Adevapor 35 membranes comprise fibreglass matt, non-woven polyester reinforced polymer modified bitumen underlayers, for use as vapour control layers. In addition, a membrane incorporating a fibreglass felt coupled to an aluminium lamina can be utilized as a vapour barrier.

Both sides of the Adevapor 35 membranes are finished with the Textene treatment, a film of textured polymeric fibres. These improve adhesion for the direct bonding of compatible thermal insulator boards by means of a flame gas-torch.
