Trending Products Air Vapour Barrier Membrane - Flame-retardant Waterproof And Breathable Membrane – JiBao

The waterproof and breathable membrane is composited with high-performance materials, which can allow moisture to pass through freely, but cannot penetrate anymore after condensing into water. So as to ensure that the building is dry and comfortable, and at the same time to prevent the condensed water from damaging the roof and walls of the building, and damaging indoor objects.

The flame-retardant waterproof and breathable membrane has the characteristics of being extinguished from the fire and has a certain protective effect on safety.

Description of the working principle of waterproof and breathable membrane: Let’s first analyze the cause of condensation. The air contains colorless water vapor, which is usually measured by humidity (RH%). The higher the temperature of the air, the more water vapor it contains. When the temperature decreases, the air cannot contain the original water vapor. The lower the air temperature, the humidity increases. When the humidity reaches 100%, the water vapor condenses into liquid. , Condensation occurs. The temperature at this time is called the condensation point. In the building, as long as the hot air in the building volatilizes and touches the lower temperature roofless and walls, condensation will occur. The temperature at that time is called the condensation point. In the building, as long as the hot air in the building volatilizes and touches the lower temperature roof and walls, condensation will occur. When condensation occurs, it will be on the roof. Or water droplets are formed on the surface of the wall, and the water droplets are absorbed by the building, thereby destroying the wall and roof structure, or dripping and damaging the items in the building, use the unique waterproof and vapor permeability of the waterproof and breathable membrane, in addition to acting as a waterproof layer In addition, it can 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, condensation or water seepage on the roof or wall will be effectively isolated from the insulation material by the waterproof and breathable membrane, and will not enter the insulation layer In order to form a comprehensive protection for the insulation layer, ensure the effectiveness of the insulation layer, and achieve the effect of continuous energy saving.

Waterproof and breathable membrane, also known as polymer anti-adhesive polyethylene waterproof and breathable membrane, is a new type of waterproof and green building material. It is widely used in China. It is also exported to Europe, South America, Russia and other countries in steel structure roofs, railway stations, etc. High-speed railways, curtain walls, and slope surfaces have been widely used, and the effect has been affirmed by the majority of users.
