PANZHU WRAP Waterproofing Membrane HP-F49 Enhanced As the building energy conservation and environmental protection requirements are getting higher and higher, a large number of thermal insulation products are produced. PANZHU WRAP Waterproofing Membrane is one of them.PANZHU WRAP Waterproofing Membrane is used to protect the external insulation layer of the building.First of all, the waterproofing membrane is waterproof, which can prevent external water from entering into the insulation structure of the building, protect the insulation structure from mold, degumming and falling, thus protecting the safety of users.Second, it is breathable.The unique microporous structure of the waterproof breathable membrane makes it breathable.Building insulation structure will inevitably get troubled with the water in the using process , even if it is sealed perfectly, it can also appear condensation phenomenon in the insulation structure which will form water in the insulation structure.If not dealt with in time, it will affect the normal use of building thermal insulation layer. So the waterproof breathable membrane protects the construction external thermal insulation layer well.
