This vapor barrier is very tough. Even over an area where I had stone base the vapor barrier didn't fail. I've crawled over it now many times and only have seen some minor strain marks on the stone. This product is tough but easy to work with. Highly recommend it!

Excellent product.

So far I could not be more pleased with the white/silver liner I ordered to be installed in the crawl space of our home. I had obtained an estimate from a local company that specializes in crawl space solutions. The installed price was over $6,000. After some on line research I found your site and product information. The liner I purchased is very comparable with what the contractor uses. I could not afford a solution totally comparable to the contractor's solution which did have other components I chose to eliminate, but I believe this was a great compromise. Compromising saved me over $4,000!

I was considering 20 mil vapor barrier on the recommendation of a spray-foam contractor, but after reading the specs and knowing that I was installing on plain dirt and won't be storing anything on top of the barrier I decided to go with the 12 mil. The 12 mil silverback is really durable, but easy to cut with a razor knife and easy to work with in a confined space as long as you cut it to size and fold it correctly prior to taking it into the crawl space with you. I cut the pieces to size (piecing together where needed with the tape, since the roll was 13'4" and my crawl space is 17x21. I cut it 1 foot longer and wider than the crawlspace dimension to allow it to go up the foundation wall by 6" all the way around. (The spray foam insulation will seal the edges to the foundation block). When folding it, I chose to fold it from the outside edge towards the middle - with the two long edges meeting in the middle. Then I repeated the process and folded the resulting long, narrow piece in about 3-foot squares. Using this method allows you to position the folded barrier in the center of one end of the crawlspace, unfold it length-wise, then kneel in the middle and fold each side out to the sides. The whole process was pleasantly much simpler than I anticipated, with the exception of getting covered in spider webs.

 

Even tho it wasn't the easiest installation because of the issues with this old house, it ended up great. Product is durable and simple to install overall. Just installed it, so we don't have any history with it. If if works as well as the installation went, we will be very happy.
