The manufacturing costs of spray foam insulation are higher than those of other insulation products. The raw chemical materials are more expensive than recycled cellulose or glass fibers. Chemical processing facilities are more expensive to build and maintain, with stricter safety protocols and testing protocols.

Concrete has an R-value of between 0.1 and 0.2, but when combined with the built-in EPS foam, Fox Blocks boast an impressive R-value of 22. In addition to providing strong walls, ICF walls achieve such high R-values because of the different construction methods.

Spray foam is an ideal choice for insulating the floor of the attic because it is air impermeable and a powerful insulator. This will keep conditioned air in the living area of the home, and the warm or cool air in the attic from entering the home where it can cause condensation, mold and other problems.
