I used this 20 mil Silverback on the floor of our crawl space due to the excessive rocks. It was the perfect choice as it is tough and won't wear through. The folks at CrawlSpaceRepair.com did an excellent job of guiding me through the installation process. Very easy.

I used 20 mil SilverBack HS on the floor of my crawl space over Felt 550. It is thick, strong, but flexible to work with. Air quality is almost as in my room. I enjoyed working with it so much that now I plan to help my friends do that same thing in their house

Product was just as advertised. Received in just a few days and was a breeze to install.

 

looks tough and much better than plastic film.

Used this product to encapsulate an 18 x 24 foot area in a new construction crawl space. The overall task was easy and the finished product looks great! I used white Gorilla tape to seal - matched perfectly and was more economical than some of the other tapes. Was also able to roll up on the walls to attach Silverback to the wall instillation. In total it took me a 3 hours, but most of the time was to move household items while installing the product.
