PRODUCT PROFILES | ROOFING, CLADDING AND ACCESSORIES Delivering rustic charm for historic barn conversion 54 BUILDING PRODUCTS | DECEMBER 2017 Fire retardant membrane developed for cladding Renowned for providing high quality membrane options for controlling the heat, air, moisture movement in buildings (HAMM), A. Proctor Group has developed Fireshield, a new vapour permeable membrane, which is designed specifically to improve the fire protection behind cladding. Fireshield is the culmination of research to produce a vapour permeable membrane with a fire proof surface, which has a unique composition that actively reacts to prevent fire taking hold. The coating of Fireshield is designed to actively extinguishes fire rather than just resist it, and significantly reduce the formation of droplets and smoke. Fireshield is classified as Class B, s1–d0 according to��the Euroclass system, which classifies the fire performance of building products. The performance of Fireshield is reportedly in advance of the requirements of the current classification grading. Fireshield is said to complies with BS5250, BS4016 and NHBC requirements for vapour permeable walling underlays. It��is installed and fixed to the substrate in the same manner��as standard breather membranes using mechanical fixings. www.proctorgroup.com Making time-saving a matter of course Providing both swift installation and a realistic slate-effect, next generation SlateSkin is the latest enhancement Eurocell has developed for Equinox, its tiled conservatory roof system. Together, SlateSkin and Equinox are said to create the most advanced system currently available. Now with ‘multi-course’ tiles built in to each sheet, the SlateSkin GRP system reportedly reduces the time spent positioning and nailing tiles, with no compromise on build quality or aesthetics, while its lightweight construction allows the roof pitch to be set anywhere from just 5deg. to 35dº.SlateSkin is also the only tile system tested down to a 5º pitch. Guaranteed for 25 years, the SlateSkin sheet-tiling system is not only durable but also considerably faster to fit than other conservatory tile roofing methods. When combined with the Equinox system, it reportedly meets the requirements of BS 476 Part 3:2004 for the External Fire Performance of Roofs, the classification for fire penetration. Equinox kits are said to offer a ‘one box solution’ – with SlateSkin sheets pre-cut to size and numbered for easy identification and installation. Plus, all the sealants and fixings required to install the roof are also in the box. www.eurocell.co.uk/slateskin Scottish school sets tough test for slate refurbishment Lochwinnoch Primary School has provided a showcase for Cambrian Slate from Redland, demonstrating how an early 1900s traditional building can still retain its original appearance using a modern slate substitute, along with traditional slate detailing. The roof of the 111-year-old school was originally slated using Scotch slate that was at the end of its lifespan so rain penetration was causing a major issue. Redland carried out a full Redland SpecMaster roof specification together with James Grant, examining every aspect of the roof in detail. These included raking valley details, sprocketed eaves, changes of pitch on the roof slope, detailing of top edge and side abutments, flat to pitch lead, ventilation at eaves and ridge, and underlay details. All work was carried out in compliance with BS 5534: 2014 Code of Practice for Slating and Tiling and BS 5250 Code of Practice for the Control of Condensation in Buildings, ensuring that high and low-level ventilation was provided along with two mechanical fixings for each tile. www.redland.co.uk Lincoln interlocking pantiles from Marley Eternit have been used for a double barn conversion project in the Teversal conservation area. The tiles were chosen as an easyto fix way of achieving the traditional pantile aesthetic required by local planning. Adrian Smith Builders was appointed to complete a full roof refurbishment on both of the barns. Set in a conservation area, with many listed buildings dating back as far as the 12th century, traditional red clay pantiles are an important part of the local vernacular in Teversal and are often dictated by planning. With a roof structure that was far from flat, Adrian Smith recommended a new type of pantile that would be easier to install, but still give the traditional curved rustic aesthetic dictated by planning. The Lincoln tile is available in Rustic Red and Natural Red with a comprehensive range of fittings. Compatible with Marley Eternit’s Universal Dry Fix systems and Mortar Hip and Ridge fixing kits, the pantiles can also be installed with the manufacturer’s one-piece tile clip, SoloFix, which can save up to 30% roof clipping time compared to traditional clip fixing. www.marleyeternit.co.uk/lincoln
