How does spray foam work as insulation?

Spray foam insulation forms a powerful, airtight barrier through a simple chemical process. First, two components are mixed and sprayed, causing rapid expansion that fills all gaps. This creates a solid seal, eliminating energy-draining air leaks. Its high R-value, especially in closed-cell foam, effectively blocks heat transfer, leading to stable indoor temperatures and lower bills. Additionally, closed-cell foam resists moisture, preventing mold and structural damage. Open-cell foam, due to its texture, dampens sound. Ultimately, spray foam enhances energy efficiency, comfort, and saves money.
