Viper CSX is a high performance crawl space vapor barrier designed to prevent moisture migration from the soil into the crawl space. Viper CSX helps guard against mold, mildew, allergens, fungus, radon gas, methane gas, heat loss due to damp insulation, wood rot and overall degradation of the crawl space. Viper CSX is a white, triple-ply, extrusion coated, virgin polyethylene membrane laminated to a high-density flexible foam core and metalized film. Viper CSX is manufactured using woven high-density fibers yielding high strength-to-weight ratio, tensile strength and puncture resistance. Weight Approximately 55 lbs per MSF
