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.

Rigid foam is the clear winner if you're looking for the highest R-value home insulation you can get. With an R-value of R-4 to R-6.5 per inch of thickness, it's ideal for insulating exterior walls, including basement walls.

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 insulation is a good option for Florida homes because it can cover all areas of your attic, no matter how oddly shaped the infrastructure is. Covering every crack creates a moisture-proof barrier that will keep the elements out of your home.
