It provides unparalleled knowledge and understanding of the designed world to the public.The newly refurbished entrance is the first porcelain tiled public courtyard in the UK. It consists of a total area of 1200 m2 distributed in different levels.For this application, FOAMGLAS® Tapered T4+ (Slab) was specified and installed on a concrete deck with two high performance bitumen waterproofing membranes.The bedding and porcelain tiles provide the final finish and they will support the large volumes of visitors expected every day.The podium roof at Exhibition Road Quarter will showcase the best of contemporary design, as well as celebrating the beauty of the V&A’s existing building.At the heart of the Architects brief the newly created space is to accommodate the V&A’s headline exhibitions, it will also act as a public area.The Foamglas strength and time tested thermal performance will offer a long term solution to this very important entrance and courtyard.

This building was once home to the Henderson Garage door production facility, with the client in the process of renovating the entire premises to be split into several new warehousing and office units. To be able to secure new tenants, however, there was an urgency to stop a mass amount of water ingress into the building, due to the roof's years of neglect.Systems in useHyranger®Starcoat® RChallengesThe state of the existing waterproofing was poor, meaning it needed to be stripped back to the metal deck below. Given the years of water ingress it was clear some areas of the substrate were deteriorating and would need replacing.There was also an issue with the adjacent metal cladding to the perimeter of the roof space, one of which was coated in an asbestos paint and the potential for asbestos rope within the old rooflights. All of this needed addressing prior to the roofing works commencing.SolutionsAxter were called to initially survey the roof area, highlighting the main areas of concern and interface issues. Following a roof condition survey report, proposals were put forward as to how best to detail waterproof these areas and achieve the brief set out by the client.To the metal cladding, Starcoat R cold applied liquid bitumen PU resin was used to create a waterproofed upstand without the need for the complete removal of the cladding. Upon discussions with the building owner, it was also discovered that the existing rooflights were no longer needed, so these were boarded over and waterproofed in line with the rest of the main field area.The Hyranger system, comprising polyester reinforced SBS polymer modified bitumen membranes, was ideal for the job due to its guarantee strength, stability, performance and cost efficiency.The completed roof gained a 20 year guarantee and extended the life of the building.

A lightweight solution... CHALLENGE A lightweight solution was required for the mounting of the PV installation on a production hall from Opel in Rüsselheim. For some years there existed no smart solutions for PV installations on roofs. Today we start to see the downside of PV roof installations that are not coping well with the weather conditions on top of roof constructions. Common mistakes made on PV roofs: • PV panels flying off the roof due to high winds where the attachments have not been strong enough and not fully tested. • Water leaks due to structural damage from the PV installation itself. Mainly due to the minute movement of the metallic/ aluminium PV-mounting on the roofing membrane. • Water leaks due to perforations through the roofing membrane when fixing the PV installation to the roof. • Roofs collapsing due to an excess of ballast of the ballasted PV installations. • Accelerated ageing of roofing membranes due to the use of incompatible materials on the roofing surface. SOLUTION RENOLIT ALKORSOLAR PV fixing system. This lightweight PV fixing system does not require extra ballast nor perforates the roofing membrane. The main parts of the system are PVC or EVA profiles that are heat welded onto the synthetic roofing membranes. This system is the only system that is fully tested for wind loads up to 200 km/h, has an Avis technique (France) and a DIBT approval (Germany).

The StoVentec Glass rainscreen system featured on the upper part of this 84,000 sq ft Marks & Spencer store in Maidstone was specified by architects Corstorphine & Wright for this £25 million project. 900m2 of StoVentec Glass panels were manufactured on a completely bespoke basis and finished in a pre-specified RAL colour to complement the modern design of the building and the other construction materials that were used. The StoVentec Glass system was designed and installed by specialist contractor Southern Maze Ltd, using Sto’s innovative sub-construction that can be mounted onto virtually all substrates, with no visible frames, rails or fixings. The store is regarded as a flagship out-of-town project for Marks & Spencer and features a bakery and food hall alongside other retail spaces. 

As part of a framework agreement between Gatwick Airport and Galliford Try, Bourne Parking were appointed to design and build an above ground scope of works for the over decking of Gatwick South terminal’s long stay parking Zones F and G. The single suspended deck car park provides an additional 1,224 car parking spaces and was built to assist with achieving Gatwick’s objective of passenger growth. The project is Shield’s largest and fastest single deck car asphalting project to date, with 26,000m² completed in nine weeks.

