PROJECT INSIGHT

A Historic Slate Installation Fit For Leaders Of The World At The G7 Summit

CUPA PIZARRAS has been specified across a major development and refurbishment at Tregenna Castle. The company’s products were selected for their ability to endure extreme local weather and provide an exceptionally long lifespan. Delivering spectacular views of the St Ives coastline, the Castle Approach Estate is a new collection of lodges built in the grounds of the historic Tregenna Castle Resort.

Looking to complete the exclusive lodges, roofing contractor, Summit Roofing Solutions utilised a number of CUPA PIZARRAS’ products. Likewise, the project team also chose to use the company’s natural slate to complete a renovation of Tregenna Castle’s original roof. The lodges and castle are subject to difficult coastal conditions, including extreme winds and sea spray.

As such, the project team needed access to roofing solutions that could deliver long-lasting, durable performance. Likewise, given Tregenna Castle’s status as a Grade II listed property, the team had to ensure that any selected products were able to deliver a traditional aesthetic, whilst still providing modern performance. Fortunately, CUPA PIZARRAS natural slate was able to meet all the desired criteria.

Therefore, roofs on the lodges at Tregenna Estate exclusively used CUPA PIZARRAS’ 400mm x 200mm CUPA 12 natural slates, fixed using 100mm stainless steel hooks that were also produced and supplied by CUPA PIZARRAS.

Notably, Summit Roofing Solutions was able to install the natural slate as a closed mitred hip system. In doing so, the project team ensured that all slates lined up perfectly with one another, which is only possible on account of the products’ uniform size and quality.

This was particularly important on the lodges, where sections of roof were stepped down in certain locations and visible from ground level. Speaking on the project at Tregenna Estate, Adam Palmer, Company Owner of Summit Roofing Solutions commented: “Upon receiving the brief, we recognized that CUPA PIZARRAS’ solutions could help us to meet all key project goals. What’s more, the company helped us to overcome logistical challenges.”

Following project completion, the Tregenna Estate played host to key stakeholders attending the G7 Summit in Cornwall, including the Prime Minister and US President Joe Biden. In anticipation of the event, enhanced security provisions were put in place on the site, which made the logistical side of the project more difficult.

Thankfully, through its extensive distribution network, CUPA PIZARRAS was able to devise a well-considered delivery and logistics plan to ensure that supplies could reach the project team at critical times. CUPA 12 was chosen for this prestigious project as it is a high quality dark grey slate with a smooth finish.

With a life span of more than one hundred years and very little maintenance required, natural slate is a durable, weatherproof product, un-matched by artificial alternatives. CUPA 12 has also received approval from Snowdonia National Park as a Welsh Slate alternative and has been certified by BRE Global as A+ for its quality, transparency, and sustainability credentials. www.cupapizarras.com/uk/

Desirable New Build Reflects Quality With The Choice Of Rainwater System

When it came to self-building a dream home, a couple from Yorkshire wanted the finish to the exterior of their home to convey both modern style and quality with a nod to traditional building materials.

The plot of land was bought with an original property standing on it which was demolished to make way for the tasteful 4-bedroom family residence. Their new home was designed to be in keeping with the more mature properties in the surrounding area but also to include elements that offered a greener more modern way of living with consideration given to energy efficient, durable and ecologically sound building materials. When looking at a rainwater system they wanted all these elements to be reflected together in the choice of gutters and downpipes.

After receiving samples from Yeoman Rainguard they choose the XL Aluminium range which, being manufactured from 3 mm thick extruded aluminium, gave the confidence of a robust and long-lasting system.

Style is also exuded from the XL aluminium range with the 125 x 100 mm MOG XL gutters being installed along side the 75 x 75 mm square downpipes. Finished in an attractive black powder coating which not offers a stunning heritage look but gives the gutters and downpipes protection against the elements leading to 30 years plus, maintenance free, lifecycle.

Yeoman Rainguard manufacturing facilities helped to offer additional benefits to the build by being able to specially design external angles and stop end units in one piece. The units reduce the amount of jointing required therefore limiting the possibility of points of leakage in the gutter run.

A bespoke aluminium Fascia/Soffit was also designed for the new build again adding to the immaculate finish and maintenance free advantages of the property’s exterior.

The Anzeiger-Hochaus in the centre of Hannover, built in 1928 and 51 m high, with its characteristic facade in the style of ‘brick expressionism’, is a unique example of German skyscraper construction. The city’s planetarium was once located under the 17 m high dome, and subsequently the highest cinema in Germany. The 2019 renovation included a completely new Nordic Copper Special Patina dome roof meeting strict listed building protection.

Sustainable Restoration With Nordic Copper

Although considered to be a thoroughly modern material offering limitless possibilities for contemporary architectural design, copper is also – of course – one of our oldest building materials, traditionally covering the domes and spires of city skylines. Nordic Copper Special Patina has been developed specifically to help with repairs, restoration or extensions to historic buildings. Copper’s unique architectural qualities are defined by its naturally changing patina – which cannot be successfully replicated using other materials with surface coatings.

Within a few days of exposure to the atmosphere, a copper surface begins to oxidise, changing from the ‘bright’ mill finish to a chestnut brown, which gradually darkens over several years to a chocolate brown. Continued weathering can then result in development of the distinctive green patina – or blue in coastal locations. This process is an expression of the metal’s propensity to revert to mineral compounds that resemble the ore from which it originally came. Some rainwater is needed for the patina to form and its rate of development will depend on the water “dwell time” on a surface.

