LOW-E ESP 4FSFB-100 Slab Shield Insulation, 100 ft L, 4 ft W, Polyethylene

SlabShield insulation was designed specifically for use under concrete slabs. The product gives you a vapor barrier and significant thermal performance in one user-friendly product. The products have a layer of closed cell polyethylene foam applied to both sides of a reflective layer. The closed cell foam is a vapor barrier and protects the aluminum from the chemical reaction that would occur with uncured concrete. All you need to apply SlabShield is a razor knife and tape. Simply roll the product to the desired length and cut. Compare that to working with 4 x 8 ft board insulation and you'll soon see the time savings of working with SlabShield. Another difference between SlabShield and the foam boards is its ability to mold itself to the contours of your grade. SlabShield is flexible enough to adjust to the high and low areas helping to create a stronger finished concrete pour. SlabShield also does not crack or crumble when faced with the normal abuses the job site throws at it.
