Vapour permeable underlays for discontinuous roofings (according to: EN 13859-1)

FIELD OF APPLICATION: Used as a subsidiary protective layer against moisture (liquid water penetration, wind-blown snow) and wind in pitched roof structures. These products are laid directly over the thermal insulation, timber boarding or other solid support, paralell to the eaves with minimum 10 –15 cm overlapping and the printed or coated side to the roofing. The underlay is fixed along the rafters with proper counter battens (min. 50/50 mm). These battens lift the tiling battens off the underlay, create an effective drainage path to the eaves and a ventilation gap between the eaves and the ridge. Sealing of the overlaps with MASTERMAX TAPE encreases the wind-tightness.
