The 675 Sq Ft rolls of 20 Mil SilverBack™ vapor barrier were quite heavy. This speaks for the true quality of the material. I have prior experience with a competitor's crawl space liner that was advertised as a 90 mil liner, which weighed less than half as much as the 20 Mil SilverBack™ from CrawlSpace Repair. I am very happy with the customer service and the quality of the materials I bought from CrawlSpace Repair. My mother's crawl space is now clean, bright, and beautiful.

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.

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.

Definitely recommend the product! Solved the house odor issues immediately. Worth every penny. The sketches provided by Larry were exactly what we needed to do the job right the first time without any "redos". Very happy with the product!
