Double Bubble Insulation - Foil/Foil - 4' x 125' (500 sq ft)

EcoFoil Double Bubble Foil Insulation is very thin (1/4" to 5/16"), with a foil surface on each side. This insulation is rated and tested by reflectivity and emissivity. It is 96% reflective and 4% emmissive, meaning the product only allows 4% of radiant heat to pass through it. To put it simple, the insulation does not try to slow the way heat passes through it, the insulation tries to eliminate heat from passing through it.

This insulation is constructed of a double layer of polyethylene bubble insulation, bonded to two radiant barrier metalized sheets. The insulation not only works well to reflect radiant heat, but it also works as a vapor barrier, preventing condensation which can cause mold. EcoFoil Double Bubble Foil Insulation is primarily used for pole barns, metal buildings, basement walls, crawl spaces, and storage units. Our insulation can be used for both new construction and existing buildings. 

Important - You must tape any seams on the insulation. By doing this, the product acts as one sheet and maintains the moisture barrier. EcoFoil Double Bubble Foil Insulation is not to be used for under slab applications as the radiant barrier product is exposed. We offer a specific EcoFoil Under Slab Insulation where the radiant barrier is encapsulated between two layers of bubbles.
