1). How does Spray Foam work?
2). How does Spray Foam compare to fiberglass and cellulose insulation?
3). What’s the difference between open-cell and closed-cell Spray Foam?
Closed-cell Spray Foam is denser and has a higher R-value. The cells are closed and are packed tighter and it makes for an excellent insulator. It has an R-value of 5.8 to 7.0 per inch and qualifies as an air barrier at 1 inch, and a vapor barrier at 2 inches. It is air impermeable and moisture resistant which makes it extremely difficult for mold and mildew to grow.