Systems in UseWilotekt®-PlusForce®Force Dalle®Aquamodul®OverviewBerkeley Homes initially contacted Axter in early 2017 about their project to create 844 apartments (including 175 affordable units), plus 8 shops, a restaurant, and a public plaza. The development, located in Edgware Road, will bring prosperity and jobs as well as housing, to a part of London in need of regeneration.The development involves 11 apartment blocks and is divided into 4 phases. Axter were involved in design prior to works starting, and were subsequently awarded the contract for Phase 1, later expanded to include Phase 2 and the current Phase 3.This is an update to a project we initially wrote about in its first phase. As noted there, Phase 1 was complicated by the fact that the Government amended the Building Regulations in 2018, after design work was completed and approved, imposing stricter requirements in relation to combustible materials in high-rise buildings. Timing meant that the developer was permitted to proceed under the old regime, but elected to apply stricter safety standards including a voluntary change to the system used on the balconies that was both tested to BRoof(t4) and included non-combustible insulation. The Axter team had to work quickly to amend designs but were able to modify the approved solution so that work could continue as scheduled.Phil Saunders, Regional Sales Director at Axter, has been our lead throughout the work. “This is one of the most challenging projects I have worked on,” he notes, “but also one of the most rewarding. Unique solutions were required to solve more than one problem, but it has been great to work on a development involving many technically elegant and aesthetically pleasing aspects, with a range of roofing systems and finishes, including Blue, Brown and Green Roof elements.”Additional challengesWestminster Council’s planning requirements included specific stormwater attenuation targets. With limited space onsite, Kevin Leahy, Technical Director at Berkeley Homes, was considering a Blue Roof solution, something the developer had not implemented before, so support from a technical manufacturer was especially important from the outset.Numerous other difficulties have had to be overcome during this project. Work was disrupted by Covid lockdowns not long after roofing commenced in 2019. Phases 2 and 3, which were very similar, also required us to support our partner through complex change: Phase 1 involved an inverted roof, a solution assumed to carry forward. However, assessment of weight restrictions and outlet positions meant that design would need to switch to a warm roof with tapered insulation.Additionally, work has continued throughout the period of the Ukraine conflict, where prices and supply of materials have been difficult to navigate.SolutionsTo achieve planning permission, Axter worked with Kevin and Berkeley Homes between 2017 and 2019, presenting the resultant roofing design for approval. We were able to demonstrate that the plans met sustainable drainage obligations. The London Plan for sustainable design and construction also imposed requirements, which were met by a mix of living roof solutions including Green Roof and Brown Roof finishes.“We’re happy to present Westminster Council to support the planning application,” continues Phil. “We have worked with Berkeley Homes many times and continue to do so on several projects. Nothing matters more to us than building and maintaining ongoing relationships with partners who know they can trust us to take weight from their shoulders.”Construction continued throughout the lockdown period, with Axter working hard to ensure uninterrupted supply. Materials continued to be delivered in a safe manner, and QA reviews were held virtually until we could resume our usual regular site visits.A switch in roofing approach generally changes the sequencing of work such as integration of roofing and door thresholds. “We were able to come up with an innovative solution involving multiple systems, including cold-applied liquid waterproofing, that permitted the original sequencing to remain,” says Phil. Change was also required in relation to upstand penetration details and movement joints.Throughout the project, Axter has been able to provide partners with full designs involving bespoke details, plus rainwater and u-value calculations, to ensure compliance at every stage.“We worked hard to find the smartest, most cost-effective solutions,” adds Phil. “We also appreciated that this was not the time to be too rigid in pricing. Some pain all round might be unavoidable in this difficult period, but we aimed to share the impact. We were also able to offer partners a guarantee of price stability for a set period of time, so they could proceed with certainty.”Axter manufactures its own systems and works carefully to plan ahead and liaise with long-standing supply partners. This allows us to stay ahead of shortages and offer accurate delivery timelines. Company-wide, we have been able to supply all systems as pledged.All of Axter’s approved installers must complete training specific to the systems involved, but in this case so many bespoke design elements were involved that we organised training specific to the project for all operatives. This training was also extended to the Berkeley Homes construction team, to ensure they were supported in how the roofing would integrate with other areas of construction.“This has been an exceptionally successful project”, comments Phil. “Hurdles have arisen, but with communication and hard work we have supported our client through rapid transitions and financial challenges. We have been very flexible on pricing, but we were not necessarily the cheapest initial bid. We were chosen anyway, because I think Berkeley Homes understands we add value that makes us the cost-effective option for the building’s future lifetime.”Phase 3 designs were approved early this year, with work just starting. Axter is now busy with design for Phase 4, with the project expected to continue through to 2025.

Metrotile Lightweight Roofing’s classic ‘Roman’ profile adorns the rooftops of a five building renovation ‘pilot’ project at Davis Road, DoncasterEach of the buildings is a prefabricated Hawksley Bungalow and has been modified throughout the yearsTo bring the homes up to ‘Decent Home’ standards, two major changes were made to the building’s exteriors. The first was a brick ‘skin wall’, that was built around the metal walls of the homes (adding a layer of insulation in the process). The other major alteration was that of a new roof in the form of a Metrotile lightweight tile system providing swift installation, traditional aesthetics and a low weight to reduce the load on the Hawksley Bungalow’s structure.

