Commercial spray foam insulation is widely utilized in the United States to enhance energy efficiency, air sealing, and moisture control in office buildings, warehouses, retail centers, and other commercial structures. This insulation method involves applying expanding polyurethane foam that adheres to surfaces, filling gaps, and forming a continuous barrier. It is effective in reducing heating and cooling costs, preventing air infiltration, and improving indoor environmental quality. Commercial spray foam insulation also contributes to soundproofing and structural support. Due to its durability and performance in varied climates, it is a preferred choice for new construction and retrofit projects across commercial sectors.
