating Procedures.”

Most respondents worked for larger companies, with nearly half (48.8%) working for companies employing more than 500 people. Of those, 37.3% work for companies employing more than 1,000 people. In terms of employer organisations, most (37.4%) were main contractors. The main types of other employers were project manager/ QS (14.2%), public-sector client (10.9%), consulting engineer (10.4%), private-sector client (9%) and specialist contractor (5.7%).

Among the personal stories from the survey, many CIOB members have been stepping up to ensure that vulnerable people - in construction and in society at large - are protected during this pandemic.

Sites continue to reopen as construction pipeline grows

During May the number of suspended sites has continued to decline, with work restarting on a further 91 sites - 45% of the initially suspended sites have now restarted, according to Glenigan.

Larger sites in particular have been reactivated. As a result, 57% of the value of construction work that was initially suspended, is now underway again.

Site reactivation has been most widespread across the office, health and education sectors. However, at 47%, an above average share of private housing projects have also now restarted. The private housing sector was especially hard hit by the initial suspension of work and developers have been implementing a phased programme of site re-openings. Despite the above average proportion of restarted sites, at just over a third, a greater proportion of private housing sites remain closed than any other sector.

Overall work was suspended on 24% of construction sites, accounting for 22% of work by value. Public non-residential areas such as health, education and community & amenity sectors, and civil engineering all have a smaller than average proportion of suspended sites.

The number and value of project starts have fallen sharply since the lockdown came into force during the second half of March. The Glenigan Index tracks new construction activity by looking at the value of project

starts excluding high value projects of £100 million or more.

The latest Glenigan Index has recorded a 61% fall in the value of project starts during the three months to the end of May against the same period a year ago. The value of starts in May alone was 68% down the level of a year ago.

Within this total civil engineering projects have fared better than residential and non-residential work, with the value of civil projects during the three months to May 42% lower than a year ago.

Looking ahead, Glenigan insists the value of projects starting on site will progressively recover from June as the lockdown is eased.

The number of planning applications being published by planning authorities has averaged 1,478 a day over the last week. This is little changed on the previous week and just 6% lower than the daily average seen earlier this year, prior to the COVID-19 lockdown. At 1,455 the daily average number of published planning decisions was 11% up on the previous week although it remains 7% lower than the average seen prior to the lockdown.

It suggests that the industry has a potentially growing pipeline of planned projects as the lockdown is eased further over the weeks ahead. Now is the time for firms to be proactive in planning their future workloads as the recovery gets underway.

New £1bn building safety fund to remove dangerous cladding from high rise buildings

Building owners have been urged to act and put the safety of residents first as the government’s £1 billion Building Safety Fund to remove dangerous cladding was launched today by Housing Secretary Robert Jenrick MP.

It comes as the government has published the prospectus for the fund which will meet the cost for remediation of unsafe non-ACM cladding systems on residential buildings in the private and social sector that are 18 metres and over and do not comply with building regulations.

This fund is predominately targeted at supporting leaseholders in the private sector facing significant bills. However, the government is clear that for leaseholders living in buildings owned by providers in the social sector, it will provide funding to meet the provider’s costs which would otherwise have been borne by leaseholders. The government expects landlords to cover these costs without increasing rent for their tenants.

The government’ is already providing £600 million for the replacement of ACM cladding systems bringing total funding for remediation up to £1.6 billion.

Ministers have been clear that they expect building owners who are already remediating their buildings should continue to do so. They should explore every opportunity to fund this work before seeking funding from government or passing on costs to their leaseholders.

The fund’s application process has been designed to enable projects to proceed at pace with building owners, freeholders or others responsible for the building urged to register for the fund on Monday as applications can be progressed alongside the development of the remediation project.

It comes as the government has also published an amendment to the statutory guidance to building safety regulations –

RIBA calls for ‘decade of action’ with new report

The Royal Institute of British Architects (RIBA) has published a new report revealing architects’ views on the climate emergency and showcasing exemplar applications of the United Nations Sustainable Development Goals (SDGs).

‘A Decade of Action: RIBA Members and the Sustainable Development Goals’ reveals the profession’s strong commitment to sustainable development and climate action, but also highlights that more progress needs to be made by architects, clients and the UK Government to raise the bar.

In a detailed member survey:

• 66% of participants said their organisation is committed to addressing the climate emergency.

• Project Cost Constraints (79%) and Client Requirements (70%) were cited as the biggest barriers to building sustainably.

• 82% said their organisation believes the UK Government must legislate for higher standards.

• 70% said their organisation would welcome the Building Regulations mandating ‘zero carbon’ by 2030. The second part of the RIBA report showcases best practice examples of how the UN Sustainable Development Goals can be embedded in projects, practices and schools of architecture.

It highlights schools which reference and discuss the SDGs, projects which apply and further the SDGs, and practices which base their entire business strategies on them – from business operations, to supply chains, to practice structure and projects themselves.

RIBA CEO, Alan Vallance, said: “The findings of our survey – and best practice examples that follow – show that RIBA members

otherwise known as Approved Document B. These changes will ensure sprinkler systems and consistent wayfinding signage are mandatory in all new high-rise blocks over 11 metres tall when they come into force. The Housing Secretary, mayors and local leaders have also pledged to ensure vital building safety improvements continue during the coronavirus pandemic.

This will ensure the safety of those living in high-rise buildings with unsafe cladding or insufficient fire safety measures is prioritised.

are committed to transforming the built environment, but also that there’s progress yet to be made.

“Architects, clients and policy makers understand the need for change, but even more collaboration is required to turn this ambition into action.

“While the RIBA continues to lobby the UK Government to adapt the Building Regulations to meet the scale of our environmental challenge, architects are uniquely placed to lead the green recovery of the built environment post-pandemic. This means applying the Sustainable Development Goals consistently, and encouraging clients to do the same.

“It’s time to kick-start a decade of action, sign-up to our 2030 Climate Challenge, and make sure we’re building a future that will last.”

The RIBA Sustainable Outcomes Guide aligns with the UN Sustainable Development Goals, and outlines eight clear, measurable goals for projects of all scales, underpinned by specific design principles to achieve them.

Landmark ecodevelopment takes a step closer

Scotland’s largest carbon-neutral development has taken a step closer as the full planning application was submitted this week.

The John Dewar Lamberkin Trust has submitted proposals for a mixed-use development as a sustainable expansion to the city of Perth including plans for a national innovation business park and some 1,500 homes, leisure and educational provision supported by a smart energy grid. The Perth West project will be a catalyst for Perth’s ambition to become the most sustainable small city in Europe and will have a transformative effect on the economy of Scotland.

First WELL Platinum certified co-working office in the UK

Uncommon’s newest space, opening in early 2021, known as Uncommon Holborn, has been registered for WELL Core Certification.

The scheme aims to become the first Platinum Certified WELL Core office in the UK, and the UK’s first WELL Platinum Certified co-working space, demonstrating excellence and thought leadership in design for people’s health and well-being.

The WELL Building Standard specifies how the design and function of buildings can be optimised in order to advance human health and well-being. It covers 10 core building design and operational elements, including: air, water, nourishment, light, movement, thermal comfort, sound, materials, mind, and community.

Industry calls for National Skills Task Force as redundancies loom

Britain’s manufacturers are calling for the establishment of a National Skills Task Force as companies are bracing themselves to have to make substantial redundancies as the rate of decline in orders accelerates and pessimism about a return to normal trading within the next year has grown according to a new survey.

In response, Make UK is calling for the establishment of a Task Force which would have the objective of retaining key skills within industry by re-deploying employees who have lost their jobs to other companies and enabling them to be re-trained. A smaller such scheme was set up after the Financial Crisis but Make UK believes there is now a case to establish a much bigger scale project on a national basis.

The survey also comes ahead of an expected announcement by the Chancellor of the Exchequer on plans to gradually unwind the Job Retention Scheme and a requirement for employers to make an increased contribution to the salaries of furloughed staff. In response, Make UK is urging the Chancellor to provide employers with as much clarity and certainty as possible to enable them to plan any restructuring, together with increased flexibility in the scheme to allow for part time working two days a week.

“There is no disguising the fact these figures make for awful reading with the impact on jobs and livelihoods across the UK. Industry and Government must now leave no stone unturned to retain as many key skills as possible within the sector to ensure it is in a position to effectively recover when growth eventually returns, which at some point it will,” said Stephen Phipson Make UK Chief Executive.

“As part of this Government should establish a National Skills Task Force with the aim of retaining and re-deploying as much talent within the sector as possible. This will help ensure that companies have the necessary skills and capacity to be quick out of the blocks for any upturn in demand.

“In addition, the Job Retention Scheme has been very effective in allowing employers to retain as many of their staff as possible. But, industry accepts that it cannot continue

indefinitely and will understand the plans to reduce the cost to the taxpayer and ask companies to make a greater contribution.

“In doing so, however, the Chancellor should provide as much clarity and certainty for companies as possible whilst, at the same time, introducing an element of real flexibility into the scheme which allows for part time work.”

According to the latest Covid 19 Manufacturing Monitor published by Make UK, the manufacturers’ organisation the number of companies now operating in some capacity continues to grow, standing at just under 95%. However, despite this a quarter of companies plan to make redundancies in the next six months with a further 45% possibly planning to do so. At this stage, just under a third of companies (30%) do not plan to make redundancies.

Of those who plan to make redundancies, over a third of companies (33.3%) plan to make up to 10% of employees redundant, just under a third (31.1%) up to a quarter of employees, whilst more than a quarter (28.9%) plan to make up to half their staff redundant.