Our client wanted a low maintenance but high quality finish for the balconies on a build of high end flats and penthouses.Castlewood composite decking was chosen as it provides good slip resistance and a very luxurious finish. Our composite decking is very low maintenance due to the unique polymer cap that is applied to the decking boards during production. This particular deck board is supplied with a 25 year limited warranty for domestic applications and a 10 year limited warranty for commercial applications. Terms and conditions apply.Our aluminium substructure system was chosen as it is quick and easy to install and will never rot like traditional timber joists. The balconies also had very low thresholds in some areas that could not have been overcome with traditional timber joists.The aluminium substructure was assembled in frames with joists running at 400mm apart to provide adequate support for the composite boards. Additional joists were also installed to support the ends of each decking board where two ends meet.Each aluminium frame was then laid on our DD adjustable pedestals to make them completely level. Decking boards were then secured to the aluminium with our unique fasteners that work with our boards and aluminium profiles.If you have a project that may require this system please get in touch with your dimensions and we will happily provide a quotation for everything required.

EasyClick installation onto the Dunalastair Hotel’s large guest courtyard. Refurbishment of an old hotel in Perthshire recently carried out by London Developer Henley Homes who wanted to make better use of the ample outside courtyard spaces around the building, for functions and alfresco dining. Wallbarn pedestals were used in this project; they were secured to the concrete slab, beneath the deck, in order to give the deck strength and also to provide sufficient drainage capabilities, in the most extreme of weather. iDecking was then laid onto the pedestals using our exclusive “EasyClick”, decking solution.

We all know warm roofs and joist zones are huge areas for air leakage and extremely hard to solve this problem. This warm roof structure for luxury apartments retrofit fit onto an already existing block of apartments in Tottenham was typically the icing on the cake for detail and performance. With the hand cut roof providing the client with multiple skylights, dormers and 360-degree turrets, this was going to be no easy task of getting the airtightness and vapour control secure and correct in a traditional method. Step forward Passive Purple! Rather than just covering the issues, once the hand cut roof was finished, the 220mm roof rafters were filled with a layer of spray insulation supplied by Lapolla UK. The dormers, skylights and turrets were then given some attention to detail with Passive Purple BRUSH before the final application of Passive Purple (spray applied) This gives this roof a complete airtight vapour control with performance like no other and getting around all of them circular details and angle’s galore this was just another simpler, easier way to get the job done right and guaranteed! Passive Purple liquid application saves the client and user so much time and so much less strenuous labour.

The Egyptian Gallery was the first of many projects at the Museum to benefit from a replacement duo-pitch rooflight using Lonsdale’s ThermGard Roof Light System.After having procured roof lanterns of varying quality and with disappointing results from different manufacturers, the Client was determined to establish a design that met their very high criteria for thermal performance and protection of the priceless exhibits from damaging UV light. Whilst wanting the benefits of modern aluminium systems, there was a requirement for a ‘heritage’ appearance so that any replacement roof lanterns mirrored the original timber construction. High performance solar control glass was also specified to reduce harmful UV light to the exhibits below. Solar protection was further enhanced by the fitting of external shading blinds to the overhead glazing which produce the slightly ‘eerie’ affect that can be seen in this image. Such was the success of this initial project, the Client has held Lonsdale as the benchmark by which other roof light manufacturers are measured and we repay this loyalty by ensuring a first class job every time.

The roofs of The Dungannon & South Tyrone Borough Council offices had fallen into a poor condition and a large amount of standing water was threatening to leak into the offices below. With the office roof areas in such a poor state, the council turned to Polyroof to refurbish nearly 1,000 square metres of roof, split into 13 areas, before they fell into a further state of disrepair. DTL Construction, a local Polyroof Approved Contractor, were tasked with installing the Protec System, removing the issue of standing water and giving the roof a long service life, whilst giving the council peace of mind that leaks would not pose an issue in future.The standing water was cleared before the existing roof materials were stripped back in order to install the new system. This allowed a new warm-roof system to be installed, along with new cut-to-falls insulation. Polyroof’s Protec Cut-to-Falls insulation is an innovative two-layer system which doesn’t only improve thermal performance, it also directs standing water away from the roof.Following this, the BBA-approved Protec system was used to seamlessly waterproof the entirety of the office roofs. The system, once inspected by Polyropof’s Technical Services team, was issued with a 20-year guarantee, so the client could now have reassurance their roof would last for decades to come.

