Our 20 mil Vapour Barrier is designed to withstand the toughest conditions and hold back any moisture from penetrating through the film.
Available in the following sizes:
- 20mil – 20′ x 100′
Our 20mil CGSB certified Vapour barrier is a special purpose construction film to be used as a long lasting vapour barrier. It is designed to exceed the criteria specified in C.G.S.B. Standard CAN/CGSB-51 34-M86 & can be used under concrete slab or to protect any crawl space area.
Our Vapor Barrier is produced from Virgin polyethylene resin & comes with UV additives that prevent against premature degradation & ensure resistance to UV light.
