"roof decking other materials"

Cranbrook Primary SchoolBauder Total Roof System (BTRS) with Tapered insulation schemeSynopsisCranbrook Primary School in Ilford, London, was experiencing some major water ingress due to the advanced deterioration of the existing roof system. A roof survey was conducted by Stuart Parratt, Bauder area technical manager, where core test samples were taken to identify the existing roof construction to deck level and to provide an indication of the roof condition. The survey revealed that the existing waterproofing was in extremely poor condition, with extensive evidence of water ingress.  Bauder Building BoardProject:Cranbrook Primary School Location:LondonProject Type:RefurbishmentRoof Area:440m² Client:London Borough of Redbridge Council Approved Contractor:Thameside Roofing Ltd The specificationThe original waterproofing had been poorly overlaid with EPDM which had subsequently debonded. Before the installers could begin laying the new system, they had to strip the substrate back to the original asphalt. The client required a robust system that would deliver durability, value and longevity. 390m² of bitumen waterproofing, Bauder Total Roof System (BTRS), was specified for the main roof areas and 50m² of our cold applied liquid waterproofing, LiquiTEC, for an area that had limited upstands due to clerestory windows that could not be repositioned. Products appliedBauderPIR tapered insulation  A lightweight and cost effective alternative method of providing falls to a roof, whilst also providing thermal insulation. The client opted for this scheme at Cranbrook to minimise standing water on the roof. Bauder Total Roof SystemA two-layer bituminous waterproofing system robust enough to withstand foot traffic and most permanently sited plant. For use within warm and cold roof scenarios, as well as overlaying existing roofing materials. BTRS meets current UK Building Regulations Part B for external fire protection and features torch-free and safe to torch installation on combustible details. LiquiTEC Cold Applied liquid waterproofing Utilising Bauder’s PMMA cold applied liquid waterproofing on one of the roof areas ensured a fully watertight solution around rooflights and below upstands that could not be raised.  Project challengesAlthough the deck appeared to be in a reasonable condition for reuse as part of the refurbishment, there were large deflections to some areas and the existing waterproofing that overlaid the original system had been poorly installed and had pulled away from the asphalt below and so needed stripping prior to works commencing. The existing insulation was inadequate and left the building falling short of the current requirements. A thermal upgrade was incorporated into the works using a tapered insulation scheme which helped to solve the deflection issues by creating falls on the roof. To meet the minimum upstand requirements, the existing extractor vents needed to be removed to allow for the increase in the kerb height. Large continuous structural rooflights providing natural light to the building below were deemed thermally inefficient. The rooflights were upgraded during the refurbishment to meet current standards.  The resultBauder systems are only installed by Bauder approved contractors to ensure quality. The installation on this project was expertly carried out by Thameside Roofing Ltd, overseen by Dave Gregory and John White. After sign-off from Bauder site technician, Paul Osbourne, this system was awarded a comprehensive guarantee.  Systems installedBauder Total Roof System (BTRS) with Tapered insulation1 Bauder K5KHeavy duty, torch-applied SBS elastomeric bitumen capping sheet featuring a spunbond polyester reinforcement to allow the finished product to cope with structural movement without fracture, and a mineral finish to provide protection against UV degradation.2 BauderTEC KSA DUO Technically advanced self-adhesive SBS elastomeric bitumen underlayer with “DUO” lap technology to ensure thorough sealing of lap joints, even in lower temperatures. 3 BauderPIR FA G16Tapered PIR Insulation board manufactured in accordance with BS EN 13165 with no facings.

Modern materials were employed in the quest to recreate part of Bristol’s heritage. SIG Design & Technology supplied IKO’s Armourplan PSG single ply membrane because it fitted the bill perfectly as the roof covering was ideal for replicating the original seamed lead roof.

Canadian Western Red Cedar Timber Cladding has been used as the primary external material on this private home in The South West, local to Bristol.A well thought out design is key when working with Timber Cladding as a façade material, on this project you can see the consideration has been made to ensure there are no large soffits that would hinder the weathering to silver/ grey as UV light hits the timber. Likewise a consideration has been made for the lengths available of the material, opting for prescribed breaks in material on a number of elevations, rather than opting for random or staggered joints.Tongue and Groove boards were selected for the main property in a horizontal installation, with a board on board design chosen for the verticals that can be seen on the outbuilding. On both structures visible stainless steel fixings have been used, although Canadian WRC is a timber than is stable enough to be secret fixed, the fixings work well on this property with the other design characteristics.Longer term; no coatings were applied to the cladding, allowing it to naturally weather down as can be seen in the photos. In turn there is almost zero maintenance to carry out, other than the usual of keeping the material clean from any dirt or debris that can build up over time from pollutants in the air.

