Vapor Barrier

4 mil. polyethylene plastic for the do it yourself home owner. Don't make the mistake of going to the hardware store and purchasing the 10x100sq. ft. roll. Big Mistake…You probably will save a few bucks but the task of unraveling this monster is not worth the savings. Remember, you have to accomplish that task under the home in a tight space. http://www.pestcontrol-products.com
