How to avoid condensation on Vents

With its unique microporous structure, Vents has excellent water vapor transmission and waterproof performance in the building envelope, and has good market development potential. Next, let’s analyze the function mechanism of Vents to deal with the problem of building condensation, and put forward the key to the performance control of Vents from the perspective of experimental testing and production technology.

The operating principle of Vents can be divided into two types: microporous and hydrophilic groups. Vents uses the former, because the minimum diameter of water droplets is about 20 microns, while the diameter of water vapor molecules is only about 0.0004 microns. There is a huge difference between the two diameters. The difference is that water vapor can pass through the microporous membrane through the principle of dispersion, and liquid water or water droplets can not pass through the water molecules due to the effect of surface tension, which also avoids the penetration of water and makes the breathable membrane waterproof.

In fact, the installation method of Vents has greatly affected the waterproofing of the product and the effect of preventing condensation! No matter what water vapor passes through the Vents, it needs to pass through the channel through the barrier layer of the building wall or the building structure. The professional products we produce The breathable and waterproof membrane can scientifically and conveniently allow water vapor to permeate through the past!

When the generated water vapor condenses into water droplets on the building barrier layer, they will drop on the Vents, and the Vents we installed before have a waterproof effect at this time!
