Latest innovations and products in the building fabric section of the construction industry.

Tower Bridge Magistrates’ Court and Police Station has been reinvented as a four-star boutique hotel in a Dominvs Group development. It includes the installation of a tapered roof insulation system from Kingspan Insulation — ensuring the only thing taking the fall from now on at the former court will be the rain.

Consarc Design Group led the architectural restoration work on The Dixon, named after the building’s original architect, John Dixon Butler. Dexter Moren Associates oversaw the planning stage design, including the construction of a new-build extension. The 193-bedroom hotel has joined Marriott International’s Autograph Collection and also includes a bar, restaurant, two meeting spaces and a gym. The interior décor blends Edwardian influences with modern styles, reflective of the diversity and rich culture of SE1.

McAleer & Rushe have undertaken construction and refurbishment work on the historic site. The completed hotel is expected to achieve a ‘Very Good’ rating under the BREEAM 2014 New Construction Non-Domestic Building standard, with the new extension designed to achieve the 40% improvement in ADL2A criterion required by the London Plan. To raise the thermal performance of the building’s flat roof, whilst also providing effective drainage, Kingspan Thermataper TT47 LPC/FM and Kingspan Thermaroof TR27 LPC/FM were installed.

Kingspan Thermataper TT47 LPC/FM provided the project team with a fast-track alternative to other drainage methods, such as structural falls. The product combines high performance insulation and drainage in a single board which can be fixed with a dry installation process, avoiding the time lost waiting for wet trades to dry. The lightweight boards can also be as little as 1.5%, or less, of the weight of a screed to fall solution, minimising the structural support requirements for the roof surface.

Kingspan Insulation’s specialist tapered roofing service team created a carefully tailored scheme layout for the hotel roof, maximising cost efficiency whilst also ensuring the surface met the rainwater runoff and insulation requirements. The layout also simplified the installation process for the site team aided by the pre-mitred hip and valley boards supplied as part of the Kingspan Thermataper system.

Kingspan Thermataper TT47 LPC/FM and Thermaroof TR27 LPC/FM feature a high-performance core capable of achieving thermal conductivities as low as 0.024 W/m·K. The products, produced at Kingspan Insulation’s Pembridge manufacturing facility, have been successfully tested to LPS 1181: Part 1 and are certified as achieving Class 1 Insulated Steel Deck Pass to Factory Mutual Research Standard 4470: 2016.

Cembrit HD (heavy duty) board has recently been installed in the newly redeveloped East Stand at Twickenham, the home of England Rugby. Resilient, hard wearing and with an impressive fire rating, HD is an ideal multi-use board for high traffic areas in sports stadia such as Twickenham, which on match days sees 82,000 fans descend on the stadium.

The new East Stand development is a stunning, world class facility. KSS was the lead designer and architect on the project and worked with Wildfire London on the interior design concept and delivery. The expanded East Stand offers six floors of stylish event space, including eight brand new facilities delivering a bespoke hospitality experience for fans. The British Airways Rose Garden is the new elegant roof terrace on Level 5 and has been designed for a fun and immersive experience. Hugely popular due to its ‘outdoors feel’ which includes a built-in pizza oven and rotisserie, the venue sees a lots of foot traffic on match days.

Supplied by the Hayes branch of Minster, the fast-growing specialist insulation and dry lining distributor, the Cembrit HD board is installed in the Rose Garden itself, in the wings of the facility, as well as on the walls of the adjacent L5 concourse where impact resistance was important as crowds are moving in confined spaces. A lot of the wall finishes in the Rose Garden are also fixed through the Cembrit boards, including the brick slips behind the rotisserie section. Cembrit was delighted to be involved in the project and chosen by KSS, and Kenji Ikegaya, an architect at the practice, comments: “Cembrit’s robust and weather resistant HD boards provided us with flexibility and multipurpose utility in meeting the complex project requirements. Their technical advisors were also helpful and informative in pursuing the goals of the project.”

Cembrit HD (Heavy Duty) is a Class A2-s2, d0 fire rated high density building board comprising cement, cellulose and mineral fillers. It is ideal for ‘sealing’ buildings under construction as it is impact resistant and can be left exposed without additional treatment. HD is also extremely versatile and can be used as partitioning and is popular in offsite and SIPS construction as well as internal applications.

