For Garage Door Systems
Building to 7 stars? ThermaDoor is the only garage door insulation with the engineering documentation your energy assessor needs.
Purpose-Built. Independently Tested. Since 2012.
Hervey Bay’s salty coastal air and steamy subtropical afternoons can quickly turn your garage into a hot, sticky sauna. And when those unexpected cold snaps hit, the chill can creep through overnight. These temperature swings 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 Hervey Bay 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 in Hervey Bay and the wider Fraser 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 Hervey Bay 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 Hervey Bay's Climate
Coastal Heat & Summer Sun
Hervey Bay's summers are long and hot, with garage temperatures easily exceeding 40°C in an uninsulated space. ThermaDoor's EPS core and reflective foil backing work together to block radiant heat and keep the comfort in, whether your garage faces the bay or the western sun.
Storm Season Protection
The Wide Bay region's wet season brings heavy tropical downpours, strong winds, and wind-driven moisture. 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 Hervey Bay's mild winters, early mornings can be surprisingly cool. ThermaDoor slows heat loss overnight, so stepping into your garage in the morning isn't a shock to the system — and your stored gear stays protected year-round.
A Real Home. A Real Result.
Verified R-Values You Can Trust
Surface temperature readings: 37.6°C at the steel hinge (thermal bridge) / 32.6°C at the ThermaDoor panel
What you are seeing: The blue areas show ThermaDoor panels doing their job — blocking radiant heat. The red and orange areas are the steel hinges and panel joins conducting heat straight through the door. This is thermal bridging, and it happens in every sectional garage door. It is why material R-values alone do not tell the full story — and why ThermaDoor’s R-values are calculated on the complete installed door assembly, steel and all.
Calculated on the Complete Installed Door – Not Just the Insulation Material
In Hervey Bay, the difference between a material R-value and a tested door assembly R-value is the difference between a product that looks good on paper and one that actually keeps your garage cooler. ThermaDoor’s R1.43 is tested on a complete installed door — steel, hinges, and all.
Our article on thermal bridging and garage doors explains why tested assembly values matter.

