We used this with the felt mat also available on this site. So far we have installed the barrier only on the floor and we plan to install rigid insulation on the walls next weekend. The musty smell in the basement is greatly reduced already and the whole house smells better even though we haven't finished the entire project yet.

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.