Battersea Reach, an award-winning development consists of 1,350 apartments spread over 14 separate buildings surrounded by beautiful landscaped gardens, shops and cafes. Buzon UK supplied and installed the DPH pedestal range for the composite decking and paving to many of the terraces and balconies across the 14 separate apartment buildings. The DPH pedestal system is perfect for use at roof level as they allow for 5% slope correction and can accommodate a range of services beneath floor level as well as giving excellent drainage.

One Hyde Park is a major residential and retail complex located in Knightsbridge, London. The development includes three retail units totaling 35,800 m2 and 86 residential properties with prices starting at around £20 million. Buzon UK installed 28,000 DPH pedestals to support Ipe timber decking to all roofs across all four buildings. The project was a success and Buzon UK were proud to be involved in installing their first-class products to one of London’s most prestigious developments.

WMOR Architects completely redesigned the ground floor to include a flexible living area to open into the garden. Accoya was chosen as the ideal material for the extension because of it aesthetic appearance as well as its ability to provide better insulation than other materials. & the owners wanted to use the most sustainable material they could. The Accoya extension which houses the show piece kitchen will be left to weather naturally and match the pale grey flooring. This was specifically designed so that in the summer, when the sliding door completely opens, the interior & exterior space will merge seamlessly.

Cambridge University, Department of Civil EngineeringBauderBLUE STORMcell with BauderSOLAR G LightSynopsisThis new build project in the centre of Cambridge combines a Sustainable urban Drainage Solution (SuDS) with vegetation and renewable energy in a warm roof construction.The client for the Department of Civil Engineering at Cambridge University, R H Partnership, identified sustainability as being a key driver in the design of the roof, but also sought a single source supplier that could provide a guarantee for both workmanship and products. Bauder’s systems range encompasses products to meet all the sustainability objectives, and with our network of approved contractors carrying out the installation, we could offer the comprehensive guarantee that was required.Bauder Building BoardProject:Cambridge University Department of Engineering​Location:CambridgeRoof Area:1610m²Client:University of CambridgeSpecifier:RH Partnership ArchitectsMain Contractor:SDC LimitedApproved Contractor:Voland LimitedThe specificationTo meet the sustainability criteria set out by the client, the Bauder technical team designed a roof system combining an extensive blue roof, a green roof and a solar PV array. The first and most fundamental element of the roof system though is the waterproofing. Bauder Total Green Roof System (BTGRS) was selected as it provides robust and durable waterproofing with a life span in excess of 35 years, as validated by BBA Certificate 10/4744. The Plant E cap sheet has also been tested by the FLL to ensure long term root-resistance, making it ideal for use in conjunction with the BauderSOLAR G LIGHT system. The BauderSOLAR G LIGHT system is a unique way to combine rooftop vegetation with renewable solar energy. The PV panel mounting boards are held in position using the growing medium as ballast, meaning the waterproofing is not penetrated and therefore compromised. The mounting boards incorporate a water retention feature which allows a small amount of excess rainwater to be stored for short periods of time for the various plant species to feed from. The BauderSOLAR G LIGHT system’s unique mounting system lifts the panels above the vegetation allowing the plant life to grow freely and therefore qualify a greater area of the roof as biodiverse.In addition to the BauderSOLAR G LIGHT system, a blue roof was added to the build-up. Blue roofs are sustainable drainage solutions designed to manage stormwater on a flat roof to reduce water runoff rates and ease flash flooding and standing water in built up areas. The BauderBLUE Roof System attenuates water from a flat roof over a 24-hour period via a restrictive flow outlet. Calculations are carried out to determine the rate at which the water should egress the rooftop. This is determined by the local planning authority and is often set as low as 5-8 litres per second per hectare. With these calculations, Bauder can design each flow restrictorto meet the necessary runoff rate. For the Department of Civil Engineering, the main roof area of 1455.5m² required two flow restrictors, each with flow control holes to ensure the specified discharge rate of 0.77 litres per second was achieved. The maximum depth of water the roof is designed for is the H-max. When the water level reaches H-max, it will drain via the emergency overflow pipe. These overflow