Garage door insulation kit helps reduce heat transfer to keep your garage cooler in summer and warmer in winter. This reflective insulation roll set uses a triple-layer build—aluminum foil radiant barrier, 6 mm EPE foam core, and white PE film moisture layer—for dependable thermal performance without adding heavy bulk. Cut-to-fit rolls make it easy to tailor panels to common 2-car garage door sizes for a cleaner, more comfortable workspace.

Upgrade your garage door with a reflective radiant barrier designed for quick cutting, clean lines, and practical durability. The aluminum foil surface reflects heat, the EPE foam core slows conduction, and the white PE film helps manage moisture—ideal for garages that swing from summer heat to winter cold. Use the included double-sided cloth tape, utility knife, and scraper to build a tighter, more controlled space for parking, storage, hobbies, or home projects.
