"roofing membranes"

The Blackheath Hospital, a private hospital made up of Victorian houses that from the classical façade of the building required a new waterproofing membrane to the plant room roof, after reports of water ingress to the building below.

Gloucester Transport Hub Bauder Thermofol PVC single ply waterproofing system SynopsisThe replacement bus station and regeneration of the surrounding area has created a unique and distinctive city centre building for the town. The design connects with Gloucester’s Roman heritage and association with aviation. The innovative roof design incorporated a canopy intended to reflect an aircraft wing that required a lightweight waterproofing and renewable energy photovoltaic (PV) solution.Bauder Building BoardProject:Gloucester Bus StationLocation:GloucesterProject Type:RefurbishmentRoof Size:1520m²Constructor: Kier Group PlcApproved Contractor:Kovara Projects LtdThe specificationThe Bauder Thermofol PVC single ply waterproofing system with the BauderSOLAR F PV solution met the brief precisely without compromising the aesthetics of the roof. This combination of Thermofol PVC single ply waterproofing system and BauderSOLAR F PV delivered a high quality, strong, energy efficient flat roof.This system was selected for the project because of its lightweight properties which complemented the deck and roof design. Light grey was chosen to reflect the colour of the cladding as the aesthetics was a key objective for the client.The OMG Rhinobond induction welding system was specified as the installation method which provided multiple advantages to the project, not only saving time and fasteners, but also optimising the field fix pattern of installation and ensuring that the load on the roof was spread between the induction welding plates. Products appliedBauder Thermofol U15 FR MembraneA high grade virgin polymer Thermofol PVC membrane ensures the optimum membrane characteristics to deliver high performance and a BBA stated life expectancy in excess of 35 years.BauderSOLAR F An aerodynamically optimised system for flat roofs using framed modules and mounting units, securing them to the roof using membrane-to-membrane welding techniques. This installation method means that the roof is not compromised by penetrations of fasteners or is it ballasted.Project challengesThe design of the Transport Hub and city centre location proved to be the key challenge to this project. The unusual roof configuration required a bespoke insulation scheme using BauderPIR M, an efficient rebated PIR insulation board, in order to achieve the required U-value of 0.18W/M²K.The deck configuration equally made the installation of the Bauder Thermofol PVC waterproofing system complex with the perimeter zone having to be carefully marked in compatability the wind calculation which included measuring factors such as wind speed, altitude, direction and exposure. Bauder and Kovara Projects were required to work closely together to ensure all criteria of the wind calculations were met. 40 modules of the lightweight BauderSOLAR PV solution were installed on the west side of the Transport Hub’s roof.The location of the project, Gloucester city centre, presented logistical challenges. Delivery of the roofing products had to be carefully scheduled and managed to avoid creating congestion in the area.The resultThe installation required constant co-operation and communication to embrace the live site operations within the restricted city centre location whilst allowing the bus station to remain fully functional. The roofing contractor delivered a superior standard solution and any complex issues that arose during the project were resolved promptly and collaboratively.System installedBauderThermofol PVC single ply waterproofing system  1 Bauder THERMOFOL U15 FR1.5mm polyvinyl chloride membrane (PVC) reinforced with a pre-coated polyester cross-weaved matting for mechanically fixed installations. 2 BauderPIR MThis efficient tissue-faced flatboard insulation has been specially developed for use within Bauder single ply systems. 3 BauderSYN DB-PE 100A blue, polyethylene air and vapour control layer.