pipes are set at the same height as the H-max level. On this project the H-max was calculated to be 99mm. Although an unlikely scenario, this provision for a ‘once-in-a-hundred-years’ storm event will ensure that the structural integrity of the building is always preserved.Project challengesThe roof deck was constructed using a pretensioned concrete plank roof structure. Due to the large span of these planks, the dead load weight to the roof would be restricted. This being a blue roof with green landscaping and PV (a reasonably heavy build up), presented the issue of balancing the need of the roof design and the weight restriction of the supporting structure. To add to this challenging scenario, the pretensioned deck did not provide a completely flat finish. When installing a blue roof, a flat deck with no positive or negative falls is essential, as detailed in the 2018 update of BS 6229 – Flat roofs with continuously supported flexible waterproof coverings. To overcome this onsite challenge,the final deflection of the fully loaded roof was calculated and the concrete deck was screeded to give a flat finish.The resultBauder believes this project to be one of the first of its type in the UK to bring together so many rooftop systems in one space. Project management and clear communication was paramount in order to ensure a smooth installation. The Bauder project team consisted of green roof and solar PV product managers, area technical manager, technical design team, site technicians and approved installers for the waterproofing.With all the different elements being installed, green roof and solar PV product managers worked with our technical team to design the best possible PV array configuration for optimum energy generation whilst also qualifying for the maximum biodiverse area.Bauder site technicians worked closely with Bauder approved contractors, Voland Asphalte Ltd, to ensure works were kept to schedule and that a high quality of workmanship was maintained throughout.To ensure the landscaping is maintained, irrigation was installed by Access Irrigation Ltd. The system, Permadrip Pro, is a drip line irrigation system with anti-syphon design to resist clogging and pressure regulation. Due to the specialist nature of the irrigation system, Access Irrigation Ltd provided a bespoke design service.The result of this network of expertise was a multi-faceted support service for the client, specifier, main contractor and roofing and PV installers. System installedBauder Total Green Roof System (BTGRS)1 BauderPLANT E 42Green, 5mm torch-on root-resistant capping sheet.2 BauderTEC KSA DUOA self-adhesive, elastomeric, bitumen underlayer. This underlayer was used to ensure thorough sealing of lap joints in low temperatures when the roof was installed.3 BauderPIR FA-TETissue-faced flatboard insulation faced on both sides with aluminium foil to provide efficient thermal output.4 Bauder Super AL-ETorch-on air & vapour control layer. Once installed on the concrete pretensioned plank deck, it can act as a temporary waterproofing layer, allowing internal works to be carried out immediately which was a huge advantage on this new build project.BauderSOLAR G LIGHTThis BauderSOLAR G LIGHT system was a key factor in the specification of the project to meet the sustainability criteria specified by the client. 40 PV units were installed on the main roof area on the Departmentof Engineering. The forecasted energy generated for this arrayin its first year is 9.91MWh with a CO2 saving of 5.242 tonnes/a. BauderBLUE SR-B flow restrictorThe BauderBLUE SR-B flow restrictor is designed to be used in conjunction with a standard Bauder bitumen blue roof vertical outlet DN70. The flow restrictor is comprised of four parts; baseplate, overflow pipe, baseplate inner and baseplate outer seal. The polyamide baseplate fits within the 70mm vertical outlet, with the EPDM outer seal creating a watertight fit. The HDPE Overflow slots into the central hole of the baseplate with an inner EPDM seal preventing any leaks. The baseplate has a number (1-12) of 10mm restrictive flow holes bespoke to the project. The flow restrictor has no moving parts, hugely reducing the need for maintenance or risk of failure.

The new six storey HSBC building at No.1 Charter Square in Sheffield utilises ABG’s blueroof system to meet the National Planning Policy Framework and the site's Flood Risk Management Policy. Attenuation for the building is provided at roof and street level, comprising void formers constructed within the roof and streel level structures to temporarily attenuate storm water, before gradually releasing it over a number of hours via the ABG restrictor chambers.At street level the system was installed underneath the surrounding walkways and access routes to restrict discharge rates at ground level, including a large landscaped podium deck area above a service yard where heavy duty void formers were used in the event emergency vehicle access is required.

