About this item
- SINGLE DOOR COVERAGE (8ft x 8ft): Designed to insulate one standard single garage door. For double-wide or two-car garage doors, purchase two kits for full coverage.
- Kit Comes with 8 Pre-cut Panels: Each panel measures 24"x48" and includes 48 one-inch square adhesive pads. Each panel is 5/32 inch thick and has reflective film on both sides, with 2 layers of bubble between the layers.
- Radiant Heat Control: Reflective air insulation reduces radiant heat transfer for more consistent garage temperatures. Durable in extreme conditions, engineered to perform in high heat and humidity while maintaining insulation integrity over time.
- Complete Do-it-yourself Kit: Installation requires no special tools. Panels can be trimmed with scissors or a box knife. Make sure door surfaces are free of dirt, moisture, and oil before applying the adhesive squares.
- High-temperature Adhesive Pads: Open-cell polyurethane foam pads are 1/8 inch thick with double-sided acrylic adhesive that conforms to multiple surfaces for secure attachment.