Den CourtBauder Thermofol single ply waterproofing systemSynopsisConstructed in 1977, Den Court is a large retirement home made up of 24 flats in the small town of Lochgelly in Fife. The regeneration of the sheltered housing by Fife Council involved the demolition of part of the building as well as replacement windows and doors, landscaping and a new car park.Bauder Building BoardProject:Den Court Care Home, CardendenLocation:Lochgelly, Fife, ScotlandProject Type:RefurbishmentRoof Area:1200m²Specifier:Fife CouncilApproved Contractor:Greenroof UKThe specificationThe client was clear that lead effect rolls were essential for this projects roof. In order to achieve this whilst keeping with the original roof of the building and with the other buildings of the area, Bauder’s Thermofol PVC system was specified and approved contractor Greenroof (UK). The resultDuring installation, the approved contractors hand-crafted over 2,000 linear meters of timber battens wrapped in the Bauder THERMOFOL U15 Fleece Back waterproofing membrane. These were then installed on to the 1200m² roof area.Thanks to the hard work and craftsmanship deployed by the approved contractor and the high-quality products used on the project, following a roof inspection from an expert Bauder Site Technician and a leak test, Bauder was able to issue a 20-year product and workmanship guarantee to the roof. System installedBauderThermofol single ply waterproofing system1 Bauder THERMOFOL U15 V FR1.5mm fleece-backed reinforced PVC membrane2 BauderPIR MTissue-faced flatboard insulation3 BauderTEC KSDElastomer bitumen air & vapour control layer, self-adhesive membrane

Emma House, Romford, a residential apartment block built in 2007, needed a new waterproof membrane for the entire roof area after the single ply membrane, installed just 10 years earlier, had failed. The specification by our clients asked for a cold applied system to be used during the refurbishment to minimise disruption to residents, while providing a permanent waterproofing solution.The ChallengeCore samples taken of the roof build-up showed there had been extensive water penetration which required urgent remedial action. Impossible to repair, the complete roof system had to be stripped back to the roof deck by Proteus Waterproofing’s approved contractor. The approved contractor installed a new Proteus Pro-System® BUR (built up roof system) incorporating Proteus Pro-Therm insulation, to provide a new seamless roof – an area of some 150 square metres – offering a 20 year guarantee.Why Proteus Pro-System® was specifiedProteus Pro-System® was installed using no heat, providing a seamless waterproofing membrane on completion. Proteus Pro-System® is a high performance, seamless and cold-applied waterproofing membrane for flat and pitched roofs. It cures to provide completely seamless waterproof protection and has excellent thermal and UV stability, making it suitable for use in all climates.Proteus Pro-System® does not brittle, deteriorate or discolour with age. It uses atmospheric moisture to trigger its cure process and unlike conventional polyurethane systems can cure under water, without gassing or foaming. It also becomes resistant to rain damage and may therefore be applied in relatively poor weather, without any subsequent loss of performance or durability – making it ideal for Emma House.About Emma HouseEmma House consists of 14 one-bedroom and 19 two-bedroom apartments just minutes away from the centre of the market town of Romford, which offers shops, services and a wealth of bars and restaurants. When first built in 2010, Emma House offered young professionals an opportunity for affordable housing close to London and has remained at the forefront of the property market in Romford ever since.

The Olympic Stadium renovation had acoustic performance as a central goal to obtain. ROCKWOOL's solution involved the installation of an acoustically insulated membrane roof, featuring ROCKWOOL HARDROCK® Multi-Fix (DD) and ROCKWOOL Acoustic Infills.

As a company passionate about UK manufacturing, Aston Martin’s choice to work with Polyroof - the only independent UK manufacturer of cold-applied liquid systems - was a natural one.The new roofing system had to be cold-applied to eliminate the risk of accidental fire during installation. New insulation was also desirable to further improve the thermal performance of the roof. It was essential to reduce disruption to the operations of the facility, meaning any new system must be rapid to install with the existing roof predominantly being kept in place.After leaks were reported, The findings of Polyroof’s survey were presented to Aston Martin in the form of a bespoke specification, where the Protec Warm Roof System was the recommended solution. Core tests taken during the inspection had revealed that despite the leaking through the existing PVC single-ply membrane, the existing build-up of 60mm PIR insulation was found to be dry and in sound enough condition to be retained as the base for the new roofing system, saving the client time on the project.It was also identified that the current insulated roof configuration was missing a Vapour Control Layer, meaning the roof was at risk of condensation issues. This problem was designed out by the installation of 120mm Polyroof RES Insulation above the existing single-ply membrane, which was made good to form an effective vapour control layer.By creating a “hybrid” roof with double the insulation above the vapour barrier than below, the risk of condensation was eliminated and this was demonstrated by analysis conducted on the proposed build-up.To eliminate the standing water issues, sumps were placed around the existing outlets, greatly improving their drainage capacity, and offering a highly cost-effective solution when compared to the need to alter the falls of the roof.Polyroof Technical Services visited site regularly to advise and assist architects, specifiers and contractors in all aspects of the project.The finished roof provided a seamless and extra-tough waterproof membrane that was supported by the trusted Polyroof Accredited System Guarantee, with a separate insurance-backing scheme provided at no cost to the client. Aston Martin Lagonda now have the peace of mind that the roof above this landmark facility will be leak-free for decades to come. 