A prestigious four-star hotel in Surrey gets a stylish enclosed pergola structure to suit the ambience and scenery of the location. This historic hotel’s large paved terrace area with outdoor BBQ was only equipped with some tables and chairs, and so only used on dry days in the summer months. The hotel's event team wanted to create a new flexible outdoor space that could guarantee availability for bookings throughout the year, whatever the weather....

Client: Canary Wharf Group Consultant: Adamson Associates Architects Main Contractor: Kilnbridge Construction Ltd Main Products Used: Emseal DFR-2 SystemsWood Wharf Development is certified as a BREEAM Outstanding rated, sustainable mixed-use development that covers a 23-acre site. It consists of 6 individually designed building structures that provide 2 million square feet of curated workspaces and offices, more than 3,500 new residential homes and 500,000 square feet of retail space. The site is being developed as a new 5G and Wi-Fi-6 enabled, London District to include more than 9 acres of interconnected riverside leisure space with boardwalks, squares, and parks to create an oasis of urban green space. The new multistory building structures were designed with 50mm wide structural expansion joints between floor slabs to accommodate the high levels of thermal movement anticipated, as well as the vibrations from traffic and other loadings. These joints also had to minimise any noise transmission through the floors and provide a minimum of 2-hours fire resistance, which is a key reason the consultants selected the Emshield DFR-2 System as it could easily meet all these stringent requirements. In fact the innovative Emshield DFR-2 System can accommodate more than 100% joint movement capability and is CE Marked to EN-1366-4 for up to 4 hrs fire resistance. This unique Emseal solution also has the advantages of not requiring any potentially damaging mechanical fixings into the structure, as it is easily bonded into the joint, with access only required from above. 

The rotten timber sub-frame and deck of the walkway at Torquay harbour is replaced by composite decking supported by the strong and sturdy Ryno complete aluminium decking substructure system.

Accoya selected for the cladding & decking of the new Forest of Genetic Resource Department, Korea. To date, this project marks the largest wooden scale structure in the whole of Korea. Because of this iconic status the construction had to ensure that the most advanced materials such as Accoya were chosen. Due to the project being 4 storeys high Accoya was selected for its extreme durability & stability. Designed by IDS architects, Accoya was also chosen because of its natural & bespoke aesthetic. Due to Accoya’s light appearance the cladding could be painted to satisfy the designers requirements.

UNIZO office building CHALLENGE Dedalus Architects specified zinc for waterproofing the timber frame UNIZO office building in Eeklo. Not only for the roof, but also for the facade and bottom side of a unique construction detail. To be precise, waterproofing horizontally, vertically and even upside down! To entirely cover the structure however, appeared not to be possible when using zinc. If you opt to use this traditional waterproofing material a ventilated air space must be provided underneath the zinc covering. This of course entails an opening for ventilation purposes underneath the roof edge, if not, condensation will occur. In the case of a building where the facade has to connect seamlessly with the roof and the underside, leaving an opening is not a possibility. So, despite the attractive appearance of zinc, a waterproofing solution with this material was not an option. SOLUTION Thanks to their collaboration with roofer ALBITUM and previous experiences with RENOLIT roofing products, Dedalus Architects came up with a nice alternative: RENOLIT ALKORDESIGN standing seam imitation. A perfect solution for a difficult challenge. No ventilation needed, no connection problems, the same looks as a zinc roof and, above all, more cost effective! 