Make UK also warned that the rate of decline in orders has increased compared to the last survey two weeks ago with the number of companies reporting order declines of more than half up from just under a quarter to just under a third (31.8%) while those reporting declines of up to half also increased from just under a quarter to just over (27.1%).

Furthermore, the number of companies who believe it will take more than a year to return to normal trading conditions has also grown slightly from the last survey, up to just under four fifths (37.8%) from 36% two weeks ago. The extent to which pessimism amongst companies has grown is highlighted by the fact the figure for the same question stood at just 17% of companies a month ago.

Fassa Bortolo is a historic name in the world of building. Attention to quality raw materials, research, innovation and the environment have always been at the basis of the company’s vision, expressed through the continuous development of state-of-the-art solutions for the evolution of building.

Metal mesh ceilings#LookUpAndBeInspired

WITH FLEXIBLE AND REMOTE WORKING BECOMING INCREASINGLY POPULAR IN THE OFFICE ENVIRONMENT - ARCHITECTS AND DESIGNERS ARE WORKING MORE CLOSELY WITH CLIENTS TO CREATE MORE INVITING WORKSPACES. SO, WHEN EMPLOYEES ARE IN THE OFFICE, IT PROMOTES A STRONGER SENSE OF COMMUNITY AS ANTHONY MILLINGTON, BUSINESS DEVELOPMENT MANAGER AT AMRON ARCHITECTURAL EXPLAINS.

When designing modern corporate spaces, it is almost unanimously agreed that sustainability is key. With the use of recycled and sustainably sourced products, we are seeing that ceilings are now being designed to relate to this approach. Instead of using a product such as a mineral fibre tile which although very affordable, they can crack, stain and mildew in time creating a rather depressing environment.

Architects and Designers are looking at more novel approaches to the ceiling space, among them we are seeing an increase in use of metal meshes both from a point of view that they are generally made from recycled material in the case of aluminium and steel – but also the style and look of them has that upcycled feel that we are all trying to be more conscious of.

Dropped ceilings were first introduced around 100 years ago, they were a novel idea to hide building infrastructure such as ducting and pipework and creating a space to allow access for maintenance – this is

where the mineral fibre tile came in as the most cost effective way of creating the dropped ceiling. They were cheap, thick and relatively good acoustically. However, now with the option to use metal mesh in ceilings, it allows a dropped ceiling whilst offering benefits including improved airflow, lighting and vastly improved aesthetics.

Amron Architectural worked closely with Orms Architects and internal fitout company, Oktra, when specified for a large-scale office refurbishment on Southwark Bridge Road, London. Due to the unique triangular shape of the building, the dropped ceiling needed to follow the triangular floor print. The ceiling system needed to incorporate an expanded mesh to enable lighting to show through the mesh. The system was designed with individual framed triangles, allowing for ease of install to drop Amron’s RB35 directly into the frames –resulting in a completely bespoke ceiling being designed, manufactured and delivered for five floors of this high-profile office building.

Metal Mesh Ceilings are an ideal choice to achieve an industrial and contemporary look

for any project. Our standard metal mesh ceiling tile range is designed so you can use a standard ceiling system, 15mm or 24mm, for new installations or retrofit of existing systems. Amron also offer bespoke ceiling systems based on your design.

The benefits of UK manufacturing

UK MANUFACTURING HAS RECENTLY SEEN A RESURGENCE, NO DOUBT AS A RESULT OF ITS ABILITY TO DRIVE DOWN LEAD TIMES, ENABLE BETTER CONTROL AND LOWER BUSINESSES’ CARBON FOOTPRINT. KEVIN BOHEA, MANAGING DIRECTOR FROM SPECIALIST MANUFACTURER STORMKING, MAKES A CASE FOR UK MANUFACTURING, HIGHLIGHTING THE TANGIBLE DIFFERENCES IT IS MAKING TO THE INDUSTRY AND THE ENVIRONMENT.

hilst the construction industry is truly international, there has been more of a conscious effort in recent years to bring UK manufacturing and the products the sector produces back into the limelight. UK manufacturing has always been known for quality but typically we often find it difficult to compete with price, even if a lower price means lower quality. However, home-grown products now represent something a little different; environmental benefits such as reduced travel and associated carbon, a better appreciation of the true value and better lead times.

Far from being sentimental, this attitude to British manufacturing is doing great work for the UK’s identity as a pioneer and international market-leader of calibre products and manufacturing innovations. UK manufacturing is also serving an integral purpose at the moment; whilst many borders remain shut or restricted during the Covid19 pandemic, it is extremely reassuring to see that one of Britain’s core industries can continue to operate.

Quality control

The need for building quickly and at reduced costs, together with stringent health and safety standards, means construction and design companies across the nation require quality products which hit the mark on safety. A reliable indicator of quality is the international suite, ISO 9001:2008, the certification for quality management. Accredited by the British Board of Agrément (BBA) and the United Kingdom Accreditation Service (UKAS), this standard recognises that the policies, practices and procedures of UK manufacturing firms is of the highest quality.

The UK is known for setting the bar high in terms of quality and it is this combination of compliance and innovation which ensures the manufacturing industries deliver on what they promise.

Sustainable

As well as assuring quality, UK manufacturing also has an important function in terms of sustainability. Climate change is having a damaging effect on the outside world. It is why the industry has a responsibility to do its very best to mitigate the risk it poses,

whether it is lowering transportation times, or delivering to sites in ‘one hit’.

Moreover, companies such as Stormking comply with the environmental management standard, ISO 14001, in order to enhance their environmental performance. For instance, the GRP products which Stormking manufactures are all produced in accordance with this internationally-recognised standard.

Established in 1985, Stormking is the construction’s industry’s largest specialist manufacturer of offsite, prefabricated GRP component products. Offering a wide product portfolio – including chimney stacks, bay window roofs, dormer windows and door canopies – and the most advanced offsite manufacturing techniques, Stormking’s solutions provide both cost and time savings on all types of building projects.

With over 35 years’ experience in offsite construction Stormking continues to innovate, offering a high-quality product range that meets the requirements of the UK industry. Being a UK manufacturer, Stormking is agile and can identify a product so the client and end customer gets exactly what they want; an engineered product which is designed to last and has the aesthetics and quality we have come to expect from UK manufacturing.

UK manufacturing is proving its worth in more ways than one whilst Britain fights against the Covid-19 pandemic. As well as assuring the construction industry keeps delivering on quality, it is enabling the sector to normalise productivity levels in the face of significant adversity. ‘Made in Britain’ is more than just a slogan; it represents the quality which the UK is renowned for in times of both peace and virus.

Schöck creativity at new Greenwich Design District

THE O2 ARENA ON THE GREENWICH PENINSULA HAS A NEW NEIGHBOUR – GREENWICH DESIGN DISTRICT –PROVIDING 14,000M2 OF AFFORDABLE STUDIOS AND WORKSHOPS FOR CREATIVES WORKING ACROSS AREAS AS DIVERSE AS DESIGN, FASHION, ART, MUSIC AND DIGITAL TECHNOLOGY.

his pedestrianised, vibrant neighbourhood, comprises sixteen free-standing buildings, situated around five courtyards and a central public square. With the exception of the single level Food Hall, the buildings range in height from three-to-five levels and are a mix of reinforced concrete, structural steel and cross-laminated timber.

Minimising thermal bridging is crucial Improved thermal performance is becoming increasingly important in large new build developments and the prevention of thermal bridging has a huge role to play. Ineffectual insulation at cantilever connectivity points results in local heat loss, requiring more energy to maintain the building’s internal temperature. Low internal surface temperatures around the thermal bridge can also cause condensation, leading to structural integrity problems with absorbent insulation products and the potentially serious occurrence of mould growth

Design freedom from Schöck

As the leading international supplier of structural thermal breaks, Schöck has hundreds of variants in its Isokorb range, offering a solution to practically any design detail. The predominating Isokorb at the Design District is for concrete-to-concrete, but not all of the requirements were so relatively straightforward. Building C1 is a prime example. Set on the east side of the main entrance, this three-level workshop and studio building has a basketball court on the roof.It has unusually deep floor zones, several large cantilevered elements and a steel mesh enclosure supported on a braced-steel frame around the court, which utilises Isokorb elements for concrete-to-steel detailing. There is also an external staircase and concrete cantilevered walkway. Where the walkway encloses the staircase, there are particularly large cantilevers and here the walkway slabs, supported by a main beam, enclose cast-in steel beams and three cross-beams. These are bolted back to the structural slabs using Isokorb units for steel-to-steel construction and steel construction-to-concrete slabs.

Large capacity thermal breaks required

Building D1 is a community of studios, workshops and office spaces, which structurally consists of robust concrete slabs – with trees located on the external decks. Some extremely large capacity structural thermal break elements were developed to take the loads. Other buildings that incorporate Schöck Isokorb solutions are A1; which marks the main access to the Design District. D4, with its tall slim facade; and A4 on the western edge of the site, which welcomes visitors with a large roof-mounted illuminated sign.

Totally verifiable performance

The comprehensive Schöck Isokorb range enables concrete-to-concrete, steel–to-steel and concrete-to-steel detailing. And there are solutions too that provide a maintenancefree alternative to wrapped parapets; along with a product which thermally insulates connections for reinforced concrete walls and columns. Products meet full compliance with the relevant UK building regulations, have NHBC approval and offer LABC Registration. There is also the security of independent BBA Certification.

