Renolit Alkorplan - Model L -Loose Laid Roofing Membrane

A ballasted or protected roof implies that the roofing membrane is not fixed nor adhered to the roof structure. The membrane is loose-laid and covered with gravel, paving slabs, substrate etc… Obviously, the ballast offers a good protection against wind uplift. It also protects the membrane against direct stress caused by temperature fluctuations, punctures, tears, etc. but also against ageing, as the membrane is not exposed to UV radiation. Thanks to the glass fleece reinforcing, the RENOLIT ALKORPLAN L membrane has an excellent dimensional stability. A simple and fast installation without glue or fasteners and regardless of weather conditions, is undoubtedly an advantage. The seams are hot air welded at the overlap with either manual or automatic welding equipment.