Meridian Integrated Systems Ltd. Approached NBB Outdoors on behalf of their estimated client L’Oreal Professional Products, to create a bespoke outdoor Multipurpose Storage Shelter, for their location in Bury.The principal project objectives were as follows:Enhanced Storage Solution: Meridian Integrated Systems were tasked with sourcing a secure yet functional storage solution for the Professional Product distribution arm of L’Oréal’s UK operations, based in Bury. The solution necessitated a roof and lockable gates and had to be tailored to fit within a specified area.Integration: The solution was required to fulfil the dual objectives of being functional and offering plenty of space. While also ensuring security to prevent unauthorised utilisation of the amenities by other businesses.Limitations and Restrictions: Given the retail nature of the business, it was essential that the chosen partner adhere to the predetermined installation timelines and operate within designated working hours. This adherence must ensure minimal disruption to the ongoing operations of the business.To meet L’Oréal’s exacting standards and requirements NBB Outdoors designed and implemented a unique Multipurpose Storage Shelter offering a range of tailored features:Custom Design: After a thorough site survey, a tailored multipurpose storage shelter measuring L5170mm x W1970mm x H2300mm was determined as the ideal solution for L’Oréal’s needs. The proposed dimensions not only met the required size criteria but also seamlessly integrated into the allocated space.Material and Construction: NBB Outdoors recommended and installed a Galvanised corrugated metal cladding roof and sides to the bespoke storage shelter, whilst proposing and implementing a brown 100% recycled plastic cladding to the gates. The choice of materials ensuring the storage solution will stand the test of time, with little to no maintenance.Security and Protection: Ensuring the multipurpose storage shelter remained secure was of the utmost importance therefore the shelter was finished with Fire Brigade (FB Key) locks.With careful attention to detail and strategic material planning, NBB Outdoors not only fulfilled but surpassed the customer’s expectations. Delivering a neat and contemporary industrial solution to the customer’s requirements.

The visitor centre roof has been set at 6 degrees to form an exact replica of two spitfire wings. This unique construction meant the need for superior materials, such as Protect 5000 Façade, TF200® and BarriAir, that could cope with the challenges of the design. The materials also needed to be resilient to cope with the harsh coastal conditions in the South of England.

The flat roof area at above the vast Guernsey Power Station had been suffering from water ingress as a result of failings in the existing EPDM membrane. Due to the expensive machinery housed within and the potential for widespread and costly disruption should the leaking continue.Guernsey Electricity turned to Sarnian Roofing Limited, a Polyroof approved contractor, to provide a rapid and effective waterproofing solution. The Protec System was specified, and work began quickly.The SolutionRemoval of the failed roof coverings to expose the concrete deck below began, and the BBA-approved Protec 20-year system was installed directly to the concrete. Due to its RapidCure technology, the system cures within 30-60 minutes, meaning less disruption for the client.The Protec System provides an flexible and seamless membrane that eliminates the risk of water ingress around penetration points common in industrial unit roofs. As the system is cold applied, there are none of the safety risks associated with the open flames and hot torches used with traditional roll-applied systems.Polyroof’s reputation has been built on the high level of technical support provided to clients before, during and after every contract.We like to work closely with our clients from the very beginning of a flat roofing project right through to completion and throughout the lifespan of the roof. From our experience, this is the best way to guarantee that all aspects of the roof are finished to the superior standards that our clients expect.

Roof and facade cover... CHALLENGE For the design of a youth centre a Belgian architect wanted to have a fully homogeneous and waterproof cover for the roof and the facade. This envelope technique needed to be combined with a more ecological and aesthetically pleasing green wall design. SOLUTION For the waterproofing of the roof surface a standard RENOLIT ALKORPLAN roofing membrane was used. For the facades the architects opted for a RENOLIT ALKORSOLAR fixing system as the base to attach the final greenwall system. As the roof and the wall covering (waterproofing) are the same material there were no jointing issues. The whole building has been covered with RENOLIT ALKORPLAN roofing membrane. The facade details were similarly accomplished as standard roof details and RENOLIT ALKORSOLAR profiles were used to fix the rain water pipes from the roof.

Metrotile is often utilised as a ‘problem solver’ material, chosen when a development needs a new roof that not only requires all of the security and aesthetics a roof should provide, but can also be installed rapidly - this is true of both new-build and refurbishment works. This lead to specification on this exciting Bristol-based office development (more at link)

Beauty & Heritage - Marley’s Hawkins Fired Sienna clay plain roof tile, the perfect specification choice for a new development in Warwickshire. Properties had to fit seamlessly into the surrounding landscape, while also meeting strict planning regulations. Keith Greenall, MD for Greenall Construction, “The mock Tudor architectural style, incorporating natural materials meant we wanted to find a roofing solution in keeping with the look we had established. “The development required a clay tile perfectly matching the aesthetics within the village & the planning committee were happy the clay material suited the ambience & style of the development & local area.”

