PRODUCT PROFILES | INSULATION AND ACOUSTICS Roofing company breathes easy Experimentarium in Tuborg, near Copenhagen, is described as ‘one of the most exciting buildings to open in recent months’. Designed by Cebra architects, this science centre provides families, school children and science-lovers with high quality science exhibitions where they can ‘touch, play and experience science in a new way’. The use of hard surfaces throughout, coupled with the noise of thousands of daily visitors, meant the architects had to pay special attention to the acoustics. The solution was to install Troldtekt ceiling panels, which are said to provide a sound absorbing surface which contrasts dramatically with the copper, aluminium and glass elements, as well as complementing the interior atmosphere. In addition, because the ceiling is suspended, it can be removed or adapted to accommodate exhibition changes within the 11,500m2 of public spaces. Extended above the original red brick walls of the old brewery, the Experimentarium comprises several new floors, clad in perforated aluminium, enclosing spaces and atriums accessed by curved helixshaped 36 BUILDING PRODUCTS | MARCH 2018 stairways. It is reportedly designed like a theatre with large areas backstage housing staff facilities, workshops, ‘creative rooms’ and offices. The benefits of 100% Troldtekt natural wood panels are said to include high sound absorption, high durability, natural breathability, low-cost lifecycle performance and sustainability as documented by ‘cradle to cradle’ certification at silver level. They are reportedly specified to improve acoustics in many different projects such as schools, leisure centres, pools, commercial, private and public buildings. Available in various sizes and in four grades from extreme fine to coarse, they can be left untreated or painted in virtually any RAL colour. www.troldtekt.co.uk R. G. Leverett, a family-run roofing business, has switched to using BreatherQuilt from YBS, reportedly finding it more costeffective to install, while offering superior performance compared to rival products on the market. R. G. Leverett says it first trialled YBS BreatherQuilt on a 1950s bungalow in Norwich. The original concrete roof tiles were reportedly leaking in several places and offering poor thermal performance. Having fully scaffolded the single storey property and carried out risk assessments, including checking for the presence of asbestos, the firm’s operatives stripped off the tiles, across the main pitch and wing. BreatherQuilt was then used. Business owner, Rob Leverett, said: “We carry out a lot of work like this for the owners of older properties and decided to try YBS BreatherQuilt because not only is it cheaper than the other products we were using, but it offers a better insulation value as well.” Rob continued: “It is straightforward to install and we had absolutely no problems with it. I am sure we will be purchasing BreatherQuilt for more projects in the future.” www.ybsinsulation.com Driving success at golf club Kingspan has installed its Optim-R balcony and terrace system at the Centurion Golf Club in Hemel Hempstead. A recessed roof terrace was incorporated into the building design to take advantage of the views across the lake and 18th green, extending the member bar seating area. To ensure a level threshold for a smooth transition from inside to outside, while also keeping the area well insulated, the Kingspan Optim-R balcony and terrace system was specified. The insulation features vacuum insulation panels (VIPs) with a microporous core which is evacuated, encased and sealed in a thin, gas-tight envelope. With a declared thermal conductivity of 0.007 W/m.K, Kingspan Optim-R VIPs can reportedly deliver an insulating performance up to five times better than that of commonly available insulation materials. The 20 mm Kingspan Optim-R balcony and terrace system was installed on the terrace below Kingspan Thermataper TT47 LPC/FM. The use of this product is said to have eliminated the need to incorporate a structural fall into the design, and provided a lightweight and dry alternative to screeding. www.sgpr.co.uk Absorbing the sounds of science with natural wood panels
