Favorite crawlspace liner

joenorm | Posted in General Questions on

Does anyone have a preferred brand of crawlspace vapor barrier.

Needs to be a light color and 10 mil or thicker. Looking to cover 1100 sqft.

    I'm in the same boat and about to order the liner for our crawl. I'm looking at 20mil (based on the PDF from this site). Given that there's a picture of fiberglass batts between the joists on the post remediation pictures on that article, I hope that one of the pros here gives updated suggestions.

    Joe, Stego and Viper both have thick, white, durable crawl space liners. Viper has several options, depending on your needs. I have also used Tenoarm which is tough stuff but only 8 mils.

    Americover has a lot of options up to 20mil, and reinforced too if you want it. I’d go with their white option if you use their product.
