For Garage Door Systems
ThermaDoor is designed and manufactured in Queensland, with our factory at Chevallum on the Sunshine Coast. When you order a ThermaDoor DIY kit for delivery to Melbourne or anywhere in Victoria, you are buying Australian made insulation from a business that has engineered its product specifically for the Australian climate — not an imported generic kit adapted for local conditions.
Melbourne's summers are unpredictable but the heat is real. Northerly winds push garage temperatures well past 50°C in an uninsulated space, and west-facing doors cop it hardest. ThermaDoor's EPS core and reflective foil backing work together to block radiant heat and keep the garage usable, whether your door faces north, west, or straight into the afternoon sun.
Victoria's weather swings are hard on uninsulated spaces. Summer heat, autumn rain, cold snaps and everything in between puts pressure on your garage environment year-round. ThermaDoor's laminated vinyl finish is water resistant and impact resistant, unlike open-cell foam, polyester batts, or fibreglass insulation that absorb moisture and deteriorate over time. Built to handle whatever Victoria throws at it.
Melbourne winters are genuinely cold, with overnight temperatures regularly dropping to single digits. ThermaDoor slows heat loss overnight, so stepping into your garage on a winter morning is not the shock to the system it used to be — and your stored gear, tools, and vehicles stay protected from the cold year-round.
With a stable, comfortable temperature year-round, Melbourne and Victoria homeowners are reclaiming their garages as usable living spaces.
Here is how ThermaDoor changes what you can do with your garage.
Train comfortably year-round — no more sweltering summers or chilly winters.
Quieter, more stable temperatures for better focus and lower energy bills.
A retreat that stays cool in summer and warm in winter for real downtime.
Consistent conditions that protect materials and make projects more enjoyable.
A safer, more comfortable space for children’s play – fewer drafts and hot/cold spots.
A calmer climate for pets, reducing heat stress in summer and chills in winter.
ThermaDoor has been on the Australian market since 2012 — and in that time, no other brand has matched what we offer:

Flame retardant, construction-grade expanded polystyrene foam is the primary insulator in every ThermaDoor panel. It slows conducted heat transfer through the door — keeping your garage significantly cooler in summer and warmer in winter, year after year.
Durable, flame retardant, UV-resistant vinyl facing protects the panel from Australia's harsh climate. It resists fading, cracking, and weathering — delivering a clean, professional finish that holds its appearance and structural integrity for the life of the door.
Bonded to the back of every panel, this construction-grade foil reflects radiant heat, acts as a Class 2 vapour barrier, and achieves Group 1 fire performance classification. It's the same foil used to wrap Australian homes — completing the three-layer system.

⭐⭐⭐⭐⭐
Karen and the crew were fantastic to deal with from start to finish. The product is amazing and has decreased the temperature in our garage by 10–15 degrees C and also decreased the temp in our house. It was super easy to self install. Massive thumbs up!”
⭐⭐⭐⭐⭐
“Our garage was very hot and a suggestion from a friend meant that we contact ThermaDoor. From the initial contact to the completion, the company was very professional. The product is very good and I would definitely get their team to install. Today Don arrived on time and got the job done very quickly. The addition of the door seals was a good decision as they remove any dust and breeze that used to come through the sides and top.”
⭐⭐⭐⭐⭐
“Garage temps have dropped 4–6°C since installation and so glad we installed the ThermaDoor panels. We built a new house in 2023/2024 and the garage door gets full western sun every afternoon. I made sure to take note of our garage temps before installation and noticed immediately after installation the temp dropped 4–6°C in summer and in winter it’s not as cold. I also noticed the noise is reduced.”
⭐⭐⭐⭐⭐
“Everything about ThermaDoor was fantastic. Easy online ordering, fast interstate delivery and DIY installation was straightforward and a breeze. I would recommend the business and the product.”
Ready to transform your garage?
Yes — and Melbourne’s climate is one of the strongest arguments for it. Summer northerlies push uninsulated garage temperatures past 50°C, while winter overnight lows regularly drop to single digits. ThermaDoor’s EPS core and reflective foil backing work in both directions, blocking radiant heat in summer and slowing heat loss in winter. The result is a garage that stays 10 to 15 degrees closer to ambient temperature year-round, which makes a measurable difference to both comfort and energy bills in a home with an attached garage.
Professional installation in Victoria is available through ThermaDoor’s authorised distributor network. Distributors are located in Shepparton, Pakenham, Geelong and Mildura. Contact us and we will connect you with your nearest authorised ThermaDoor installer. If you are in Melbourne metro or an area not covered by a local distributor, our DIY kit ships direct to your door and can be installed in a few hours without trades.
ThermaDoor DIY kits start from $290 for a standard single door (8 panels) and $580 for a double door (16 panels), delivered anywhere in Victoria. Professional installation pricing varies by distributor and door size — contact your nearest authorised ThermaDoor installer for a quote. Compared to the cost of running air conditioning to compensate for an uninsulated garage, most Melbourne homeowners recover the cost within the first summer.
Yes. ThermaDoor’s laminated vinyl finish is water resistant and impact resistant, which means it handles rain, humidity and temperature swings without absorbing moisture or deteriorating. Unlike fibreglass batts or open-cell foam products that can sag or absorb moisture over time, ThermaDoor panels are purpose-built to maintain performance through the full range of Victorian weather conditions.
