NEW Product Technology

The SilverBack™ HS's technology comes from 60 years of outdoor environmental strength testing and is a premium engineered vapor barrier. With 100% of the surface protected by reinforcement made from strengthened polyethylene ribbons. The puncture and tear strength greatly outmatch even our SilverBack™ string reinforced vapor barrier product line. The minimum thickness across the even surface is 20 Mil, but installs like a 12 mil, making it much easier to lay in a crawl space environment. 

This crawl space vapor barrier is made from 100% virgin polyethylene and reinforced with virgin polyethylene ribbons. The ribbons are stretched to strengthen them before they are woven in a cross hatch pattern.

This product technology is entering the market at a time when rising polyethylene resin and manufacturing costs are making string reinforcement options too expensive for many homeowners and professionals alike. The New SilverBack™ HS resets the clock on the manufacturing costs of engineered vapor barriers while dramatically improving the performance and features required for a crawl space vapor barrier.

Look at the strength test comparison of the NEW 20 Mil SilverBack™ HS and the 20 Mil SilverBack™ SR under the "Specification" tab.

One roll did a 200 sq ft room addition with about 18" going up the sides. Laid it out in the street, taped both seam sides, and carried it over to the open crawl space, Dropped it in and cut the corners. You could build a nice swimming pool with this vapor barrier!

This is a quality barrier, and it is made in AMERICA. Besides doing my research on this wall barrier, and the company sells at a good price. My biggest reason was it was being sold in SC., and it is made in the USA. Thank you, and may God Bless you with an overwhelming amount of business.

  • Limited sizes
I purchased the 7.75' wide by 86' long roll. I cut three equal length pieces outside, then folded the sections and transferred to the crawl space. You can just feel the quality of this material. I don't see it breaking down or ripping like regular poly sheeting. I joined the sections with 4" OSB Sheathing tape (which I had lying around) using about an 8" overlap. The tape stuck great and I'm thrilled with the final result. This was the final piece of a full crawl space encapsulation using 2" pink foam board on the walls and joist ends and bringing the vapor barrier up about a foot over the foam and taping there.
