Waterproof and vapor permeable membrane is a new type of polymer vapor permeable and waterproof material, which is suitable for curtain wall, profiled steel plate, exterior wall of rigid wood structure and sloping roof. In terms of manufacturing technology, the technical requirements of waterproof and vapor permeable membrane are much higher than that of general waterproof materials; at the same time, in terms of quality, waterproof and vapor permeable membrane also has functional characteristics that other waterproof materials do not have. While strengthening the air tightness and water tightness of the building, the water-proof and vapor permeable membrane has its unique vapor permeability, which can make the water vapor in the structure quickly discharged, avoid the mould in the structure, protect the property value, and perfectly solve the problems of moisture-proof and human health; the water vapor quickly discharged, protect and maintain the thermal performance of the structure, which is a new energy-saving material of health and environmental protection.
Working principle: the general water-proof and vapor permeable membrane uses the vapor permeable membrane through the microporous principle. During the construction process, it is easy to wear and block the micropores, resulting in the failure of vapor permeability, or the micropores become larger, resulting in material leakage, so that the material loses its own vapor permeability and water-proof function. LB series waterproof and vapor permeable membrane adds hydrophilic base in the polymer vapor permeable membrane. Through the hydrophilic characteristics of hydrophilic group, water drops can not penetrate and water vapor can freely penetrate, ensuring the stability of the product's vapor permeable and waterproof performance and the durability of its service life.
Main benefits of waterproof and breathable membrane:
1. While strengthening the water tightness of the building, the waterproof and vapor permeable membrane can rapidly discharge the structural water vapor, protect the thermal performance of the enclosure structure, avoid the breeding of roof mould, and improve the air quality of the room.
2. The waterproof and vapor permeable membrane is laid on the insulation layer and the water strip. The waterproof and vapor permeable membrane between the two water strips sags naturally, and the nail hole is at the high point. The rainwater is not easy to enter, so the waterproof is more guaranteed.
3. Waterproof and vapor permeable membrane is used to protect the thermal insulation layer. No need to make fine aggregate concrete above the thermal insulation layer, which can reduce the cost of the roof.
