    12 Mil Reinforced Vapor Barrier for Crawl Space Encapsulation

    The 12 mil SilverBack™ crawl space vapor barrier is the best product to encapsulate a crawl space. Used by professionals to achieve results that back up their reputation.
    This product is made in the USA and from premium grade ingredients. We do not cut corners on our products. The SilverBack™ crawl space vapor barrier naturally resists mold and mildew, does not offgas any odors and will not delaminate.
    The Top-
    The face is pure white with a slight glossy finish. You will notice the diamond pattern string reinforcement throughout the product. The pure white finish gives this crawl space vapor barrier a clean and finished look once installed.
    The Middle-
    In the center of the vapor barrier is a polyester cord that is secured into place with a molten layer of virgin polyethylene. This reinforcement will stop tears and contain any puncture damage to the area of initial damage. This reinforcement cord is very similar to the ones used in tires to keep the rubber from coming apart from the centrifugal force of rotation. The bond of the molten layer of polyethylene is superior to simply trying to remelt the front and back layers together. By introducing the molten layer it brings all the surfaces to the same temperature allowing a bond that is not just "remelted" but rather liquified together. This bond insures the SilverBack™ will never delaminate or allow air bubbles into the center.
    The Back-
    The back of this vapor barrier is silver in color and made from the same virgin polyethylene as the front layer. The color additives are for appearance only and do add a bit of cost to the product manufacturing. However, the color does not weaken the barrier in any way.
    The 12 Mil SilverBack™ is the best all around choice for most crawl spaces. It will handle light to medium storage requirements as well as traffic for regular home maintenance. If the SilverBack™ is going to be installed over sharp stone consider installing our Felt 550™ first to protect your SilverBack™ investment. This is the most popular SilverBack™ vapor barrier for crawl spaces due to its lower cost and high performance.
    Made 100% from premium grade virgin polyethylene resin. This Commercial Grade 12 Mil vapor barrier is true thickness, so our 12 Mil measures 12 Mil at the barrier not the string reinforcement. You get the absolute best quality and performance as well as the technical support you need to install our products and answer your questions.
    This 12 Mil SilverBack™ vapor barrier weighs 65 pounds (of plastic) per 1000 square feet. Compare that to the competitions 12 Mil @ 38 pounds per 1000 square foot. That is a 27 pound less per 1000 sq ft roll in material you are paying for.
    12 Mil = .012 inches

    The 12 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 12 Mil product will measure at least 12 mil (.012 inches) at the center of the diamond pattern and approximately 17 mil at the string reinforcement.

    Expect that these rolls are heavy and may need two people to carry them. Due to its large size, UPS charges a large package handling fee of $9.28 each to deliver to your door.

    Cleanspace 12 mil Silverback

    This is a great product. Thick and tough enough to lay over dimpleboard to line a crawlspace floor, light enough to work with easily in tight spaces.

    Excellent product

    • quality
    • heavy duty
    • spiffy silver backing
    I had quotes from multiple big companies to "encapsulate" my 1945 dirt and damp basement with only 6ml plastic. A true encapsulation wouldn't work in my basement, and would only increase the risk of termites. I chose this product after researching various plastics and reading studies on different levels of VOC toxicity. My handyman did a great job cutting to fit and used tape and a few round crawlspace stakes to fasten to the dirt banks. Very happy with the result, I have a much higher quality vapor barrier for a fraction of what the larger companies were going to charge.