Posted on Google Caroline nTrustindex verifies that the original source of the review is Google. We purchased a DIY kit for our garage door to cool it down before installing a solar battery. We are really impressed with the results and have noticed a significant difference in the temperature since adding the insulation. Very glad we did it!
Owner's reply
Thank you so much, Caroline, this is exactly why we do what we do! 🙌 Preparing the garage for a solar battery is one of the smartest reasons to insulate first, and you've nailed the order of operations. Our customers regularly report temperature reductions of up to 20°C. A cooler garage isn't just more comfortable it's a better environment for battery storage. Most solar battery manufacturers specify an optimal operating temperature range, and an uninsulated steel garage door in an Australian summer can push well outside that range. You've protected your investment before it even arrived. Very glad we could be part of that.Posted on Google Shane WTrustindex verifies that the original source of the review is Google. Thermadoor's garage door insulation is the best. I have tried others and they dont even come close. Thermadoor is easy to install and the panel looks great. It looks very professional and not like an after thought. I cannot recommend this product enpugh. You will not be disappointed if you choose to go with Thermadoor insulation. Photos to come
Owner's reply
Thank you, Shane — "they don't even come close" is high praise and we genuinely appreciate you taking the time to share that. You've touched on something we hear a lot... ThermaDoor looks like it belongs on the door, not like something that was added as an afterthought. That comes down to the factory-laminated vinyl face and the mechanical fix system, which keeps everything flush and tight. It's designed to look like part of the door because it essentially becomes part of the door. We also love receiving photos from our customers and we're looking forward to seeing yours when they're ready! 📸Posted on Google Deborah RTrustindex verifies that the original source of the review is Google. I cannot speak highly enough of ThermaDoor and the product they have created. It is quite simply second to none. We had ThermaDoor installed on our new 16 panel, fully west facing garage door, and the result has exceeded anything I could have hoped for. The temperature in the space has now dropped by at least 20 degrees, which has completely transformed how we can use it. Our garage is not just a garage , it’s “the Cave” for my son, who is an NDIS participant, and his support team. We had already invested in an epoxy floor and replastering the space, but despite that, the heat made it almost unusable. Since installing ThermaDoor, it has become a comfortable, functional, and genuinely enjoyable environment. It has opened up a whole new level of independence and capacity building for my son and his team. The product itself looks premium, fits beautifully, and has made the space noticeably quieter as well , something I didn’t expect but absolutely love. Another positive for me is that the core product Is aesthetically pleasing with a beautiful vinyl panelling covering that finishes the door to a higher standard, Another 5 ⭐️ stand out of a quality solution. And then there is the service. Peter and Karen were nothing short of exceptional — knowledgeable, responsive, and genuinely invested in helping us achieve the best outcome for our son to make his space a home away from home! This has been one of the most impactful upgrades we’ve made to our home, and I know it will carry us just as beautifully through winter as it has through summer. I am so grateful, thank you for helping us create a space that truly supports my son’s world and capacity building Deb4Sammy Mountain Creek
Owner's reply
Deb, thank you, this means so much to us. We are genuinely honoured to have played a part in creating a space that works for your son and his support team. "The Cave" is exactly what a space like this should be... comfortable, functional, and truly his own. The fact that a 20°C temperature drop has opened up a whole new level of independence and capacity building is everything we could hope to hear. We are so glad they could be part of your family's story. Thank you for trusting us with it. Peter & Karen🙏Posted on Google 81micmicTrustindex verifies that the original source of the review is Google. Everything about ThermaDoor was fantastic. Easy online ordering, fast interstate delivery and DIY installation was straight forward and a breeze. I would recommend the business and the product.
Owner's reply
We believe happy customers are the best outcome we can achieve. Thank you for sharing your experience, we really appreciate you taking the time to let others know. Peter & KarenPosted on Google Paul BTrustindex verifies that the original source of the review is Google. 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. The door closer mechanism was modified to close with the extra panels and it is much quieter. I would recommend this company for the great job at a very reasonable price.
Owner's reply
Thank you, Paul we are really glad Don could get the job done efficiently and that the whole experience from first contact through to installation met the mark. The door seals are an often underestimated part of the system. Once people experience the difference in dust, draughts, pests and noise they wonder how they managed without them. The spring and closer adjustment is something we always include as part of a professional install, so it's great to hear that came through in the result. Thanks again for the kind words and for the recommendation. Peter & Karen🙌Posted on Google Lorraine LTrustindex verifies that the original source of the review is Google. Short review: Garage temps have dropped 4c to 6c since installation and so glad we installed the ThermaDoor panels. Long review: We built a new house in 2023/2024 and the garage door gets full western sun every afternoon plus we also have side glass doors on the garage for side access so it also gets lots of sun and heat. I made sure to take note of our garage temps before installation and noticed immediately after installation the temp dropped 4c to 6c in summer and in winter its not as cold and I also noticed the noise is less, so straight away money well spent. The garage just feels more comfortable on very hot days and you really notice the difference when you open the garage door and walk out into the front yard. The install guys were really nice and local for us (Sydney) and after panel installation they also serviced our garage door to make sure everything was OK and I appreciated their extra care and clean up afterwards. Installation didnt take long and the garage door looks great, you wouldnt know it was there unless I pointed it out to you. Well worth the investment in insulating our garage door and Ive recommended them quite a few times since. Edit. We installed the Premium panels
Owner's reply
Thank you for your kind words Lorraine. We are so glad ThermaDoor Premium has made a difference in your circumstances!Posted on Google David DTrustindex verifies that the original source of the review is Google. 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 instal. Massive thumbs up!
Owner's reply
Thanks so much for your review David. We’re so glad ThermaDoor Premium met your expectations!Posted on Google Paul VTrustindex verifies that the original source of the review is Google. Big thanks to Karen & the team, great people to deal with. Panels have been in over 2 years and work great. Huge reduction in heat within garage, great product.
Owner's reply
Thank you, Paul. Two years in and still working great is exactly what we build them for. Karen will love seeing this! 😊 Longevity is something we're proud of — the factory-laminated construction holds up to the daily movement and Australian conditions in a way that glued or retrofit solutions simply don't over time. Really appreciate you coming back to leave a review.

I had my west facing garage door insulated and sealing brushes added to stop dust, some of the best money I have ever spent on a house improvement. Great service, efficient and reasonably priced. I would recommend in a flash.
Peta W
We’re super impressed with our newly-installed Thermadoor insulation, it works a treat on our north-facing garage door and looks very sharp. Top marks for customer service and Caleb’s very neat and tidy job on the install. Highly recommend this outfit
Justin H

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.

