About Double Bubble Foil Insulation
Double bubble foil insulation provides an effective vapor barrier and also provides superior protection against radiant heat transfer. Curious about double bubble foil insulation R value? Double bubble foil insulation works by reflecting heat instead of slowing it down and therefore the r value is determined by your assembly. Learn more about R-values
Double Bubble Foil Insulation Installation
Double Bubble Foil Insulation is commonly used in commercial applications as a vapor and condensation barrier in metal and post frame buildings. It has an R-value so it also has a thermal insulation value. You can install the double bubble reflective insulation during new construction or you can use the retrofit application for existing buildings.
Double Bubble Foil Insulation is also commonly used for roof insulation in commercial applications such as metal and post frame buildings and provides a vapor and condensation barrier. It can either be placed on the outside of the roof purlins during new construction or attached to the inside of the purlins in a retrofit application.
There are also many residential uses for Double Bubble Foil Insulation including:
