Warmer. Quieter. Stronger. 

intellicoretechIntellicore Cutaway Commercial DoorCommercial Overhead doors featuring Intellicore® insulation technology represent the ultimate smart choice for building owners. Clopay’s Intellicore is a proprietary polyurethane foam that is injected into a 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 (up to 27.2) provide year-round comfort and improved energy efficiency. Smart, indeed.

warmerIntellicorebadgeIntellicore-equipped doors have some of the highest R-values in the industry, up to 27.2. In cold climates, Intellicore helps keep your building or warehouse warmer. Alternatively, in hot climates, it helps keep the warm air out. At its core, a Clopay door with Intellicore is energy efficient, making your building more comfortable all year long. 


quieter Intellicore badgeIntellicore-equipped doors are simply quieter. Just shake a non-insulated door and then an Intellicore door and you’ll hear a big difference in noise levels. This means that common occurrences, such as a exterior traffic or wind hitting the door, will be uncommonly quiet with an Intellicore door.


stronger Intellicore badgeScientific tests show that a Clopay overhead door sections featuring Intellicore insulation are nearly twice as strong as a polystyrene door section of the same thickness. This enhanced rigidity provides greater resistance to everyday wear and tear. Essentially, a Clopay door with Intellicore will look better, longer.
