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 Hobart or anywhere in Tasmania, 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.
Tasmania's winters are the harshest in mainland-adjacent Australia. Launceston regularly drops below 0°C overnight, and an uninsulated garage door bleeds warmth straight out of your home. ThermaDoor's EPS core and foil backing work together to slow heat loss and keep your garage usable through the coldest months, whether your door faces south, east, or straight into the morning frost.
Tasmania's high rainfall and humidity put pressure on garage environments in a way most mainland states never experience. 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 Tasmania throws at it, year after year.
Tasmania's summers can surprise you with warm, dry days — but temperatures plummet once the sun goes down. An uninsulated garage swings between extremes, putting stress on stored gear, vehicles, and anything temperature-sensitive. ThermaDoor stabilises the environment inside your garage, so your tools, equipment, and stored items stay protected from extreme fluctuations year-round.
With a stable, comfortable temperature year-round, Hobart and Tasmania 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.”

Absolutely. Tasmania has some of the most extreme temperature swings in Australia — hot, dry summers and genuinely cold winters with Antarctic air pushing up from the south. An uninsulated garage door acts like a giant heat sink in summer and a cold radiator in winter. ThermaDoor’s EPS panels significantly reduce that thermal transfer, making your garage more comfortable and reducing the load on any heating or cooling in adjacent rooms.
Yes. The ThermaDoor DIY kit is designed to be installed by a homeowner with basic tools in a few hours. No trades are required. Full instructions are included, and our support team is available if you need guidance during installation.
ThermaDoor is supplied and installed by authorised distributors across Tasmania. In Hobart, Independent Roller Doors and On The Mark Garage Doors are our certified installers. Contact them directly or use our contact form and we will connect you with the right installer for your area.
Yes. ThermaDoor is purpose-designed for both sectional (panel-lift) garage doors and tilt doors, which are common in older Tasmanian homes. If you are unsure which door type you have, contact us and we can help you identify the right kit.
ThermaDoor’s laminated vinyl finish is water resistant and does not absorb moisture — unlike polyester batts or open-cell foam products that can deteriorate in Tasmania’s high-rainfall, high-humidity conditions. The panels will not sag, rot, or harbour mould over time.
DIY kit pricing starts from $290 for a single door (8 panels) and $580 for a double door (16 panels), not including freight. Freight to Tasmania is calculated at checkout. For a professional installation quote, contact your nearest authorised installer.
Yes — particularly in homes where the garage is attached or shares a wall with a living area, which is very common in Hobart and Launceston. Customers consistently report that insulating the garage door reduces the temperature bleed into adjacent rooms, lowers heating and cooling costs, and makes the garage itself usable year-round rather than just in mild weather.