The building that would be the St Margaret’s Primary School, officially opened by Robert Leitch the local parish vicar in 1889 provided education to children up to fourteen. The school underwent many changes in structure throughout its over 100-year existence continuing to provide the high level of teaching it always held. In 2012 it underwent a further change in the form of a huge modernisation project that would extend the school and allow more students to be taken. Unfortunately, leaks were reported on the older parts of the building and despite localised repairs were not ultimately solving the problem.After reports of leaks it was imperative that the roofs in question were inspected to find where the issues were originating, in action to this a site survey was undertaken. The survey highlighted the original build-up consisted of an asphalt on a timber deck, this original system was in a aged condition. It was also shown that standing water and vegetarian had developed on the roof. In order to protect the building from further leaking it was determined that the roof would benefit greatly from the installation of a high-performance waterproofing system.Along with waterproofing improvements, there would also be improvements made to the falls which would reduce the amount of standing water present on the roof.Waterproofing would not be the only recommendation; the roof was also to receive a full thermal upgrade which would further provide the benefit of increase fuel bills and less energy consumption for the school.Taking into consideration all these points, the Polyroof Technical team began creating a bespoke specification that would provide the details needed to make these recommendations a reality. The Polyroof Approved contractor Thomas Cassie & Sons was specifically chosen to undertake this project due to their experience in liquid roofing systems. With a specification and approved contractor ready the project could officially commence.

Composite Decking - Interlocking Dura Deck Tiles | Case StudyThe RHS Chelsea Flower Show is a renowned annual garden exhibition held for five days each year by the Royal Horticultural Society (RHS) in the grounds of the Royal Hospital Chelsea in Chelsea, London.Gorilla Carts and Kiosks were chosen to supply anti-slip modular flooring to enable safe access around the food courts. Using the innovative fast-fit interlocking Dura Deck Tile product designed and manufactured by Dura Composites, Gorilla Carts and Kiosks were able to quickly and easily install hundreds of square metres of outdoor flooring which provided clear demarcation of pedestrian standing and seating areas. Anti-slip, durable, and with an attractive woodgrain composite timber finish, the tiles interlock quickly and easily for set up and removal – and can be laid on virtually any existing hardstanding to create a simple decked area.

Working with Williams Roofing Contractors Ltd of Eastleigh, Hampshire, the winning project involved the refurbishment of a large water treatment plant that imposed stringent environmental and performance requirements.The outstanding workmanship and attention to detail by the Polyroof approved contractor during this large scale installation allowed this project to really stand out from the crowd. The below is a case study for this LRWA award-winning project, highlighting the many challenges and how they were overcome through innovation, workmanship and product choice.The SolutionFollowing a survey of the roof area conducted by Williams Roofing and Polyroof Technical Services, a detailed report was carried out after which a bespoke specification was produced and handed to the client. This document detailed a comprehensive set of recommendations for solving the issues that had arisen due to the aged condition of the roof coverings.The client, satisfied that the solution proposed would provide the lasting peace of mind they were looking for, awarded the contract to Williams Roofing Contractors Ltd to install the Polyroof Protec System.There were many challenges on this project as this was a live ‘Clean Water’ environment site, so all Williams Roofing Contractor staff on the project had to have the EUSR National Water Hygiene Cards and be fully inducted by Southern Water’s high standards. Working within these type of environments brings additional Health & Safety implications as the National Water Hygiene scheme is in place to ensure the protection of public health and promote safe drinking water practices. Further risks had to be considered and covered including the risk of working over open water areas with additional buoyancy aids on site to reduce the risks as described under CDM regulations.Williams Roofing Contractors Ltd had to be especially vigilant providing additional protection to ensure that no potential contamination or spills caused any contaminants to the clean water processes/water courses and environment with additional spill kits on hand. Due to the varying conditions of the roof construction(s)/substrates the preparation had to be thought through thoroughly. Certain roof areas needed to be scarified which would have caused reverberations through the roof/concrete deck. This would have possibly created contaminants by spooling of concrete/debris/dust to within the MF Compound Water Lanes/Tanks.

AliDeck has recently partnered with ISWUK and 8build to undertake a significant terrace decking project at 3 Sheldon Square, Paddington, London. This collaboration will showcase the innovative application of the AliDeck Senior board and Balcony Drainage System across multiple floors of the terrace deck, which overlooks a high-profile urban setting.

The refurbishment was created with a light touch but transformed the main building entrance and reception, upper-floor common areas, WCs and half of the office floors. Work was undertaken whilst the other office floors remained in occupation.The reception refurbishment reused many of the existing high-quality materials, which complements terrazzo, but also helped to transform the space into a contemporary interior whilst retaining the grandeur and sense of arrival.Terrazzo is also in harmony with the edgier interventions such as the distressed metal ceiling raft and lighting which have contributed to the building appealing to the next generation of banking tenants with start-up bank Monzo taking the vast majority of vacant space in the building.The gentle approach to refurbishment and the reuse of materials as well as the use of terrazzo contributed to meeting British Land’s exacting sustainability targets.

