Unlike traditional insulation this product is not rated by an R-value. Bubble insulation is rated by its Reflectivity and Emissivity. R-values are based on thermal resistance (how long heat takes to pass through the product), the thicker it is the higher the R-value. Bubble insulation is very thin, 18" - 316", but has a high reflectivity, 96%, and a low emissivity, 4%. Only 4% of radiant heat passes through the insulation, simply put we are not trying to slow the way heat passes through the insulation but trying to eliminate heat from passing through it. Single bubble foil insulation is available in either a foilfoil option or foilwhite option. Both products perform the same, the white is just a cosmetic difference. Do you want a foil interior or a white interior? Single bubble foilfoil insulation is constructed of a single layer of polyethylene bubble insulation bonded to two radiant barrier metalized sheets. The Single Bubble insulation not only works well to reflect radiant heat, but it also works as a vapor barrier, preventing condensation which can cause mold. Remember all seams must be taped so the product acts like one. Single bubble foil insulation is lightweight and easy to install.