Spanning an impressive 8,500m2, the three-storey building makes a striking centrepiece on the water’s edge. With its BREEAM requirements, waterfront position, and proximity to the coast, it was essential that the building’s roof be designed and installed to meet sustainability criteria, whilst being watertight and robust to withstand the elements. As the system needed to exceed a lifespan of 20 years in a coastal region, Sarnafil specified its thickest membrane with a 25-year guarantee – a 2mm membrane, Sarnafil HD, to withstand the elements on the main field area which it currently is doing extremely well.

The Big Chill, a bar in King’s Cross, was creating a public roof terrace on an existing structure. The deck was complicated with many changes of level and multiple objects present. A single ply membrane was installed. Paving and decking was required. Adjustable pedestals were laid directly onto the surface and their heights altered so that the upper surface of the 50mm paving slabs and the 125mm decking frame would be level. Nothing penetrated the membrane and the weight tolerance of the ASP and TD pedestals meant even very heavy traffic on a public bar was accommodated.

The National Gallery and the Science Museum - two of London’s major and iconic visitor attractions built more than 150 years ago – required an extensive programme of roof upgrades and maintenance. Working with the National Gallery since 1995, the roof replacement and thermal upgrading project has seen in excess of 12,000sq m of Sika Sarnafil membranes installed, together with insulation, roof lights and walkways in a series of over 30 completed projects – including the complete Sainsbury Wing in 2008.

In a complex new build roofing project that was deemed almost impossible, Contour Roofing stepped up to the challenge with a Sika Sarnafil membrane. With truly stunning results, the project impressed the judges of the prestigious NFRC UK Roofing Awards, winning the Single Ply category. In partnership with Sika Sarnafil, Contour quickly presented a new bespoke specification; an adhered system using Sarnafil G410-15ELF Lead Grey with a polyester fleece backing as the main roof sheet for a flawless result and Sarnafil G410-15EL Lead Grey for all the detail work flashings.

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.

Heathside and Lethbridge is one of London’s biggest estate regeneration programmes, and is planned to be carried out over six phases. The regeneration works being undertaken by Family Mosaic and the London Borough of Lewisham are transforming the estates into an attractive mixed tenure development, with over 1200 high-quality private and affordable homes.Phase three saw 218 homes built including 102 homes for social rent, the rest being for sale and shared ownership. Phase 4a and 4b saw 236 new homes built.Shield Membranes supplied the waterproofing, insulation & external finishes to all external areas with great efficiency, making sure everything was on site as and when it was required in order to keep each phase on track.

Financed by county council capital funds, Northamptonshire County Council undertook a multi-million pound remedial works programme on a number of schools originally built in the 1960’s and 1970’s. All of the buildings were suffering from some degree of water ingress, and the roofs needed to be brought in line with current building regulations for improved thermal performance. Sika Sarnafil’s specialist roofing contractors installed over 50,000m2 in light and lead grey of G410-18EL single ply membrane to the school roofs.

The Joseph Black Building, found in the King’s Buildings Campus at the University of Edinburgh, houses the School of Chemistry and is one of the oldest buildings on the campus. But its existing copper roof covering had come to the end of its natural life. Sika Sarnafil’s flagship Sarnafil Plus refurbishment offer was the perfect solution for this project. Sika Sarnafil Membrane S327-15EL in Patina Green was chosen to replace the old roof covering, as the local authority planning department advised that this product was an acceptable replacement for the original copper roofs on the listed building.

