We doubled up the extra material in the areas that will experience high traffic areas. Easy to install and maneuver.

I had my crawl space encapsulated a year ago, and several months later I started noticing a strong odor after a hard rain. The odor would work it way through the air vents into the living space. I called Larry after reading his blog on the web, and he suggested this fan. I installed about 65' of thin wall pipe under the plastic on the ground and vented it out of an existing vent. The smell was gone within 12 hours! I also like the fact that it comes with a 5 year warranty. Thanks!

Once I understood what this was, I ordered and used 5 rolls. I covered my entire crawlspace floor with it prior to putting down the vapor barrier. It is strong and really is just what I was looking for.

I bought this product due to having a lot of sharp rocks in the crawl space and I was worried about the vapor barrier getting punctured. I laid the product down and it well worth the money! It’s tough and will dull box blades pretty quick. Had to use a knife to puncture holes in the felt due to my garden staple last not poking through. Plus, I think it will help keep the VB clean when applying it. Only bad thing is that it cost a bunch to ship but I guess that is part of it since I’m in Oklahoma.

Outstanding product. Very thick and durable. No doubt this product will last.