Comprising of nine shops and several residential flats, properties 29-47 High Street Polegate required a full roof refurbishment after complaints of water ingress into the residential buildings. Proteus Waterproofing conducted a thorough survey which revealed that the existing roof build up, made up of a timber deck and 2-layer felt, had been previously repaired but was now at the end of its serviceable life.Being a residential building with a combustible deck, protecting individual properties from internal fire spread was a key consideration. Compartment walls were identified allowing Proteus Waterproofing to provide a solution that would meet regulatory guidance relating to the junction of compartment walls and roofs in Approved Document B whilst meeting the needs of the client.Proteus Waterproofing specified their robust reinforced bitumen membrane range of Proteus Pro-Felt®, including a bespoke hybrid insulation approach, where instead of a full replacement consisting of entirely non-combustible insulation, a scheme was designed to meet the requirements above and either side of the compartment walls, offering the client the most cost-effective solution possible that would also mitigate any unnecessary increase of weight loading elsewhere on the roof.High Performance WaterproofingThe waterproofing and existing deck were stripped back and re- decked with 18mm plywood. When removing the existing waterproofing, our approved contractor, carefully recorded the exact location of the party walls as no drawings of the upper story flats were available.Proteus Pro-Felt® SA AVCL was used as a vapour control layer to allow for the application of the hybrid combination of 150mm Proteus Pro-Therm PIR insulation and 150mm Proteus Pro-Therm Mineral Wool insulation. A thermal calculation was undertaken to ensure that the final result met the requirements of Part L of the National Building Regulations. These were both adhered with Proteus Pro-Bond Foaming Adhesive. Proteus Pro-Felt® SA Underlay Plain was laid and finished with Proteus Pro-Felt® Ultima Plus Fireguard Mineral Capsheet, providing the client with a fully waterproofed Part B and Part L compliant roof, guaranteed for 20 years.Proteus Waterproofing worked closely with the Proteus Approved Contractor, to ensure the project was delivered to a high standard.Health & SafetyWhen working on occupied buildings, safety is always of utmost importance, as well as keeping disruptions to a minimum.

11 Freebournes RoadBauder reinforced bituminous waterproofing system with BauderSOLAR FSynopsisA large derelict warehouse located in Witham has undergone major renovation to transform it into a storage centre for Essex County Council that will assist its services and benefit the local community. The refurbishment works were designed and project managed by Lambert Smith Hampton on behalf of the client, who wanted the building to act as a benchmark for sustainability with the roof playing an integral part in achieving this through the addition of solar panels.Bauder Building BoardProject Name:11 Freebournes RoadLocation:Witham, EssexRoof Size:5,200m²Client:Essex County CouncilProject Manager:Lambert Smith HamptonApproved Contractor:Acclaim ContractsPV Installer:CJ SolarEnvironmental focus:Solar PVThe specificationWorking closely with the client, Bauder performed a comprehensive roof evaluation survey to identify the full extent of water ingress being experienced and to confirm the suitability of adding solar. The bespoke survey report highlighted that the roof needed to be stripped back to its original deck, before being waterproofed with over 5,200m2 of Bauder’s reinforced bitumen system by Acclaim Contracts. 588 solar PV modules were then fitted onto the roof by electrical installer CJ Solar, enabling the client to generate at least 134.70 Megawatt Hours of solar power each year. Products appliedBauderSOLAR FIntegrated photovoltaic system, where the modules and the substructure are combined to form a single unit, which is secured to the roof without any penetration of the waterproofing or roof deck. System installedReinforced Bitumen Membrane System1 Reinforced bitumen membraneTorch applied, elastomeric bitumen capping sheet2 BauderPIR M 60Rigid urethane foam insulation faced on both sides with aluminium foil.3 BauderPIR FA-TETorch applied air and vapour control layerAdvocacyJulian Sanchez, Commissioning Delivery Manager for Essex County Council: “We actively look for opportunities to implement renewable energy and knew that this storage facility lent itself well to PV retrofit.

