VERY COST EFFECTIVE. REQUIRES TWO PERSONS TO INSTALL.

I spent hours laying out this stuff. While doing this I proceeded to roll and crawl all over it to anchor it to the walls, tape seams and cut around posts. There wasn't a single tear in the material after all of this. I feel fairly reassured that this will hold up pretty well.



Despite the material's resistance to my movements, it was still relatively easy to cut with a pair of regular scissors (no fraying at the ends either) and the drill bit went right through when it came time to put the anchoring pins in. As long as you aren't making a habit of throwing your sharp tools carelessly around on it then everything should be fine.



The material is still easy enough to fold and bend around corners. There was a little more bend resistance than the usual 6-mil material but it didn't cause me any trouble.



I do like that this was available in a smaller size. I was only dealing with a 12'x16' addition crawl space and didn't need anything more than the 4'x80' roll. It gave me plenty to work with in case of mistakes without leaving too much excess left over.

Very good product, only thing it should be shipped in cardboard had a couple holes in lost 3 feet, from ship other than that good stuff

The Silverback vapor barrier seems to be very durable and easy to work with. I did a lot of leveling of the gravel in my crawlspace which made everything relatively square. I can see how an irregular surface may lead to a more difficult installation.

Larry really simplified a job that I thought was going to be a nightmare. At his suggestion, I encapsulated my crawl space with the 20 Mil SilverBack™ and added an AprilAire dehumidifier. Now I am one happy, satisfied customer because there is no more water running off ducting and I finally have a crawl space that is dry.
