Working Drawing

• High tear and puncture resistance.

• Resistant to mildew and corrosion through acids, alkali, salts and other media in the use environment.

• Heat and low temperature resistance, excessive adaptability to the building environment.

• Easy Installation. With "Velcro" adhesive tape, it can be at once bonded to the non-woven buffer layer (self-adhesive cloth) , no hidden hazard of nailing and perforation , the development effectivity is higher.

• Perform each water resistant and drainage functions, and the water-proof impact is extra significant.
