Membranes & barriers
Description
A reinforced multi-layer coated roofing underlay whose surface gives a nail seal obtained without an extra strip under the counter batten. This makes it possible to weatherproof the roof temporarily with no risk of water ingress at the joints and perforations, in ZVDH class 3; resistance to driving rain is certified by the TU Berlin building physics institute. The reinforced build-up allows laying on rafter centres of up to 1.2 m or between battens beyond 40 cm under DIN 4426, and the non-slip surface limits the risk of falls during installation. The coating brings ultraviolet stability and resistance up to 100 °C, which opens up use under slates, stone slabs, bitumen shingles or a metal roof, on a continuous or discontinuous deck, at low pitch from 5° and in mountain climates between 900 and 2000 metres. Rolls of 75 m², 50 x 1.5 m.
