Waterproof breathable membrane

Waterproof breathable membrane for construction is a kind of film laid on the outside of the building insulation layer. It is by strengthening the airtightness and watertightness of buildings to save energy consumption and protect human settlements. Waterproof breathable membrane is made of spunbonded polypropylene non-woven fabric and polyethylene film. The product has good water resistance, air permeability and aging resistance, and also has a unique breathing function, which allows water vapor to pass through freely, but cannot penetrate after condensing into water, so as to ensure that the interior of the building is dry and comfortable, while avoiding water and dew condensation damage The maintenance structure of the building, suitable for roofs and walls.

 Higher moisture permeability is more suitable for the humid construction environment in the south and east, so that the water in the building can evaporate as soon as possible, thereby ensuring a dry and comfortable building indoors, and relatively increasing the service life of the building. Waterproof Roofing Membrane is mainly used in: wooden house structure, steel structure, metal structure, other villa roofs, etc.

Parameter

Material: PE, TPO, PVC

Air permeability: 2000g/m2/24h

Color: white, blue, khaki, gray, black

Feature

1. Good air tightness; the waterproof and breathable membrane is laid outside the insulation layer to wrap the whole building, thereby reducing air leakage and convective heat loss, effectively enhancing the air tightness of the building, simple construction, directly using the tile method, and can be used Insulation nails are fixed.
2. Good water resistance; the excellent waterproof performance of the waterproof and breathable membrane, tightly covered, protects the building from the corrosion of moisture and rain. Effectively guarantee the waterproof and breathable membrane of the building, and ensure the inflow of water into the shell structure. Effective exhaust, reduce the risk of condensation on the roof, solve the problem of condensation and moisture, and protect the insulation layer.
3. Convenient drainage; lay a waterproof and breathable membrane on the water strip, with the pinhole at the highest point, use rainwater to fall smoothly along the water strip, drain freely, and ensure waterproofing.
4. Durable and long life; waterproof and breathable membrane protects the insulation layer, no need to mix fine stones on the insulation layer. Concrete or coating waterproof material can reduce engineering cost, ensure quality and have long service life.
