Roll Size - 48" x 75' (300 sf)
This double bubble white foil insulation roll has the lowest square footage of the white double bubble insulation rolls which makes it a good size for smaller projects. Like all double bubble white poly/foil products, this 300 square foot roll is made with two layers of polyethylene insulation bubbles attached on one side to reflective radiant barrier made of aluminum and the other side to a white polyethylene sheet. To install double bubble white foil insulation properly, ensure that you seal it with matching white tape. This approach produces an effective vapor barrier as well. Using double bubble insulation produces the maximum R-value.
The white on one side creates a nicer aesthetic if you will be installing it in an area that will be visible. It is also very easy to wash down should it be installed in a location that is exposed to dirt.
