The New Generation of Vapour Permeable Membranes
Weather tightness is the essential property of roofing membranes. This property should be guaranteed not just under laboratory conditions, but particularly under conditions typically found on construction sites where roofing membranes need to provide durable protection against intruding dampness. Micro-porous roofing membranes manufactured using conventional technologies may cause problems when exposed to the real life weather impact on the roof.
The quality of nonporous closed cell membranes is achieved by using an uninterrupted film. The liquid polymer is poured in-between two layers of nonwoven fabric at a temperature of over 200°C bonding these when cooling down.
Water Tightness: Closed cell membranes are robust and perform well in conditions where the surface tension of water is reduced.
The Result: The membrane remains tight, no extra work, no extra cost, satisfied customers.
The vapour is diffused down the molecule chains on the basis of a chemical reaction. This results in a high degree of vapour diffusion with highest weather tightness against driving rain.
