Made In Australia
Why Choose ThermaDoor?
ThermaDoor is a premium range garage door insulation, invented and manufactured by an Aussie builder specifically for the harsh Australian climate. It is the ONLY PURPOSE MADE garage door insulation available on the Australian market. Our ‘Premium Range’ offers:
Durability
Your garage door is a constant moving part. Insulation installed into your door is susceptible to deterioration whether it be pets scratching it, rodents eating it or just getting knocked around by everyday living. ThermaDoor garage door insulation is a construction grade 35mm thick, flame-retardant polystyrene core. The face of our panel is laminated with a durable, easy-clean white vinyl face that adds protection, and looks great too!
Additional thermal protection
The back of the panel is laminated with a builder’s grade sisalation foil – the same foil that most homes are wrapped with for your thermal protection. This foil backing faces the garage door, providing additional thermal protection to your garage space. Some customers have reported up to a 15-degree internal air temperature difference in their garage.
Energy efficiency
ThermaDoor garage door insulation helps maintain a stable internal temperature in your home during winter and summer, enhancing energy efficiency and potentially reducing costs. According to the Australian Government’s YourHome Website, a well-insulated home may cut cooling and heating bills by up to half. With a tested thermal value of R1.48, ThermaDoor garage door insulation minimizes the effects of our harsh Australian climate, by reducing heat loss and heat gain transferring through your sectional garage door.
Noise reduction
ThermaDoor garage door insulation adds an additional layer of thickness to your garage door, reducing sound transfer in and out of your garage. Our customers often also report that the door itself is much quieter after installation.
Increased comfort
ThermaDoor garage door insulation creates a more stable, constant temperature, making a more comfortable environment to utilise this space all year round.
Light weight
ThermaDoor garage door insulation adds approximately 7 – 8 kg of weight to a standard double garage door. This additional weight is easily accommodated by adjusting the springs after installation.
Fire resistant
ThermaDoor garage door insulation is made with a flame-retardant polystyrene panel. This means our panel will self-extinguish if exposed to a flame.