Ghent Diamond CHALLENGE The Ghent Diamond is proudly overlooking the Ghent-Sint-Pieters railway station and surrounding neighbourhood. On top of a stonelike base with a pattern inspired by the city of Ghent’s historical architecture, an impressive crystalline edifice rises. The 33m high office building has – as the name indicates – not only the brilliance, but also the shape of a gigantic, polished diamond with numerous facets. The special design makes the building unique, and that is exactly where the difficulty lies: roof surfaces with different inclines, steep and hard-to-reach slopes, kinks in the façade and a serious wind load. On the pitched roof segments connecting the glass facade, an exterior roof finish with Linius RENSON blades is to be installed. Just for aesthetic reasons! Such a finish creates a nice play of light, shadow and reflection. But this can only be achieved if the finish has been executed perfectly! But how to execute the construction so precisely, and at the same time be perfectly watertight? A true challenge for both architect and roofing contractor. SOLUTIONFor the internationally renowned New York-based architects practice Asymptote this monumental Diamond project is just another jewel in the crown. Innovative and visionary, they always pursue extreme and experimental challenges. And yes, this impressive Diamond really was a challenge, especially for the Belgian ROTEAM roof experts. The special shape, the height and the different slopes up to 47° made it a complex, gargantuan waterproofing project. On top of the steel deck structure tongue and groove insulation panels were installed. This guarantees a strong, perfectly fitting and smooth construction. After all this is very important in order to achieve this monumental task. The high wind load and shear forces were decisive for the choice of roofing membrane to be used on this difficult structure. Asymptote architects therefore opted for the mechanically fastened RENOLIT ALKORPLAN F membrane. This PVC-P roofing membrane is specifically suited for such a project, thanks mainly to its flexibility, lightweight and long life.

Some of our most important public sector assets are held within the healthcare system so choosing the correct specification is critical. Often these buildings host patients or the latest medical equipment, and this centrally funded NHS project at Chase Farm Hospital was no different. This particular project hosted an array of plant and equipment for the NHS and our lightweight DANOPOL HS 1.5mm mechanically fastened membrane was chosen as the waterproofing system to be installed onto the structural metal deck. The scheme also featured a tapered insulation scheme in partnership with Kingspan Insulation designed to 1:60 falls and 0.30 w/m2 K u-value. When installed to structural metal decks, all the mechanically fastened components are mechanically fastened to the crowns only, so careful consideration must be made to ensure that any mechanical fasteners coincide appropriately. A project-specific wind uplift calculation was completed by our technical team which provided detailed instructions and fastening patterns for the mechanical attachment of both the waterproofing membrane and tapered insulation scheme. In addition to ensuring that the system will resist any applicable windload, our calculations can reduce overall frequency of fasteners, ensuring that the project is not over-engineered and ensure that the installation progresses as quickly as possible.Waterproofing Systems:DANOPOL HS 1.5mm - Light GreyConstruction Type:New BuildWarm RoofSector: Public Sector Approx.

HMS Caroline – Museum ship... CHALLENGE HMS Caroline, the last surviving vessel from the 1916 Battle of Jutland, now rests in the Titanic Quarter in Belfast. After a second life as floating Headquarters of the Royal Navy during World War II, this living legend will continue to serve the country as a museum ship. For this purpose, however, extensive restoration appeared to be essential. The key requirement on HMS Caroline was to avoid penetration of the deck surface. To safeguard its historic heritage against damage, the Royal Navy sought a reliable waterproofing solution. SOLUTION Versatile and impenetrable! What used to be the properties of this battle cruiser, happen to apply to the RENOLIT synthetic single ply roofing membranes as well. That’s why RENOLIT ALKORPLAN was heralded as the optimal solution for the refurbishment of the ship’s gun deck. The lead grey RENOLIT ALKORPLAN A provided an ideal modern day solution with an impressive finish. On top of a new layer of insulation board, the calendered and laminated fleece-backed PVC membrane was fully bonded with a combination of the RENOLIT ALKORPLUS81068 polyurethane adhesive and the universal RENOLIT DUALFIX81065 glue. RENOLIT ALKORPLAN stands out above the competition given its excellent weldability, simplicity of detailing and overall versatility. Once installed, ongoing maintenance of the membrane will be minimal with a predicted life expectancy in excess of 35 years (BBA approved). On 31st of May 2016 the freshly refurbished HMS Caroline stole the show as a fitting backdrop for a commemoration honouring its centenary. 

Buzon UK were commissioned alongside The Outdoor Deck Company to refurbish the external terraces of several top floor apartments located on Nile Street, moments from Old Street, London.

