I wasn't sure is i was going to buy this tape or some from a local store. I am glad I did. The quality and size of this tape were excellent for ceiling vapor barrier. Adhesion was excellent.

The 12-ml Silverback was packaged perfectly, altho you may want to put some tips for unwrapping! I was able to lay down two pieces to cover most of my crawl space, and finish with the left-over pieces, and I'm very happy with the results. My only comment would be that I was a little surprised that the 13' pieces had a seam, and the seam was not sealed down. I don't want to use seam sealer tape, but I also don't like having a loose edge that can catch things moving across it. I may seal it with some adhesive... but a minor issue. Overall, I'm thrilled with the installation information provided, the excellent customer service, and the good quality barrier.

With rock hard chunks of clay and sharp pieces of concrete debris all around, anything less then 20mil would have been a disaster. If I had to do this job again, I would have gotten 2 six foot wide rolls rather then the 13 foot wide roll. The 13 foot width was very difficult for my brother and me to manage when your on your knees and belly.

This is to let you know I am very happy with the quality of your product and the fast shipping. I certainly would recommend your product to others.

I'm very happy with the 12 Mil GuardianLiner along with everything else I ordered from the website. Shipping was very fast! Great company!
