hypak1 on 28 Apr 23The 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.

hypak1 on 10 Sep 24The 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.