Container City is an outstanding example of upcycling architecture in the London Docklands. The buildings are constructed from old shipping containers that have been refurbished and then fixed and welded together, creating an innovative modular building solution that houses offices.The roofs had been waterproofed with an EPDM membrane as part of an inverted roof design, however due to failings within the roof coverings leaks were occurring.It was also felt that the inverted roof insulation was unable to provide satisfactory thermal performance, leading to excessive fuel bills during winter. The architect responsible for finding a solution used Polyroof’s Solution Finder Tool to quickly find a recommendation for improving the thermal properties whilst providing long-term waterproof protection. Equipped with the key information needed, the architect specified the Protec Warm Roof System for the roof refurbishment works.Polyroof Technical Services carried out a full technical survey of the existing roof to identify all existing issues and provide a full set of recommendations. One of the key drivers for the refurbishment was the ability to easily access the roof membrane to carry out regular cleaning and maintenance works, so the specification included for converting the roofs from an inverted roof to a warm roof design.Polyroof Approved Contractor A R Roofing Ltd began by stripping away the old inverted roof components and the failed EPDM membrane to expose the metal roofs of the containers below. A self-adhesive vapour barrier was then laid onto the metal decks and Polyroof RES Insulation (T&G) was bonded on top using PU adhesive. Lastly, the Protec system was laid direct to the insulation boads to create a seamless, smooth and long-lasting finish that came with a 20 year insurance backed guarantee. This striking piece of upcycled architecture now has a roofing solution to match the innovation behind its creation.

To create a Blob... CHALLENGE For the design of a Texaco service station on the highway near Antwerp the architect decided he wanted to create a Blob (Binary large objects) architectural design. The service station consists of three functional lobes that together look like an oil stain. The actual gas stations are covered with 4 lobe-shaped canopies. To accentuate this futuristic design the architect wanted to create liquid formed shapes in a metallic look. As the walls of the main building were planned using a polurea metallic finishing coating the architect sought a suitable compatible material to finish the rest of his Blob roof surfaces. SOLUTION Synthetic roofing membranes are the most flexible materials on the market and are suited to waterproof almost all possible roof shapes. For this particular project the silver coloured RENOLIT ALKORPLAN membrane was the best solution. This silver membrane is produced with a protective coating creating a roofing membrane that is easy to clean. The RENOLIT ALKORPLAN Metallic membranes combine excellent durability with added aesthetical appearance.

Project descriptionDixons Academies Trust is a well-established multi-academy trust that aims to challenge educational and social disadvantage in Yorkshire and the North West.The trust transforms schools into safe and high-performing learning environments, enabling students from all backgrounds to realise their potential and maximise their opportunities after school.Alpha Roofing Systems was brought in to refurbish two roof areas at Dixons Croxteth Academy in Liverpool after the existing waterproofing failed.A number of complex challenges arose from the start; after stripping back the aged and failed single ply system, Alpha identified a water-saturated bituminous roof beneath, which also overlaid the original asphalt waterproofing.The excess weight imposed on the roof from the multiple, heavily saturated waterproofing systems led to cracking and depressions in the deck, as well as rusting of reinforcement within the structure.This meant that, before installation work could even begin, many hours of labour were required to remove the top two waterproofing layers to expose the original asphalt. What’s more, this work had to be undertaken both during term time and a period of heavy rainfall.Solution and installationAfter close consultation with their IKO business manager, Mark Taylor, the Alpha team selected the IKO ULTRA Prevent 25 waterproofing system for this project.To adhere to Department of Education requirements, a 35-year durability statement was necessary, so the long-lasting, durable finish offered by the IKO ULTRA Prevent system was ideal.Challenges continued to come thick and fast throughout the project; after stripping the roof back to the asphalt waterproofing, a large expansion joint was found near the clerestory window. Tapered designs were subsequently adjusted to accommodate.30 tonnes of waste material – primarily due to the uplift of the previous failed waterproofing systems – also had to be removed from the roof over the course of a week.Furthermore, complex design variables meant that Alpha could not fully determine the existing roof falls until the roof had been sufficiently exposed. Working closely with the IKO technical team, design information and solutions were identified to keep the project on track.To complicate matters further, Alpha was also required to carry out this extensive work during active teaching time. This presented not only additional health & safety considerations but also the need to minimise disruption.With a stringent construction phase plan and regular active monitoring, the project was completed with a zero incident/accident rate and excellent feedback from the client on Alpha’s approach to safety.Despite a number of hurdles and complexities to overcome, Alpha Roofing Systems delivered the project ahead of time and within budget, providing a low maintenance, long-lasting roof for Dixons Croxteth Academy and a satisfying outcome for all involved.