As a result, vertical cladding and sheltered surfaces will take much longer to patinate naturally than exposed roofs. Airborne pollution also increases the rate of patination, which therefore takes longer in more remote, cleaner environments than in cities or industrial areas. The complex combination of factors determines the nature and speed of development of patination, giving copper unique, living visual characteristics developing over time in response to local conditions. Natural Surface Treatments - All these naturally developing surfaces can be provided straightaway with the ‘Nordic Copper’ range. The factory processes involved are generally similar to those taking place over time in the environment utilising copper mineral compounds, not alien chemical processes. The surfaces form an integral part of the copper, generally continuing to change over time, and are not lifeless coatings or paint.

The architectural 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. The innovative Nordic Royal is an alloy of copper with aluminium and zinc, retaining its golden colour and simply losing some of its sheen over time with exposure to the atmosphere to give a matt finish.

But of particular interest to architects and conservation specialists working with historic buildings are the extensive Nordic Blue, Nordic Green and Nordic Turquoise ranges. They 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

Individually Developed Special Patinas - Copper’s patina film provides impressive protection against corrosion and can repair itself if damaged, defining the exceptional longevity of copper cladding – counted in hundreds of years.

Suomenlinna Church, built in 1854, is on the Unesco world heritage list as a unique example of military architecture. The presence of the church on the Helsinki skyline is significant and patination of the master tower – which doubles as a lighthouse – particularly important. The new Nordic Copper Special Patina roof does not just resemble the old one but was actually made from recycling the original copper

Suomitalo is a major, unique office building in the heart of Helsinki dating back to 1911. Its complete roofscape has been replaced using Nordic Copper Special Patina to match the original material which has been recycled for new applications.

But repairs and restoration – following substrate or structural failures, or other damage – or extensions to historic copper buildings may still be needed. The Nordic Copper Special Patina system is designed specifically to help architects with restoration projects. Aurubis has several decades of experience of developing unique patinated architectural copper products, successfully applied on historic – including listed – buildings in the UK and abroad. With Nordic Copper Special Patina, unique pre-patinated copper material can be produced to match naturally patinated copper, especially for historic buildings.

An original sample from the building is used but initial development can be started with the help of a Special Patina Tool (which can be downloaded from www. nordiccopper.com and printed). The card is simply placed on the original copper surface and photographed. Once a specific patina mixture has been established and product supplied, the project mix is retained in case of follow-up orders.

100% Recycled Material - Aurubis can also recycle the original copper removed from a project. All of our architectural copper products are manufactured using 100% recycled raw-material. Copper’s ability to be recycled repeatedly, without any loss in performance, is an important sustainability benefit. Aurubis is part of the world’s leading integrated copper group and largest copper recycler. For more information and to read project stories visit: www.nordiccopper.com or email: g.bell@aurubis.com

Meg Makes A Splash!

Located in the foothills of the Franklin Mountains in El Paso in Texas, Camp Cohen is one of three new waterparks designed to celebrate the culture of the city’s diverse communities. Parkhill Architects were appointed by the City Authority to design them and Camp Cohen was the first.

It was decided to use Abet Laminati’s MEG exterior grade laminate for this exciting and creative camp-themed park which includes water slides, a toddler pool, lazy river and more amenities for all ages. MEG was specified as the architects were looking for wood effect cladding which would complement the camp theme and which could be cut into planks to simulate a cabin.

It was also heavy duty enough to cope with the sustained usage and the extremes of sunlight and temperatures which can easily range between -2°C in the winter and 35°C in the summer. As a result, MEG 754 Padouk was seen as the perfect solution. This visual plank look can now also be achieved with the newly-launched and competitively-priced Easy MEG siding product.

Camp Cohen is another example of MEG in action where the need for high performance and durability is married up with low life-cycle costs, aesthetic design and resistance to weathering. The range comprises 58 colours and 29 woodgrains together with 5 concrete and metal effect finishes. MEG is a self-supporting high pressure laminate (HPL) for cladding the exterior of buildings, balconies and other applications.

It features high resistance to temperature, climate shock, weathering, UV light and impact. Samples and technical literature are available from Abet Ltd on tel: 020 7473 6910 or visit uk.abetlaminati.com

MAGPLY FEATURES IN FIRE-FIGHTING ROLE AT SKY STUDIOS ELSTREE

Magply boards are being used as part of Sky’s efforts to create the world’s most sustainable film and TV Studios, Sky Studios Elstree. Currently under construction by main contractor BAM, the build has recently included the use of 9mm thick Magply boards as part of a flat roof build up specified for the product’s proven fire-protection capabilities and allround performance benefits.

The work on the new production buildings is being carried out by London based Waterproofing specialist, Guaranteed Asphalt Ltd. which is installing their BBA Agrement certified hot melt flat roofing system over a reinforced concrete deck with the Magply boards being used to protect the mineral wool insulation. The Magply boards were secured in place over the 300mm thick StoneWool insulation using an adjustable length TIA fixing from the SFS range: drilling down into the concrete substrate. The fixing consists of a mushroom-type plastic sleeve which inserts in the bore hole, followed by a secondary concrete screw that is dropped into the sleeve, which is driven into the deck.

Magply MgO boards present a fire-safe and environmentally friendly alternative to conventional plywood or OSB products. The different thicknesses of panel are also widely used for flooring and pitched roof installations as well as being approved by many different manufacturers of render finishes as a suitable substrate. www.magply.co.uk

Bradite One Can and a local builders’ merchants have helped a small Suffolk village to celebrate the Queen’s Platinum Jubilee. Residents of Thorpe Morieux voted for a giant Union Jack to be painted on the end wall of their village hall.

A design of a flag fluttering in the breeze was worked up by Tony Sheppard, and a team of keen helpers was assembled to take on the task. Then it was off to Kent Blaxill, Bury St Edmunds to seek some paint advice. “Knowing the properties of Bradite One Can … this made it the go-to product for this project,” said the store’s decorative branch manager, Mark Levett.

