1. spunbonded nonwoven fabric + polyolefin microporous membrane + spunbonded nonwoven fabric
2. spunbonded nonwoven fabric +polyolefin hydrophilic atreto-membran + spunbonded nonwoven fabric

Both two types of  Breathable membrane fabrics have the same functions:

• air-tightness —waterproof breathable membrane paves outside the insulation layer, covered up the integral building, effectively enhances the air-tightness of the building,reduces air leakage and heat loss.
• vapor-permeability—waterproof breathable membrane paves outside the insulation layer,to ensure effectively emission the vapor in the containment system to solve condensation moisture problem, protects the insulation layer.
• watertight—excellent tight of coated protects building against moisture and rain erosion which ensures the insulation effect and durability of the building, so as to make building more energy-efficient.

In addition,when breathable waterproof membrane in the process of construction, it will without doubt withstand the double trials of the strong ultraviolet radiation and extreme temperature, even in long-term contact and exchange of hot and cold air after construction completed,thereby the basic prerequisite for quality assurance is excellent anti-aging property

In term of the research report of NIST (National Institute of Standards and Technology) in 2005 shows that the use breathable membrane buildings’ heating and cooling energy cost saving of up to around 39%.That buildings are praised “breathing house”.

• UV-resistant

• flame resistant

• lightweight breathable membrane
