Vapor Barriers

A vapor barrier is an important component in building construction. Its purpose is to help prevent water vapor from reaching a building’s walls, ceilings, attics, crawl spaces or roofs, where it can condense and cause building materials to rot or grow mold. Protect your property or building project with one of our vapor barriers from Aluf Plastics, Insul Barrier, Insul-Tarp and Viper. Browse our range of poly sheeting, radiant barrier, vapor barrier and waterproofing below.

To protect your crawl space(s), you should consider products like the Insul-Barrier Crawl Space Vapor Barrier, which provides a thermal break and moisture barrier, or the Viper CS Pier Wrap, which is makes vapor barrier installation for piers and pipes in crawl spaces simple. Another great product for pipes is the Viper Vapor Patch, which is a vapor barrier pipe boot/patch that has been designed specifically for pipe penetrations and patch work.

For an under-slab vapor barrier, we have great products like the Viper II Underslab Vapor Barrier and the Viper Venom Barrier, which protect against damage from water vapor and soil gas that can threaten the indoor air quality. The Insul-Tarp Under-Slab Insulation is a brilliant option for preventing moisture and mold from ruining your building work. To protect from moisture and dirt during your project, you may also like the Aluf Plastics Poly Sheeting.

If you’re still not sure which of our vapor barriers you need for your property, get in touch with our team on 281-657-1443 or via our Live Chat and they will be able to help you make the right decision for your project.