“After contacting Bradite about the project, they came back with an offer to supply the paints which was very gratefully received by those in Thorpe Morieux.”.

Paint was provided – of course in a colour scheme of red, white and blue – and the community got the job underway, finishing in good time for the festive celebrations. www.bradite.com

A new case study explores recent urban realm regeneration projects in Tottenham, London exemplifying the synergy of concrete block permeable paving and street trees to address climate change while delivering SuDS. It demonstrates important new techniques with permeable surfaces applicable to all urban areas. Completed in 2018, the regeneration of White Hart Lane in north Tottenham, by muf architecture/ art, was a pilot designed using ‘Healthy Streets’ principles.

These aim to create: ‘streets that feel pleasant, safe and attractive. Streets where noise, air pollution, accessibility and lack of seating and shelter are not barriers … streets with seating, shade and greenery, and reduced dominance of vehicles by designing for slower vehicle speeds.’ The project delivers these aspirations and was one of the first to use the ‘Healthy Streets’ indicator as a metric.

Multifunctional Permeable Paving - But it also applies innovative sustainable drainage (SuDS) techniques introduced by design collaborators Robert Bray Associates. This approach reduces flooding and pollution of the hidden Moselle River through the integration of bioretention raingardens to collect and treat polluted road runoff. In addition, extensive concrete block permeable paving (CBPP) surfaces not only act as SuDS elements – attenuating and treating rainwater runoff – but also enable essential air/CO 2 exchange and optimised water supply for tree roots, using a range of techniques. A focal point of the scheme is a new Pocket Park, enabled by relocation of a bus stop and removal of extensive asphalt paving.

The park is separated from the road by bioretention raingardens, intercepting runoff from the whole width of the ‘side-hung’ carriageway which acts as a catchment. It also includes long planters to accommodate mature and new trees, and other green infrastructure, incorporating seating. This also enabled de-paving around a mature but suffocated and asphalt-locked Plane tree. Love Lane, which runs perpendicular to White Hart Lane in front of the new landmark Underground station, is now a concrete block permeable paved, adopted highway.

CBPP can also accept runoff from White Hart Lane and other impermeable surfaces. At two points, structural tree pits span the full width below the road surface connecting road-narrowing tree planters on each side, in readiness for future planting. Based on the ‘Stockholm Solution’ for urban tree planting, the deep structural soil zones form sumps which are hydraulically connected to the coarse graded aggregate sub-base of the permeable paving.

Public Realm Regeneration With Permeable Paving

Healthier Resilient Street Trees - This means that in heavy or prolonged rain, once percolated runoff begins to move laterally along the interface between the sub-base and subgrade, it moves toward the structural tree pits where it begins to be attenuated. Once the pits fill to the level of the base of the road sub-base, the attenuation and infiltration spread out over the whole road zone.

This pattern of flow and attenuation means that trees benefit from rainwater collected from an extended catchment, making them healthier and more resilient to drought. Although initially unfamiliar with the structural tree pits, with support and advice the installation contractors soon became comfortable and are now installing them elsewhere.

At the renovation of Broad Lane Square in south Tottenham, the same designers take forward these principles with further innovations. In particular, ‘inverted raingardens’ protect existing trees and new green infrastructure, supplied with a gradual supply of clean water from extensive CBPP catchments.

Permeable Paving in Harmony with Trees - Concrete block permeable paving and street trees have been proven to work together in synergy. CBPP – whether full-construction with subbase or applied as an overlay on an existing impermeable road base – can collect rainfall away from the canopy and convey it to the tree. It can then simply discharge horizontally into a raingarden, with overflow into existing adapted gulleys. The raingarden stores water during heavy rain for SuDS, retains soil moisture during dry weather and provides additional water quality ‘polishing’, as well as irrigation.

Alternatively, CBPP can be used over standard tree pits, proprietary tree planters, Stockholm System or other structural soil installations, enabling irrigation and simple air/carbon dioxide exchange essential to trees – without additional

reservoirs or pipes. CBPP also avoids tree root disruption common with other paved surfaces. Concrete block permeable paving technology will prove invaluable in delivering the street trees now demanded by planning policies for new developments as well as regeneration.

Structural tree pits connect road-narrowing tree planters on each side, based on the ‘Stockholm Solution’.

CURVED MARMOX MULTIBOARDS FACILITATE CYLINDRICAL FAÇADE FOR KENT PROPERTY

The developer building a private property in the beautiful Kent town of Westerham, near Sevenoaks, has made full use of the flexible version from the Marmox Multiboard range in creating a two storey, drum-shaped elevation that is being finished using a proprietary render system.

While standard Marmox Multiboards are formed from rigid sheets of extruded polystyrene (XPS) faced on both sides with a layer of polymer modified concrete encapsulating glass fibre reinforcement, the Curved version features 2mm wide slices through 75% of their depth, at 20 mm intervals.

This enables the 1250 x 600mm boards to be bent down to radii as tight as 200mm if fixed

so that the slices close together. Even tighter radii can be achieved by folding the boards so that the ‘teeth’ open up.

They can either be fixed against a blockwork of other solid surface using a continuous coating of tile cement or secured to timber battens at 300mm centres using screws and the special Marmox washers. This flexibility makes Curved Multiboards ideal for creating archways, curving partitions and cubicles or even moulded tiled seats. www.marmox.co.uk

STO ACOUSTIC SYSTEM HELPS RESTORE HISTORIC LONDON ART GALLERY

The acoustic performance of a major London landmark building was upgraded using the StoSilent Distance acoustic system. Hayward Gallery at London’s Southbank Centre underwent a complete refurbishment, and the StoSilent Distance system helped create a new and dramatically improved acoustic environment for this worldrenowned art gallery.