A new warm and quiet Engineering School at Imperial College London

IN 2016 IMPERIAL COLLEGE LONDON ACQUIRED THE NEIGHBOURING DISUSED ROYAL MAIL POST SORTING OFFICE FROM THE SCIENCE MUSEUM, SITTING ON THE CORNER OF EXHIBITION ROAD AND IMPERIAL COLLEGE ROAD.

Planning was granted to covert the four storey building into the new ‘Dyson School of Design Engineering’, which was made possible by a £12million donation from the James Dyson Foundation. However, the period features, including the original single glazed windows, had to be retained.

Pascall+Watson devised the architectural plans, which included minimising carbon consumption and reducing energy wastage, inline with the College’s Environmental Policy.

Significant amounts of heat and energy can be lost through old single glazed windows, so secondary glazing was specified to improve performance with 6.8 low-E laminate glass. This combination can reduce U-values to 1.8 – 1.95 and with high performance seals, 60% of heat loss can be reduced and draughts eradicated.

Over 180 windows across the building were treated, with seven different styles of secondary glazing to match the varying sightlines and shapes. Series 41 side hung casements were used for the large curved headed windows, Series 20 and 25 vertical sliders mimicked the traditional box sash windows and circular units were produced for high level port hole windows at the top of the building.

In addition to energy efficiency, other requirements were met. Obscurity glass was used in windows overlooking the service area of the Science Museum to prevent distractions. The secondary glazing on facades facing busy thoroughfares, was fitted with a cavity to attain high levels of noise insulation. To protect new costly equipment in labs and teaching areas, Secured by Design units were installed.

The benefits of warm roof design in the UK

By Iain Fairnington, Technical Director – A. Proctor Group

The traditional approach

Traditionally when we think of pitched roofs in the UK, we are referring to a pitched roof utilising slates or tiles (discontinuous roofing) above a roofing underlay which may have been bituminous felt in the past but is now more likely a vapour permeable underlay which could be airtight or air permeable.

Essentially, pitched roof design has been developed to provide water protection to the building with the high pitch coupled with discontinuous slate or tiles as the primary water-shedding layer backed up by the roofing underlay which provides secondary water-shedding protection along with taking wind loads imposed onto the pitched roof. Designed and installed well this provides a dry roof space along with ventilation products (holes in the outer layers) or with

an air permeable underlay which allows air to circulate through its structure while taking a proportion of the wind loads.

This pitched roof design has been used extensively within the UK and affords the title of a “cold pitched roof”. In general, with a few additions such as increased insulation at ceiling levels, increases to ceiling details including a well-sealed ceiling, high level/ ridge ventilation and the introduction of an improved underlay in the form of an air permeable underlay, the UK traditional approach still favours the “cold pitched roof option” but why?

A cold pitched roof provides the following advantages-

• Good weather protection

• Uses traditional trades- roofers and joiners

• Uses traditional materials such as slates and tiles

• Provides a dry loft space

Warming to the benefits

The question is, should we be utilising this same pitched roof design but enhancing it with the use of a warm pitched roof design, commonly used in Europe?

The warm pitched roof design provides all of the above benefits, however, it also allows the dry loft space to be utilised for accommodation. Interestingly it was once suggested that if the cold roof design had continued to use the old cut timber roof as opposed to the cheaper truss rafter the increased accommodation in the years since would have housed a population similar to Sheffield.

IN THIS ARTICLE IAIN FAIRNINGTON, TECHNICAL DIRECTOR OF THE A. PROCTOR GROUP HIGHLIGHTS THE POTENTIAL BENEFITS OF WARM PITCHED ROOF DESIGN IN THE UK.

Our European counterparts believe that constructing a dry loft space, only to house items such as Christmas tree, suitcases and your old school reports is a real waste. With very little extra design and cost this loft space can provide valuable accommodation space which could help ease the markets housing shortage.

Underlay design

However, one area that remains critical is the underlay design and ventilation requirements.

In a warm roof design, where the insulation follows the roof line as opposed to the horizontal ceiling line, the considerations are different. With the smaller roof void (sometimes non-existent, between the insulation and the underlay) we need to be more conscious of vapour and moisture dynamics such as –

• Vapour drive through the roof structure

• Airtightness of the roof

• Vapour permeability of the insulation

• Potential of insulation wind wash

• Safe protection of driven rain

• Safe escape of moisture

• Wind uplift

• Wind “chattering” so near the living/ sleeping area

• Ventilation space above the insulationnone or 50mm depending on vapour permeability of underlay

There is an increasing acceptance of air and vapour permeable underlays (APLR) e.g. Roofshield in the UK cold pitched roof designs along with the many benefits they bring for a ventilation free, fail-safe solution. However, these benefits are less obvious in warm pitched roofs. The vapour and air permeable underlay (APLR) still has the

benefit of low vapour resistance in warm pitched roofs but the air permeability benefit is less important. This is due to the vapour resistance of the build-up below it, whilst high vapour resistance and installation of a vapour control layer become more crucial due to the lack of buffering effect in the large air void evident in cold roofs.

If we change our mindset to embrace the above-mentioned benefits, we can also embrace new technological advantages in pitched roof underlay design. With higher vapour resistant rigid boards being installed on the roof line this provides an ideal fully supported base for a self-adhered vapour permeable yet airtight underlay such as Wraptite. This underlay has been certified by the BBA specifically for this application and provides the benefits of an airtight underlay.

The positioning of the underlay may influence the choice of underlay, where over the counter battens will be less advantageous when used with a loose laid underlay with open joints being draped over the counter batten to offer drainage below the tile batten. The ventilation below the tile batten will not be a concern where the underlay is laid fully supported on the insulation below the counter batten.

Where the future lies in the UK pitched roof design is subject to debate but the stark reality is that warm roof design offers significant benefits in providing an energy-efficient warm space with increased accommodation possibilities. However, designers need to be aware of the subtle differences between this and the traditional cold roof design. If these considerations are taken into account at the design stage along with the new technologies available then the industry has a positive answer to many of the questions being asked of the traditional cold roof.

AJ Specification Award winning project ‘The Forge’ in London E6 epitomises the way forward in rainwater management in the UK.

‘This project demonstrates good design team collaboration and joined-up thinking,’ said the judges . ‘It responds to the city’s challenge – of not being able to put things in the ground – and uses specification to turn the scheme on its head, with a high-quality outcome.’

A key constraint of the original planning consent for this residential scheme was the site’s limiting maximum discharge rate for surface water of 3.3 litres per second – resulting in the scheme sitting within what’s known as a ‘critical drainage area’, and posing significant design challenges in terms of drainage.

Radmat’s Blue40 Roof systems provided a key element of the source control and attenuation required by the sites Sustainable Urban Drainage System (SuDS) strategy; attenuating rainwater rather than draining it quickly.

9mm Magply given ‘purple passive’ treatment for Peckham properties

A DEVELOPMENT OF TWO AND THREE BEDROOM TERRACED HOMES ON A BROWNFIELD SITE IN SOUTH LONDON IS MAKING USE OF MAGPLY BOARDS’ FIRE RESISTANCE AND OTHER PHYSICAL BENEFITS: RECEIVING A SPECIAL POLYMER BASED, PURPLE COLOURED MEMBRANE FINISH TO PROVIDE EXCELLENT AIRTIGHTNESS AS PART OF AN ‘ECO-HOMES’ ENERGY SPECIFICATION.

The four new houses in Peckham for Emerson Properties are being built by Cambridgeshire based White Haus, a package contractor specialising in high performance timber frame structures up to PassivHaus standards, which has specified Magply on a previous project in the borough, as well as elsewhere around the country. In this instance, the high performance MgO boards will be overclad with black timber boarding across a batten cavity, with widths varying from 50-120mm which conceals the rainwater downpipes draining the homes’ green roofs.

The Project Manager for White Haus, Tony Buck, commented: “We offer clients a bespoke service for the supply and installation of high performance timber frames to meet various specificationsright up to PassivHaus standard – building schools, hospitals and commercial premises

as well as domestic properties.

Although these structures aren’t within the designated five metre distance of existing buildings, the client (Emerson Properties) wanted the additional protection provided by a fire rated sheathing board – in addition to fire rated timber cladding - and we are using 9mm Magply boards on the outside of the timber frames. “

“It is being treated with our Passive Purple, vapour open membrane which allows the structure to breathe while achieving very good airtightness. Together with the closed cell, Lapolla polyurethane foam insulation, the wall construction offers excellent energy performance.”

Magply boards carry a range of international certifications, including KIWA, a BDA Agrement awarded last year, while their fire performance has been verified

through industry standard tests at the world renowned Warrington fire research centre. Following a number of high profile blazes on building sites, such as at Hendon in North London, responsible timber frame manufacturers have been working to reduce their systems’ vulnerability to fire and Magply provides far better performance than plywood or OSB: offering instant protection rather than requiring additional layers of plasterboard.

Additionally, Magply’s unique production process keeps the chloride content to just 0.01%, enhancing both stability and longterm durability. Therefore, when employed as an exterior sheathing board, Magply is often left exposed to the elements for extended periods during the erection of structures such as apartment blocks.

