12 Mil Reinforced Crawl Space Vapor Barrier - Various sizes

Product Description

The 12 Mil Reinforced Crawl Space Vapor Barrier is one of our most popular choices for crawl space encapsulation because it gives you strong protection without jumping all the way to our thickest material. It is a dependable, string-reinforced liner for crawl spaces where moisture control, durability, and a clean finished appearance all matter.

This white vapor barrier helps block ground moisture while standing up to the uneven soil, rocks, debris, and foot traffic that are common in crawl spaces. The 12 mil thickness and internal string reinforcement help reduce the risk of punctures and tears during installation and future crawl space access.

Use this liner across the crawl space floor, around piers, and on foundation walls when a white wall finish is preferred. Some installers use the same white material on both the floor and walls, while others use white liner on the floor with translucent liner on the walls for easier inspection behind the material.

For best results, overlap seams and use the right accessories during installation:

• Use Crawl Space Vapor Barrier Tape to seal overlapped seams.
• Use Vapor Barrier Staples to help hold the material in place, especially around edges, corners, and wall transitions.
