I used the 20 mil silver back vapor barrier and 4" tape in my crawl space. Both materials are first rate, and well worth the price paid. While working in a crawl space is not my favorite thing to do, I would not hesitate to use these materials from this company if I do get into another crawl space job. The materials were shipped - on all three of my orders - either the same day I placed the order or the very next day. Good material, great folks to deal with - whats not to like?

This seems to be a good, durable vapor barrier. Unfortunately, there were some holes in it from the shipper. I patched them with the seam tape, but it's unfortunate that there isn't a safer way to ship this stuff.

We installed the system in my crawl space over last weekend. Yes, I am very satisfied with the product. And yes, I am very sore, head to foot, from crawling over rocks to install it. I'm glad I purchased the reinforced material (20 Mil GuardianLiner™).

This is a very nice liner that helps create a quality vapor barrier. Will purchase again for the next crawl space encapsulation I sell. Also, product came quick and this company has great customer service.

The large roll, 13.5' x 90', of silver back was easy to get into the house, cut and maneuver in the crawlspace. Easy enough for a DIYer.