The 66 pyramid-shaped skylights which originally featured on the building had become damaged over time, while internally, a series of impractical sound-absorbing baffles and a translucent suspended ceiling had been used below them. The aim was to remove the suspended ceiling, reclaim the original height of the gallery spaces, and allow more natural light to enter. The pyramid roof lights were reconstructed using modern materials, and this meant that reliable acoustic treatment needed to be fitted into the coffer spaces below them in order to create the required acoustic environment.

Unlike conventional acoustic treatments which use exposed grid and tile systems and offer limited design possibilities, the StoSilent Distance solution allows the creation of modern, clean, monolithic and seamless solutions, and can accommodate unusual design features such as the gallery ceiling and its pyramid-shaped skylights. StoSilent Distance was installed in the deep acoustic coffers which sit below each of the pyramid skylights. www.sto.co.uk

MAGPLY BOARDS SHEATH STRUCTURE TO STRATFORD’S SUGAR HOUSE ISLAND SCHOOL

The new Sugar House Island Primary School in Stratford, East London, is making full use of the strength and stability to Magply MgO boards which carry a full set of internationally recognised accreditations, including BDA certification and which are widely specified for their excellent fire performance. Magply offers a fire-safe and environmentally friendly alternative to conventional plywood or OSB products.

Additionally, the unique production process keeps the chloride content to just 0.01%, enhancing both stability and long-term durability. The different thickness of panels is also widely used as a substrate board for the direct application of proprietary render systems, as well as for flooring and flat or pitched roof build-ups. www.magply.co.uk

AFFORDABLE HOUSING GIVEN SUPERIOR VAPOUR BARRIER AND AIRTIGHTNESS SOLUTION

A series of 10 newly built affordable Council houses in Montrose, Scotland has been fitted with a highperforming variable-permeability vapour control layer from the A. Proctor Group. Procheck® Adapt is designed to protect the building fabric from the potential risks of condensation and act as an effective airtight barrier.

Contractor, Andrew Shepherd Construction, proposed the use of the Procheck Adapt available from the A. Proctor Group. Thanks to its unique design, the Procheck Adapt membrane offers variable permeability which adapts to changes in humidity levels and allows the structure to dry out in the summer and in sunny days during spring and autumn while protecting it from moisture overload in the winter. This is possible because the membrane adapts its vapour resistance to the environment i.e., vapour tight in the winter and more vapour open in the summer.

This ensures that the building fabric is protected from damaging moisture levels during cold, wet winter months, and allows the fabric to dry out effectively in warmer, drier months. Procheck Adapt has a translucent structure which eases fixing to structural frames and in combination with its integral tape allows for a fast installation time. Procheck Adapt is suitable for a variety of commercial and residential applications and provides airtightness to the structure as well as vapour control. www.proctorgroup.com

Major Innovative New Solution From The Ever Progressive Schöck

Over six decades Schöck has built a formidable international reputation for innovative and progressive product design. The company is best known for its market leading range of Isokorb structural thermal breaks, but its pioneering reinforcement technology and impact sound insulation solutions are also a significant part of the product portfolio.

Innovation though is not always about original product development. The Schöck philosophy of rethinking existing product capabilities can lead to derivative technology and the new Sconnex product range is a perfect example. It offers outstanding insulation performance, combined with an exceptional load-bearing capacity. Closing the last major thermal bridge - Type W, for insulating the thermal bridge at the base, or the top of the reinforced concrete wall; type P for insulating the column head and eliminating the need for flank insulation; and type M, a capillary barrier that insulates at the base, or the top, of a masonry wall.

With these ingenious high quality solutions, the company has transferred its Isokorb expertise in balcony technology to walls and columns. But what necessary development steps and which building physics obstacles had to be overcome for the concept to become an approved component?

Building physics and expert analysis - The main focus of the 2050 building policy guidelines is to reduce energy losses and a critical area is the thermal performance of the building envelope, through a fabric first approach.

Sconnex contributes significantly to meeting such a challenging and vital sustainable concept. About 40% of all thermal bridges in a building are caused by walls and columns, resulting in around 10% of heating energy losses. So the objective was to be the first company to develop a component for wall and column connections that both minimises thermal bridges and makes external insulation unnecessary.

However, bringing a major new product to market requires extensive due diligence. First, building physics analysis confirmed the solution as being realistic in its practical implementation. Then, extensive expert opinions were prepared for the German Institute for Construction Technology (DIBt), where all mandatory legal requirements, including 90 minute fire resistance, were met. Because of the variance from practiced construction methods, Schöck also involved scientists from the University of Darmstadt.

With groundbreaking innovations, Schöck often teams with specialists from universities and high-profile engineering firms in the development of calculation models. In one dissertation, an empirical design proposal was created for the application of the connection element in construction practice, based on extensive experimental studies on its load-bearing behaviour. Schöck test results were also incorporated and the design proposal ratified by expert opinion.

Total assurance for architects and planners - By introducing Sconnex, Schöck has met the needs of the construction industry in maximising the reduction of thermal bridges involving walls and columns. Architects and planners can be assured that the Sconnex product family sets new standards for energyefficient construction in the 21st century; and those who have already incorporated the products into their projects are enthusiastic about the new design freedom, the planning safety and the economically achievable results for the client. www.schoeck.com All three product types

Sto’s External Wall Insulation System And High-Performance Façade Paint Help Bring New Innovation Studio To Life

A new state-of-the-art business incubation building in Dorset has been completed with the use of an integrated package of Sto thermal insulation and external render and paint products. The company’s StoTherm Vario and StoTherm Classic insulation systems were specified for the new Innovation Studio at the Arts University Bournemouth, along with StoSilco exterior render and StoColor Dryonic façade paint.

