Isolair is a water-resistant fibreboard for application as underlay in roofs and as a water resistant and wind tight layer in ventilated facades.
Boards are supplied in a standard size of 2500mm x 770mm and in thicknesses of 22mm, 35mm and 60mm.
The edges of the Isolair are endowed with tongue and groove which effects a solid joint that can be placed between rafters/studs. Isolair is applied in over rafter insulations as protection of the insulation material or in inter rafter constructions directly on the beams instead of underlays.