Dave Newton of Brio looks at developments and trends in exterior and interior door openings

With such a high demand for internal and external bi-folding and straight sliding doors in both domestic and commercial settings many architects are continually challenging themselves to come up with designs that are getting ever closer to the ‘cutting edge’.

According to David Newton, General Manager at Brio UK, that means manufacturers of sliding and bi-folding door architectural hardware need to keep pace, if not outstrip, the architect’s need for creating innovative product that can transform anything they design on paper into reality.

Newton explains: “At one end of the scale there is a call for glass doors with ceiling inset runners that that give the appearance of the door floating elegantly in the space – creating a physical yet ephemeral acoustic barrier – while at the other end there is demand for a rustic, even industrial, robustness that makes a feature out of fixings on barn-like partitions, where they actually become an integral part of the design. And, of course there is still a need for sliding and bi-folding doors of wood, aluminium and composite materials, with or without glass, that make the most of the available light while offering variety in how the space is used.”

Basically, the options open to architects when designing doors and windows are wood, steel/aluminium, composite and glass – or a combination of those. But what architectural hardware is best suited to the job of moving the finished product?

According to Newton this is where a good working partnership with a quality solution provider really pays off for architects. A leading architectural hardware manufacturer with a large range of fixings for all types of door creates a whole world of choice, and one that goes the extra mile for customers, takes on specification for them and is prepared to be flexible makes things a whole lot easier too.

Architects need a manufacturer partner which will ensure the correct architectural hardware is supplied. We work in partnership with the marketplace and are dedicated to producing bespoke, made to measure quality products.

He cites a project undertaken by a joinery firm commissioned to make sliding doors for a leisure centre according to the architect’s specifications and deliver the wood, facias and trim to site for the contractor’s joiners to assemble there. The area taken up by the sliding doors exceeded 13 metres and bought in 10 x 1in boards and laminated them together to make each 63mm door. They made their own oak laminate because, although there is ready laminated product, it is only 3-4ft in length, which was no good for that project. The doors were supplied to site with Brio Stainless Steel Timberoll sliding door gear teamed with Timberoll Brass tracks. This was the ideal combination for the area and the doors work beautifully, gliding effortlessly with just a fingertip push.

The creation of Zero Clearance Glass by Brio was in response to a need for recessed ceiling fittings for ‘floating’ glass doors and it’s not just top and bottom gear that needs to be innovative and fit for purpose. Locking mechanisms and hinges are all part of the complete package and they have to be top standard too. Brio never stops innovating. For example, the 286 Dual Point Lock for Weatherfold 4s with timber or aluminium panels has been developed as an optional for alternative to using flush bolts on panels. Aesthetically it’s better on the eye, as well as being easier to operate, as there is no bending down or reaching up to lock or unlocks the door which is the downside of flush bolts. This makes it very friendly with regards to disabled access.

At the end of the day, door hardware needs to be aesthetically pleasing, durable and reasonably priced. Architects and specifiers will always demand products that tick many boxes – visual appearance is important, as well as durability of the product but in the main they will be looking for a product that looks good, and, can also offer years of trouble-free use. This is true whatever the material they are made from.

Brio is a global company focused on bringing adventurous ideas to life, converting the conceptual thoughts of our customers into exciting reality. I sincerely believe the Brio range of quality, well designed product combined with expert technical resources makes us a world leader in design and quality.

Langley Waterproofing Systems Ltd is leading the way with its new hand applied Cold Polyurea liquid waterproofing system. For use on flat roofs, balconies and walkways, Cold Polyurea is a quick to install, fast curing and durable solution.

Cold Polyurea is an advanced, wet on wet, fully reinforced liquid waterproofing system – and the latest addition to Langley’s range of flame-free, cold applied liquid waterproofing systems. It is flexible and suitable for a number of applications; it can be used in both the refurbishment and new build sectors and is suitable for flat roofs, balconies and walkways.

