Commercial Grade Guardian is available in 12 or 20 mil thickness. Our 12 mil is the best choice for most crawl spaces. It is perfect for light traffic and medium storage. Our guardian liner is made up of 100% virgin polyethylene resin with an antimicrobial additive and is reinforced with polyester thread for maximum tear strength. Our liner consists of 3 layers: top, middle and back. The top layer is bright white and will keep your crawl space clean and tidy year around. Middle layer is a polyester thread to reinforce the vapor barrier as well as to control any punctures from spreading. The reinforcement makes it impossible to tear and requires a sharp knife to cut. The reinforcement is embedded by adding an additional layer of molten polyethylene resin. The back layer features an antimicrobial additive to inhibit any mildew growth.
Crawl space encapsulation improves the homes overall health and comfort. In the last 10 years, the concept of sealing a crawl space has grown in popularity. Most of this is because of the results it delivers when it is done properly.
Our Guardian Liner comes with a 25-year manufactory warranty.
