## Description

EcoFoil Double Bubble Reflective Insulation (White/Foil) is constructed with a double layer of polyethylene bubbles bonded between a layer of 99.9% pure aluminum radiant barrier on one side, and a sheet of smooth white polyethylene on the other side. All radiant barriers need at least a small amount of air space on both sides for the foil to reflect properly. Our double bubble foil insulation can be applied inside basement walls or between floor joists and serve as both an insulator AND a radiant barrier, because the double bubble layer provides maximum R-value, as well as that air space which the foil needs to properly reflect radiant heat. EcoFoil reflective insulation works especially well in metal and post frame buildings because it is designed to reduce radiant heat gain/loss and eliminate condensation. When applied inside a wall, ceiling, or other area, the reflective foil side BLOCKS 97% of radiant heat coming into your building in the summer and traveling out in the winter &#x2013; and directs that heat back to where it came from. Meanwhile, the white poly side (which is water resistant and easy to keep clean) provides a finished appearance to the inside of any structure. This &#x201C;green&#x201D; insulation will pay for itself quickly, by significantly reducing the amount of heat leaving or entering any building or living space where it is applied - making your environment more comfortable while reducing overall energy utility costs.