Cold Polyurea is one of the fastest curing systems on the market – within just three hours of being installed, the roof can withstand foot traffic. Its fast application means installers are on site for less time, reducing disruption to the building and its occupants, as well as the client.

Langley’s new system is available for roofs, walkways and balconies and can be installed utilising an insulated or un-insulated system. For roof installations, Cold Polyurea includes a UV stable sealer coat, to protect the roof from sun damage and prolong its life-span. When installing on walkways and balconies, the sealer coat of the Cold Polyurea is UV stable and slip-inhibiting, to improve the safety of those accessing the area.

Dean Wincott, Managing Director of Langley Waterproofing Systems Ltd, said: “One of the major benefits of Cold Polyurea is its versatility – with a variety of supporting products, as well as different colour options, it can be specified for a wide range of projects. Price point is also a key factor and the combination of this, including a faster curing time, allows the Cold Polyurea products to be a market leading waterproofing system.

“Here at Langley, we recognise that fast application is also a key consideration for installers, which is why Cold Polyurea can be applied and cure within just one day, depending on the size of the work area. We feel this is a real benefit within the refurbishment sector, particularly when applied to balconies and walkways to occupied dwellings. The ability to install without the use of heat or flame, also offers safe installation for those on site, as well as building occupants.”

The new Langley Cold Polyurea system is classified with a Broof(t4) fire rating, which independently tests for the external spread of fire under the Building Regulations, meaning it is unrestricted on where it can be used on a roof. It is fully BBA certified and meets NHBC Technical Standards Chapter 7.1 for roofs and balconies. Cold Polyurea also offers a long-term solution with a 25+ year life expectancy. The system is available with independent insurance backed guarantees of 20 years; an assurance that the system can withstand continued use over time.

Langley ensures that a fully bespoke specification is completed prior to the installation of the Cold Polyurea liquid roofing system, to ensure that the chosen system is carefully considered, specified and expertly installed, by one of a network of Langley Approved Contractors, for each individual project.

Market-leading single ply roofing manufacturer Sika Sarnafil, architects Cullinan Studio and Roofing Contractors Cambridge (RCC) are celebrating following a win at the first-ever AJ Specification Awards.

The roof refurbishment of the Central Building at Cambridge University’s Fitzwilliam College – one of the first major projects to use a pioneering, new approach to Sika Sarnafil’s products – came out on top in the Roofing and Drainage category.

Announced at a ceremony held at The Principal Hotel in Manchester on Friday 15 February, prizes were taken home across a total of 12 categories for projects demonstrating outstanding working relationships between architects, manufacturers and suppliers.

In what was a skilful collaboration between Sarnafil, Cullinan and RCC, the judges agreed there was something special about the way this unique brutalist building had been beautifully protected.

Comprising protruding ‘scalloped’ detailing, an innovative waterproofing solution was created to refurbish the highly complex roof, all without visually altering the original 1960s Denys Lasdun design.

Sika Sarnafil’s single ply membrane and Sikalastic 621 – a liquid-applied product typically used for areas with complex detailing – were used across large areas. This pairing of systems was further enhanced by Sika Refurbishment’s SikaFloor 420.

Sika Limited’s concrete products were also specified for the build by concrete repair contractors Gunite Eastern. Sika’s innovative concrete repair system included a steel corrosion inhibitor. Sika® FerroGard®-903+, which penetrates the concrete and forms a protective monomolecular layer on the surface of the reinforcing steel, was used alongside Sika MonoTop® repair mortars. The concrete was finished with Sikagard®-550W, a high-performance anti-carbonation coating, with crack-bridging capabilities, that protects the concrete, while meeting the aesthetic requirements of the structure.

Sika has a wide range of products available for most applications within the construction industry, which can range from waterproofing, flooring, concrete, sealing and bonding, facade, roofing and refurbishment applications, as well as teams of specialists available to advise on specific projects. Using a combination of systems, while working internally within the company, Sika was able to advise on the most suitable materials for different aspects of the project and ultimately provided a complete building envelope solution, with the client benefitting from having only one supplier to deal with.

