Radiant Barrier

RadiantGUARD® radiant barrier lowers your heating and cooling costs by reflecting radiant heat back to the heat source. This makes your home more comfortable both in the summer and winter months saving you money year round.

All our radiant barriers are double-sided highly reflective radiant barriers reinforced with a poly fabric scrim for tear and puncture resistance and are available in both perforated (breathable) and solid (vapor barrier) versions.  They install easily in either existing or new construction, requiring no special tools or protective clothing and reduce both heating and cooling costs making them appropriate for a wide range of applications.
