PVC Waterproofing Membrane
Product description
PRODUCT FEATURES
- Superior elongation, tension and little change to heat treatment.
- Great resistance to root, can use for plant roof construction.
- Excellent ability of puncture resistance, impact resistance and chemical corrosion resistance.
- Easy to apply, can be welded, stick firmly and environmental friendly.
- Good plasticity, which is very easy to deal with the corner and detail sections.
- Anti-UV, minimize absorb the quantity of heat.
- Good capacity of water vapour diffusion.
APPLICATION PROCESSES
- Pay off: Pre pave the membrane according to the site situation. If pave on the profiled steel roof, The pave direction should be vertical to the direction of steel sheet. Fix the membrane with design tools, cut the membrane if necessary
- Use welding gun or machine to weld the joints according to the relevant standards and rules.
- After large area construction, do a special extra fixation and sealant around the deformation joints, skylights and out-roof area.
PRODUCT MODEL
Model : H L P G GL
Width : 1.0mm 2.0mm
Length : 15m 20m 25m
Thickness : 1.2mm 1.5mm 2.0mm
NOTES
- The material of the welding place should be clean without water drop, oil and dust.
- Before official welding should do the pre-welding test, to make sure the welding temperature and speed.
APPLICATION METHOD
PVC waterproof membrane construction method: Mechanical fixation method, fully-adhered method and border adhesion method. Regularly the joints connecting will adopts the technique of hot air welding or special adhesive bonding glue.
The PVC membrane of CNPW requires to use the matched tools and follow the construction standard to ensure the construction quality.
