Membranes & barriers
Description
A roofing underlay in polyester non-woven paired with a monolithic TPU-copolymer coating, permeable to water vapour, watertight and non-slip. The integrated SK adhesive strips along the edges allow a glue-on-glue bond at the transverse overlap, with no added tape. Certified resistant to driving rain by TU Berlin, it makes it possible to build a roof secured against driving rain in ZVDH class 2 with no added sealing strips under the counter batten. Its field of use covers lowland climates up to 900 metres of altitude, on a continuous or discontinuous deck, in contact with the insulation or not. Thanks to its nail-tight coating and its resistance up to 100 °C, it accepts the laying of nailed slates directly on top, of stone slabs or of bitumen shingles. Low pitch is admitted from 10°, and down to 5° only where the nail seal under the counter batten is reinforced. It complies with NF EN 13859-1 and 13859-2 and with annex A of the NF DTU 40.29.
