NT-1600 Extra Heavy Duty Vapor Barrier - 12' x 50' NT-1600 Extra Heavy Duty Vapor Barrier - 12' x 50'

NT-1600 Extra Heavy Duty Vapor Barrier - 12' x 50' NT1600 is our most popular crawl space vapor barrier. It is an extra heavy duty vapor barrier for crawl space walls and floors. It is constructed with a 3 ply laminate combining 2 layers of U.V. stabilized coextruded polyethylene and a high strength cord grid. It is specifically engineered to provide high strength and durability in a lightweight material. Use NT1600 for crawl spaces that have regular traffic and are used for storage. It can also be used for perimeter walls to save money over heavier weight floor liners. Features Multiple layers and cord reinforcement resist punctures and tears. UV stabilization protects the material from degradation during extended exposure to sunlight. Cold-crack resistance eliminates failures in extremely cold temperatures. Low permeability greatly inhibits moisture transmission. Flexibility and light weight allow for easy handling and quick installation. Long life expectancy allows for significant cost savings through reuse and fewer replacements.

Always install a carbon monoxide detector in areas with combustion appliances.
