Waterproof and breathable membrane is a kind of building material that can realize both waterproof and breathable at the same time, which is mainly used in waterproof engineering such as building roof, wall and basement. Its main component is a polymer composite material, the surface is coated with a special waterproof coating, with waterproof, breathable dual functions. Polymer waterproof permeable film is made of polypropylene non-woven fabric and polyethylene film spunbonded. Waterproof breathable film is mainly composed of three layers: PP spunbonded non-woven fabric, PE polymer breathable film, PP spunbonded non-woven fabric. The role of spunbonded non-woven fabric is mainly to enhance the tension and hydrostatic pressure and protect the middle layer (breathable film), the real breathable is mainly by the middle layer PE polymer breathable film. Waterproof polymer film is defined as a thin film laid on the outside of the insulation layer of a building. Building waterproof breathable polymer film is a film laid on the outside of the building insulation layer, it is by strengthening the air tightness and water tightness of the building to save energy consumption, protect the living environment, thereby improving the durability and comfort of the building. The product has good water resistance, air permeability and aging resistance, and the product has a unique respiratory function, can allow water vapor to pass freely, but can not penetrate after condensation into water, so as to ensure that the interior of the building is dry and comfortable, while avoiding condensation and dew damage to the maintenance structure of the building (roof and wall). The structure of the high vapor permeation waterproof vapor permeation film is similar to the structure of the low vapor permeation waterproof vapor permeation film, but because of the change of the material of the polyethylene film, it has good permeability. The throughput can be controlled between 1020g/m2/24h and 2380g/m2/24h. High permeability, so that the water in the building as soon as possible to evaporate, while ensuring the indoor dry and comfortable, it also relatively increased the service life of the building, more suitable for the south and east of the wet construction environment

Waterproof breathable membrane features:

(1) Derflex waterproof breathable membrane is laid outside the thermal insulation layer to wrap the entire building, thereby reducing air leakage and convective heat loss, effectively enhancing the air tightness of the building, simple construction, direct tiling method, and can be fixed with thermal insulation nails.

(2) Derflex waterproof breathable membrane excellent waterproof performance, tight coverage, protect the building from moisture and rain corrosion. Effectively ensure the thermal insulation effect and durability of the building, so that the building is more energy saving and environmental protection.

(3) Install Derflex waterproof breathable membrane outside the insulation layer to ensure that water enters the shell structure. Effectively discharge steam, reduce the risk of condensation on the roof, solve the problem of condensation and moisture, and protect the insulation layer.

(4) Lay Derflex waterproof breathable membrane on the water strip, the needle eye is at the highest point, the rain water falls along the water column, free discharge, waterproof is more guaranteed.

(5) Derflex waterproof breathable membrane protects the insulation layer without mixing fine stone on the insulation layer. Concrete or coated with waterproof material, can reduce engineering costs, ensure quality, long service life.

Application of waterproof breathable membrane:

(1) It is suitable for waterproof engineering of roof and wall of high-rise building.

(2) Suitable for wet and rainy places such as basements and underground pipelines.

(3) Suitable for moisture protection of agricultural greenhouses, industrial workshops and other places.

5、The comparison of waterproof breathable film and coated waterproof, waterproof coil:

1. Compared with coating waterproof, waterproof breathable film has better waterproof effect, better breathable performance and longer service life.

2. Compared with the waterproof coil, the waterproof breathable film has better breathable performance, which can avoid the problems such as humidity and mold breeding in the basement.

3. The price of waterproof breathable film is moderate, which is more economical than coated waterproof and waterproof coil.