Cut-to-falls Multiboard spec speeds protection of semibasement to Somerset home

AN ARCHITECT LED REFURBISHMENT PROJECT ON A PRIVATE RESIDENTIAL PROPERTY NEAR EXMOOR HAS INCLUDED THE SPECIFICATION OF CUT-TO-FALLS MARMOX MULTIBOARD, CHOSEN FOR THE VERSATILE PRODUCT’S HIGHLY BENEFICIAL PHYSICAL PROPERTIES, TOGETHER WITH THE PRACTICAL CONSIDERATIONS TO THEIR INCLUSION.

The work on the home on the North Somerset coast, is being carried out by sector specialist builder and developer, NTG Property, while Peter Reid of P2 Design drew on his experience of using Marmox Multiboard, to address past problems, when faced by a semi-basement space whose concrete roof structure was leaking badly. The original waterproofing membrane having cracked and deteriorated, with damp penetrating the habitable room below.

Peter Reid commented: “As a practice we work right across the UK and have used Multiboard on a wide range of past projects, for applications such as lining existing walls or upgrading floor constructions prior to installing underfloor heating. It really is a very useful and adaptable product, ideal for refurbishment because of its thermal and

waterproofing performance. In this case there was a habitable semibasement level where water had been getting in over a long period and causing damage and while it wasn’t designed under the Building Regulations but considered a repair of the existing, we went to Marmox to obtain calculations on the heat loss: to maximise the energy retention and avoid any risk of interstitial condensation forming within the new build-up. And there was also the added bonus that utilising the tapered boards allowed us to speed construction and do away with one of the wet trades. It has been a very successful application.”

With the 125mm concrete slab broken off the original beam-and-block roof structure and all the old phenolic foam insulation removed, the substrate was treated with a bitumen based, Alutrix, waterproof adhesive and the first of four layers of 20mm Multiboard

bonded down. Subsequent layers, including the cut-to-falls sections, were laid with staggered 10mm joints: the uppermost being sealed using Marmox Jointing Tape. This was followed by the installation of stylish porcelain tiles with a waterproof grout detail to complete a classic, ‘inverted’ promenade deck or patio. All of the Marmox Multiboards and Marmox Tape were supplied through Boyden Tiles in Croydon. Marmox Multiboards are manufactured from extruded polystyrene or XPS and offer a range of positive physical characteristics in addition to being fully waterproof.

They are both light to handle and easy to cut, while still being able to sustain substantial loadings if required. They further offer good thermal insulation performance, helping to cut condensation risk. Marmox

P C Henderson donates hardware to assist school rebuild in Nepal

SLIDING AND FOLDING DOOR HARDWARE MANUFACTURER, P C HENDERSON, HAS RECENTLY DONATED MATERIALS TO HELP WITH THE REBUILD OF A PRIMARY SCHOOL IN NEPAL AFTER IT WAS LEFT DEVASTATED BY AN EARTHQUAKE IN 2015.

Situated on a picturesque mountainside, the village of San Bhorle was left in ruins when the 7.8Mw earthquake hit, levelling every one of its 43 houses and primary school. All but one resident survived, but the community was left to rebuild their lives with no materials, tools or machinery.

Learning Planet, a charity which helps remote communities design, finance and construct new schools, stepped in to help. As the only communal building in the village - and the only one which would have permanent power and internet access - the local community required a school building which could also be used for other events such as village meetings and celebrations.

In order to achieve this level of flexibility, large bi-folding doors were needed in the centre of the building. This would allow the area to be used as a classroom when closed off or put to other uses when opened up. A folding partition wall was also to be installed in one of the classrooms, allowing teachers to create a private office space when necessary.

P C Henderson’s Securefold system was identified as the best solution for the project. Carrying ten solid hardwood doors measuring 225cm high x 50cm wide - it was important that the system could comfortably cope with a heavy load - whilst still allowing for effortless and safe opening by adults and children.

University turns to revolutionary fan

BRUNEL UNIVERSITY LONDON’S HAMILTON CENTRE IS HOME TO A HOST OF ENTERTAINMENT FACILITIES, INCLUDING BARS, RESTAURANTS, AND THE STUDENT UNION. WITH THE LINK BETWEEN GOOD INDOOR AIR QUALITY (IAQ) AND CONCENTRATION LEVELS BECOMING INCREASINGLY WELL ESTABLISHED, OPTIMISING THE BUILDING’S VENTILATION SYSTEM WAS A TOP PRIORITY.

ocated in the heart of Middlesex, Brunel University London is home to over 12,000 students across a wide range of disciplines. It was founded in 1966, and has grown to become one of the top universities in the world, regularly ranking in the top 400.

As a campus university, there are a range of facilities located on site for students to enjoy, from shops and bars, through to gyms and nightclubs. The Hamilton Centre houses much of the entertainment for students, as well as the student union. It is a place where large numbers of people frequently meet, congregate, and spend their spare time, which makes it crucial that it is as comfortable and welcoming as possible.

There is also evidence that poor IAQ has a negative effect on the attention span of students, leading to a noticeable drop in concentration when CO2 levels are high. Combined with longer-term effects such as headaches, coughs and respiratory problems, it is crucial that education facilities make a conscious effort to ventilate as effectively as possible.

A contra-rotating fan on the roof of the Hamilton Centre, which was directly responsible for ventilating a popular pizza bar in the building, was failing. It had been over specified, which meant it was oversized and using an unnecessary amount of energy.

Marcus Sawkins, Co-Founder and Managing Director of GFMS Services Limited, comments: “Although it is important to maximise the performance of a ventilation system, this must be balanced with the associated energy expenditure.

“The existing fan was incurring high running costs and CO2 emissions, neither of which are desirable for an expanding university. Plus, the voltage required to operate the fan was unnecessarily large, which posed a problem as the controls are located in a busy kitchen.”

The decision was made to replace the fan with a more energy efficient model, but it was crucial that performance was not sacrificed. Owing to its reduced running costs, EC motor, and intuitive controls, Elta Fans’ Revolution SLC EC presented itself as the ideal fan for the application.

The transition from an AC motor to a low energy EC motor negates the need for a mains powered speed controller. As David Millward, Product Manager at Elta Group explains, this has a two-pronged effect: “The EC motor helps to reduce energy bills by up to 20%, which is crucial for meeting environmental targets as well as lowering the total cost of ownership. It is also a more straightforward installation, allowing contractors to complete projects quicker and with less chance of complications.”

As indoor air quality continues to dominate the agenda, there will be increased emphasis on providing adequate ventilation for building occupants. Choosing a fan based on the actual required level of ventilation is critical, as performance must be matched with running costs and overall energy expenditure. By combining an EC motor with intuitive controls and a precisely engineered impeller, it is possible to achieve optimum performance without incurring crippling energy bills.

The successful specification of anti-terrorism solutions

PROFESSIONALS INVOLVED IN THE PLANNING, DESIGN AND ONGOING MANAGEMENT OF PUBLIC SPACES AND STREETSCAPES MUST CONSIDER AND ADDRESS A NUMBER OF FACTORS WHEN LOOKING AT SITE SECURITY AND SAFETY. HERE, MARK LESTER OF HÖRMANN UK, EXPLORES THE KEY ISSUES AND THE SOLUTIONS AVAILABLE TO HELP MITIGATE AGAINST POTENTIAL TERRORIST THREATS, WITHOUT ALTERING THE OVERALL LANDSCAPE.

As crowded places remain an attractive target for terrorists, architects and specifiers have an increasing challenge to successfully blend counter-terrorism protective security measures with the urban design principles of the public space they’re creating.

Within the government’s ‘Protecting Crowded Places: Design and Technical Issues’ guide, it provides those involved in the development and maintenance of the built environment with a comprehensive basis for the appropriate specification of anti-terrorism solutions. The document offers advice and guidance on how high design quality can be upheld throughout the commissioning and planning of new development schemes, without impacting on the overall style and intention of the place in question.

Using this guide as a basis, professionals should first understand the varying circumstances and associated degrees of risk that each project presents, before looking to specify solutions that aim to reduce the vulnerability of the location from a terrorism perspective.

For many public spaces, its crowd density may be temporary. In this instance, a specifier will be responsible for locations housing concerts or events that do not have a constant level of visitors, rather one that is concentrated at peak times. Here, the specification of temporary anti-terrorism solutions present an appealing approach as the desired attraction of the space can easily be retained, without compromising the safety and security of the environment during high footfall periods.

One of the main benefits of temporary antiterrorism systems that are designed to specifically manage hostile vehicle mitigation is that they offer the potential for continued flexibility, particularly when compared to fixed systems that must be permanently installed. As the very nature of temporary systems lends their application to a wide range of configurations that can be transported to different areas of the location, the evolving requirements of the environment can continue to be met, without impacting on the level of security and safety provided.

By first assessing the potential levels of security risk the space presents, professionals can

then understand the integrity of the protective technologies required. Here temporary systems, such as certified single units, enable professionals to successfully meet the exact levels of integrity needed, as the quantity and configuration is tailored to the individual project and its level of risk.

For example, mobile vehicle blockers that are certified as a single unit can provide effective protection against unauthorised vehicles, without restricting pedestrian access or altering the intention and accessibility of the urban public space. As the solutions are temporary, consideration of the subsurface and the materials specified do not need to be addressed, as no physical fixings are required to keep the blockers in place.

This also offers significant cost and resource savings throughout the lifetime of the project, whilst ensuring the continued adaptability of the systems to best meet the specified requirements and intentions of the environment as it evolves.

The benefit of a solution that can be arranged individually, in rows or offset, offers a completely flexible system that does not require any compromises to be made to the initial design

plans and can adapt to meet the specific needs of the space. For example, narrow pavements or cycle paths can be effectively secured with a single blocker unit, whilst a sluice or slalom arrangement can create defined passage points for emergency and rescue vehicles.

