Technical requirements for waterproof breathable membrane

Waterproof breathable membrane is a new type of polymer waterproof material. In terms of production process, the technical requirements of waterproof breathable membrane are much higher than that of general waterproof materials.

There are obvious pressure points on both sides of the waterproof and breathable membrane. That is because the production process is compounded by hot pressing. Please note that it is not the dot pattern of the non-woven fabric itself, but the obvious overlapping dot pattern.

At the same time, the waterproof breathable membrane also has its development history, and it has also developed step by step into the current waterproof breathable membrane.

Waterproof and breathable (moisture-permeable) material: also known as breathable material (breathable fabric, breathable paper, etc.), a material that can prevent the passage or penetration of liquid water, and at the same time can permeate gas (or water vapor).

The waterproof breathable membrane can be waterproof, dustproof, oil-proof, chemical-resistant, high-low temperature resistance, anti-aging, etc., to improve the reliability of the product in complex use environments.

The waterproof and air-proof membrane is very good for waterproofing, but the water vapor in the building structure cannot be volatilized, and the metal roof will definitely rust in the long run.

After choosing a good waterproof and breathable membrane, it is necessary to start the construction of waterproof and breathable membrane. In the construction process, try to avoid penetration and opening on the waterproof and breathable membrane, and try to ensure the integrity of the waterproof and breathable membrane. If open or penetrated, seal the penetration and opening with butyl tape.
