The water vapor of the air always permeates from the high-temperature side to the low-temperature side. A special air insulation membrane for cold storage is arranged on the high-temperature side of the insulation layer, while Hypak® waterproof & breathable material with strong hydrophobic and breathability is arranged on the low-temperature side, which can not only prevents water vapor from entering the insulation layer but also allow the water infiltrating into the envelope to diffuse.

The water vapor of the air always permeates from the high-temperature side to the low-temperature side. A special air house wrap insulation vapour barrier membrane for cold storage is arranged on the high-temperature side of the rigid insulation vapor barrier layer, while Flashspun Hypak™ waterproof & breathable material wall insulation vapor barrier with strong hydrophobic and breathability is arranged on the low-temperature side, weather smart building wrap can not only prevents water vapor from entering the wall insulation vapor barrier layer but also allow the water infiltrating into the insulation vapour barrier to diffuse.

The internal temperature of the cold storage is generally -30℃~-10℃, which is very different from the outside temperature, so it is easy to form condensation water.

Recently, favorable policies for green buildings in many provinces and cities across the country are being intensively implemented. The development of green buildings is not only the key to our realization of the dual-carbon goals, but also an important link in the global sustainable development trend. To build energy-saving buildings, the requirements for house wrap materials are very high, and environmental protection and high strength are far from enough. Problems such as water vapor and wind protection are the main reasons that affect the thermal insulation performance of buildings and increase building energy consumption.