Buzon UK supplied and installed PB pedestals, which were placed under each rail to support the GRAD ThermoAsh deck boards. The GRAD system can either be fitted onto conventional timber joists, or mounted onto the bespoke support rail system.

“Bosco Verticale” by Stefan Boeri.The vertical forest - that's what the 119 and 87 meter high apartment towers in Milan's new city are called and have been an example of ecological building since their completion. The reason: The two buildings are surrounded by overhanging balconies that provide a home for 730 trees and 20,000 other plants. A “stacked park landscape” above the roofs of the city, green and emitting CO2 . Built with RETANOL® screed.

Roofing slates by Welsh Slate star in presenter’s new TV programme.Roofing slates by Welsh Slate were the material of choice for TV property expert Sarah Beeny’s own home-in-the-making which is the star of the Channel 4 series “Sarah Beeny’s new life in the country”.The “Homes on 4” series follows Sarah and her family (husband and four sons aged 11 to 17 years) as they swap London life for a new start on a 220-acre, semi-derelict former dairy farm in Somerset, where they are building a modern and sustainable stately home of their dreams.

Secreted within the grounds of a Victorian villa these 2 new Mews properties and 3 new Townhouses replaces demolished 1980’s office facilities. A strong masonry base envelopes a timber clearstory and gables, aluminium dormers and a Zintek Mediterranean Blue zinc roof, to give a truly contemporary interpretation of a traditional mews building. The Townhouses are formed with complex twisted geometries. As with the adjacent mews, materials were selected incorporating a solid masonry base, timber cladding to the projecting cantilevered boxes, aluminium glazing systems, white render and topped with blue zinc mono-pitched roofs.

Whitburn Partnership Centre was designed by Project Architects, Matthew Fair, Neil Forrester and Jamie Bateman at Smith Scott Mullan Associates for West Lothian Council. The design of the contemporary £4M building restores the historic Whitburn Burgh Hall original façade as it is one of the towns most renowned buildings and incorporates a new-build two-storey extension.Located in the centre of Whitburn, this building is a community hub that embraces the West Lothian Council’s model of bringing together services that benefit local communities whilst delivering financial efficiencies through the decrease of council buildings. This building facilitates a library, community halls, museum and customer information service office, making it an important community resource. Project:Whitburn Partnership CentreProject type:New buildLocation:West Lothian, Scotland,Waterproofing:Bauder Total Roof System (BTRS)Roof size: 525m2Energy generated from PV array: 10.35kWp Specifier: Smith Scott Mullan AssociatesMain Contractor: Maxi ConstructionApproved contractor: ProCladd (Scotland) LimitedSolar PV installer: Intelligent Electrical SolutionsThe specificationTo support the West Lothian Council's sustainability objectives of achieving high energy efficiency, it was our responsibility to specify a waterproofing system and provide a solution for natural energy generation. The bituminous Bauder Total Roof System (BTRS) was chosen for this project as it features membranes that can withstand impact and tearing, as well as thermal insulation that met the required U-value of 0.15 W/m²K. This waterproofing system is verified by the BBA and offers a service life in excess of 35 years.The BauderSOLAR system was also specified, as it incorporates photovoltaic arrays for natural energy generation. The photovoltaic mounting system is attached to the roof without penetration of waterproofing or the deck, safeguarding the integrity of the waterproofing to fulfil its full-service life.Project challengesThe Architect’s design incorporated unusually high parapet upstands, which posed a challenge for installers. Area technical manager for Bauder, Christopher Langton, attended design meetings with the Architects and Main Contractor to discuss the best solution for installation. A mutual agreement was made for the underlayer to be mechanically fixed to prevent any slippage of the capping sheet membrane. Due to the height of the upstand, non-combustible insulation BauderROCK was incorporated into the design at these details.The installation of BauderSOLAR F uses prefabricated bituminous BauderK5K membrane sleeves to slip over the mounting plates and welded into position, anchoring the plates to the surface of the Bauder waterproofing system. Approved BauderSOLAR installers, Intelligent Electrical Solutions, installed the BauderSOLAR system, collaborating with ProCladd, approved contractor for the waterproofing installation, and other trades during the roof installation.There is a junction where the flat roof meets the original slate roof of the adjacent building, this detail fell under the torch free zone that hot air welding techniques are used to install the membranes within these areas.The resultInstallation of the Bauder waterproofing system may only be carried out by trained and certified operatives approved by Bauder. A project pre-start meeting was held by Bauder site technician, Duncan Hastings, and area technical manager, Christopher Langton inviting the Site Manager from Procladd and their Bauder badged operatives. During this meeting, they discussed the installation of the project, and identified the areas that required torch-free and torch-safe detailing. They also discussed how the project was going to be delivered in co-ordination with other trades working on the site at the same time, for example cladding and lead that was installed atop the waterproofing upstand details.Weekly site-inspections were carried out by Bauder site technician, Duncan Hastings during the project. Visiting the site frequently meant that Duncan could provide consistent support to the installers and answer any questions they may have had directly. It also meant that the quality of the roof installation was being monitored regularly to ensure it would be to a high standard, achieving the comprehensive guarantee.The approach taken to deliver this project on time and to budget was through meticulous planning and working to tight time frames. The organisation of the delivery of Bauder products to site had to be in line with the schedule to ensure that the site was ready to receive a delivery. With the project located in the busy centre of Whitburn next to a cross junction with traffic lights. This meant that timed delivery of products to site was required in addition to prebooked off-loading by pump truck and tail lift or by telehandler.Health, safety and environment was managed during the planning, design and installation of this project by advising that all installers follow the advice shown in the “Responsible Specification Checklist” produced by the National Federation of Roofing Contractors.In accordance with the Workplace (Health, Safety and Welfare) Regulations 1992, roof edge protection in the form of scaffolding was installed during installation. The project’s perimeters were surrounded by Heras fencing to isolate the construction site from the public. All scaffolds that were on the elevation next to the public had toe boarding and safety mesh where required.As standard, there was a one-hour Firewatch after the Bauder membranes have been installed using a gas torch. This was carried out by Procladd operatives each day when they were working on the project to ensure the welfare of the workforce, and the safety of other trades and that of the building. The 19kg gas cylinders were used on this project as they are easily transportable on the roof area.

