Single bubble insulation is a cost-effective way to keep your building cool in the summer and warm in the winter. Single bubble is an 1/8” thick single layer of bubble insulation primarily used in warm climates. We offer this in two different options, Foil/Foil and Foil/White. The first option has a foil surface on both sides, while the second option has foil on one side and white on the other. Both products are equal in performance and stop 96% of radiant heat. The main difference between the two is cosmetic.
