This is a quality barrier, and it is made in AMERICA. Besides doing my research on this wall barrier, and the company sells at a good price. My biggest reason was it was being sold in SC., and it is made in the USA. Thank you, and may God Bless you with an overwhelming amount of business.

Out of all of the products we have researched, this is the best option for stone foundations we have found, as well as the most cost effective. Easy to work with. There has been a noticeable difference in the air quality since it has been installed and we are only half finished! It has eliminated nearly all of the musty, basement odor. In the past, we have tried ionizers (which only masked the smell), and de-humidifiers, which helped but could not entirely remedy the situation.

Highly recommend the 20 mil for the floor of your crawl space. If you can afford it, use it on the walls as well. It is heavy duty and really makes a difference. Strongly recommend making accurate measurements and cutting it in a place where you can stretch it out as it comes folded onto itself.

I purchased the 7.75' wide by 86' long roll. I cut three equal length pieces outside, then folded the sections and transferred to the crawl space. You can just feel the quality of this material. I don't see it breaking down or ripping like regular poly sheeting. I joined the sections with 4" OSB Sheathing tape (which I had lying around) using about an 8" overlap. The tape stuck great and I'm thrilled with the final result. This was the final piece of a full crawl space encapsulation using 2" pink foam board on the walls and joist ends and bringing the vapor barrier up about a foot over the foam and taping there.

After much research, I finally took the plunge and ordered enough product to do a 1700 sq ft crawl space. When the pallet arrived, I was pleased at how well it was packaged for shipment. Lots of care to prevent damage during shipping. The quality of the 20 Mil vapor barrier far exceeded what I was expecting. Everything I ordered was top quality. I could not be more pleased with the outcome.
