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.

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!

I cannot recommend this product enough. We installed it in our crawl space after the Colorado floods in 2013. After installing it, our crawl space has been warm and dry and we have had no mold issues. I was hesitant to use the foundation pins, but the person we talked to said we really needed them, and he was right. We were able to rent a "pin gun" from our local hardware store and the combo of the pins plus the caulking has held up extremely well. In this day and age of bad customer service and poor quality products that look good but don't deliver, it is nice to find a product that does what it says it will and exceeds your expectations. Highly recommend.

My son and I installed the 20MIL Silver Back vapor barrier in our 11x22 dirt floor crawlspace. The product is excellent and I couldn't be happier. The 20MIL liner is nice and thick and tough, so Rubbermaid tubs and boxes we store in the crawlspace scoot cross the liner with no problems and no chance of tearing the liner. I couldn't believe how fast it came! I ordered it online, the next day it was here! Would highly recommend it to anyone considering lining their crawlspace.
