ALORAIR Crawl Space Vapor Barrier, 10 mil 10' x 100' Black/White Film

Some crawl space projects call for a roll selected by its thickness and coverage, others prioritize a surface that also works for different protective applications. The ALORAIR Crawl Space Vapor Barrier is 10 mil polyethylene sheeting in a 10' x 100' roll, designed for crawl space encapsulation, moisture control, and weatherproofing.

Its black-and-white, double-sided design gives each side a practical role: black blocks light, while white reflects up to 90% of it. Both sides provide vapor resistance, so you can choose the surface orientation that suits the space.

Use it as a ground cover beneath a crawl space encapsulation project, or consider it for greenhouse gardening and other protective applications. The roll arrives in a sturdy cardboard box designed to minimize creasing during shipping and handling.

Key takeaways

This heavy-duty polyethylene sheeting helps reduce soil moisture vapor migration, adding a protective layer for foundations, insulation, and structural components. For homeowners, builders, and contractors planning crawl space work, the 10 mil thickness and 10' x 100' format provide defined material dimensions to plan around.

The reinforced black-and-white film includes anti-aging additives and is designed to help resist tearing during installation and long-term use. Its smooth surface is easy to clean, making it practical for an area where the barrier may need routine attention. The black side blocks light, the white side reflects up to 90% of it, which can help maintain a cleaner, brighter crawl space environment.

This barrier is also suitable for moisture control and radon mitigation applications. Those uses make it relevant beyond a basic ground cover, while its roll format can suit projects planned around continuous sheeting rather than purchasing material in smaller pieces.

Cleaning & care

The smooth film surface is easy to clean. For crawl space use, plan the layout around the 10' x 100' roll and orient the black or white side according to the light-blocking or reflective surface you want facing the space. Both sides provide vapor resistance, so the choice of side can be guided by that practical preference.

The cardboard box packaging is designed to help minimize creasing while the roll is shipped and handled. Keeping the material organized as you prepare the installation can make it easier to work through a project that uses the full roll dimensions.

Who it’s for

This vapor barrier suits homeowners, builders, and contractors working on crawl space encapsulation, ground coverage, or moisture control. It can also serve greenhouse gardening and other protective applications where a black-and-white polyethylene film is useful. For example, someone preparing a crawl space can use the sheeting as a ground-cover layer while selecting the black side to block light or the white side to reflect it.

It makes sense if you want a heavy-duty, double-sided barrier in a specific 10 mil thickness and 10' x 100' roll size, rather than choosing material by smaller individual pieces. The smooth surface, reinforced design, and protective packaging support practical handling from delivery through use.

Should you buy it?

Choose the ALORAIR roll when your project calls for polyethylene sheeting designed to reduce moisture vapor migration and you value having two functional surfaces. The black side blocks light, the white side reflects up to 90%, and both sides provide vapor resistance. Its stated applications include crawl space encapsulation, weatherproofing, moisture control, radon mitigation, greenhouse gardening, and other protective uses. For a planned crawl space or ground-cover project, the 10 mil, 10' x 100' format gives you a clearly defined roll to work with.
