Man this tape is worth the extra cost. I've been doing this for 12 years and no other tape compares at all. Not even close. If you are in this business and you save $12 on a 187 foot roll, you're really doing a disservice to the client by using a lessor brand. watch out for mimics too. Some are trying to make their tape look like this ST4

Your 12 mil. Vapor barrier is a very good product. Should hold up for a lifetime. Thsnks for your rapid delivery.

Loved it. Mold Remediator, Water Restoration.

The Vapor barrier was a Pleasure to work with! High Quality

I will not use another brand!

I used this vapor barrier for the foundation walls and pillars. It is much easier to cut than the thicker equivalent for ground use, which I also have. This is the same as the ground barrier, just a little thinner. They have both done an outstanding job, and now I'm waiting for the next few months to see how well they keep the moisture out of the crawl space. So far, everything is dry.

Great product, easy to use and install, very knowledgeable and helpful staff.