The Ascent Up and On step unit was specified to create a safe means of access between different roof levels external to the roof of a city centre residential block. The building is has a single ply membrane roof covering and it was the clients desire not to penetrate the roof; hence the step over / stair unit is supported on rubber spreader feet which provide a non-penetrative support solution. The stair unit is designed in accordance with BS EN ISO 14122-1:2001 + A1:2010 and Building Reg Part K:2013 and manufactured following 1090 factory production control procedures.

When it comes to residential, commercial or any structure below ground, waterproofing is a critical component within the construction process for protecting and preserving a building. A poorly designed or installed waterproofing solution can fail leading to significant implications on the structure itself.Delta Registered Installers, Abtech (UK) Ltd were called upon to give assistance on a particularly technically complicated project where approaches to waterproofing design and installation had been incorporated, however the system had failed. For a great remedial waterproofing outcome, seek assistance from an experienced waterproofing company to inspect your site and carry out the remedial work.The property when built had a Type C, cavity drain membrane systems incorporated (not a Delta System), however there was no basement drainage incorporated into the design to manage water ingress.In principle a Type C, drainage system is a water management system. The Type C system is used to control water ingress once it has penetrated the structure.  Moisture or running water travel behind the Type C membrane within a controlled drainage system. A Type C System isn’t classified as a barrier but provides protection by means of water management. For a Type System to be successful a suitable drainage system is required to collect and discharge water ingress to a suitable and safe evacuation point (either by natural forces or a mechanical pump system).When correctly installed, groundwater drainage channels effectively relieve hydrostatic water pressure in the below ground structure. They are installed below flooring membranes at the floor/wall junction.

The Ascent Aluminium fixed ladder access system was specified to create a permanent safe access route to the roof for maintenance personnel. As the ladder provided access between two membrane roofs there was a requirement to specify non-penetrative support feet at both head & base. Hoops were provided throughout for fall protection and the ladder was designed in accordance with BS 4211:2005+A1 2008 and manufactured in accordance with CE 1090 factory production control procedures.

The Gunnery, Kent is a unique and interesting project. Delta Membranes were appointed as Waterproofing Designer to transform an unused fort/home in Kingsdown, Kent. The building was situated 92ft on a cliff edge. The Gunnery was originally a military base with extended underground rooms and thought to have ‘secret rooms’ underground. The building had suffered from fire damage as well as vandalism over the years and had been left to ruin. During a site visit various considerations were given to what Delta product would be best suited to the job, given the restrictions imposed by the existing structure.

With previous roof re-coverings proving problematic, two key requirements were highlighted, building the thermal performance to help save energy, and improving robustness, to mitigate damage caused by vandalism. The architect worked closely with Sarnafil to ensure the chosen roofing products provided the required detail, specification and performance. A Sarnafil HD bonded system was specified guaranteeing a high quality and durable roof. By combining the thickest single ply membrane available – 2mm – and the robust insulation board – SarnaTherm HD – the Sarnafil HD system offered a long-term, resilient and well-insulated roofing system with very low thermal conductivity.

The project comprised the construction of Newcastle’s tallest building, Hadrian’s Tower on behalf of The High Street Group. Following a 30-month build programme, the 26-storey luxury high-rise mixed-use development in the heart of Newcastle was handed over, with more than 60% of the apartments already sold or let at the point of handover.The development included 160 units which comprised a mix of studio, one and two-bedroom apartments and three spacious three-bedroom penthouse suites. Hadrian’s Tower offers 134,000 sq ft of modern living space a 4,300 sq ft rooftop sky bar and coffee house on the 27th floor.The scheme has redeveloped and in turn transformed the dilapidated city centre brownfield site into a high-quality pedestrian route into the city centre.Shield Membranes supplied numerous products and systems in order to waterproof, insulate and finish all external areas.

