The thickness of the enhanced waterproof vapor permeable membrane is more than 0.49mm, relative to the wall Type I Waterproof vapor permeable membrane, with better tensile strength and tear strength. Thickened polypropylene can play a good moisture-proof, wear-resistant, windproof, dust-proof effect, especially suitable for sloping roof structure. Compliance with standards JC/T2291-2014 Type parameter.
Ordinary steel structure roof or curtain The waterproof and vapor permeable film thickness of the system is 0.5mm and a little more than 0.3mm, and the product performance is fully adequate. What is the significance of developing and producing enhanced waterproof and vapor permeable membrane? The waterproof and vapor permeable membrane of ordinary metal roof is paved on the flat insulation layer structure in a large area, so workers trample less during construction, while the wall system is suspended, and the membrane body is not stressed. However, when paving waterproof and vapor permeable membrane on the roof of some villas and wooden structures, workers often need to kneel on the waterproof and vapor permeable membrane or pedal on the waterproof and vapor permeable membrane, and the roof is of slope type, so the waterproof and vapor permeable membrane needs to have higher tensile strength and tear strength. The reinforced waterproof and vapor permeable membrane has better mechanical strength than the ordinary waterproof and vapor permeable membrane, and is mainly used in the pitched roof structure of villas, while the waterproof performance and air permeability are not affected.
The main benefits of applying waterproof and vapor permeable membrane to sloping roofs are as follows:
1. The waterproof and vapor permeable membrane on the pitched roof strengthens the water tightness of the building, at the same time, allows the structural water vapor to be discharged rapidly, protects the thermal performance of the enclosure structure, avoids the breeding of roof mold, and improves the indoor air quality.
2. The waterproof and vapor permeable membrane of the pitched roof is laid on the insulation layer and the waterspout strip. The waterproof and vapor permeable membrane between the two waterspout strips naturally droops. The nail hole is at the highest point, so the rainwater is not easy to enter, and the waterproof is more guaranteed.
3. The waterproof and vapor permeable membrane on the pitched roof protects the insulation layer. No fine aggregate concrete is needed above the insulation layer, which can reduce the roof cost.
Nantong Kangda Composite Material Co., Ltd & Jiangsu Kedebao Building Energy Saving Technology Co., Ltd. is an old brand enterprise engaged in the production and export of waterproof and vapor permeable membranes in China. We help many waterproof material companies in Europe and the United States contract to produce waterproof and vapor permeable membranes all year round. Our Kedebang brand waterproof and vapor permeable membrane is produced with the same material, same line and same standard as the export products, and will not be in the same quality as some manufacturers pin Two sets of quality standards are exported. Our domestic "Kedebang" waterproof and vapor permeable membrane is widely used in various high-speed railway booths, aircraft terminals, large industrial plants, storage warehouses, sports exhibition centers and other projects, with market share reaching 30% 。 Welcome domestic and foreign customers to visit our company for consultation.
