This Spirecover vapor barrier is a true 10-mil-thick polyethylene film made from virgin materials – no recycled junk mixed in.
That means you get consistent strength and reliable moisture protection for your crawl space, basement, or under-slab area.


The material is odorless, tear-resistant, and reusable.
It does a great job blocking water vapor, steam, and even helps reduce radon gas penetration – which is a big plus if you're encapsulating a crawl space.


It's shipped in a roll to minimize creases, and packaged in a sturdy carton so it arrives in good shape.
