I see “Bubble Foil” in home improvement stores like Home Depot and Lowe’s – Is it better?
Bubble Foil is a good product and has many uses. The most common use is in metal buildings to prevent condensation. However, bubble foil insulation is often overused in residential attics. It does work, however it is the foil doing the work and not the bubbles in a ventilated attic. And, the bubble products cost a lot more. In addition, bubble foil products do not allow water vapor through often creating an unintended vapor barrier. Read about the difference between Radiant Barrier Foil and Bubble Foil Insulation here.
