Counting the Cost: What to Know About Closed Cell Spray Foam

Closed cell spray foam differs from open cell in both structure and performance. Its rigid form strengthens walls and reduces air movement. Because the foam hardens after application, it forms a vapor barrier and resists water absorption. That strength makes it popular for roofs, basements, and areas exposed to moisture. Its insulation value, or R-value, also exceeds many common alternatives. These qualities explain its growing use in both residential and commercial construction.
