KENTEX breathable underlay membranes are produced with 3 layers. A non-woven material consisting PP as top and bottom layer protects the functional membrane in the middle from damage and reduces the slip hazard during application. Micro porous film, between the two layers , is to form a breathable waterproof membrane.

>>>Why Kentex?