The new Innovation Studio now provides a base for digital and creative start-up businesses, providing support with their research, innovation and development initiatives. “This is an important building, part-funded by the Dorset LEP,” explains Tim Culverhouse of project architects, CRAB Studio. “It needed to combine a very specific mix of internal facilities with a modern, dramatic, external appearance that reflected the creative nature of the occupants.” The cost-effective StoTherm Vario system installed onto this unique two-storey building has an efficient single-leaf construction that provides excellent thermal performance whilst also protecting the external wall surface from weathering.

A mineral bonding and reinforcing mortar was used to adhesively fix the insulation to the cement particle boards and lightweight steel frame, and the system was able to accommodate the curved substrates which feature in the building’s design. Although an alternative insulation system was originally considered, it was decided that Sto solutions could provide the same thermal performance, but also deliver cost benefits.

StoTherm Classic K insulation was also specified for certain parts of the building. “We needed a different solution for some areas,” adds Tim Culverhouse. “These sections carry painted murals, and we wanted those to extend right down to the bottom of the walls, so the insulation had to extend down below the damp-proof course."

"The StoTherm Classic K was perfect for this. It didn’t require any additional expansion joints, and so created a smooth surface onto which the murals could eventually be added. The murals now appear to ‘flow’ down into the ground and create a striking visual effect.”

A reinforcing coat with embedded reinforcing mesh was applied to the insulation, followed by the StoSilco K1.0 silicone resin render, to add extra protection. This genuine silicone resin-based render is robust, durable and provides a very high

degree of CO2 and water vapour permeability, to reduce the risk of interstitial condensation. The overall external façade system was completed with the application of Sto’s innovative StoColor Dryonic façade paint in yellow and orange shades.

This unique paint uses principles borrowed from nature to create a surface which simultaneously repels water and channels it away, to encourage the surface to dry more rapidly and protect against the growth of algae and unsightly staining. The façade will look exactly the way the architect had planned, and will go on looking that way for many years to come, with far less maintenance than any conventional alternative would require. www.sto.uk

Cupa Pizarras Supplies Contemporary Rainscreen Cladding Solution For Impressive London Home

CUPA PIZARRAS has been heavily involved in the development of a new self-build residential property in North West London. The manufacturer was initially approached due to its range of natural slate façade designs, with its CUPACLAD® 201 Vanguard system eventually specified to create an impressive and striking façade. Located in Dollis Hill, the property is situated next to a housing estate and opposite an existing slate clad façade, while views to the rear give the illusion of a peaceful woodland setting.

The designers sought to create a family home with a high-end exterior finish that felt like an escape from London, while also working well with the surrounding structures. Early on, natural slate was identified as a material that could help to create an attractive contemporary façade around the rear, sides and the upper elevation of the front of the property. It was also crucial that the façade would act as a rainscreen cladding system so the project team approached CUPA PIZARRAS about its CUPACLAD® natural slate rainscreen cladding.

The project team visited Taylor Maxwell’s London Bridge showroom – the exclusive distributor of CUPACLAD® in the UK - to discuss options with the Taylor Maxwell and CUPA PIZARRAS teams as well as view a CUPACLAD® sample wall. This session helped to establish that the CUPACLAD® 201 Vanguard system was the ideal solution. A fully BBA approved system, CUPACLAD® 201 Vanguard is 100% non-combustible and offers a lifespan of over 100 years. Following the initial consultation, CUPA PIZARRAS worked closely with the project team, including carrying out a number of site visits.

The use of CUPACLAD® 201 Vanguard was kept in mind throughout the design process, with the dimensions of the slate determining the placement of windows, vents and corners. This meant that when it came to construction, it was a simple installation process with minimal wastage and resulting in a clean finish.

The CUPACLAD® 201 Vanguard system is constructed from horizontal aluminium profiles, mechanically fastened to an aluminium sub frame support. Once fixed in place, the rows of natural slate are clipped on, and in the case of the Dollis Hill property, using visible fixings to create an attractive pinstripe effect. “The product looks fantastic in-situ on this project,” commented Tom Ward, Cladding Product Advisor at Taylor Maxwell.

“The dark grey slate rainscreen cladding provides a striking colour contrast with the refurbished light brown timber fencing and complements the property’s black aluminium windows and glazing.” www.cupapizarras.com/uk/

Crittall Windows – I’ll Drink To That!

A Cornish brewery has moved into renovated premises that give visitors a whole new experience of watching the creation of their favourite beers with Crittall Windows playing a crucial role in the new concept.

Verdant Brewery took over a rundown warehouse on a Penryn industrial estate and, in addition to installing the brewing vats, created 400 sq. metres for staff offices and a space for public use, dubbed the Taproom.

The new interior was created around a steelframed installation with Crittall Corporate W20 windows providing a light and contemporary area where visitors can have a beer and something to eat while enjoying views through to the working brewery, a paramount consideration of the client.

In addition, The Taproom provides a mezzanine balcony overlooking an area that can also be used for entertainment from a DJ or with live music. The design was produced by locallybased architects Zelah Studio.

Said architect James Collins; “We used the W20 system as it allowed great flexibility and a quality industrial look that the client wanted. Large expanses of the glazing allowed us to create views of the brewery from all spaces.” www.crittall-windows.co.uk

LANDMARK LEWISHAM PROJECT USING A1 MAGPLY FOR FIREPROOF PATTRESS INSERTS

A significant new high-rise residential project in the London Borough of Lewisham is being built to provide high quality social housing, with the design of the structure prioritising the use of non-combustible materials: including the choice of A1 rated Magply boards for pattresses within the external walls.

The development at Creekside in Deptford is being built to create a total of 56 one, two and three bedroom apartments, including three specially equipped units on the lower levels of one block for those with mobility issues. Within all of the high specification homes, pattress blocks cut from 18mm sheets of Magply boards are being fitted to the reinforced concrete structure’s infill of heavy gauge steel studs.

