20 Mil SilverBack™
Reinforced Vapor Barrier for Crawl Space Encapsulation

This vapor barrier actually measures 20 mil at the plastic, not the thread.
20 Mil Vapor Barrier SilverBack™ 13'4"x50'

The top of the 20 Mil SilverBack™ is a brilliant white. This clean white color helps to reflect light in the crawl space and give it a pleasant appearance. The top layer is made from 100% virgin polyethylene resin to give the absolute best performance and last a lifetime.

The Middle-
The middle of the 20 Mil SilverBack™ houses the polyester thread reinforcement. This reinforcement has one job and that is to eliminate tearing. The grade of polyester cord is the same that is used in tires to keep the rubber stable at highway speeds. The reinforcement is permanently embedded in the vapor barrier with an additional layer of molten polyethylene. This insures the 20 Mil SilverBack will never delaminate.

The Back-
The back of this product is a silver color, which is the trademark of the SilverBack™ brand. Color additives do add cost to the product, but we view this cost as necessary to help homeowners and contractors know they are buying a genuine quality product. The back layer does not have pinholes or fillers and naturally resists mold and mildew. 

20 Mil SilverBack™ is thick enough and strong enough to allow for medium to heavy storage, heavily traveled areas and to cover stone/concrete floors. We still recommend the use of the Felt550™ if the floor has objects that are sharp and can not be removed.

The actual 20 Mil thickness of the 20 Mil SilverBack™is one of its strongest features. We measure actual thickness at the plastic, not the reinforcement thread like others do. See the video below to see how it is measured and compared to the competition.

The SilverBack™ 20 Mil vapor barrier weighs 109 pounds per 1000 square feet or 109 MSF. Compare that to the competitors 20 Mil @ 74 pounds per 1000 square feet. That's 35 pounds less plastic for the same money as the SilverBack™.

Use the 20 Mil SilverBack™ on the floor and the 12 Mil SilverBack™ on the walls to keep the costs inside the budget. 

20 Mil= .020 inches

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