Just finishing encapsulating our crawl space. Used the 12 mil diamondback, butyl tape, seam tape and foundation pins and couldn't be more satisfied. Work as promised and we were surprised how easy the 12 mil was to work with. Appreciated the helpful info on the website and even more the direct customer service. Called two or three times with questions and always got someone who was very helpful. Thanks again! Good to be almost done and even better to think we shouldn't have to do this again with quality products like these!

I was very pleased with the quality of materials and the relative ease of installation. You get high marks for quality, service, and an excellent website.

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 tape is excellent at sealing the vapor barrier seams together. It is very sticky and strong. Once its on the vapor barrier, its almost like it becomes part of the barrier.