The pattresses are being positioned to support kitchen cupboards and bathroom units as well as radiators throughout the eight and 10 storey buildings. Independently certified to offer a range of performance benefits. Magply MOS boards present a fire-safe and environmentally friendly alternative to conventional plywood or OSB products which normally only offer a Euroclass D or E rating. Importantly the pull-out strength for 18mm Magply is in the range 3.45-4.00 Kn/m2. www.magply.co.uk

OFFICE REFURB SPECIALIST UPGRADING FIRE PERFORMANCE USING TBA FIREFLYTM RANGE

A high specification office building close to Manchester Airport has been subject to a series of planned refurbishment contracts, with the phased work including the upgrade of each floor or unit’s fire performance using smoke and flame barriers from the range of TBA FIREFLYTM. Owned by Orbit Developments – part of the Emerson Group - Park Square is a modern commercial office building offering up to 65,000 sq ft of space over five floors.

As leases of various occupants expire, the Group’s fit-out contractor, Kirkham, strips out and refurbishes the vacated spaces, including installing TBA’s Phoenix barriers above the suspended ceiling grids before fitting new panels and improved lighting.

TBA FIREFLYTM Phoenix is a lightweight smoke and flame barrier developed to enable compartmentation within buildings to provide up to 120 minutes integrity under BS476 Parts 20 & 22. Certified by IFCC the flexible and straightforward to install material I is suitable for both newbuild and retrofit situations.

Hauraton Channels Drain Blue Badge Scheme Parking Bays At RHS Wisley

The first phase of The Welcome Building and surrounding landscape at Royal Horticultural Society gardens, Wisley, Surrey has transformed the experience for visitors to the gardens with buildings including a spacious arrivals hall, café, shop, plant centre and a 100 seat restaurant. There are now three large car/coach parks including Blue Badge scheme easy access bays for visitors in park two.

One hundred metres of Hauraton RECYFIX® PRO 100 channel system, fitted with FIBRETEC® C250, 9mm HEELSAFE slot gratings, was used by groundwork subcontractor GPB Construction Ltd to drain the asphalted Blue Badge parking bays for visitors. The channels were installed between the bays and the path leading to the entrance of the new arrivals hall.

The material, PA-GF used to make the FIBRETEC® grating, was especially developed by Hauraton; the tough, UV resistant, fibre reinforced moulding offers high stability and huge strength for its weight. Complying with loading category Class C250 (BSEN 1433) the grating can easily take the weight of cars and commercial delivery vehicles.

The design is a real innovation as its non-corrosive material provides a visually appealing surface finish that retains its black colour. The FIBRETEC® C250 HEELSAFE slot grating was specifically designed by Hauraton R&D engineers to enhance the flow of water into the channel. The slots are super smooth, elliptical openings with the moulded bars having slightly raised triangular bosses along their outside edges.

As well as providing an elegant appearance, the feature ensures surface water is directed into the slots. This configuration also helps eliminate any cross-flow over the grating.

The RECYFIX® PRO 100 channel component is made from 100% recycled polypropylene (PP). The six sizes offered are 160mm wide and range in height from 75mm to 250mm with the FIBRETEC® grating factory fitted on all models. As the largest unit is only 5.8kg, the channelling is easily handled and quickly installed on site. www.drainage-projects.co.uk

The Sky Is The Limit For The Riverside Museum, Glasgow, With The Help Of Bilco UK

Housing the Glasgow Museum of Transport, one of the UK’s foremost transport and technology collections, the Riverside Museum reflects Glasgow’s historic role as a centre of shipbuilding, train manufacturing and engineering. Previously located in a former tram depot on the Glasgow South Side, the Transport Museum’s exhibits have moved to The Riverside Museum, designed by renowned architect, Zaha Hadid.

The museum’s iconic and beautiful design dominates its riverside location, whilst paying homage to the heritage of its surroundings. Crucial to the museum’s flowing design is its roof, which curves and undulates and continues around the east and west sides of the building to constitute the majority of the external structure. Silver-grey zinc panels complete the effect, placing the building firmly in the context of the River Clyde.

As part of the roof construction, Bilco UK was commissioned to manufacture and supply a E-50TB Roof Access Hatch, in addition to two ESW-50REM Smoke Vents, to meet strict requirements for convenient access and building safety regulations. Both the roof access hatch and smoke vents were custom-designed to unique specifications by Bilco UK’s in house team and clad in zinc to create a seamless, aesthetic finish with the museum’s distinctive roof. Expertly engineered to meet the requirements of Manual Handling Regulations, the E-50TB Roof Access Hatch allows for regular and convenient maintenance by facilitating easy one-handed operation.

The Access Hatch will enable engineers with small tools to safely access the roof to conduct essential maintenance, whilst its overlapping cover design, fully welded corners and insulated cover ensure both weather tightness and energy efficiency to deliver the highest standards of longevity for the museum.

Specified to ensure strict adherence with relevant fire safety regulations, the two ESW-50REM Smoke Vents open to 140 degrees in the event of a fire within 60 seconds, guaranteeing the highest standards in fire safety and allowing for the venting of smoke, heat and noxious gases in the event of a fire. Open to Glasgow to the North and the Clyde to the South, the museum’s interior is complex, inviting visitors to snake their way around the various exhibits. www.bilcouk.co.uk

Howe Green On The Right Track With Crossrail Contractor, DMC Contracts

As Europe’s largest current infrastructure project, spanning over 60 miles via 41 different stations, the Elizabeth line will transform rail transport for London, with annual expected passenger levels reaching 200 million. The landmark project has seen the construction of 42km of new tunnels and the development of 10 new stations, with 31 existing stations also undergoing extensive upgrades.

