What is the difference between multipurpose polyethylene film and the ULTRA + vapour barrier?
Multipurpose polyethylene film is used for various jobs such as protecting surfaces and furniture while sanding and painting, building temporary shelters, doing garden work, etc. The ULTRA + polyethylene vapour barrier, manufactured in compliance with CAN/CGSB51.34-M86 standard, is used in walls to create a continuous, impermeable barrier to protect building insulation. Many manufacturing specifications are imposed to assure users a uniform, high-performing product. For example, a UV stabilizer and an antioxydant (preservative agent) are added to ULTRA + Vapour barrier to keep sun light and heat from degrading the film. This treatment also increases product resistance to cracks. These types of additives give the ULTRA + Vapour barrier a much longer life-span than the multipurpose polyethylene film.