Project descriptionDixons Academies Trust is a well-established multi-academy trust that aims to challenge educational and social disadvantage in Yorkshire and the North West.The trust transforms schools into safe and high-performing learning environments, enabling students from all backgrounds to realise their potential and maximise their opportunities after school.Alpha Roofing Systems was brought in to refurbish two roof areas at Dixons Croxteth Academy in Liverpool after the existing waterproofing failed.A number of complex challenges arose from the start; after stripping back the aged and failed single ply system, Alpha identified a water-saturated bituminous roof beneath, which also overlaid the original asphalt waterproofing.The excess weight imposed on the roof from the multiple, heavily saturated waterproofing systems led to cracking and depressions in the deck, as well as rusting of reinforcement within the structure.This meant that, before installation work could even begin, many hours of labour were required to remove the top two waterproofing layers to expose the original asphalt. What’s more, this work had to be undertaken both during term time and a period of heavy rainfall.Solution and installationAfter close consultation with their IKO business manager, Mark Taylor, the Alpha team selected the IKO ULTRA Prevent 25 waterproofing system for this project.To adhere to Department of Education requirements, a 35-year durability statement was necessary, so the long-lasting, durable finish offered by the IKO ULTRA Prevent system was ideal.Challenges continued to come thick and fast throughout the project; after stripping the roof back to the asphalt waterproofing, a large expansion joint was found near the clerestory window. Tapered designs were subsequently adjusted to accommodate.30 tonnes of waste material – primarily due to the uplift of the previous failed waterproofing systems – also had to be removed from the roof over the course of a week.Furthermore, complex design variables meant that Alpha could not fully determine the existing roof falls until the roof had been sufficiently exposed. Working closely with the IKO technical team, design information and solutions were identified to keep the project on track.To complicate matters further, Alpha was also required to carry out this extensive work during active teaching time. This presented not only additional health & safety considerations but also the need to minimise disruption.With a stringent construction phase plan and regular active monitoring, the project was completed with a zero incident/accident rate and excellent feedback from the client on Alpha’s approach to safety.Despite a number of hurdles and complexities to overcome, Alpha Roofing Systems delivered the project ahead of time and within budget, providing a low maintenance, long-lasting roof for Dixons Croxteth Academy and a satisfying outcome for all involved.

Union Wharf is a two tower residential development in Greenwich, London. A 23-storey Roof garden makes the most of the breath-taking views of the London skyline.Designing and specifying products for a 23-storey high terrace comes with some key issues which must be addressed. One of which, the Terrafina decking overcame due to its easy clip system making it a doddle to install and overcome this problem.Another, was to ensure a solid base for the artificial grass and planters to be fixed to. This was however, something Raaft had planned for and the Floor structure panels was an easy solution to this.

Metrotile has often stated that their Lightweight Steel Roofing systems can go head to head with ‘traditional’ materials aesthetically, and Gorse Hill School is a fine example of this statement in action.Gorse Hill is unique as it required a partial refurbishment. Some, but not all of the blocks roofs where in urgent need of repair. For these roofs, Metrotile’s classic ‘Roman’ profile was specificied as its contoured design matched the concrete Roman tiles that remained on some of the buildings.The finished product, is a fine example of old meeting new with brilliant results. Another important factor involved with the specification of Metrotile was the need for a secure roofing solution.

Metrotile Lightweight Steel Roofing now adorns the rooftop of the Bryn Bach Country Park visitor centre near Tredegar, South Wales. Installed to replace the previous leaking so-called ‘traditional’ material roof, that was allowing water ingress in the cafeteria area, the new Metrotile roof has given the facility a new lease of life and an attractive makeover, in time for the busy summer season. Some 2,600 of Metrotile’s vandal proof Slate 900 profile, each covering almost half a square metre but weighing just 4.6kg, now cover the 1,300 square metres roof of the visitor centre.

The meticulous refurbishment of this Grade II Listed landmark provides a stunning range of luxuriously specified apartments. Buzon UK were specified to install the PB pedestal system to support two large (220sqm and 180sqm) hardwood decked outdoor terrace areas. This project was particularly challenging due to the many curved planters, upstands, steps and seating areas but the PB pedestal range can be adjusted from 28 to 965mm to create different height levels and the ergonomic design makes it easy for accurate and effective installation. The finished private roof terraces provide residents with the perfect outdoor space.
