Feature and benefits:
with adhesive tape on the overlap for the sealing of junction, convenient for
application.
excellent weather resistance,corrosion, anti-aging, antioxidant.
it is excellent vapor permeable properties make it can be constructed on damp
surface, palisade structure internal water vapor flowing rapidly and effectively
avoid mould and condensing formation..
the surface has an function of antiskid to make sure the safety of application.
excellent tensile strength and elongation
big surface friction, closely integrated with the grassroots.
no smell,no taste, accord with environmental protection requirement.
Installation Instructions
Appilication key points
