Double bubble is not suitable for under concrete. Because of the air space built between the layers of foil, this bubble insulation works to keep radiant heat from penetrating a structure from the outside, and the radiant foil reflects interior heat back into a structure from the inside.
Foil-Double Bubble-Foil Insulation 4' x 25' s. While effective, this type of insulation does not casino night rochester minnesota the highest R-Value available and is susceptible to deterioration. If the load-bearing capacity of the roof substrate is in question, a tear-off also reduces the additional weight of a second roof. Thermal Design provides production rate estimates based upon the degree of difficulty. Foil-Double Bubble-Foil Insulation 4' x 75' s. Other techniques similar to overlayment, such as spray-applied foam products, may be viable alternatives.