An old block of apartments in Gt. Yarmouth getting a low carbon Retrofit for a higher, cleaner living standard and reduced energy bills. Passive Purple has been used externally on this huge scale block of apartments. with no margin for error and tricky details throughout, a liquid applied airtight membrane was the only way going forward. The building was being insulated externally and getting a whole new façade from render to aluminium panels. With the residents still inhabiting the building this had to be done quickly and easily with maximum results. Being a liquid applied airtight membrane, any cracks, gaps, and service penetration leaks in the existing building fabric quickly became thing of the past. That and the hundreds of Panel brackets being installed to support the new façade going on, this Retrofit had multiple penetrations and tricky details. Making good of the building fabric and awkward brackets with a near on impenetrable adhesion, Passive Purple made fast work of this great conversion, impossible for any other method. Being in liquid state on application, Passive Purple can be applied onto most/any surface (See data sheets for more information) and will find its way into all the unseeable tiny gaps and cracks all buildings will undoubtably have. Like this old pebble dashed façade, any rough, uneven and awkward areas are no longer an issue, our products simply flow into these areas. We also have the fibre reinforced Passive Purple brush, used on this job to prepare the brackets by filling the larger gaps between that of the bracket and the existing wall and also the large penetrating bolts. A huge win and demonstration of the power of liquid products by Intelligent Membranes.

The Proteus Waterproofing roof survey carried out found the existing flat roof system to be saturated. The existing roof build-up needed to be stripped back to the roof deck, with the main challenge of the roof refurbishment being the low up-stand heights available to the penthouses.The project required a flat roof system manufacturer involved at the initial roof survey and specification design stage, followed by the manufacturers technical back-up to assist with unforeseen and unexpected situations to ensure a successful installation of the new roof systems.High Performance WaterproofingThe terrace roofs above hated spaces demanded a waterproofing system with BBA certification. The fully bonded and seamless Pro- System® Plus was selected for its high performance and low odour, in conjunction with Proteus Pro-Therm Insulation to improve the roofs thermal performance and reduce the existing condensation risk.The flat roofs that were not above heated spaces required Proteus Pro-System® Plus low odour, seamless waterproofing overlay. Proteus Waterproofing worked closely with the Client and the Proteus Approved Contractor, which also acted as the Main Contractor, to ensure the installation complied with the specification design.Health & SafetySafety on construction sites is always of the utmost importance, as well as keeping disruptions to other trades to a minimum. Proteus Pro-System® Plus was selected for its high performance, low odour, phased cold installation and seamless waterproofing.Long Term Performance​Proteus Pro-System® Plus creates an elastomeric, seamless, cold applied waterproofing membrane. The Proteus Pro-System® Plus system can include warm roof insulation. The membrane does not become brittle with age, is BBA Certified with a durability statement of at least 30 years.

FOAMGLAS® Tapered T4+ (Slab)Design Architects: Renzo Piano Building WorkshopExecutive Architects: Adamson Associates, LondonMain Contractor: Mace; Roofing Contractor AC PLCConstruction: 2012Application: Warm Roof - FOAMGLAS® Tapered T4+ (Slab )Finish: Bitumen membranesFOAMGLAS® provided the ultimate solution for the roof maintenance platform of The Shard at level 75.Its light-weight and high compressive strength enable regular maintenance to be carried out without risk of surface damage.At 310 m, Shard Tower is one of Western Europe’s tallest buildings; exposed to extremes of temperature & the revolutionary structure sways up to 50 cm in high winds.The building maintenance platform on level 75 islocated directly above the viewing galleries, and essentially forms the Shard’s roof. To shed water, the flat metal platform required an insulation with a tapered top surface.In this extremely exposed location, and with significantloads upon the platform, a truly reliable solution was needed. FOAMGLAS® insulation combines compressive strength, long-term insulation performance.Using their "in house" CAD systems, FOAMGLAS® designed a bespoke Tapered Insulation system. Taking full advantage of its low coefficient of expansion, and to eliminate thermal bridging, FOAMGLAS® and its membranes were adhesive bonded onto the metal structure. The unique ability of FOAMGLAS® to withstand high compressive loads ensures regular maintenance work can be safely carried out without damage to the insulation or the membranes.Adamson Architects commented on this project: "FOAMGLAS® has proved itself to be the ultimate solution for the difficult loadbearing areas of the Shard. Specifying cellular glass insulation ensured complete integrity and performance in key areas of the Shard Tower".

