What are the Differences Between Open and Closed Cell Spray Foam Insulation?
- 1. WHAT ARE THE DIFFERENCES BETWEEN OPEN AND CLOSED CELL SPRAY FOAM INSULATION?
- 2. LEARN ABOUT THE BIG DIFFERENCES BETWEEN OPEN AND CLOSED CELL SPRAY FOAM BEFORE DECIDING WHICH ONE TO HAVE INSTALLED.
- 3. CLOSED-CELL FOAMS are made up of trapped gas bubbles that are formed as the foam expands and cures.
- 4. The blowing agent in open-cell foams is released into the atmosphere when it expands and cures.
- 5. In closed-cell spray foam, the trapped gas increases the cured foam's insulation capability.
- 6. OPEN-CELL FOAM typically has R-values of 3.5-4.0, whereas closed-cell foam has R-values of 6.0-6.5.
- 7. Open-cell spray foam is best for structures where space is not limited, such as a crawl space or attic.
- 8. Closed-cell spray foam is best for getting high R-values in shallow areas of a structure.
- 9. The R-values of closed-cell foam tend to change overtime
- 10. If you are on a tighter budget then closed-cell foam would be your best option.
- 11. Open-cell foam is vapor semi-permeable and closed-cell foam is vapor semi-impermeable.
- 12. Closed-cell spray foam is the best option for preventing liquid water from getting into a structure.
- 13. Closed-cell foams are much denser and more common than open-cell foams.
