For Conditions That Require Additional Mold Control
12 Mil Vapor Barrier for Crawl Spaces, GuardianLiner™ 13'4x50

Crawl Space Vapor Barrier

The Top-
Pure white top layer made from 100% virgin polyethylene resin. The bright white helps to give the crawl space a clean and tidy look along with making it easy to do regular home maintenance. 

The Middle-
The 12 Mil GuardianLiner™uses a polyester thread to reinforce the vapor barrier as well as to control any punctures from spreading. The reinforcement makes this vapor impossible to tear and requires a sharp knife to cut. The reinforcement is permanently imbedded in the middle by adding an additional layer of molten polyethylene resin between the top and bottom layers.

The Back-
The back is a cream/tan color and is also made from 100% virgin resin. This layer is home to the antimicrobial additive. Although products like the GuardianLiner™do not require an additive to resist mold and mildew we have added a small amount to inhibit any rare cases of mildew growth under the vapor barrier. 
The back is solid and has no pinholes or fillers like other popular brands.

The 12 Mil GuardianLiner™ is best used in a dirt crawl spaces with light to medium crawl traffic. If storage is necessary, the installer should lay a second layer of GuardianLiner™ on top of the encapsulation barrier to protect it from damage and wear.

This product was introduced to compete with other "12 Mil" products on the market and it is directly comparable to products like Duraskrim and NT1600, but without the pinholes and the excessive wrinkles. 

The 12 Mil GuardianLiner™weighs 60 MSF or 60 pounds of plastic for every 1000 sq ft of product. This weight is comparable to most other nominal "12 Mil" products offered by others.

The 12 Mil GuardianLiner™ is one of our most popular vapor barriers and like all of our barriers, this one is made right here in America. That means you get consistent quality and appearance. 

This crawl space liner offers an extremely high level of quality for the cost. Thanks to some recent engineering break throughs we are able to manufacture this high quality REINFORCED vapor barrier at an impressive price. 

12 Mil = .012 inches

Due to the expanding and rising UPS handling and shipping fees we are forced to add $9.28 at checkout for each roll.
