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 Perth or anywhere in WA, 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.
Built for Perth & Western Australia's Climate
Intense Summer Heat
Perth summers are famously relentless. Weeks of 35°C+ days turn metal garage doors into giant radiators, pushing garage temperatures well over 50°C. ThermaDoor's EPS core and reflective foil backing work together to block radiant heat, keeping your garage significantly cooler even when your door faces the harsh afternoon sun.
Coastal Conditions & The 'Freo Doctor'
While the afternoon sea breeze brings relief, your garage has usually spent the entire day baking. ThermaDoor's laminated vinyl finish not only brightens the space but is highly durable and easy to wipe clean. Unlike batts or open-cell foam that degrade over time, our panels maintain their structural integrity year after year in WA conditions.
Chilly Winter Mornings
Perth might be known for its heat, but winter mornings regularly drop into single digits. An uninsulated garage bleeds your home's warmth straight out the door. ThermaDoor slows heat loss overnight, so stepping into your garage on a July morning isn't a shock to the system, and your stored gear stays protected from extreme fluctuations.
Unlock the Potential of Your Garage
What Changes When You Insulate Your Garage Door
- Customers report up to a 20°C reduction in garage temperature (results vary depending on garage orientation and other factors)
- Noticeably reduces street noise and the sound of the door operating, particularly in garages connected directly to living areas
- The durable white vinyl laminate finish instantly brightens your garage and is easy to wipe clean
With a stable, comfortable temperature year-round, Perth and Western Australia 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.

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.

Garage Door Insulation Across Perth & Western Australia
Perth Northern Suburbs Service Area
Our northside team services all suburbs from the Swan River up to Yanchep, including Joondalup, Wanneroo, Hillarys, Duncraig, Clarkson, Balcatta, Morley, Scarborough, and surrounding areas. The northern corridor is one of Perth’s fastest-growing regions, with newer homes and large double garages that are particularly exposed to the intense summer heat — making garage door insulation one of the most effective upgrades a homeowner can make.
Perth Southern Suburbs Service Area
Our southside team covers all suburbs from the river down to Mandurah, including Fremantle, Cockburn, Rockingham, Melville, Canning Vale, Armadale, Baldivis, and the Peel region. The southern suburbs experience strong afternoon sun exposure and coastal humidity, both of which drive up garage temperatures and accelerate heat transfer into adjoining living areas — conditions that ThermaDoor is specifically engineered to address.
Perth Eastern Suburbs & Hills Service Area
We also service the eastern corridor and Perth Hills, including Midland, Ellenbrook, Swan Valley, Kalamunda, Mundaring, Forrestfield, and Victoria Park. The Hills and eastern suburbs experience some of Perth’s most extreme temperature swings — scorching summer days followed by genuinely cold winter nights — making year-round thermal performance critical for garages used as workshops, home gyms, or living extensions.
Perth Western Suburbs Service Area
Our team is ready to service the coastal strip and inner-west, including Cottesloe, Claremont, Subiaco, Nedlands, City Beach, Leederville, and East Fremantle. While the sea breeze keeps temperatures more moderate along the coast, the salt-laden air and high UV exposure in these suburbs can degrade unprotected garage door surfaces over time — ThermaDoor’s durable vinyl laminate finish adds a protective layer while delivering real thermal and acoustic benefits.
DIY kits ship to all Western Australian postcodes.

⭐⭐⭐⭐⭐
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.”

Get in touch today to arrange your installation.
Why should I insulate my garage door in Western Australia's climate?
Insulating your garage door creates a critical thermal barrier that regulates temperatures inside the garage. This is especially beneficial during WA’s intense summer heat, stopping your metal door from acting like a giant radiator. It also retains warmth during cooler southern winters, improving overall comfort and reducing energy transfer into adjoining living areas.
Can I install ThermaDoor insulation myself if I live outside Perth?
Absolutely. If you live in regional Western Australia or prefer to handle the installation yourself, our DIY garage door insulation kits are available for delivery statewide. The pre-cut panels are designed specifically for sectional and tilt doors, and a confident DIYer can complete a double door in an afternoon using our step-by-step video guides.
What makes ThermaDoor the best garage door insulation for WA homes?
ThermaDoor is Australia’s original, purpose-made garage door insulation — it is not repurposed wall or ceiling insulation. It features a high-density construction-grade EPS core, a laminated sisalation foil backing to block radiant heat, and a durable vinyl face. It delivers an independently calculated thermal value of R1.43 (winter) and R1.39 (summer) specifically within the garage door environment.
Will insulating my garage door reduce street noise?
Yes. In addition to thermal benefits, ThermaDoor insulation significantly reduces acoustic transfer. The 35mm high-density panels dampen the vibration of the metal door and provide a thick barrier against external noise, making it an ideal upgrade if you live on a busy Perth road or use your garage as a home office, gym, or playroom.
Is ThermaDoor insulation compliant with Australian building standards?
Yes. ThermaDoor is proudly Australian owned and manufactured. Our insulation panels are calculated to AS/NZS 4859.1 & 2:2018 standards and align with AS 3999 for insulation installation. Whether you are building a new home in Perth or retrofitting an existing garage, ThermaDoor supports 7-star NatHERS designs and meets the latest NCC 2022 energy compliance requirements.
