The easiest and best way to stop heat transfer between ground and concrete slab for greater energy efficient living is with Low-E Under Slab Foil Insulation Rolls for Radiant Heat.

Build energy efficient structures from the ground up by using revolutionary ESP LOW-E SlabShield. Developed with the same ESP LOW-E energy efficient technology that goes into all LOW-E Radiant Slab Insulation products, SlabShield offers unique benefits not found in other under slab products. LOW-E SlabShield is engineered to not only help prevent heat transfer from ground to slab but also to provide a vapor barrier that protects basements from excess moisture .

ESP LOW-E SlabShield Foil Insulation for Radiant Heat is designed with a layer of closed-cell polyethylene applied to both sides of a reflective foil layer. The closed cell doubles as a vapor barrier and a protection for the aluminum against chemical reaction with fresh concrete. LOW-E SlabShield is puncture resistant up to 93 psi and crush resistant up to 70 psi. Unlike other rigid under slab insulation, LOW-E SlabShield adjusts and molds itself to the contours of the grade providing a better and stronger concrete pour.

Slab Shield Under Concrete Radiant Slab Barrier Insulation is made to withstand harsh job site conditions  easy to use and works for many different applications

ESP LOW-E SlabShield is easy to apply and will not crack or break like traditional board insulation when walked on. It is lightweight and cuts easily with a utility knife. LOW-E SlabShield comes in rolls with innovative inter-locking tabs that provide a perfect seam when using several rolls side by side.
