Fakro XDP Insulating Set
The XDP insulation set is used for quick and tight fitting vapour permeable or vapour barrier insulation around any window. It consists of an air-permeable underfelt collar for connecting the window with roofing membrane used in the roof structure. The collar is made of a premium quality high vapour permeable EUROTOP roofing membrane. Sides of the flashing are made in such a way so that they enable laying the collar directly onto battens, regardless of the spacing between them or their thickness.
