Intellicore insulation technology
Warmer. Quieter. Stronger.

Commercial doors featuring Intellicore® insulation technology represent the ultimate smart choice. Clopay’s Intellicore® is a proprietary polyurethane foam that is injected into the door, expanding to fill the entire structure. The result is a door with incredible strength and durability. Its dense insulation also produces a quieter door, while its industry-leading R-values (p to 18.4) provide year-round comfort and improved energy efficiency.
