Roofing Updates SOUND AND DRAINAGE PROTECTION CMS Danskin Acoustics has a new sound reducing underlayment product specially developed for external surfaces, such as on rooftops, terraces and balconies, which also provides rainwater drainage and membrane protection. ‘REGUPOL sound and drain 22’, exclusively available from CMS Danskin Acoustics in the UK, is a polyurethane elastomer composite with a dimpled profile on the underside to facilitate drainage and a geotextile-laminated top to prevent dirt penetration. It provides impact sound insulation with effective acoustic results in a range of different structures. CMS Danskin Acoustics’ Ian Bull said: “Sound insulation on roof terraces is just as important as indoor sound insulation because structure-borne sound from footfall or services plant, such as rooftop air conditioning units and heat pumps, is transmitted from the external surface to the building interior. However, most sound impact materials are unsuitable for outside applications; REGUPOL sound and drain has been developed for outdoor use.” ‘REGUPOL sound and drain 22’ provides highimpact sound insulation levels of 28 to 37dB depending on the specific build-up, is rot-proof, largely resistant to ageing, gives good drainage and water flow capacity and functions as a protective layer. Acoustic test data is available for six floor assemblies, including varying thicknesses of concrete tiles, wooden decking boards and ceramic tiles, as well as test data confirming compressibility, fire, thermal and moisture behaviour and resistance to ageing. Made from recyclate, ‘REGUPOL sound and drain 22’ is 15mm thick and has a load bearing capacity up to 50 kN/m². Projects to date include The Marienturm in Frankfurt am Main, a 38- storey building primarily occupied by offices, and 36-38 Berkeley Square, a new office and retail development in London’s Mayfair. ‘REGUPOL sound and drain 22’ is a Bronze level Cradle to Cradle Certified product. Cradle to Cradle is a multi-attribute standard for designing and making products that enable a healthy, equitable and sustainable future. Cradle to Cradle Certified is a registered trademark of the Cradle to Cradle Products Innovation Institute. Distributed in the UK by CMS Danskin Acoustics, REGUPOL products are specified worldwide for their noise and vibration reduction properties. www.cmsdanskin.co.uk WHITESALES NAVIGATES HERITAGE CHALLENGES Whitesales has replaced the original timber rooflights in the Grade II* listed Birmingham Museum & Art Gallery with new bespoke aluminium rooflights, ready for the reopening of the museum during <strong>2024</strong>. Built in 1885, the Birmingham Museum & Art Gallery has long housed treasures from the likes of Edward Burne- Jones, William Morris and Dante Gabriel Rossetti, and has an unrivalled 2,000 piece Pre-Raphaelite collection. However, it closed in November 2022 for essential maintenance which has included electrical work, upgrading of the heating, lift replacement and roof repairs. The new rooflights were a key element in the roof repairs, so the challenge for Whitesales was to supply and install high performance, energy efficient replacements for the timber originals, which satisfied the constraints of the Grade II* listing and met the requirements of the City Council’s conservation office. The solution they developed included one bespoke Whitesales Monopitch 2610mm x 1260mm rooflight with vertical front face and sides set at 350mm, and two bespoke lantern rooflights with sides set at 440mm and 450mm, all finished in an anthracite grey on the exterior and white on the interior, and all CWCT TN92 Class 2 non-fragile to ensure the safety of anyone walking on the roof. Whitesales worked closely with contractors ISG throughout the design and specification process. They visited the site for a survey, attended design meetings and delivered a sample to the site so that everyone on the client team was happy with what was being supplied in terms of both performance and aesthetics. They also ensured that the rooflights were all fabricated and safely delivered to site in manageable-sized elements to take into account the fact that access in and around the city centre site was difficult. Whitesales has a long standing relationship with ISG, based on the quality of the work carried out on previous projects. For ISG’s Trainee Construction Manager Ryan Linnecor, Whitesales impressed with their knowledge and experience on heritage schemes. He commented: “Whitesales had a clear understanding of the Grade II* listed scheme and the constraints that presented. They impressed us once again with their approach on how to undertake the work sympathetically and the finished installation is of a very high quality.” www.whitesales.co.uk 30 TC FEBRUARY <strong>2024</strong>
