Product Description

Waterproof breathable membranes are produced by the middle layer polyolefin microporous membrane and two layers of non-woven fabrics. The Microporous Membrane is laid on the roof of the building or the thermal insulation layer of the outer wall, and under the water strip to strengthen the airtightness of the building. At the same time of water tightness, with its unique ventilation function, the moisture in the enclosure is smoothly discharged, thereby effectively maintaining the service life of the building, and playing the functions of thermal insulation, energy saving and improving the living environment.

 

The breathable principle of waterproof breathable fabric can be divided into two types: micropores and hydrophilic group. DERFLEX fabric waterproof breathable membranes use the former. Because there is a huge difference between the minimum diameter of water droplets and the diameter of water vapor, water vapor can be adopted by the principle of diffusion The microporous membrane, liquid water or water droplets cannot pass water molecules due to the surface tension, which prevents the penetration of water and makes the breathable membrane waterproof.
