What are the quality requirements for using waterproof and breathable membranes?

The overall thickness and width of the eptfe waterproof and breathable membrane should be strictly controlled. The thickness and width of the rock wool board should meet the regulations and user needs, and the entirety should be kept uniform and straight. The corners should be kept compact and Consistency ensures that the breathable membrane is precisely sized and the cuts are neat.

The second step is to treat the base layer of the eptfe waterproof and breathable membrane. Its vertical flatness range should be controlled within 5 mm to ensure its compact structure. Before fixing and installation, it should also be ensured that all tools and facilities are in accordance with The design drawings are installed in a standardized manner, so as to ensure that the working environment of the eptfe waterproof and breathable membrane is safe and standardized, otherwise it will affect the normal use and life of the eptfe waterproof and breathable membrane.

Then there are the requirements for each system part. In addition to the density and design of the rock wool board, it must not be exposed to harsh environments for a long time, because no matter it is high or low temperature, as well as rain, snow, strong winds, etc. It has a very adverse impact on rock wool boards. Although eptfe waterproof and breathable membrane can effectively reduce this adverse effect, long-term exposure will also reduce the life of the breathable membrane.
