How much area does the kit cover?

Ten panels at 2 by 5 feet each cover about 100 square feet, enough for a standard one-car garage door. Measure your door first; a two-car door needs two kits.

Does it really lower garage heat?

The reflective surface blocks radiant heat, which helps most on a door that faces the sun. It does not add much insulating R-value, so expect a moderate drop, not a cooled garage.

Cut each panel to fit, then tape it to the inside of the door. Clean and dry the door first so the adhesive holds, and leave the door's hinges and tracks clear.

Will it fit my door's panels?

The 2 by 5 foot sheets are larger than most door sections, so you trim them to size. Cutting around hinges and struts takes time but needs no special tools.

Is $89.87 a good price?

Only one store lists it new at $89.87 as of November 4, 2026, so there is no lower price to compare. Similar 10-panel kits often sell for less, so check coverage and thickness before buying.
