This is great quality 12mil vapor barrier, it is durable and works perfectly.if i had the money i would buy the 20 mil you could probably have a track meet on that stuff because the 12 mil was great!

Perfect product for my crawlspace. I am 75 years old and installed it myself in one week-end. Received the order promptly in three days. Excellent service and good experience all around.

This is an exceptionally strong product. I tried to tear a piece and found it not only would not tear but even getting it to stretch was very difficult. It lays out nicely and looks great. I am very happy.

We had an extremely wet spring this year and I had a strong musty odor coming up from the air returns into my home. The inside humidity rose to 81%. I contacted a contractor who happened to do work in a house with an encapsulated crawl space and thought it would be a good solution for me. Since encapsulating my crawl space and installing a dehumidifier and one fan, the humidity in my crawl space has dropped to a perfect 45% and the temperature is staying about 70 degrees. After just about one month, this seems to be a very good solution. The humidity inside my home is back to normal and the musty odor is completely gone.

I sealed my partial crawl space with this 12 mil liner along with the felt underlayment, foundation seal tape and seam tape. Delivery was prompt and the products easy to work with. No pvc smell at all. I should have done this years ago! I had extra so I added a second layer where I store tote bins. The seal is so tight that the liner puffed up due to air infiltration.
