Polymer ethylene Waterproof breathable film, composed of three layers of PP, PE and PP, is a new type of waterproof green building material, widely used in China, and also exported to Europe, South America, Russia and other regions and countries, with thickness of 0.3mm, 0.49mm and 0.65mm, and different prices, curtain Of wall Ah, the slope surface has been applied, and the effect is well recognized by the majority of users. The manufacturer supplies directly, which guarantees both the quality and the price. You can buy happily and use with confidence.
The Kedebang waterproof and vapor permeable membrane is made of high-performance materials, which can allow water and gas to pass freely, but it can not be penetrated after being condensed into water. This ensures that the building is dry and comfortable, and avoids the condensation of water to damage the roof and wall of the building, as well as damage to indoor items. The working principle of Kedebang waterproof and vapor permeable membrane can be simply described in the figure on the left: let's first analyze the cause of condensation. The air contains colorless moisture, which is usually measured by humidity (RH%). The higher the air temperature is, the more moisture it contains. When the temperature decreases, the air cannot contain the original moisture. The lower the air temperature is, the higher the humidity will be. When the humidity reaches a high standard, the moisture will condense into liquid, and condensation will occur. This temperature is called condensation point in the building, As long as the volatilization of hot air inside the building contacts the roof and wall with lower temperature, condensation will occur. The temperature at this time is called the condensation point in the building. As long as the volatilization of hot air inside the building contacts the roof and wall with lower temperature, condensation will occur. When condensation occurs, water droplets will form on the roof or wall surface, The water drops are absorbed by the building, thus damaging the wall and roof structure, or dropping, damaging the items in the building. The special waterproof and vapor permeability of the Kedebang waterproof and vapor permeable membrane can not only serve as a waterproof layer, but also solve the moisture-proof problem of the insulation layer. On the one hand, water vapor can pass through and will not accumulate in the insulation layer; On the other hand, dew condensation or water seepage on the roof or wall will be effectively isolated from the thermal insulation material by the waterproof and vapor permeable membrane of the state of Kodak, instead of entering the thermal insulation layer, so as to form an integrated protection for the thermal insulation layer, ensure the effectiveness of the thermal insulation layer, and achieve the role of continuous energy conservation.