Architects should also look to explore blockers that feature axisymmetric geometry as they have no predefined impact side. This means the angle of the collision is inconsequential, providing the highest levels of security, regardless of the direction the vehicle is travelling from.

Temporary solutions may also be an effective consideration for the retrofitting of anti-terrorism systems at historical or sensitive sites, such as conservation areas, where fixed solutions would impact the physical design and integrity of the site.

To ensure compliance with all relevant legislations and provide a clear audit trail of due diligence, professionals must specify hostile vehicle mitigation solutions that have been certified according to internationally recognised standards and standardised crash tests. This will evidence the products can withstand the force of a specific test weight and speed, enabling architects to specify solutions that are tailored to meet the integrity requirements of each specific project.

By taking a proactive approach from the initial concept stages and working closely with manufacturers, professionals can ensure the anti-terrorism solutions they specify are not only fit for purpose, but have minimal impact on the overall design intentions of the project.

IN DECEMBER 2016, THE EQUALITY AND HUMAN RIGHTS COMMISSION REVIEW STATED THAT THERE WAS ‘A SEVERE SHORTAGE OF ACCESSIBLE HOUSES’ ACROSS BOTH THE PRIVATE AND PUBLIC SECTOR. HERE STUART REYNOLDS, HEAD OF PRODUCT AND MARKETING AT AKW, EXPLAINS HOW SPECIFIERS IN BOTH THE PRIVATE AND PUBLIC ARENA CAN CREATE WELL-DESIGNED WHEELCHAIR ACCESSIBLE BATHROOMS, COST-EFFECTIVELY.

The first thing to understand is that well-designed wheelchair accessible bathrooms needn’t cost the earth but should incorporate some well-designed necessities, so that the space is fit-forpurpose and effective in the long-term.

So, what does a well-designed bathroom look like when it comes to a wheelchair accessible bathroom? There are a range of common elements that should be included when specifying or installing any wheelchair accessible bathroom. The following is some best practice advice taken from the Building Regulation’s Doc M for wheelchair user dwellings and also from Kate Sheehan, Occupational Therapist of The OT Service for a well-designed wheelchair accessible bathroom. For the full story, download the wheelchair design guide on AKW’s website.

Promote

movement around the space

• Manoeuvring into and inside the bathroom are key considerations. With this in mind:

• Prioritise level access throughout the space – use a wet room former, or a recessed or ramped shower tray

• Ensure doors are outward facing – this increases space in the bathroom and helps in case of emergencies

• Ensure easy and safe level shower access – this can be done by using a corner design for the shower space

• Minimise any gradient near the WC – a level access shower area has

a gradient to help the water drain. Ensure that this is not part of the WC transfer zone, to minimise wheelchair tipping hazards

• Incorporate a raised height toilet – to allow for easier transfer from wheelchair to toilet seat

• Ensure toilet accessibility on both sides if possible – this is best-practice advice and facilitates transfers, personal assistant support and potential changes in need for the wheelchair user

• Ensure that there is no external plumbing and pipe work – to promote ease of movement around the space, all pipework needs to be concealed within the walls

• Think about the placement of radiators or towel rails –these can hinder wheelchair movement. Always opt for low surface temperature heat sources and consider underfloor heating as an alternative

• Use slip-resistant flooring – to maximise the traction of the wheelchair and minimise falls

• Use a wall hung sink – to improve access. Consider one with handles or a concave design to make things easier for a wheelchair user. The sink’s height should also be tailored to the user’s requirements (although compromises might be needed if the space is also used by the wider family).

Restoration success for AgriSTEM Academy

WHEN SOUTH STAFFORDSHIRE COLLEGE RECEIVED FUNDING TO DEVELOP A NEW LEARNING CENTRE, RATHER THAN BUILD EVERYTHING FROM SCRATCH, IT SEIZED THE OPPORTUNITY TO RENOVATE ITS HISTORIC GRANARY BUILDINGS. THE AGRISTEM ACADEMY IS SOUTH STAFFORDSHIRE COLLEGE’S CENTRE FOR TRAINING IN THE ADVANCED MANUFACTURING AND ENGINEERING (AME) AND AGRICULTURAL ENGINEERING AND TECHNOLOGY (AGRITECH) SECTORS.

hosen architect practice, maber, was tasked with designing and refurbishing the buildings for the new academy, with the granary building as the project showpiece.

The project was fully modelled in design software ARCHICAD, with one of the biggest challenges being the translation of historic drawings and 2D survey information into an accurate 3D model. This was relied on to carefully meld the old with the new.

A top to bottom renovation

Having stood empty for many years, the granary wasn’t structurally safe for educational requirements, nor was it adequately insulated.

The granary was thermally upgraded using a consistent insulated fabric that sealed the

roof and walls. Foiled tape joints allow for a low target air leakage rate. Despite the roof needing to be completely removed, the contractors kept the original slates and reused them on the front roof slope to maintain the original aesthetic. Heritage roof lights were also incorporated into the design, to bring additional natural light into the building.

The existing floor was removed to install the new steel foundations and provided an ideal opportunity to insulate and add waterproofing to omit any damp in the building.

As bats were known to be nesting on site, throughout the project the team had regular checks with the ecologist to make sure the renovation would not negatively impact on the bats’ habitat. For example, the team used a traditional roof membrane to prevent bats

from getting their claws stuck. Meanwhile, habitation boxes designed for the bats were faced with brickwork, so they didn’t detract from the original look of the building.

Using ARCHICAD’s renovation filter it was possible to see which elements of the building would stay, which would be demolished, and which would be new – all within the one model. This eradicated the need for multiple layers and minimized chances of error.

Sustainable fabric and materials

As the buildings previously housed pigs and sheep, a conscious design decision was taken to incorporate agricultural materials into the architecture.

The team selected hardwearing materials such as polished concrete. This provided a smooth, level floor that allows equipment on wheels to be moved with ease and is hard enough to cope with the traffic flow of students wearing outdoor work boots.

The designers chose sustainably sourced oak for doors, frames, architrave and skirting. These are not primed and painted, so they do not chip, become scuffed or require redecorating. Following a little initial investment at the beginning, the life cycle costs will benefit the college budget over time.

The team used ARCHCAD for the interior design proposals, to show the client what the chosen materials and finishes would look like. They assigned materials and textures from the interior design scheme directly to the surfaces within ARCHICAD. And by exporting the model into Graphisoft’s BIMx visualisation tool, they could accurately illustrate the layout and use of the spaces.

The AgriSTEM Academy now boasts a range of facilities including an advanced mechatronics lab, agricultural and construction vehicle simulators and renewable energies workshops. Since completion, the building has been recognised in a number of awards.

Reynaers reduces noise ingress with introduction of

MasterLine 8 SoftTone® REYNAERS, THE LEADING SUPPLIER OF ALUMINIUM SOLUTIONS, HAS LAUNCHED MASTERLINE 8 SOFTTONE® – A PARALLEL OPENING WINDOW WHICH SUPPORTS NATURAL COOLING AND VENTILATION IN URBAN ENVIRONMENTS, WHILE INNOVATIVELY FILTERING OUT NOISE TO DELIVER COMFORTABLE SPACES FOR OCCUPANTS.

By 2050, 68% of the world’s population is expected to live in bustling urban areas, increasing the need for living and working spaces which are both sustainable and comfortable. As outlined in the Acoustic, Ventilation and Overheating (AVO) Guide, achieving these desired results is reliant on innovative architectural solutions which aid the management of noise.

Facilitating natural ventilation in inner-city homes, MasterLine 8 SoftTone® utilises a carefully designed interface between the frame and sash to limit noise ingress. In practice, that enables occupants to open their windows without having to suffer

excessive noise from the urban environment, enhancing comfort and practicality while reducing reliance on mechanical ventilation.

John McComb, Technical Director at Reynaers said: “Alongside sustainability, rapid urbanisation is one of the most influential trends shaping our industry right now. And while this shift reflects the demands of modern lifestyles, it also presents a series of challenges for the construction industry.

“Ensuring residential and office buildings provide comfortable and practical environments is one of those challenges, which is why building products that help to limit the impact of typically noisy

environments are key. Together with Arup, we’re proud to have developed an innovative and sustainable solution which does just that.”

As a parallel opening window, MasterLine 8 SoftTone ® delivers a larger open area per m 2 than traditional opening windows. Coupled with SoftTone, acoustic performance is significantly increased, providing an architectural solution fit for the future.

Allura takes centre stage at ground-breaking new innovation centre

he natural aesthetics, durable performance and dementiafriendly design of the LVT played a central role in helping to create an environment that promotes collaboration and inclusivity.

GSS Architecture and workplace design experts, Design North, engaged closely with multiple stakeholders and consultees to develop the interior design strategy for the project, which was delivered via BIM Level 2. This included parties from Newcastle University, NICA and NICD, the Alzheimer’s Society and research organisations including the University of Stirling’s Dementia Services Development Centre (DSDC).

Scott Stewart, Director and Co-Founder at Design North, said: “Our task was to create interior spaces that were truly accessible, welcoming and inclusive for everyone, whilst encouraging creativity and collaboration between the building’s users. As some floors are open to the public, we needed to ensure that the building was easy to navigate, particularly for visitors who may have agerelated conditions, visual impairments,

disabilities or walking aids, for example. Under the guidance of the DSDC, we took a holistic approach to the whole specification process and designed areas to be ‘dementiafriendly’. In terms of floor finishes, this meant carefully selecting materials and colourways with suitable degrees of light reflectance values and avoiding sudden changes in tonal contrast from area to area and between walls and floors.

