Our Vapour Barrier is designed to withstand the toughest conditions and hold back any moisture from penetrating through the film.
Available in the following sizes:
- 6mil – 10′ x 100′ and 20′ x 100′
- 10mil – 10′ x 100′ and 20′ x 100′
- 15mil – 20′ x 100′
- 20mil – 20′ x 100′
Our 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.
