Whitecap - Crawl Space Vapor Barrier - 20 Mil (12' x 100'), Thick Plastic sheeting, Drop Cloth Moisture Barrier Covering for Crawl Space Encapsulation, Heavy Duty Polyethylene, White Woven Sheeting

We like the thickness 20mil vapor barrier. We used it to seal off the bottom of our 40 ft RV for winter. Definitely feels durable and will be able to withstand the harsh winter weather and winds on the mountain top in West Virginia.

This is very heavy duty stuff. I used it as a moisture barrier in the crawl-space under my house. Seems to be working good.

This product is as described. Very pleased and highly recommend. Company and the products they sale are on point! Bonus: Customer services is AMAZING if you need help with anything!!!

It was exactly what I needed at a good price

This plastic sheet is very useful. I wish I would have got the thinker version, but the 12mil is still doing great and hold up well. I'm using some of this as a moisture barrier under a small shed. Using some of it for additional weather protection for other small buildings, too. It has been working great and holding up well. It was easy to install and seems to be very durable.

At what are this for I construction job and it Is fantastic and easy to install very durable!

Purchased to encapsulate crawspace, went great. great product.

Excellent communication and superior product. I've worked with many underlayments and VB's and this product meets professional expectations. What is more important is My DIY Center's excellent customer service. After having a shipping/damage issue, they handled the problem professionally within an hour of communicating the problem. Will use again.
