Wind barrier for walls and roofs
.jpg)
Wind insulation films protect the heat insulation from heat loss due to wind (blowing out). They should have high water vapor permeability providing easy escape of moisture from within the roof or wall constructions.
Material should be laid close to the heat insulation. Leave 10-15 cm overlaps. In order to increase the efficiency of heat insulation, overlaps should be taped using frost and moisture resistant adhesive tapes (for example, Tyvek Tape). Leave a ventilation gap above the film.
