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.

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!
