Product Description

waterproof breathable for roof underlayment

Building up principle of 3 layer breathable roof membrane:

3 layer breathable roof membrane, thermal laminated by high polymer material + polyolef in microporous membrane + high polymer material, we create this technology in China which is advanced all over the world. Polyolefin microporous membrane has excellent breathability, as well as good duration. Polyolefin microporous membrane has not only acid and alkali resistance, but also good extensibility which enable the fasresilience after tearing by nail so that to improve the sealing performance.

Operating principle:

There are two kinds of operation principle for breath: microspore and hydrophilic group. Breawarf breathable roof membrane adopt the principle of microspore. The minimum diameter of water drop is about 20 micron while the diameter of water vapour molecule is about 0.0004 micron, because of the enormous difference, water vapour can get across according to the dif fusibility, while water molecule can't pass because of the surface tension. As a result, the breathable membrane can prevent osmotic water , so that to have the water proof function.
