20 Mil Reinforced Vapor Barrier for Crawl Space Encapsulation
The 20 Mil SilverBack™ is made from 100% virgin polyethylene resin and reinforced with a 1000 denier polyester cord. This crawl space vapor barrier is idea for use on the crawl space floor because it is an actual 20 mil. We say it is an actual 20 mil because it is measured at the plastic and not across the raised reinforcement threads like other brands are. This makes the SilverBack™ 20 Mil 30% thicker than the competitors 20 mil.
Comparing product weights the 20 Mil SilverBack™ comes in at 110 pounds per 1000 square feet of product or 110 MSF while the closest competitor's 20 Mil is only 83 MSF and another 74 MSF.
The SilverBack™ brand is Made in America and does not contain unnecessary additives. There is no odor or off-gassing with this crawl space floor liner.
The SilverBack™ is easly identified by it's bright white face and silver colored back.
The 20 Mil SilverBack™ is available in 3 roll sizes:
- 6'9"x100' (675 sq ft) No welds or seams
- 13'4"x50' (675 sq ft) One weld/seam
- 13'4"x90' (1200 sq ft) One weld/seam
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.
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
The 20 Mil SilverBack roll size is approximately 86" for all three roll sizes. We take the wider rolls and fold them in half before rolling them on a thick cardboard core. This 20 Mil product will measure at least 20 mil (.020 inches) at the center of the diamond pattern and approximately 26 mil at the string reinforcement.
Expect that these rolls are heavy and may need two people to carry them, especially the 90' roll size (145 pounds). Due to its large size, UPS charges a large package handling fee of $9.28 each to deliver to your door.