“We specified Forbo’s Allura Wood LVT in the Vintage Oak colourway for the staircase, main circulation areas and breakout spaces on each floor; achieving one tonally continuous flooring surface. We were aware that Forbo work very closely with the DSDC to review its portfolio of products and assess them in accordance with dementia design principles. Therefore, this information was particularly useful when it came to making flooring choices.

“The distressed wood effect complements the industrial style of the interior design and the herringbone installation of the planks adds a creative touch. On the upper floors, where the private offices are located, the visually striking Allura design installed in the breakout spaces creates a warm and inviting

dynamic, which will encourage people to come out of their offices and collaborate. The robust nature of the LVT also makes it the ideal solution for such high traffic areas.”

Allura Wood is part of Forbo’s Allura Dryback fully adhered LVT collection. The in-register embossing structures emphasise the texture of the planks for a truly authentic aesthetic and the proven wear layer allows for reduced cleaning and maintenance. Allura Wood LVT also benefits from advanced production technology to ensure maximum dimensional stability and high scratch and stain resistance, so that the appearance of the floor remains as good as the day it was installed.

In addition, Surestep safety vinyl in Beton Concrete was used in areas where there is an increased slip risk, such as the toilets, kitchens and tea points. Offering guaranteed Health and Safety Executive compliant lifetime slip resistance, the stone design matches the desired industrial look and feel of the building and the innovative Step Crystal particles contributes to a clean and fresh aesthetic.

Polypipe delivers water management solution to new £400m university campus

POLYPIPE BUILDING SERVICES, THE UK’S LEADING DEVELOPER OF WATER MANAGEMENT SOLUTIONS FOR THE COMMERCIAL SECTOR, WAS SELECTED TO SUPPLY A WATER MANAGEMENT SYSTEM TO THE UNIVERSITY OF MANCHESTER’S COLOSSAL £400 MILLION MANCHESTER ENGINEERING CAMPUS DEVELOPMENT (MECD) IN THE CITY.

Built environment consultant Arup requested Polypipe Building Services to provide a drainage management system for the eightstorey, 78,000sqm building. This is one of the largest construction projects ever commissioned by a UK university. The Building Services team delivered a plastic solution which incorporated large diameter Terrain FUZE soil and waste pipes. The installation of the system was undertaken by mechanical contractor NG Bailey.

To maximise installation efficiencies, Polypipe Building Services also provided continuous support during the design stage and installation training to contractors on site to improve the efficiency of the installation and commissioning process.

Jonathan Greenwood, Strategic Project Manager at Polypipe Building Services, said: “In order to remove the rainwater, we worked with the design proposal and configured the Terrain FUZE trap in the basement with the expansion of pipe in horizontal runs, which included bracketry and jointing methods.

“We were able to offer a range of fittings and materials that were sympathetic to the aesthetics of the building, while ensuring contractors on site were fully prepared to install the solution when they were delivered to the development.

“We pride ourselves on supplying systems that provide not only multifunctional benefits to the end user, but also financial and manpower efficiencies to our customers during projects.”

According to the university, MECD has been designed to create “world-class facilities for innovation in technology and working practices, and encourage collaboration between researchers, schools and industry”.

The seven-year development, which will have a huge overall floor space the size of 11 football pitches, will house almost 7,000 university students and more than 1,200 staff.

Don Mercer, Mechanical Senior Project Manager at NG Bailey, said: “Having previously worked with Polypipe Building Services on a number of other projects, we were already familiar with the company’s dedication to quality and efficiency and its expertise.

“Being such a high-profile development, we knew Polypipe was the ideal drainage provider for a project of this scale. We were naturally thrilled with the solution Polypipe supplied. It surpassed all expectations. “We look forward to continuing our great relationship with Polypipe Building Services in the coming years.”

MECD is due to open in 2021.

Drainage and water management must be considered at the beginning of a project

ADAM MCKINNON, BUSINESS DEVELOPMENT MANAGER, ACO SCOTLAND, EXPLORES SOME OF THE DIFFERENT TYPES OF DRAINAGE SYSTEMS, HOW TO CORRECTLY SPECIFY, AND THE ROLE THAT TRAINING PLAYS

IN SELECTING WATER MANAGEMENT SYSTEMS.

Drainage comes in all shapes and sizes, with a number of logistical challenges associated with selecting a system for a project. For example, the complex four-way slopes needed for point drainage can be difficult to construct, and require increased excavation and pipework that could be avoided with an alternative system, such as channel drainage.

This is just one factor of many in selecting drainage, which as we’ll outline below, encompasses a range of considerations.

All drainage system manufacturers must ensure products are suitable to meet a specific load classification. To comply with BS EN 1433:2002 standards, all drainage channels are organised into load classes, which are effectively different categories detailing the load-bearing capacity of that product. Ranging from A 15, for pedestrian footpaths and patios, through to F 900, for airports and industrial yards, the standards are a quick way of ensuring that the right channel and grating is selected.

Grated vs Monocast systems

Grated channels offer greater aesthetic versatility, but monocast systems offer better security and integral strength against turning forces. Local environmental considerations affect the preferred channel type – for example, coastal sea air may require a coated product that protects against oxidisation. ACO’s monocast channels are made from Vienite®, ACO’s high strength recycled polymer concrete, which helps to provide this type of protection.

Choosing the correct channel size is crucial in preventing flooding, but also unnecessary expenditure in instances of over-specification. It requires knowledge of rain fall levels in a particular location, alongside various considerations over surface area and types. It can be useful to rely on the expertise of drainage manufacturers, and some offer self-service tools to ease this process, such as ACO QuAD.

Training is key

Training is often the best way of keeping up to speed with product developments, which is a crucial element of correct specification. ACO, for example, offers training sessions on products as well as subjects such as SuDS, and where they are best applied within different projects. Thinking about drainage options from the beginning of a project is the best way to ensure that effective surface water management is implemented in urban environments.

To help those under significant time pressures, some manufacturers – including ACO – have already shifted towards online training sessions. Teaming up with learning

providers, such as Colab, which offers industry-relevant CPDs and on-demand videos from events, helps to ensure construction professionals can stay up-todate, even while on-the-go.

There is no one-size-fits-all with drainage and water management systems, which necessitates a bespoke approach for every project.

By engaging in training and opening a dialogue with manufacturers as early as possible, those tasked with delivering drainage can be confident of providing an effective solution.

Nordic Copper Inside and Out

NORDIC COPPER FROM AURUBIS OFFERS AN EXTENSIVE RANGE OF NATURAL SURFACES AND ALLOYS FOR ARCHITECTURAL APPLICATIONS. THE LAUNCH OF NORDIC DÉCOR ADDS AN EXTRA DIMENSION TO THE DIVERSITY OF NORDIC COPPER, PARTICULARLY FOR INTERIOR DESIGN.

he Nordic Copper range includes Nordic Standard ‘mill finish’ and Nordic Brown pre-oxidised copper offering lighter or darker shades of brown determined by the thickness of the oxide layer. Copper alloys include Nordic Bronze and Nordic Brass, which can also be supplied pre-weathered. And the innovative Nordic Royal is an alloy of copper with aluminium and zinc, retaining its golden colour.

The extensive Nordic Blue, Nordic Green and Nordic Turquoise ranges have been developed with properties and colours based on the same brochantite mineralogy found in natural patinas all over the world. As well as the solid patina colours, ‘Living’ surfaces are available for each with other intensities of patina flecks revealing some of the dark oxidised background material.

Copper Interiors

Copper is already the metal of choice for interior design, as well as architectural cladding and roofing. Now, Nordic Décor takes design opportunities with copper to a new level, with eight embossings for rich surface textures and seven grindings for distinctive matt surfaces – each with

its own warm natural colour tone. Nordic Décor products are well-suited to a wide range of interior applications, such as wall and ceiling cladding – including elevators –highlight surfaces, bars and counters, as well as external cladding. The material can be shaped, edged, milled, lasered, cut and bent.

Nordic Décor Embossing Styles are available in Nordic Brass Weathered or Nordic Royal copper alloys, Nordic Brown and Nordic Brown Light pre-oxidised copper, and Nordic Green pre-patinated copper. They provide regular patterns of raised or recessed forms, some abraded to reveal highlights of the base material colour for additional design effects. Nordic Décor Grindings are available in Nordic Brass Weathered or Nordic Brown. They are abraded with linear, cross-hatched or curved-swirl hairlines to give distinctive matt surfaces.

Luxurious Materials

Nordic Décor has been used throughout a renowned luxury spa enjoying a mountain-top location overlooking Lake Lucerne, where only the best natural materials will do. Architects ‘plus 4930’s’ redesign and remodelling of the legendary 1980s Bürgenstock Spa forms part of the revival of the entire lakeside resort. The

new building retains the character of a stone pedestal with a façade of exposed concrete emphasising the horizontal. On top, it is clad in vertically arranged Nordic Brass cassettes creating a flat surface, interspersed with generous glazing.

But Nordic Copper also forms an integral part of the interior design, particularly in the hotel’s grand entrance which welcomes guests with a blend of natural, warm and soft tones. Here, walls and columns are surfaced in Nordic Décor copper, with a brushed, semi-matt finish. Different Nordic Décor surfaces are used to highlight fireplaces in individual suites, creating a feeling of richness and warmth.