6.8 → 7.2 Stars
Independent NatHERS Modelling | Hervey Bay Climate Zone 10 | ThermaDoor Installed
Struggling to Hit 7 Stars? Your Garage Door Might Be the Answer
How Garage Door Insulation Helps Hervey Bay New Builds Meet NCC Requirements
If you are building a new home in Queensland, you already know about the 7-star NatHERS energy efficiency requirements under NCC 2022. Hitting that target can be difficult and expensive -- upgraded glazing, extra roof insulation, costly design changes.
Many homeowners and their builders overlook the largest moving part of the house: the garage door.
Independent energy modelling on a standard slab-on-ground home in Hervey Bay (Climate Zone 10) showed that insulating an unconditioned garage with ThermaDoor garage door insulation improved the home's NatHERS rating from 6.8 stars to a compliant 7.2 stars. That is a +0.4 star improvement from a single, low-cost upgrade. If your garage is air-conditioned, the improvement jumps to +1.4 stars.
To count in your NatHERS assessment, your energy assessor needs a verified assembly R-value -- not a material R-value or an unverified claim. ThermaDoor provides an independently verified R1.43 winter assembly R-value, calculated to AS/NZS 4859.2:2018 by a registered professional engineer. That is the exact number your assessor inputs into their NatHERS software.
Your next steps are simple:
1. Tell your builder you want ThermaDoor specified in your new build.
2. Send your energy assessor the link below -- it has the verified R-value report and full NatHERS compliance data they need.

Frequently Asked Questions - Garage Door Insulation Hervey Bay
How is ThermaDoor garage door insulation priced in Hervey Bay?
There are three ways to get ThermaDoor in Hervey Bay, each with different pricing. DIY panel pricing is shown in the table above — order directly from our online shop and install it yourself. If you’d prefer professional installation direct through ThermaDoor, pricing depends on a number of variables including door size, configuration, and travel — contact us directly and we’ll provide a quote specific to your job. Professional installation includes a spring balance adjustment to account for the added weight of the panels. Alternatively, our three local authorised distributors — Show It Off Home Improvements, SD Garage Doors, and Good Look Garage Doors — each set their own labour rates independently, so contact them directly for a supply and install quote. All options use the same genuine ThermaDoor product.
Will garage door insulation actually keep my garage cooler in Hervey Bay's heat?
Yes — and the results in coastal Queensland climates are significant. ThermaDoor’s tri-layer system (35mm EPS core, sisalation foil backing, and laminated vinyl facing) blocks radiant heat, reduces conductive heat transfer, and reflects solar energy away from the door surface. Our customers regularly report temperature reductions of 8°C to 15°C inside an insulated garage compared to an uninsulated one. ThermaDoor is independently tested to R1.43 (winter) and R1.39 (summer) — values calculated specifically for the garage door, not repurposed from wall or ceiling testing.
Is ThermaDoor suitable for Hervey Bay's coastal conditions — salt air, humidity, and storm season?
ThermaDoor is specifically designed for Australian coastal conditions. The laminated vinyl facing is water resistant and impact resistant, so it handles wind-driven rain and coastal moisture without absorbing water or degrading over time. Unlike open-cell foam, polyester batts, or fibreglass insulation, ThermaDoor will not sag, rot, or lose performance when exposed to humidity or the occasional storm. The EPS core is also mould and mildew resistant — an important consideration in Hervey Bay’s warm, humid climate.
Can I install ThermaDoor myself, or do I need a professional in Hervey Bay?
Both options are available. The DIY kit is designed for a standard homeowner with basic tools — no special skills required. Most single garage doors take 2 to 3 hours to complete, and double doors typically take 3 to 5 hours. Full step-by-step video guides are available on our website. If you prefer professional installation, Hervey Bay has three authorised ThermaDoor distributors — Show It Off Home Improvements, SD Garage Doors, and Good Look Garage Doors — who can supply and install for you. ThermaDoor also installs directly for customers who contact us.
Does ThermaDoor meet NCC 2022 energy compliance requirements for new builds in Hervey Bay?
Yes. ThermaDoor’s R-values are calculated to AS/NZS 4859.1 & 2:2018 and are backed by engineering reports specific to the garage door assembly — not generic wall or ceiling values. This makes ThermaDoor suitable for inclusion in NatHERS energy assessments and NCC 2022 compliance documentation. If you are building or renovating and need documentation for your energy assessor, contact us directly and we can provide the relevant technical data sheets and engineering reports.
What warranty does ThermaDoor offer, and does it cover Hervey Bay's climate conditions?
ThermaDoor carries a lifetime warranty on the EPS insulation core — it is guaranteed for as long as your garage door remains in service. The laminated vinyl finish and fixings are covered by a separate 7-year workmanship and materials warranty. Both warranties are designed with Australian conditions in mind, including coastal humidity, UV exposure, and temperature extremes. There are no hidden caveats related to climate zone — the warranty applies equally to Hervey Bay homes as it does across the rest of Australia.
