On the Sunshine Coast, humid afternoons and salty sea breezes can turn your garage into a sauna. Cool Hinterland nights and sudden southerly changes mean temperatures can swing dramatically after dark. From Caloundra to Noosa and into the Hinterland, these shifts affect more than just the garage. They impact the comfort of nearby rooms, drive up your energy bills, and cut off a valuable part of your home year-round.
ThermaDoor garage door insulation is purpose-built for the Sunshine Coast climate. Our premium EPS panels are engineered specifically for sectional and tilt doors to block up to 90% of radiant heat, reduce street noise, and instantly upgrade your garage with a durable, wipe-clean vinyl finish.
Proudly Australian owned and manufactured, we offer two simple ways to get ThermaDoor on the Sunshine Coast: order a DIY kit delivered directly to your door, or book a professional installation with our certified local technicians.
Learn how to keep your Sunshine Coast garage cool this summer without air-con.
Locally Based. Australian Made.
ThermaDoor is headquartered on the Sunshine Coast, with our factory at Chevallum. When you buy ThermaDoor, you’re buying Australian made insulation from a local business that knows the Queensland climate firsthand.
Built for the Sunshine Coast Climate
Tropical Heat & Humidity
Sunshine Coast temps regularly exceed 30°C with high humidity that turns an uninsulated garage into a sauna. ThermaDoor's EPS core and reflective foil backing work together to keep the heat out and the comfort in.
Storm Season Protection
ThermaDoor's laminated vinyl finish is water resistant and impact resistant — unlike open-cell foam, polyester batts, or fibreglass insulation that absorb moisture and fail in wet conditions. Built for Queensland weather.
Cool Winter Mornings
Even in the subtropics, Hinterland nights and winter mornings can bite. ThermaDoor slows heat loss overnight, so stepping into your garage in the morning isn't a shock to the system.
The Original. Still the Only.
ThermaDoor has been on the Australian market since 2012 — and in that time, no other brand has matched what we offer:
- The original and still the only purpose-made garage door insulation on the Australian market.
- Proudly designed, owned and manufactured right here in Australia by an Aussie builder.
- Designed specifically for sectional garage doors and tilt garage doors.

Three Layers. Engineered as One
High-Density EPS Core
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.
UV-Stable Vinyl Facing
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.
Sisalation Foil Backing
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.

⭐⭐⭐⭐⭐
David Dee
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!”
⭐⭐⭐⭐⭐
Paul Bonner
“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.”
⭐⭐⭐⭐⭐
Lorraine Lazzar
“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.”

Frequently Asked Questions - Garage Door Insulation Sunshine Coast
How much does garage door insulation cost
Typical supply and install range: $910 – $1200 for a double door. ThermaDoor (verified R1.43, vinyl face, sisalation foil back) lands at the top end of that bracket because its purpose made, includes mechanical fixing (not glued in) and spring adjustment.
Typical DIY range: $580 – $870 for a double door. Price estimate does not include freight.
Why is garage door insulation important on the Sunshine Coast
The Sunshine Coast experiences high humidity, salty air, and hot summers that can turn garages into ovens. Insulating your garage door with ThermaDoor helps block radiant heat, reduces temperature fluctuations and helps keep adjoining rooms more comfortable – especially during Queensland’s sweltering days.
Can I DIY, or do I need a pro - and how long does it take?
A confident DIYer can finish a double sectional door in about 3 hours using ThermaDoor’s pre-cut kit. Prefer a pro job? Our authorised garage door pros supply, fit and spring balance in around 2 hours – depending on the job.
Will ThermaDoor insulation hold up in coastal conditions of the Sunshine Coast?
Yes. ThermaDoor is purpose built for Australian homes and performs exceptionally well in coastal climates. The durable vinyl laminated surface resists moisture and salt air and provides further protection to the construction grade EPS core – it won’t degrade or become waterlogged over time due to humid environments.
Is ThermaDoor made in Australia?
Yes — ThermaDoor is proudly Australian made garage door insulation. Our business is headquartered on the Sunshine Coast at Chevallum, Queensland, and every ThermaDoor panel is manufactured in Australia to our own registered design — protected under the Designs Act 2003 (Cth). ThermaDoor is the only purpose-made garage door insulation designed and produced in Australia — not a repurposed wall or ceiling product adapted for garage doors. When you buy ThermaDoor garage door insulation on the Sunshine Coast, you’re supporting a local business and getting a product built specifically for Australian conditions, Australian door sizes, and Australian building standards.
What garage door types does ThermaDoor fit — sectional and tilt?
Yes — ThermaDoor is designed to fit both sectional garage doors and tilt garage doors. Each panel is custom-cut to suit the specific dimensions of your door, whether it’s a single or double door, sectional panel or tilt slab. The mechanical fixing system — no glue, no adhesive tape — works with both door types and is designed to stay securely in place as the door operates over thousands of cycles. If you’re unsure which door type you have or how many panels you need, our team can help you measure up before you order. Use our online measurement guide or contact us directly for advice specific to your Sunshine Coast home.