Latvijas Finieris is increasing its production volumes of lignin-based green glue Riga ECOlogical, and the new product is gaining popularity among architects and interior designers. The design bureau br.ook interior architecture, in one of their latest projects – library of Andrejs Upīts Secondary School Skrīveri, Latvia – chose to use Riga Ply and Riga ECOlogical for their interior solutions. Interior architect Baiba Rūķe, br.ook interior architecture, comments: “The initial idea was to create a multifunctional space, yet we wanted the environment to be clean and natural for creative activities. The birch plywood is good material due to its durability and vast application options. It is also our local product. As interior architects, we pay a great deal of attention to materials that we use in our projects and we look for solutions that focus on air quality. It was interesting to use this material, which is natural and has a focus on sustainability.”The library is special, not only because of the high-quality materials used in the renovation process, but also due to its functionality. The idea of the project was to transform the library into a meeting place where one can get familiar with the latest books, do homework in a pleasant and quiet environment, as well as organise other educational activities for children and the youth.

The village comprises of holiday accommodation and facilities for sports and leisure, including a gym and restaurant. Many of these facilities are based inside the Unison Clubhouse, which was roofed in corrugated tin – an old material ill-suited to a focal building and in desperate need of a refresh.Metrotile Slate .900 was chosen as the replacement for its clean aesthetics and its high impact and weather resistance

The M4 Junction 3-12 motorway upgrade project, which started construction in July 2018, is designed to increase capacity, and reduce congestion between Junction 3 (Hayes) and Junction 12 (Theale). In the sections where there is no pre-existing hard shoulder for conversion into an additional running lane, a total of 11 overbridges needed to be demolished and replaced with longer decks to enable continuity of the widened carriageway. The £848m project is due for completion in Spring 2022, by which time it is expected that approximately 680,000t of material will have been excavated, 1.8M.m² of new surface laid, 130km of cabling installed and 63km of concrete barrier positioned. Cordek were approached by the Principal Contractor Balfour Beatty VINCI joint venture to provide a lightweight structural fill solution to be used for the embankment construction adjoining the Datchet Road Overbridge, between Junction 5 and Junction 6.

The new £65 million, Science, Engineering and Environmental Building (SEE Building) at the University of Salford was designed under the concept of incorporating high sustainability credentials. This supports the university’s pledge in reducing the environmental impact, as part of the wider Salford Crescent and University District masterplan. The SEE building promotes innovation, environmental protection and excellent educational opportunities and offers students state-of-the-art facilities with the aid of the LAMILUX Glass Roof PR60. A stunning skylight measuring an incredible 44 metres long and 9 metres wide, as well as three other Glass Roofs PR60, were installed onto the roof of the four-storey building, illuminating the lecture halls and common areas. This results in enhancing the natural daylight, whilst also allowing for natural ventilation, creating an inspiring environment for learning and development. To avoid overheating and glare inside the building, special 60/30 high performing solar glazing was used. This innovative technology ensures a comfortable indoor climate whilst providing an optimal learning environment.LAMILUX worked with the architect from the early planning stage of the project to design, supply, and install the four rooflights. “Just-on-time” deliveries were planned to enable offloading of the materials, with a crane, from the vehicle to the roof, to minimise loading out as space on site was very limited. Integrated ventilation panels were installed within the three smaller PR60 Glass Rooflights to provide the ideal solution to provide natural ventilation into the building alongside natural daylight.The largest rooflight was glazed with an impressive total of 120 fixed glass panels to make up the impressive 44 metre length and complete the installation. The glass panels were specified with Class 1 Fragility, suitable for walking on for cleaning and maintenance loads, according to CWCT TN 66 /TN 67 & TN92. Before the final handover of the project, extensive water tightness testing was carried out. On site CWCT hose tests were passed successfully, as testament to the quality and durability of the installation led by the LAMILUX installation team. The University of Salford is passionate about sustainability. LAMILUX are proud to be involved with a building project that not only contributes to the progressiveness and commitment to sustainable architecture, but is also considered a BREEAM Excellent-rated facility.