Safe Copper

Nordic Copper is a natural, non-toxic material that is non-brittle and safe to handle and work. Its inherent antimicrobial qualities make it ideal for touch surfaces within buildings. It has a melting point of 1083˚C, ‘A1 (non-combustible material)’ fire classification to EN 13501-1 and, therefore, ‘Class 0’ surface spread of flame, making it suitable for wall and ceiling surfaces in communal areas.

The right insulation is a sound choice

NOISE POLLUTION IS BECOMING A GROWING PROBLEM FOR OUR HEALTH, WELLBEING AND COMFORT. ROCKWOOL EXPLAINS HOW ITS QUIETMARK ACCREDITED INSULATION CAN SOLVE THIS PROBLEM…

According to the European Environment Agency’s recent report entitled ‘Environmental noise in Europe — 2020’ twenty percent of Europe’s population are exposed to long-term noise levels that are harmful to their health which equates to more than 100 million people.

The report goes on to say that long-term exposure to noise can cause a variety of health effects including annoyance, sleep disturbance, negative effects on the cardiovascular and metabolic system, as well as cognitive impairment in children. They estimate that environmental noise contributes to 48,000 new cases of ischaemic heart disease a year as well as 12,000 premature deaths.

A publication from the World Health Organisation (WHO) also highlights that environmental noise leads to a disease burden that is second in magnitude only to that from air pollution*. It highlights that ‘noise causes or contributes to not only annoyance and sleep disturbance but also heart attacks, learning disabilities and tinnitus’.

As the European Environment Agency and WHO have highlighted, noise has a signification impact on our health and wellbeing. So, what can we do about it when it comes to designing buildings?

Modern methods of construction, such as, ventilated rainscreen systems are becoming

an increasingly popular solution for architects and specifiers designing multi-unit residential blocks, office blocks, hotels and multiuse developments.

As an example, Grove Developments, the construction division of The Arora Group, has recently taken a pioneering approach at Crowne Plaza and Holiday Inn Express at London Heathrow Terminal 4.

Connected via a convenient air bridge to Terminal 4, this dual-branded hotel development includes Crowne Plaza and a Holiday Inn Express, with a combined total of 750 rooms. There is also a range of onsite business facilities, including five meeting rooms, to enable guests to be at their most productive during their stay. Minimising external noise from the UK’s busiest airport, where the average number of air transport movements reached 1,295 per day in 2017, was a major factor in this build. To this end, Grove Developments challenged ROCKWOOL to achieve a significant Rw 58dB sound reduction within the façade system used on the development.

Using test results from its Rainscreen Acoustic Reference Guide, and working closely with sub-contractor, SD Samuels, ROCKWOOL was able to demonstrate the exceptional performance capabilities of its 150mm RAINSCREEN DUO SLAB® insulation product for the hotel development project. As a result, 5200m2 of the BBA (British Board of Agrément) approved A1

rated product was specified as well as ROCKWOOL’s insulation slab, which was installed within the steel frame, providing a complete solution to meet the demands of the specification.

Thanks to its dual-density properties and improved ratio of fibres to trapped air pockets, RAINSCREEN DUO SLAB actually absorbs sound energy as it passes through the facade system. It effectively traps sound waves and dampens vibration to provide an enhanced noise reducing solution in rainscreen applications.

To provide architects and specifiers with complete confidence, the ROCKWOOL RAINSCREEN solution has been accredited by Quiet Mark, which is the independent, international approval award programme associated with the UK Noise Abatement Society charitable foundation. Through scientific testing and assessment, Quiet Mark identifies the quietest products in a given category. As the European Environment Agency report demonstrates, noise has a significant impact of people’s health and the Quiet Mark, along with its new Acoustics Academy, provide architects and designers with a platform to find the right acoustic solutions for every building application area.

Putting the focus on flooring

ROB FIRMAN, TECHNICAL AND SPECIFICATION MANAGER AT POLYFOAM XPS

OFFERS BEST PRACTICE ADVICE WHEN SPECIFYING INSULATION FOR GROUND FLOORS.

During the design of any new build or major refurbishment project, careful attention must be paid to the ground floor insulation specification. As well as contributing to the thermal efficiency of the finished building, it must also provide a durable and robust solution.

The declared thermal conductivity of an insulation product refers to the value that is obtained for 90 per cent of production, with a 90 per cent confidence level. In essence, it is the thermal conductivity of the product when it leaves the factory.

Yet, unlike insulation specified for walls and roofs, the heat loss through a ground floor varies with its size and shape. The soil type the ground floor is built on can also have an impact on the thermal efficiency.

When calculating U-values, current Building Regulations states that methodology in BS EN ISO 13370: 2017 should be followed. This standard uses the ratio of the exposed floor perimeter to the floor area to take account of the variation in heat loss due to floor size and shape. The measurement of the perimeter and area should be to the finished inside surfaces of the perimeter walls that enclose the heated space, however,

un-heated spaces such as porches or garages should be excluded. In the instance where extensions to existing buildings need to be considered, the floor dimensions of the complete building may be taken, including the extension.

Ground bearing floors can include insulation either below or above the concrete slab, and there are factors the designer needs to be aware of when choosing either method.

Where the insulation is below a slab, screed or timber boards for example, the entire load is acting on the insulation. Point loads are spread by the layers above the insulation so that the load acting on the insulation is lower than the load applied to the floor surface.

XPS insulation for example can also be laid directly on the ground, which is an ideal solution for ground floor basement projects which are becoming increasingly popular in the London area as many people are ‘building down’ due to space restrictions to build around the home.

Insulation materials used under slabs, screeds and chipboard should be capable of accommodating the applied loads with the minimum of compression.

The applied floor load acting on the insulation material has two components; the ‘dead load’, which is the weight of the materials laid on the insulation, and the ‘design load’, associated with the use of the floor in the property.

It’s best practice for specifiers refer to the guidance and recommendations contained within BS EN 1990:2002 +A1:2005 and BS EN 1991-1- 1:2002, which should be followed when making sure the insulation is able to accommodate the loads with the minimum amount of compression. The designer must also consider the dynamic loads and how they are applied.

During the design of any building, it’s important to ensure the correct specification of insulation material, and to follow the recommendations of current guidance and Building Regulations.

Liaising with a trusted XPS insulation manufacturer, such as Polyfoam XPS, that offers technical and specification advice during the design stage, will ensure the building performs as per the specification.

Part L Thermal Standards and the Future Homes Standard

A CONSULTATION TO IMPROVE THE CURRENT PART L THERMAL STANDARDS ENDED IN MARCH 2020. THIS CONSULTATION ENCAPSULATED A COMMITMENT THAT, BY 2025, A FUTURE HOMES STANDARD WOULD BE INTRODUCED FOR NEW BUILD HOMES TO BE ‘FUTURE-PROOFED’ WITH LOW CARBON HEATING AND WORLD LEADING LEVELS OF ENERGY EFFICIENCY.

The consultation set out ambitions for achieving the Future Homes Standard, including proposed options to increase the energy efficiency requirements for new homes in 2020 as a meaningful and achievable stepping-stone to the Future Homes Standard. The first stage of a twopart consultation considers proposed changes to building regulations. It also covers the wider impacts of Part L for new homes, including changes to Part F (Ventilation), its associated Approved Document guidance, airtightness and improving ‘as built’ performance of the constructed home.

It is anticipated that an average home built to the Future Homes Standard will have 75-80% less carbon emissions than one built to current energy efficiency requirements (Approved Document L 2013). This is a significant step forward and it is expected that this will be achieved through very high fabric standards and a low carbon heating system. For example, a new home built to the Future Homes Standard might have a heat pump, triple glazing and standards for walls, floors and roofs that significantly limit any heat loss. As in the economy generally, electricity is having something of a renaissance driven by measures that have resulted in a lower decarbonised electricity grid, making electric systems more viable and possibly more capable of helping achieve the energy reductions proposed. Until now, Part L standards have been set based on the CO2 emissions of the dwelling, although this is not a direct measure of energy efficiency. Recognising the progress towards the electricity grid becoming zero carbon, it is proposed to make compliance based on primary energy (kW/h), with carbon emissions becoming a secondary indicator. This is a significant shift that will no doubt require a revaluation of the choice of heating and hot water systems for new dwellings.

The initial Consultation addresses:

• options to uplift standards for Part L of the Building Regulations in 2020; and changes to Part F

• more stringent transitional arrangements for these standards to encourage quicker implementation

• draft outline specification for future consultation about the Future Homes Standard

• clarifying the role of planning authorities in setting energy efficiency standards.

Notably the Consultation sets out two options to uplift energy efficiency standards and requirements:

Option 1: 20% reduction in carbon emissions compared to the current standard for an average home. It is anticipated that this could be delivered by very high fabric standards (typically with triple glazing and minimal heat loss from walls, ceilings and roofs).

Option 2: 31% reduction in carbon emissions compared to the current standard. It is anticipated that this could be delivered based on the installation of carbon-saving technology such as photovoltaic (solar) panels and better fabric standards, though not as high as in option 1 (typically double not triple glazing). Option 2 is the Government’s preferred option as it envisages that it would

deliver more carbon savings and result in lower bills for the householder but has higher build costs.

So how will the proposals impact on the building design and construction? As part of the Governments’ own Impact Assessment, typical dwelling types were analysed with uplifts in the specification of the fabric efficiency and building services to meet the proposed changes. The results are shown in Table 1. Designers can of course vary the specification providing the required reduction in energy efficiency is achieved.

