Roll Size - 48" x 125' (500 sf)
This white double bubble insulation roll is 500 square feet and measure 48" by 125'. This white poly/foil product is made with two layers of polyethylene bubble insulation and then covered on one side by reflective foil and UV rated white polyethylene sheet on the other. The white double bubble insulation works to reflect radiant heat and also performs as a vapor barrier to prevent condensation. To create a vapor barrier with white double bubble insulation, be sure to seal it properly with white polyethylene tape.
White double bubble insulation works well in pole barn/post frame buildings for both the walls and roof but is also best for basement wall insulation, garage door insulation, and several other applications. The white/foil combination on this reflective insulation provides a finished, clean look.
