Our take on the Alorair 12mil Crawl Space Vapor Barrier 10'x100'

This is a 10 ft by 100 ft roll of 12 mil black polyethylene film, sold as a crawl space vapor barrier and general heavy-duty sheeting. At 12 mil it is thicker than common 6 mil hardware-store poly, so it resists tears and punctures better during install and reuse. It suits crawl space encapsulation, under-slab and basement moisture blocking, and jobsite or renovation protection. The trade-off is weight: a 50 lb roll is awkward to carry and unroll alone, and a single 10 ft width means seams on wider floors.

Questions and answers

Is 12 mil thick enough for a crawl space vapor barrier?
Yes. 12 mil is well above the 6 mil minimum many builders use and is a common choice for encapsulation. Thicker film resists punctures from gravel and debris better.
How much area does one roll cover?
A 10 ft by 100 ft roll covers 1,000 square feet. Overlap seams and allow extra for walls and posts, so plan on less than the full area in practice.
How does it compare with 6 mil poly?
It is twice as thick, so it is heavier, tougher and less prone to tearing during install. It costs more and weighs more, which matters if you are working alone.
Can it be used above ground, like for paint protection?
Yes. It works as a dust cover and drop cloth for renovation and paint protection. The smooth surface cleans up for reuse.
Does it come in other sizes?
The same line comes in 10 mil, 12 mil and 14 mil thicknesses and several roll lengths, plus a 6 mil 12 ft wide roll for large areas.
Does it have a warranty?
No written warranty is stated. Inspect the roll for damage before installation.
