ALORAIR Crawl Space Vapor Barrier, 10 mil, 10' x 65' Black/White Film

Homeowners, builders, and contractors looking to manage soil moisture in a crawl space can use this 10 mil polyethylene barrier as a protective ground cover. Its 10' x 65' roll is suited to encapsulation and other moisture-control applications.

The reinforced black-and-white film is designed to help reduce moisture vapor migration toward foundations, insulation, and structural components. Both sides provide vapor resistance, giving the material a practical role in crawl space projects and other protective uses.

Need a surface that also helps make a crawl space brighter? The white side reflects up to 90% of light, while the black side blocks light penetration, so each face offers a distinct benefit.

Pros

The two-sided design gives you useful options when laying out a barrier: use the black face to block light or the white face to reflect it. Anti-aging additives and reinforced construction are intended to help the polyethylene resist tearing during installation and long-term use. The smooth surface is easy to clean, which can be helpful when maintaining an enclosed crawl space.

For a project where a basic ground cover is the main priority, this film also supports crawl space encapsulation, moisture control, weatherproofing, and radon mitigation applications. It can serve as a moisture barrier beneath a home or as protective sheeting for other suitable projects, including greenhouse gardening.

Buyers generally praise the product’s quality, while feedback is mixed on thickness consistency, durability, moisture resistance, and value. These points reflect varied customer impressions rather than a single shared experience, the documented specifications identify this option as 10 mil polyethylene in a 10' x 65' roll.

Quick overview

This is a heavy-duty, black-and-white polyethylene vapor barrier measuring 10' x 65'. That roll size provides 650 square feet of coverage for planning a crawl space ground-cover or encapsulation project. The product line also comes in other thicknesses and sizes, so the 10 mil roll is one option within a broader range of project formats.

The black surface blocks light, and the white surface reflects up to 90% of it. Both sides are designed to resist vapor, while the smooth finish makes cleaning straightforward. For shipping and handling, the roll is packed in a sturdy cardboard box intended to minimize creasing and help protect the film before installation.

Who it’s for

This barrier is suited to homeowners, builders, and contractors preparing a crawl space for moisture control or encapsulation. It also fits projects that call for protective polyethylene sheeting, such as greenhouse gardening or weatherproofing applications. Compared with choosing a thinner or differently sized sheet, this 10 mil, 10' x 65' format is a defined option for projects where that thickness and roll coverage match the plan.

A practical project starts by matching the roll’s coverage to the area being protected and choosing which side best suits the space. The black face limits light penetration, the white face reflects light and can help maintain a brighter-looking crawl space. The film’s role is to help reduce vapor migration, adding a protective layer around the foundation environment.

Questions before you buy

What size is this roll? It measures 10' x 65' and provides 650 square feet of coverage, making the dimensions useful for estimating how much sheeting a project requires.

Can either side face the crawl space? Both sides provide vapor resistance. The black side blocks light, while the white side reflects up to 90% of light, so choose the surface according to the needs of the space.

How is the barrier packaged? The roll arrives in a sturdy cardboard box designed to minimize creasing and protect it during shipping and handling.
