Intellicore Insulation Technology

Canyon Ridge Louver

Clopay® Intellicore® technology is a superior insulation for garage doors, offering homeowners increased benefits including enhanced strength and reduced heat transfer. By providing optimal insulation, it ensures a cozy and safe environment in your garage while reducing energy expenses. With its long-lasting durability and industry-leading R-values, it’s a reliable investment you can count on for years to come.

Polystyrene garage door insulation, typically installed on many traditional garage doors, are insulated with rigid panels of polystyrene sandwiched between steel layers or placed inside of your single-layer garage door, backed by vinyl.

However, we formulated Intellicore insulation with polyurethane to outperform doors containing polystyrene insulation. Our insulation technology is comprised of polyurethane form that we inject between the steel layers of the door. The polyurethane foam expands into the open space between the steel layers and bonds to door’s frame, insulating every inch of the garage door.

Garage doors with Intellicore technology will give you the optimal solution for your garage’s climate control, and is the best choice for homeowners that live in areas with extreme temperatures or varied seasons. No matter what you keep in your garage, you can trust that it’s safe from harsh temperatures when you install a garage door with Intellicore insulation technology.



Intellicore technology is made to provide our doors with dense and uniform insulation, as well as sound-absorbing properties.

To demonstrate the difference, we conducted tests and analyzed the sound-proofing abilities of our insulation against traditional polystyrene insulated garage doors. The results were impressive. Traditional garage doors produced sounds measuring 96 decibels, while Intellicore doors produced sounds measuring 80 decibels. Keep in mind that the decibel scale is logarithmic—not linear—so Intellicore insulated doors are actually three times quieter to the human ear.


To ensure the best consumer value, our Intellicore technology also reinforces our garage doors from the inside-out. After testing the durability of our insulated garage doors, they have been found to be twice as strong as generic polystyrene insulated doors with the same measured thickness. This increased durability provides you with a greater return on investment with better resistance to everyday wear and tear.
