Vapour permeable membrane

Three-layer roof membrane CONTEX is a supplement for wide range of water insulation. Being highly permeating for water vapour, it is applied for covering of roof surface. The membrane CONTEX protects the thermal insulation and roof structure against moisture. The membrane structure allows removal of moisture outside to the ventilating layer and prevents moisture penetration to building interior. All variants of the roof membrane CONTEX consist of three basic layers. The inner layer is an insulating one, and external layers, which are made of polypropylene nonwoven, protect the inner layer and reinforce the membrane. The higher grammage is, the higher is resistance of insulation to mechanical and physical influences. The roof membrane CONTEX may be a cheaper and considerably more effective alternative for full roof structure boarding.
