The role of the waterproof breathable membrane is to protect the external insulation layer of the building.
First, the waterproof breathable membrane is waterproof, which can prevent the external water from entering the maintenance structure of the building, so that the maintenance structure will appear moldy, degummed, and fall off, which protects the user’s life safety.
Second, it is breathable, and the unique microporous structure of the waterproof and breathable membrane makes it breathable.
Moisture will inevitably enter the building envelope during use. Even if the sealing is particularly good, moisture will form in the envelope due to condensation. If the water is not discharged in time,
It will affect the normal use of the building’s thermal insulation layer, so the waterproof and breathable membrane can well protect the usability of the external thermal insulation layer of the building.
Third, it can be drained. The waterproof breathable membrane and the thermal insulation cotton are fixed with thermal insulation nails. One thermal insulation nail is a risk of water seepage. When a facade is down, there will definitely be places where water seeps. Jinpo waterproof breathable membrane can directly drain water without seepage, which is also the strong competitiveness of our products.
