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 22.2) provide year-round comfort and improved energy efficiency. Smart, indeed.

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.