The National Trust visitor centre at Tarn Hows in the Lake District is set in a protected Site of Special Scientific Interest (SSSI). EPDM was specified for the roof because of its environmentally friendly credentials which have the backing of Greenpeace. Hertalan roofing products were chosen because of ISO9001/14001 and BBA certification. The membranes were a combination of factory vulcanised sheets and easy weld rolls which were installed in accordance with strict FLL/GRO guidelines. The specification for the green roof insisted on local species of sedum and had over 2000 plug plants installed into 150mm deep recycled growing substrate.

The O2 arena's roof needed state-of-the-art acoustic engineering to eliminate virtually all nuisance ambient noise (bass thumping) outside the arena contributing to fantastic acoustics inside the structure.The complex roof design featured several layers of different density barrier materials to deaden even the lowest bass frequencies, all carried on special acoustic deck structures. The structural deck troughs were filled with ROCKWOOL RW4 insulation, with ROCKWOOL Acoustic membrane over and a 50mm Rigidal intermediate deck.

Overcoming the challenges facing the Council was key to the success of the project. These were health and safety, time, cost, and aesthetics. A cold applied system was used to secure the membrane, eliminating the need for naked flames on the roof. Norwich City Council commented, “The Castle Museum houses collections of national importance, not only did we have to consider the safety of staff and the public, but also the historic collections whose home is beneath the rotunda roof. The need to elimate hot works on this project was a huge issue in specifiying the products to be used.”

The £230m Princesshay Shopping Centre, in Exeter, officially opened to the public in September 2007, as part of the city’s biggest ever regeneration project, with over 70 shops, cafés and restaurants. The roof of the centre, installed when the building was constructed, had caused various problems throughout its life. A Sarnabar system in Lead Grey was chosen, with a T fleece between the composite deck and the mechanically fastened Sarnafil S327-18EL membrane. On a smaller roof with a plywood deck, Sarnafil G410-ELF, an adhered system with a fleece backing, was specified.

This was a large roof terrace on a private domestic project. The area was flooded and had needed to be re-laid with waterproofing and a significant fall constructed into the deck to allow the often considerable amounts of rainwater to escape the roof deck. The contractor asked Wallbarn for a suitable but cost effective solution so we recommended Wallbarn 9mm rubber supports along with levelling shims. The area was re-waterproofed in the inverted waterproofing method, the membrane being covered with rigid insulation boards and a loose laid geotextile fabric to act as a separation layer .

George Abbott SchoolBauder Thermofol single ply waterproofing system with Bauder Euroglaze rooflightsSynopsisLocated in Guildford, George Abbot School is a secondary education school which provides education for 2000 people aged 11 to 18. The school had a history of leaks in the DT rooms above which a profiled sheet metal roof was installed.Following many attempted repairs, Bauder was commissioned to carry out a roof survey on the 228m² profiled sheet metal roof. The report identified issues with not only the gutter area, which was originally believed to be the problematic area, but also with the adjoining profiled roof and also with the large rooflight unit.Bauder Building BoardProject: George Abbott SchoolLocation: Guildford, SurreyRoof Area: 228m²Specifier: Baily GarnerApproved Contractor: Inspire Contract ServicesThe specification Bauder submitted a proposal to refurbish all areas of the failing roof:The gutter area needing standing water to be removed for which Bauder tapered insulation was proposed to create effective drainage falls.The adjoining profiled sheet metal roof requiring a new waterproofing system. The Bauder Profiled Roof Overlay system was determined to be the best solution, using bespoke profiled insulation boards specifically designed to fit the shape of the roof. The Thermofol U15 Fleece Back membrane was then specified as the waterproofing layer providing a robust yet lightweight waterproofing system to the roof.The existing rooflight unit, being one of the problematic areas of the rooftop, was also replaced with Bauder Euroglaze rooflights. Products appliedInsulation infill systemIntended for refurbishing profiled sheet metal roofs or increasing the thermal performance of existing insulated cladding systems.Bauder Euroglaze rooflightsModular rooflight designed to provide high standards of illumination, insulation and ventilation to the interior of flat roofed buildings.