Neil Smith, Technical Advisor at Sika Sarnafil, said: “We’re exceptionally proud that the teams across Cullianan Studio, RCC and Sika Sarnafil have been commended by the AJ Specification Awards. The winning project posed a huge design challenge, which was met with a unique approach and use of materials. Completed early and on budget, while the college remained operational throughout, the success of this project is testament to the close working relationships we foster with our highly skilled architects, contractors and clients, while also providing the best quality products.”

Dave Stewart at RCC said he was thrilled to see a project his team had worked on recognised in such prestigious awards: “The central Building Lantern roof was very unusual, presenting numerous detailing challenges that we welcomed. We worked closely with Sika Sarnafil and carried out multiple site tests to ensure the junction between the Sikalastic 621 and single ply membrane was formed using the most effective methods. The use of Sarnametal created a strong bond between the two products, enabling them to be successfully sealed together. This was a challenging and enjoyable project that demonstrates how well these products can work together for roofs with incredibly complex detailing.”

Alex Abbey from Cullinan Studio added: ”We are thrilled that, together as a team, we have won this award. This iconic, brutalist gem of a building is now renewed and preserved for many years to come due to an innovative shell, fascia and roof waterproofing solution, achieved through collaboration. The pioneering approach developed on this project can now be applied to protect other buildings, opening up new possibilities for roof design in the future.”

When a homeowner in Norwich was looking to transform his 1920s bungalow into a contemporary home that featured the most aesthetically pleasing building products on the market, he turned to Cembrit Westerland slates to provide a natural roof finish that complemented the new look of the property.

Previously a brick building with red Norfolk pantiles, the property looked run down, outdated and was badly insulated. Once the outside walls were insulated and rendered and new triple glazed aluminium windows were installed, Jon Barrell, the owner of the property, turned his attention to the roof.

“We became aware of Cembrit Westerland slates after researching what roofing materials are available” commented Jon Barrell. We wanted a light weight option that would look natural in its surroundings and would colour match the windows. The Cembrit Westerland slates ticked all these boxes. Not only that, but thanks to the thinness of the slate, we were able to raise the rafter line by 3″ to allow for an extra 2″ of insulation. We achieved this without having to alter the existing roofline or the need for planning permission.”

A total of 3,000 Westerland slates and 30 metres of Cembrit Slate Duopitch Ridge Ventilation were used to complete the re-roof, which was completed by Scott Sell Roofing. Jon didn’t want to introduce cement edges to the gables as a finishing detail, so opted for Cembrit PVC dry verges, which provided the perfect colour match to create a consistent finish across the roof. Following the project, Jon fed back to Cembrit that the roofing team enjoyed working with the Cembrit slates, as they found them easy to cut and fit.

“We had so many problems with the pantiles we used to have on our roof, and all of these issues have stopped now that we have had the Cembrit slates installed” adds Jon. “We no longer have moss growing and rolling down the gutters. Due to the surface of the ridges, the birds that used to sit on the ridges and leave mess no longer perch on the roof, meaning the roof always looks spotless! With the slates being installed in the correct tight-fitting manner, there is no draught between the slates or any vermin or other insects that used to be able to get in. We weighed the old pantiles against the Cembrit slates and have reduced the weight on the roof by 4 tons, which means no more creaking timbers or rattling tiles on a windy day. We feel that by opting for the Cembrit slates, we have achieved a classier looking project without the expense of a more costly product, which is not easy to do these days. We are over the moon with our new roof.”

Cembrit’s Westerland slate has a surface texture and dressed edge similar to that of natural slate but does not need grading and sorting prior to installation. Finished with a semi-matt acrylic coloured coating to the top face and edges and a tinted high-performance binder to the back face, the finish is of the highest quality. Easy to work with, as no power tools are needed to re-size the slates, Cembrit’s fibre cement slates simplify the install period and act as an economic alternative to natural roofing materials.

Westerland slates are manufactured in accordance with a quality assurance system to BS EN ISO 9001-2015 standard and to the requirements of BS EN 492: 2012 product specification for fibre cement slates and their fittings. Westerland slate has been awarded the BBA Certificate No. 03/4041. Cembrit’s fibre cement slates achieve the highest approvals from local national and international agencies in the fields of product quality and sustainability.