As part of the formation of the central line, which spans from Westbourne Park to Plumstead and Pudding Mill Lane, official Crossrail contractor and one of the UK’s leading fit-out contractors, DMC Contracts, has installed over 1,500 Howe Green Floor Access Covers throughout seven stations. This includes Whitechapel, Farringdon, Paddington, Bond Street, West Ealing, Ealing Broadway and Acton Mainline, where over the last five years DMC Contract’s team of engineers have also installed over 30,000 square metres of Terrazzo and Granazzo floor tiles.

Howe Green’s 7500 Series stainless steel Floor Access Covers have been installed throughout the ticket halls, walkways and main concourses of each station to provide engineers with secure and concealed access to under-floor services, whilst the tamper proof construction also prevents unauthorised access. This is due to the cover’s unique design, which features unobtrusive barrel cover lifting points that can only be accessed with specific lifting and securing keys. As only the securing bolt and barrel edge are visible, the covers provide the highest standards of security, without impacting on the overall design scheme or presenting a potential trip hazard.

Manufactured to BS 476: Part 22, the 7500 Series provides resistance to fire and smoke for up to two hours, providing the highest standards in safety, performance and compliance throughout all seven stations. With each floor access cover withstanding up to five tonne pneumatic tyre wheel loads, the 7500 Series was also supplied in a range of configurations, including singles, multiparts and ducts, to provide unobstructed access to rodding points and winch systems and electrical pits throughout all areas of the stations.

As the lifting blocks are anchored to the inner frame, the floor access covers can be handled easily and safely by contractors, reducing any potential disruption to passenger’s travel as the maintenance can be conducted quickly and safely. www.howegreen.com

High Praise For SureSet Walkways At Chapel Riverside

Located on the River Itchen, sits Chapel Riverside, where a new housing development started in 2017. There are six phases to include 457 new homes which will be built near to the Ocean Cruise terminal. The project was approved by Southampton City Council and is now into the third phase comprising of 132 apartments, all with allocated parking and premium specifications that run alongside the Solent Sea Wall.

Southampton City Council had a clear vision of what they wanted to achieve and were determined to have the whole walkway paved in the most economic, cost effective, durable and aesthetically pleasing product possible. They appointed multi award–winning specialist housebuilder and brownfield developer Inland Homes as main contractor. SureSet were contacted by Kain Dear, the Senior Site Manager from Inland Homes, to attend a pre contract meeting. SureSet were able to provide the requested large resin bound sample panels with various colour options so they could view the paving against the Sea Wall and determine the best appearance.

The SureSet team was also able to discuss the benefits of the products, installation methods and advise on the suitability that the resin bound paving would offer to the walkways. One of the seven key areas in this project was to re-shape the landscapes of the city.

To achieve a consistent aesthetic across the phases of Chapel Riverside Developments, the same materials were to be used throughout.

The colour chosen was 6mm Butterscotch, a permeable resin bound paving material from SureSet's Natural Aggregate range, installed at an 18mm depth. This product was laid to create a desirable waterfront, and due to the smooth nature of the compacted surface, it is suitable for the moderate to high foot traffic and accessible pathways. The area was built above ground level for the apartments and accompanying landscapes to improve ground floor access and create new walkways around the buildings to ensure everyone can enjoy the views.

The work Inland Homes have achieved will further promote investment in Southampton. The 360m2 resin bound paving installation was completed over two days, the asphalt and concrete areas were quality checked and dip tested prior to installation. SureSet ensure that their bases are prepared to safeguard longevity. These pathways were no exception and using a primer and crack reduction membrane over the concrete areas will minimise movement cracks.

A sleek stainless steel edging, supplied by Dural Ltd, was carefully secured to the areas as advised on the plans provided. SureSet's installation comprised various methods. The first was to level out the resin bound material by batch - this was efficiently compacted by using mechanical power floating, and the edges were finished by more traditional hand floating. The SureSet paving looks clean and smooth having the added benefits being low maintenance and permeable. Chapel Riverside has a mix of building types and has been transformed with a new public piazza with cafes, restaurants and shops as well as spaces for retained and enhanced marine industry and activities.

The resin bound walkways are surrounded by green lawns, and seating areas to soak up the views. The 300m stretch of river flood defences, and the reconstruction of a new underground surface water storage tank for Southern Water also makes for an economical build.

Chapel Riverside in Southampton is already a home for many residents and is seen to be a new destination for modern waterside living, and an integral grand plan for economic growth and development within Southampton City.

MARMOX THERMOBLOCKS CUTTING CARBON FOR SOCIAL HOUSING RESIDENTS

Work is well underway on the first phase of an affordable housing project for Somerset West and Taunton Council, where the use of Marmox Thermoblocks was put forward by specialist developer, Equans Regeneration which is leading the work on the site in Taunton. Phase A of North Taunton Woolaway Project will see the construction of 47 new one, two and three bedroom properties with energy saving and the reduction of environmental impact both being given full consideration.

The issue of thermal bridging, in particular, is being addressed through the decision to utilise the highly insulating Thermoblocks around the perimeter of the ground floor slabs. With over 200 homes to be built in the next few years, the total number of Thermoblocks required will run into the thousands. Each length of Thermoblock is comprised of ultra-high performance XPS insulation, encapsulating miniature epoxy concrete columns, while the top and bottom are covered by alkali resistant glass-fibre mesh, retaining a surface of fibre reinforced polymer concrete to facilitate bonding.

