Breather membranes are installed in pitched roof and timber frame wall constructions to protect the building envelope against wind driven rain and moisture while allowing water vapour to escape. Our range includes the Powerlon UltraPerm range from ITP — BBA certified for all pitched roof types including warm and cold, supported and unsupported, ventilated and unventilated roofs, and for timber frame wall applications. Available in four grades to suit different exposure zones and performance requirements.
