This week’s news from roofing manufacturers


  • German test house, the Federal Institute for Material Research and Testing, has confirmed that Kalzip standing seam roofing remains fully functional after 40 years’ exposure to weather. It monitored three roof installations for 40 years to document how they corroded. Kalzip said the aluminium product is inherently durable and had its natural performance characteristics enhanced by an additional alloy layer.
  • Kingspan Insulation has produced technical bulletins that detail how to achieve BREEAM credits when using its Kooltherm and Therma range of insulation boards and its TEK building system, which can be used for roofing applications. Kingspan said all its Kooltherm K range and foilfaced Therma products received a BRE Green Guide A+ rating.
  • Rubbeco has signed an exclusive agreement with the Canadian Timber Group to supply its product to waterproof the roofs of Canadian Timber Group’s timber-framed buildings. Rubbeco is spray applied and provides a seamless, flexible membrane with, the company says, a life expectancy of at least 50 years.
  • Roofglaze has launched a website that provides full information on its range of rooflights. These include thermally efficient Nanogel products and its Cool & Clear glazing range. The site also has a technical section with details of building regulations and other legislation affecting rooflight specifiers.
  • Single-ply roofing system specialist, Sika-Trocal, has launched an online tool for the creation of flat roof specifications. There are two versions, the “pro” and the “basic”, with the former capable of providing a specification for three different roof areas on the same building.