The overall building fabric will have to be improved. For external walls, U-values of 0.15-0.18W/m2K, are assumed for Options 1 and 2 respectively. Current wall U-values for Part L (2013) compliance are typically 0.26W/m2K or below. For masonry walls, this should not dramatically affect the built size of cavity walls when using high performance insulation.

the thickness of ground floor insulation (typically by about 25mm) as well as roofs. The U-values of windows and glazed doors will have to be improved considerably, with overall U-values of 0.8 to 1.2 depending on what option is implemented.

Nordic Copper Rejuvenation

ompleted in October 2019, Hoskins Architects’ award-winning scheme incorporated a complete overhaul of the entire listed, late 19th/early 20th century complex, which consists of The Gallery, Cowdray Hall and War Memorial buildings. Following decades of ad-hoc refits and alterations to the buildings, the design transforms the visitor experience, increases display areas and improves public services. It also gives clarity to the complex, recovering the hidden logic of the original axial planning while enhancing its key spaces.

Copper Extension

The Nordic Brown Light copper rooftop extension contains a suite of environmentally controlled temporary galleries, as well as much-needed learning and event spaces, providing bold new interiors. These new spaces enable the Gallery to hold large international touring exhibitions with their associated events. The extension also facilitates use of two newly created, outdoor rooftop terraces with spectacular views across Aberdeen.

The extension was designed as a sculptural element, responding to the proportions and colours of the existing granite frontages. It is defined by vertical, scalloped panel facades of Nordic Brown Light pre-oxidised copper – a thoroughly contemporary design but sharing materiality with the buildings’ classical copper dome. The Nordic Brown Light copper will also develop naturally over time, responding to the local environment.

Lightweight Construction

The copper panels, including some perforated for transparency, were manufactured by CGL Facades. Nordic Brown Light copper was pressed and rolled to take the scalloped shape, before delivery to site and installation on secret-fix support rails with rose-golden coloured stainless steel cappings. The system forms part of a lightweight construction, minimising extra deadloads onto the existing granite walls below, with steel framing and highly insulated infill.

Copper’s unique architectural qualities are defined by its natural patina, developing gradually in the environment, exemplified by

the Gallery’s original dome. Repairs to the dome itself were carried out using Nordic Green pre-patinated copper, complementing the existing historic patination. This cannot be replicated successfully using other materials with surface coatings but the ‘Nordic Copper’ range provides a wide range of natural surfaces straightaway.

Natural Compounds

The processes involved are generally similar to those taking place over time in the environment, utilising copper mineral compounds, not alien chemical processes. All these surfaces form an integral part of the copper, generally continuing to change over time, and are not lifeless coatings or paint. The Nordic Copper range from Aurubis – part of the world’s leading integrated copper group and largest copper recycler – includes Nordic Standard ‘mill finish’ and Nordic Brown pre-oxidised copper offering lighter or darker shades of brown determined by the thickness of the oxide layer.

The extensive Nordic Blue, Nordic Green and Nordic Turquoise ranges have been developed with properties and colours based on the same brochantite mineralogy found in natural patinas all over the world. As well as the solid patina colours, ‘Living’ surfaces are available for each with other intensities of patina flecks revealing some of the dark oxidised background material. Copper alloys include Nordic Bronze and Nordic Brass, which can also be supplied pre-weathered. The innovative Nordic Royal is an alloy of copper with aluminium and zinc, retaining its golden colour.

A STRIKING CONTEMPORARY ROOFTOP EXTENSION CLAD IN NORDIC BROWN LIGHT COPPER SCALLOPED PANELS ANNOUNCES THE REJUVENATED ABERDEEN ART GALLERY AND REINFORCES COPPER’S HISTORIC PRESENCE ON THE CITY’S CIVIC ROOFSCAPE.

Inside products insight

Copper’s unique architectural qualities are defined by its naturally developing patina, determined by the local environment, which cannot be replicated successfully by other materials using applied coatings. Weathering over time gives a darkening surface colour to copper that can eventually result in the distinctive green or blue patinas seen on older roofs.

“To provide straightaway the brown oxidisation or blue/green patination of copper surfaces, factory-applied surface treatments are popular – particularly for facades where rainwater dwell-time is insufficient,” explains Graeme Bell of Aurubis. “They bring forward the environmental changes without taking away the integrity of copper as a natural, living material.

“Alloys of copper have also grown in popularity with architects. They include Bronze, an alloy of copper and tin which gradually changes to a dark chocolate brown, and Brass, which can also be supplied preweathered. An innovative alloy of copper with aluminium and zinc enjoys a rich, golden through-colour which remains very stable, just developing a matt surface – but no patination – over time.

“Apart from traditionally-jointed, rolled material supported by a substrate, various other forms of copper are increasingly being explored by designers. For example, copper can be supplied in profiled sheets or extremely flat honeycomb panels, pressed to provide

surface textures and modulation, or perforated, expanded or woven as mesh for transparency.

“But there is more to architectural copper than meets the eye, particularly in terms of recyclability, sustainability and long-term performance. Copper architectural products are produced in modern plants with strictly monitored environmental performance and well-established recycling routes. They include high levels of recycled materials – typically 85% or more with scope up to 100%, saving on energy and greenhouse gases, and contributing to the circular economy. As a lightweight and flexible covering in buildings, structural support demands are reduced, resulting in lower carbon and ‘whole of life’ costs.

“Copper’s exceptional longevity – considered in hundreds of years – is due to the patination process which ensures extreme durability without maintenance and resistance to corrosion in virtually any atmospheric conditions. At the end of a building’s life, copper retains a high scrap value can be recycled again and again without any loss of performance or qualities.

“Copper is safe to use and can be worked at any temperature, without becoming brittle in cold weather or deforming in hot weather. It requires no decoration, maintenance or cleaning, saving resources, cleaning chemicals and cost. Its interaction with the environment has been assessed under the European Reach chemical policy and has no classification/restriction.”

TBA Firefly’s passive fire barriers CPD seminar available on-line

PRESENTED BY SECTOR SPECIALISTS, TBA PROTECTIVE TECHNOLOGIES LTD, WHO MANUFACTURE THE FIREFLY™ RANGE OF FLEXIBLE FIRE BARRIERS AT THEIR ROCHDALE FACILITY, HAVE ISSUED THEIR LATEST CPD SEMINAR ON PASSIVE FIRE PROTECTION (PFP) VIA THEIR WEBSITE.

The introduction to the new CPD begins with an overview of PFP, citing the importance of sealing around pipework, ducts and other penetrations. The presentation then moves on to legal requirements, explaining that cavity fire barriers should offer a minimum of 30 minutes’ containment of smoke and flame with the occasional need to perform for longer periods of up to two hours.

A cavity fire barrier also needs to restrict the temperature rise on the unexposed face for a minimum of 15 minutes, but is often specified to deliver 30 minutes or more of insulation. It should also be noted that barriers / compartmentation should be in place every 20 metres.

Various elements of Part B of the Building Regulations are covered, and the CPD points out that the “prime objective of Part B is the safety of life, not the preservation of the building.”

There are various slides showing illustrated examples of the types of detailing required, that good design should consider when deciding upon the specification of a fire barrier: Typical installations include cable tray penetration, joint detailing and timber penetrations.

The seminar then moves on to the importance of PFP components, and provides a variety of photographic examples of real life installations. The presentation is completed by an example of IFC certification and lastly, the summary.

Essentially FIREFLY™ has created a straightforward and instructive presentation, ending with a questionnaire to complete in order to receive a 2 Point CPD accreditation.

Firefly™ Sales Director Martyn Rolfe, comments: “The new CPD seminar on our website offers Architects, Fire Engineers and other specifiers the opportunity to undertake training in their own on crucially important subject of passive fire protection. This will award them two points towards their annual CPD score and we are also developing a video conferencing version of the seminar, so that we can present to multiple people remotely.”

New curved on plan secondary glazing for the Master’s Office

NEW OFFICES OF THE MASTER (CHRIS SMITH, BARON SMITH OF FINSBURY) OF PEMBROKE COLLEGE, HAS BEEN UPGRADED WITH CURVED ON PLAN AND STANDARD SECONDARY GLAZING TO CREATE QUIETER AND WARMER OFFICE ENVIRONMENTS,

IN LINE WITH THE COLLEGE’S OVERALL SUSTAINABILITY PLAN.

Situated in the quintessentially English university city of Cambridge, three neighbouring buildings forming part of Pembroke College’s estate have recently been renovated.

Pleasance Hookham and Nix devised the architectural plans of how the buildings would be reconfigured, to house the Master and staff who were being relocated from the main building. Due to its Listing, the original single pane windows had to be retained, so a solution to combat the noise ingress and thermal inefficiencies had to be sought. Many site visits were held to discuss the window opening preparatory work Coulson Building Group would need to undertake and the best frame styles to suit.

The main view out of the corner of the building on Mill Lane, was an ornate large curved on plan sliding sash. The new Series 25 vertical sliding curved on plan unit, was

deemed to be the best solution as it matched the sightlines of the original perfectly.

Over 60 units were installed throughout the buildings. On the front elevation, where noise ingress was a concern, the secondary glazing was installed with a larger cavity, to create

the sound insulation. On the rear of the building the glazing was mainly for thermal and one intricately etched large window overlooking a flat roof, had a large Secured by Design unit installed for added security.