Cembrit Slate Duopitch continuously ventilated ridge tiles are specifically designed to provide a high level of ridgeline ventilation. Colour matched for use with Cembrit fibre cement slates, the ridge is suitable for pitched roofs ranging from 20° to 40°. The range includes start and end caps for a neat finish. Weighing 4kg, the product is lightweight, making it easy to transport and carry up to roof level. At 530mm in length, it is possible to carry two linear metres of ridge at a time.

Cembrit Slate Duopitch Ridge Ventilation is a fibre cement product that complements the smooth, flush look of the fibre cement slates. The ridges are lighter in weight than concrete alternatives, making them easier to install for a roofer working at height. The ridges do not require electric power for cutting, or any dust suppression equipment, equalling a much easier and quicker fitting process. They can be dry fixed with readily available colour matched Torx countersunk screws and installation is not dependent on getting the correct mortar mix, or having to wait for dry weather.

The construction of a massive new warehousing facility in Northampton has involved Hadley Group supplying unusually large quantities of its UltraMezzTM components to long-term customer Mezzanine International, with Hadley Group also supporting the successful erection programme throughout.

The two-tier mezzanine structure will provide Decathlon Distribution – a German based sports goods supplier – with some 17,000 square metres of space for storage and racking; and is the latest landmark project undertaken by the mezzanine flooring supplier and manufacturer during an eight-year relationship.

Kent-based Mezzanine International, which is active throughout the multi-channel retail, E-fulfilment, office development and other sectors, first tendered to Decathlon’s construction arm, ABK, for the contract in December 2016. Hadley Group responded to the scale of the work with a competitive price and reacted immediately when the work was awarded earlier this summer.

Beginning during the first week of August, Hadley Group has made weekly deliveries to the site on Thomas Dascher Way, keeping Mezzanine International’s team of two supervisors and up to 15 sub-contract operatives supplied with C-section joists, cleats and other custom formed components.

The Project Manager for Mezzanine International, Andy Parsons, commented: “This is a very large two-tier mezzanine, which has been designed and tendered for using Hadley Group’s dedicated DesignSuite Pro software package. The company also offered us an attractive volume discount to assist in our bid. Furthermore, the regularity of the design – on a 5.0 x 5.4 metre grid – means there is a minimal list of components required, but we are still taking a delivery of three lorry loads from Hadley Group’s Midland premises every week.”

DesignSuite Pro is an intuitive and customisable software package that supports the design and specification of projects based on Hadley Group’s cold rolled, high strength, lightweight UltraZed purlins and UltraBeam side rails and floor beams making project planning and specifying easier than ever before.

“The mezzanine rises 4.2 metres to the first level and 8.4 metres to the second. A big advantage of using the C-section joists is that our installers can hang them on the cleats as they bolt them up. Everything is rolled to order and pre-punched as necessary for fixings. Progress has been very good and we are expecting to complete two weeks ahead of schedule on a 10 week programme,” Andy Parsons continued.

While similar mezzanines would normally be completed with the application of an intumescent paint system and non-combustible boarding beneath the decking, the Decathlon Distribution vinyl- coated decking construction and its conveyor belts are to be protected with a full sprinkler system.

Going on to talk about other recent successes for the partnership, Andy Parsons added: “We have worked with Hadley Group on a number of high profile projects including a large warehouse for speciality drinks to store wine and other lines, and new distribution facilities for Amazon at Warrington, Bolton and Tilbury. All of these contracts involved very high loading requirements, for which we specified our Mezz-7 system. This involves Hadley Group supplying its B-Deck to support the main floor – making the installation seven times stronger than a standard mezzanine.

Hadley Group’s UltraMezzTM selection of components can facilitate the rapid and cost-effective erection of mezzanine floors for both new-build and retrofit applications. Offering enhanced performance based on the manufacturer’s unique UltraSTEELTM process, the UltraMezzTM design and project management process cuts waste and avoids errors, while further support is available from Hadley Group’s technical sales team.

Cembrit is pleased to announce that it has received approval from the British Board of Agrément (BBA) for its cladding product range, providing peace of mind to specifiers who choose to use Cembrit’s non-combustible fibre cement cladding boards on their projects.