The NHS Estates Team required a new office space and workshop area and proposed the refurbishment of an existing building.Systems in useHyranger®Starcoat® PMMAOverviewAxter Ltd were instructed by William Gough & Sons Ltd to produce a design for six roof areas, following a site survey report. The project included a mixture of new build and refurbishment areas, comprising of various systems and design requirements. This included a cut to falls insulation design to comply with Part H and BS 6229:2018. Roof A, the focus of this case study, had a series of convex or ‘barrel roofs’, requiring bespoke detailing and careful design to achieve robust detailing and the required U-value.The project value was circa £1 million. This included all building works and a strict budget for the roofing package, which was achieved. The programme for the works was 16 weeks and completed in Autumn of 2022, to the required deadline.The successful project was also nominated for a National Federation of Roofing Contractors (NFRC) award 2023.ChallengesAxter were appointed at RIBA Stage 2 to undertake site surveys and work alongside the Principal Designer as Designer under the Construction Design and Management Regulations 2015.The existing asphalt had shown signs of cracking and blistering, and the outlets were damaged from vegetation growth from a lack of maintenance. New outlets were installed with leaf guards, allowing free flowing water whilst preventing blockages.The proposed office section of the works required thermally upgrading to comply with Building Regulations: Part L. The U-Value requirement was 0.18W/m2K which could be achieved with a 120mm PIR flat board. Due to the curved profile of the roof, installing the insulation below deck level was considered. However, due to an inadequate ceiling height this was disregarded.Furthermore, this would have resulted in the development of interstitial condensation. Further design solutions had to be considered. To bend a 120mm board would have required multiple cuts to the insulation so the decision was made to split this into two thinner boards to achieve the radius more easily.When split into two layers the requirement changed to 2 x70mm boards (140mm total) as worked out using U-Value calculations by the in-house design team at Axter. A timber hard edge was introduced to abut the insulation at the building perimeter to separate the façade and the main field area.Systems and productsAxter’s Hyranger multi-layer RBM system was used across all six roof areas. The system is fully BBA and BRoofT4 compliant, and achieves a guarantee period of 20 years. For this project, Axter’s Goldshield Guarantee was chosen, which covers materials, workmanship and design liability. This was overseen on site by Axter’s Quality Assurance team, who audited the project inclusive of the installation, safety and general management of the roofing works.Axter Starcoat PMMA was used as a cost effective solution to coat the copper fascia and provide a fresh and seamless look to the exterior of the building.SolutionsThe Axter Hyranger multi-layer RBM system was installed using traditional gas driven torches to fully bond the (AVCL) Air and Vapour Control Layer and cap sheet layers. The underlayer was installed over a tissue faced PIR and therefore needed to be self-adhesive in order to reduce the risk of fire, complying with NFRC Safe2Torch guidelines. A cold applied Starcoat PMMA liquid was installed to the façade to achieve a seamless and cost-effective upgrade.The Axter Quality Assurance Team regularly attended site and were in constant communication with the appointed Axtershield Installer, Empire Roofing operatives, to ensure that the system was being installed correctly and to the expected standards in order to achieve the Goldshield guarantee required by the client. To achieve the guarantee level, all materials and workmanship had to be installed as per the Axter specification.The site agent from the main contractor was also regularly on site to oversee the project and ensure that deadlines and timescales were being achieved to keep the build on target for completion. The installation of the multiple roof areas was achieved to exceptional standards leaving the client very impressed with the workmanship.AcknowledgmentsWilliam Gough & Sons Ltd were very impressed with Axter Ltd on our first scheme with them at George Eliot Hospital in Nuneaton. The requirements of the scheme, which included a complex barrelled roof were investigated on site early in the design phase of the project and Axter’s recommendations were swiftly proposed and agreed with the client’s Architect. Once the design requirements had been established one of Axter’s approved installers were employed by us to very successfully deliver the scheme. The 20 year Goldshield guarantee provided for the Reinforced Bituminous Membrane system offered peace and mind to our client. Chris Hinton, Senior QS, William Gough & Sons