The concrete columns have a very low conductivity, so do not present thermal bridges themselves and when coupled with the highly insulating XPS insulation core, a combined thermal conductivity of 0.47W/mK is achieved. Crucially, being able to employ a defined, very low thermal transmittance – derived by thermal modelling or measurement – offers a far more advantageous result than adopting the ‘default’ figure offered in SAP, which can often result in non-compliance under Part L. www.marmox.co.uk

FIREFLY™ APOLLO LITE CREATING HALF HOUR FIRE BARRIERS IN NEW RESEARCH BUILDING

A specialist contractor undertaking all of the fireproofing within a new medical research building in Surrey has been making use of two well proven, flexible fire barrier products from the TBA’s FIREFLY™ range, to provide 30 minutes protection within the majority of the ceiling voids throughout the four-storey structure. CLM Fireproofing has established a reputation as a leader in the fields of both passive fire protection and fire-stopping. CLM is employing Apollo Lite and the Collaroll product in tandem to protect the ceiling voids. The spaces which typically house pipework, power cables and air conditioning units above the suspended ceiling grid, are provided with 30 minutes integrity and insulation through the installation of the flexible Apollo Lite barrier.

The Apollo Lite 30/30 has been developed for use in vertical separation or compartmentation situations, offering both 30 minutes integrity and insulation, thereby exceeding the minimum requirements of the Building Regulations. It is widely specified to form fire barriers within roof voids in many different property types.The flexible woven material is easy to cut and fix and is chemically treated to improve its cooling properties, and therefore prevent temperatures rising in adjoining areas.

Yeoman Rainguard Crowning Glory On High End Development

Property developers Golden Eye Group, augmented their latest residential development with a high-end exterior finish incorporating a rainwater system from Yeoman Rainguard. With a mantra of “a quality finish that will stand the test of time” Golden Eye ensured that quality was reflected not only internally but for all parts of the external building envelope too.

As part of the function and design criteria of the house façade, Yeoman Rainguard were able to provide a sophisticated, quality rainwater system to fulfil technical and aesthetic requirements. To dovetail into the contemporary look, Yeoman Rainguard SL Aluminium gutters and downpipes were chosen. The 75 x 75 mm flush-fit SL Aluminium downpipes provided a modern clean line coupled with 125 x 100 mm MOG gutter. Aluminium Fascia and Soffits from Yeoman Rainguard’s new Squareline range were fitted to complement the sleek lines.

All were finished in a smooth RAL 7022 Grey colour to perfectly match the shade of the windows and doors. The aluminium products give a hardwearing, maintenance free lifecycle of 30 years or more, making this recyclable material both an ecologically and economically sound choice. The rainwater system was installed by Yeoman Rainguard’s experienced installer, ensuring the perfect finish. www.rainguard.co.uk

Hauraton Drainage Systems At Bonus Arena - Hull Venue

Built on brown-field land located on the edge of the main shopping district in Hull and adjacent to Princes Quay, the Bonus Arena – Hull Venue and its associated multi storey car park were opened in August 2018. The £36 million development progresses the legacy of the social and economic impact generated by Hull’s 2017 UK City of Culture status. The Arena, designed by AFL Architects, is a state-of-the-art music and events complex with a flexible capacity of up to 3,500 people. The facility can provide a venue for concerts or corporate conferences in an 800 seat auditorium.

A 2000m adaptable space can be utilised for sporting events or exhibitions and trade shows. Surrounding the Bonus Arena is a public realm laid with grey stone paving and landscaped by reform Landscape Architecture Limited with trees, lawns, flowerbeds and permanent stone seating. An effective surface water drainage system was essential to ensure all weather access to the venue. 140 metres of Hauraton RECYFIX® PRO 100 channels with FIBRETEC® heel-safe gratings were chosen for the job which blended well with the stone paving and would resist damage from applied grit rock salt in freezing weather. The material, PA-GF used to make the FIBRETEC® grating, was specially developed by Hauraton; the tough, UV resistant, fibre reinforced moulding offers high stability and huge strength for its weight. Complying with loading category Class C250 (BSEN 1433) the grating can easily take the weight of commercial delivery vehicles.

The design is a real innovation as its noncorrosive material provides a visually appealing surface finish that retains its colour. The slots are super smooth, elliptical openings with the moulded bars having slightly raised triangular bosses along their outside edges. As well as providing an elegant appearance, the feature ensures surface water is directed into the slots. The RECYFIX® channel component is made from 100% recycled PP. The PRO 100 model is factory fitted with the FIBRETEC® grating and only weighs 4.6kg, so the unit was easy to handle and quickly installed on site. www.drainage-projects.co.uk

CUT-TO-FALLS MULTIBOARD HELPS DRAIN TOP FLOOR BALCONY

An experienced builder and roofing contractor has made use of some 300 standard and tapered Marmox Multiboards to complete a complex refurbishment of a large, top floor balcony on an apartment building in North London. Lightwood Construction carries out work for mainly residential clients right across the capital and has used Marmox Multiboards on many occasions in the past for both interior and exterior applications.

In this instance, long term exposure to the weather and ponding had caused the original waterproofing system to deteriorate, and leaks to occur. Having stripped off all of the rotten felt and boarding, Lightwood Construction’s operatives installed 90 sheets of 20mm thick standard Multiboards, along with 200 of the cutto-falls variant enabling subtle gradients to be created in draining the balcony to multiple outlets.

Equally suitable for wet room applications, Marmox’s Sloping Boards are made from the same waterproofing products as Multiboard - thermally insulating XPS sandwiched between two layers of Marmox’s patented polymer-concrete. The boards have undergone rigorous tests to ensure they are suitable for external use so can be used on the most exposed balconies, as well as inside a wet room. The board is produced in just one size, 1200 x 1200mm, with the edge thickness tapering from 33mm down to 10mm at the opposite side. They can be combined with layers of 20mm thick Marmox Multiboard to extend the slope indefinitely. www.marmox.co.uk