What is certified?

Cembrit Patina, Solid and Cover are all “A2-s1, d0” fire rated fibre cement rainscreen cladding panels. They have been assessed by the BBA and awarded certificate number 18/5600 for use as exterior non-load bearing, decorative external cladding on timber or metal vertical supports over timber frame, steel frame or masonry external walls for both new and existing buildings.

Cembrit Ltd’s Managing Director Thomas Heldgaard observed, “This was a long time coming. The assessment procedure demonstrated improvements to our processes which have been incorporated in the finished product. We are pleased that such a rigorous assessment process has resulted in an accreditation that has real value to the specifier.”

Why the BBA?

The British Board of Agrément is one of the UK’s leading notified bodies offering approval, certification and test services to manufacturers of products and systems supplying the construction industry. BBA approval is recognised by building control, government departments, architects, local authorities, specifiers, and industry insurers like the National House Builders Council (NHBC). Independent confirmation that the products covered by a BBA certificate are fit for purpose is a significant advantage for specifiers. The certification ensures peace-of-mind that BBA 3rd party approved products match the required specification. and comply with Building Regulations and the recommendations of other approved bodies, such as the NHBC.

What is assessed?

The BBA Certificate 18/5600 was awarded after Cembrit Patina, Cembrit Solid and Cembrit Cover all passed a series of comprehensive assessments, including laboratory tests, on-site evaluations, quality management checks and inspections of production. The process was lengthy, intense, demanding and thorough, but the result is that specifiers can be confident in selecting a rainscreen cladding that is fit for purpose. At a time when cladding products and the specification process is under such scrutiny, knowing that a Cembrit rainscreen meets the performance, durability and occupant security demands makes the job of rainscreen selection less worrisome.

BBA inspectors visit factories and construction sites to evaluate the product development process and assess the functionality of the product/system on site. This ensures that the manufacturing and storage is consistent with building regulations and guidelines

Other considerations

Cembrit fibre cement decorative rainscreen claddings are marketed as the most cost competitive fibre cement claddings available in the UK.

Simon Mayes National Sales Manager commented, “We have a product that is equal to any fibre-cement cladding on the market and at a competitive price!”

Marley introduces new colour to popular Edgemere slate range

Following significant increase in demand for cost-effective alternatives to natural slate, Marley has further enhanced its slate offering by introducing a fourth colour to the popular Edgemere range.

The new Anthracite colour has been developed to provide a closer aesthetic match to natural slate and offers an affordable way to comply with planning requirements.

Daniel Redfern, product manager at Marley, explains: “There is growing demand for thin leading edge concrete interlocking slates, so this new finish for Edgemere provides greater choice within this popular range. Strict planning stipulations often determine product selection and we are confident the introduction of this attractive tile colour, which further mimics the appearance of natural slate, will result in an increased specification of Edgemere in areas where slate has historically been used.”

The new Anthracite colour option joins the existing range of Old English Dark Red, Smooth Brown and the most popular colour, Smooth Grey, which has seen strong growth due to the aesthetic trend towards slate-look roofs for new homes.

The slate-like appearance of Edgemere is further enhanced by its thin leading edge and the broken-bond laying technique. At only 18mm thick and sleek in appearance, the slates can be viewed as an affordable alternative to natural slate, or a cost effective upgrade from standard concrete interlocking tiles.

Daniel adds: “Edgemere has the ability to perform at pitches as low as 17.5°, which gives it the versatility to be used on a wide range of roof types. Increasingly people are prepared to pay a small cost uplift to get a premium roof finish and Edgemere offers a surprisingly affordable upgrade from standard interlocking tiles, with a high coverage rate of just 9.7 slates per square metre. Up to 40% thinner and lighter in weight, it provides a slate like appearance on a tile budget.”

The Edgemere range also delivers outstanding environmental benefits, with an A+ rating in the BRE’s ‘Green Guide to Specification’, BES 6001 Responsible Sourcing certification and, extra credits are available for the use of Edgemere on projects being built to the Home Quality Mark or BREEAM.

A wide range of fittings and accessories are available to complement the entire Edgemere range.