Barony CampusBauder Thermofol PVC single ply waterproofing system withBauderSOLAR FSynopsisBarony Campus is a new build project situated in Cumnock, Scotland. The campus will incorporate a range of primary schools, learning centres and academies within the area, and is the biggest capital project undertaken by East Ayrshire Council.Bauder Building BoardProject:Barony CampusLocation:Cumnock, ScotlandProject type:New buildRoof size:5,230m²Client:Sheppard RobsonMain contractor:Morrison ConstructionApproved contractors:EJ ParkerW.G. Walker & Co                             Q9 Cladding SolutionsThe specificationThe client required flat roof waterproofing as well as a sustainable energy source in the form of solar PV panels. Due to Part L regulations there was a requirement for a large PV array. Main contractors, Morrison Construction, bought into the risk-averse, zero-ballast, zero-penetration solution that the BauderSOLAR system offers. As Morrison Construction had not yet used this system, Bauder conducted a technical seminar to share the benefits of using BauderSOLAR in conjunction with a Bauder single ply membrane and to discuss the acoustic considerations for a building of this nature.The technical support and advantages of a single-source supplier resulted in a specification of a 176.80kWp BauderSOLAR PV system generating an estimated 157,800kWh per annum. The system proposed by Bauder ensured the solution was compliant in relation to the SAP calculations that had been carried out.Products appliedBauder THERMOFOL PVCThis single ply membrane is lightweight and has a high-grade virgin polymer formulation. The PVC formulation ensures it is resistant to chemicals and micro-organism attack making it well suited to receive a green roof.BauderPIR M 60This PIR insulation has aluminium foil facing on both sides and rebated edges to remove a thermal bridge. The matt black facing on both sides enables the board to be installed either way up. BauderSOLAR FThe lightweight, integrated system ensures that the integrity of the roof is upheld throughout the installation of the PV array. The panels are designed to create a 12º angle with modules delivering up to 455w per panel.Project challengesThe client had limited space for the storage of 544 solar panels and they could not be stored on the single ply roof. To overcome this, deliveries of the panels were coordinated with the roofing contractors finishing sections so that the panels could be raised, installed and welded as they arrived to site, mitigating the need for storage. Due to the reduced labour time of BauderSOLAR compared to ballasted systems, the site team managed to install the system quickly and efficiently, making back time lost due to weather delays and enabling the deadline to be met.The BauderSOLAR system is the lightest system on the market at 11.5kg/sqm. The system is also warrantied in combination with the roof membrane to ensure peace of mind is given to the client if any leaks or damage were to occur.System installedBauder Thermofol PVC single ply system1 Bauder THERMOFOL U15 FR1.5mm polyvinyl chloride membrane (PVC) reinforced with a pre-coated polyester cross-weaved matting for mechanically fixed installations. 2 BauderPIR M 60This efficient tissue-faced flatboard insulation has been specially developed for use within Bauder single ply systems. 3 BauderSYN DB-PE 100A blue, polyethylene air and vapour control layer.

However, we found some challenges getting started due to the bad weather but once we finally began it was very straight-forward and fast to install. The technical help received from Chris and the team from design through to project completion was second to none.” 

The project was to convert a former vehicle maintenance and repair workshop into a dwelling. Ground tests did not reveal any significant level of Volatile organic compounds (VOC’s) in the soil but the local authority required a gas membrane to be installed and independently verified.

Products: Flexi heavy – Modular Frameworks & Flexi Access – Bespoke access platforms. Services: Air-handling units & associated access requirements. Roof build-up: Warm roof design – PIR/PUR insulation with PVC/TPO field membrane. Pump House were proud to have been chosen as the preferred supplier of building services support systems to the project, with support frames required to fourteen rooftop air-handling units. Each framework was also accompanied by a bespoke access platform to one longitudinal side of the air-handling units for maintenance purposes.

The Metro Centre is over 22 years old and the building had been experiencing leaks, a problem which was exacerbated by the numerous changes in plant installations on the roof. The original felt waterproofing had reached the end of its working life and a system was required that would keep the building watertight, help comply with current building regulations, and bring the insulation standards up to Part L. A Cold Bonded Built-Up Roofing System was specified for the project consisting of 40mm Decotherm insulation, a Carrier Membrane, and a seamless Decothane Gamma 20 waterproof ‘cap sheet’.
