Definition and working principle of Breathable membrance

Breathable membrance by hot pressing composite multilayer high performance material, kangda is nantong kangda composite materials co., LTD., brand, Breathable membrance can make water vapor through freely, but into the condensate water cannot penetrate, thus ensuring building insulation and dry and comfortable, at the same time, avoid condensation water damage the structure of the roof and wall, further damage to the indoor items, reduce building energy consumption.

The working principle of kangda Breathable membrance

1. Let's first analyze the cause of condensation. The air contains colorless water vapor, which is usually measured by humidity (RH%). The warmer the air, the more water vapor it contains,

When the temperature falls, the air can't contain the original water, the lower the air temperature, moisture increases, when the moisture of 100%, water vapor condenses into liquid, dewing phenomenon occurs, then called the dew point temperature in the building, as long as the building of the hot air volatilization in contact with the lower roof and wall temperature, condensation phenomenon occurs, then called the dew point temperature in the building, as long as the building of hot air volatilization exposed to low temperature of the roof and walls.

2, condensation phenomenon will occur, water vapor will be formed on the roof or wall surface water droplets, water droplets are absorbed by the building, thereby destroying the wall and roof structure, or dripping, damage the building items.

3, kangda breathable membrance has the function of waterproof vapor permeable, in addition to the role of the waterproof layer, protect the insulation layer, can also solve the insulation layer of moisture (also known as the problem of moisture vapor). On the one hand, it allows water vapor to pass through, preventing water vapor from gathering inside the insulation layer to form water droplets. On the other hand, dew or water seepage on the roof or wall will be effectively isolated from the thermal insulation material by the waterproof breathable film, and will not let water droplets enter the thermal insulation layer, thus forming a comprehensive protection of the thermal insulation layer, ensuring the efficiency of the thermal insulation layer, to achieve the role of continuous energy saving.

4, kangda breathable membrance has the function of vapor permeation, and can prevent water infiltration. Protect the integrity of the building.
