I should not have waited so long. Used 6mill on side walls and 20 mill on floor. Very bright and a pleasure to go under house now. Easy to install and Larry at Crawl space repair was very helpful. Great product and $5000 dollars less than a local company wanted for lesser product.

Great vapor barrier! The Foundation Seal Tape and Waterproof Seam Tape worked extremely well, too. My customer is very happy with the overall outcome.

You can't find a better product out there! I do tons of research to find the best product. Not only is a superior product but it is also cost effective. I've been in construction for over 30 years and have seen what the standard 10 mil black plastic turns into.

I am very happy with the result since we converted a vented space that was a nightmare into one that was actually pleasant to be in. It should pay in utility bill dividends over the next few years.

This 20 Mil Silverback is the best. It sealed the floor and prevents thing underneath from penetrating it.
