Frequently Asked Questions

KoolDoor lines the inside of your existing garage door with closed-cell PIR foam panels. A bare metal door soaks up the sun and pushes heat straight into the room. The panels add an insulating barrier that slows that heat transfer, so the garage stays cooler in summer and warmer in winter.

In our testing, an insulated door keeps the space up to 20°C cooler on a hot day. The exact result depends on your climate, how the garage is built and how much sun the door gets.

KoolDoor suits most standard sectional and roller garage doors. You cut the panels to fit your door sections and press them in. If your door is in poor condition or an unusual shape, contact us first and we will help you check before you buy.

The panels are closed-cell PIR foam with a matte white finish on both sides. They carry an R1.5 rating, which measures how hard the material works to slow heat transfer.

Yes. We make side brush seals that block draughts, dust and pests around the edges of the door. They pair well with the insulation panels.

Every insulation kit comes with a 10-year guarantee against manufacturing defects. Seal kits are not covered by that guarantee, and installation labour is not covered either, but your Australian Consumer Law rights apply to both. See our warranty page for full details.
