What are the quality requirements for using eptfe waterproof breathable membrane?

That is, 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 the needs of users, and the whole should be kept uniform and straight, and the occlusion should be kept compact at the corners. and consistency, ensuring that the breathable membrane is precisely sized and the cuts are neat.

Secondly, the base layer of eptfe waterproof and breathable membrane is treated. Its vertical flatness range should be controlled within 5 mm, so as to ensure its compact structure, and all tools and facilities should be ensured before fixing and installation. The design drawings are installed in a standardized way, so as to ensure the safety and standardization of the working environment of the eptfe waterproof and breathable membrane, 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 to meet the requirements, it cannot be exposed to harsh environments for a long time, because whether it is high temperature or low temperature, as well as rain and snow weather and strong wind, etc. It has a very adverse effect on the rock wool board, and although the eptfe waterproof and breathable membrane can effectively reduce this adverse effect, long-term exposure will also reduce the life of the breathable membrane. The waterproof and breathable membrane manufacturer tells you that when installing the eptfe waterproof and breathable membrane, you should also ensure that the installation surface is flat and complete, and there should be no gaps and wrinkles, otherwise there will be leakage.
