This 12 mil vapor barrier is excellent quality and seems extremely durable. I have put down a little over 2000 sq. ft in my crawl space. It is flexible enough to work with, but very strong. It was shipped extremely quickly and came VERY well packaged. I found the price to be completely reasonable. I highly recommend it.

This is a good product that performs it's job well in a crawlspace. The only drawback is that it's so thin that when you get down to a third of a roll it gets a bit harder to use. Tip- always order an extra roll for three you think you will need.

I would highly recommend buying this product when doing a "dry lock". I would buy again!!

this product was top notch, I would recomend it to anybody and the help I got from larry was as good as it comes. best part,made in the u.s.a!

Moldstoppers of MD has been involved in crawlspaces for years - whether installing or contracting them. We have seen good tapes and we have seen bad tapes. Believe me the amount time it takes to do one of these projects correctly can all be undone by using the wrong sealing tape. This product has the advantage of being wider. Remember your under a house. Cuts can get a little crazy. A wide tape is important. Also it doesn't separate - even in extremely moist conditions. Terrific product
