Crawlspace vapor barrier supplier

GBA Editor | Posted in Green Building Techniques on

Does anyone have a national source for high performance vapor barrier? I want to offer something better than poly but am having trouble locating sources as well as performance information justifying the additional cost.

Thank you.

    I use Tu-Tuf #4 for sub-slab vapor barriers, which is pinhole-free, and much more puncture-resistant than conventional polyethylene films. It would be appropriate, as well, for crawl spaces. They also make an XF variety which is translucent rather than white and slightly ribbed for texture.

    It's available from Energy Federation wholesale division, which has warehouses in the East and Midwest.

    Crawl Space Care Technologies in North Carolina is perhaps the best company out there for crawl space encapsulation supplies:
