synthetic roof underlayment made in China

The breathable membrane has the function of waterproof and air permeable. When use this membrane wrap the insulation material, it will not stop the air or moisture get through itself, and when the moisture come condensation, the breathable membrane will keep the water drops on outside surface of the membrane. As the breathable membrane is hydrophobic, the water drop will not stay on the membrane or been absorbent, but will be fall down around the membrane, until the edges of the membrane and get out of house. So the breathable membrane is mainly used for pitched (sloppy) roof or wall wrap.

Breather Membranes are high performance vapour permeable breather membranes for installations within Timber Frame, composite Structural Insulated Panel (SIP) and wall panel system designs.

"KANGDA" breathable membrane thermal laminating from 100% returnable polymer material by the advanced technology, we own independent intellectual property which enable us to be the only company in China who scale produce membrane by this technology.
