Excellent product, the only reason I rated 4 and not 5 stars for durability is that this is a recent installation and I will know more about durability in 5 - 10 years. I am certainly not expecting any issues based on what I've seen. Perfectly sized to work with a 1/4 inch drill bit. They are easy to install but once in, I think would be difficult to pull out.

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've put the 12mil silver back on my concrete walls and 20mil on the ground in my crawl space . Very satisfied with both products . Thank you crawl space repaire .

I had quotes from multiple big companies to "encapsulate" my 1945 dirt and damp basement with only 6ml plastic. A true encapsulation wouldn't work in my basement, and would only increase the risk of termites. I chose this product after researching various plastics and reading studies on different levels of VOC toxicity. My handyman did a great job cutting to fit and used tape and a few round crawlspace stakes to fasten to the dirt banks. Very happy with the result, I have a much higher quality vapor barrier for a fraction of what the larger companies were going to charge.

This product is great. Dropped the humidity from 85% to 30% almost instantly and the vents havent been closed yet. Well worth the money. I'd also add that the service was exceptional both before I bought this product and after. When I got to the job I realized that I was going to need felt. The company shipped it to me within a few days so I was able to complete the job while on site. I highly recommend both the product and the company.
