I am very happy with this liner! At first I was worried because I could only get it 13.5 feet wide, but as it turns out, most of the supports under the house were about 12 feet apart, so it worked out great. It was cold where we installed the liner, and this stuff is really stiff when it gets cold, so we stored the role indoors so it would warm up. This helped a great deal. Also, unroll just the amount you need, then pre-fold it where your walls are, then roll it up again to get it under the house. This way it unrolls under the house and you don't have to manipulate it a bunch. Very good product. Highly recommended...

The items in this order were superb and did just what was needed as did all of the CrawlSpace materials. The encapsulation went well because the materials are excellent and the advice/directions were on target and very helpful. Also, the success was due to the staff at CrawlSpace Repair, their excellent advice, and the printed directions. I am a very pleased customer with the materials and service.

12 mil Vapor barrier is a quality product. Strong and easy to work with. If your planning to encapsulate your crawl space this is the right place to get all your materials. Excellent customer service and great installation advice. The humidity in my crawlspace is now between 40% and 50% even on the most hot and humid days. Smells coming from the dirt are also gone. Not sure why I waited so long to do this...oh yeah...working in a crawl space does kinda suck but once its done well worth it.

Excellent product. The 20mil thickness does make the product more difficult to work with. In the end, it is totally worth the slight additional effort. Laying this vapor control barrier in our crawl space changed it from a dirty, nasty environment, to being close to a sealed clean room. Huge differance!
