Garage door insulation

If you are among the many builders, designers or new home owners looking to achieve more energy efficiency throughout the homes you design or build, then consider ThermaDoor Garage Door Insulation as a whole-house approach to completing the insulation envelope around your home.

Proudly Australian owned and manufactured, ThermaDoor is a construction grade expanded polystyrene (EPS) panel, laminated with an impact resilient, easy to clean vinyl finish. ThermaDoor Garage Door Insulation has been specifically designed to fit inside the panel of your new or existing sectional garage door.

With a thermal value of R1.47, ThermaDoor Garage Door Insulation minimises the effects of our harsh Australian climate, by reducing heat loss and heat gain transferring through your metal sectional garage door. Installing ThermaDoor will result in better comfort and a better insulation system; a better value for today and an even better investment for tomorrow.
