Spraying in foam first introduced into the marketplace in the 1930’s, 1.7 – 2.8lb density urethane foam has an R-value of around 6.7 per inch, and would only require 3 1/4 inches (R-21) in the sidewalls of a home and 4 1/2 inches (R-32) in the ceilings. Its closed cells offer a built-in air barrier and will repel water, allowing it to be used to insulate and waterproof foundations in one application. With a class 1 fire rating, this product is commonly used in commercial roofing and insulation systems.

Closed Cell Spray Foam
Tiny closed cells within the polyurethane hold gases that are less thermally conductive than air. They are tightly packed, resulting in higher density and R-value.
Moisture to Mold
Homes without an air barrier have air leakage that transports moisture through walls that moist air gets into the walls and attics, condensing and promoting the growth of mildew and mold.
