Peter is a licensed builder with over 45 years of experience in the construction industry. In 2012, his expertise in energy efficient construction inspired the invention of ThermaDoor Premium garage door insulation - the original purpose made garage door insulation in Australia.
If your garage feels like an oven in summer and a freezer in winter, you’re not imagining it. Standard metal garage doors offer little to no thermal protection. That’s where ThermaDoor Premium garage door insulation Australia comes in.
Developed by licensed builder, Peter Hinton, ThermaDoor was born from a simple but powerful insight: A well-insulated garage can change the way your whole home feels. With over four decades of experience in residential construction, Peter saw firsthand how uncomfortable garages were impacting Australian homes, and set out to design a smarter, purpose-built solution.
So, is it worth adding insulation to your garage door? Let’s break it down.
Absolutely – and not just in theory.
ThermaDoor Premium is made for one job: improving comfort and energy efficiency by insulating garage doors. Our panels are designed using high density, construction grade expanded polystyrene (EPS), backed with construction grade laminated sisalation foil for radiant heat reflection, and finished with a durable vinyl laminated that’s impact resistant and easy to clean.
That’s a real, modelled R-value – not a guess based on wall or roof applications like many other products on the market!
Yes – especially with a properly installed, purpose-built system like ThermaDoor Premium
A non-insulated metal garage door acts like a thermal bridge, letting cold air in and drawing warm air out. In winter, this can significantly cool the adjacent rooms in your home. This is particularly relevant in Australian states such as Victoria and Tasmania that can experience extremely cold and unpredictable weather conditions.
Importantly, ThermaDoor includes a built-in air cavity, which adds an extra layer of insulation by preventing direct contact between the panel and the metal door. This cavity also reduces moisture build-up and potential condensation damage – something overlooked by glue-on system that violate best building practices.
The answer is a clear yes.
Many customers ask, “Can I just use wall or ceiling insulation on my garage door?” Here’s the truth: Most products on the market were never meant for garage doors. Whether it’s PIR boards, polyester batts or acoustic panels, they may claim high R-values – but when misapplied, they can absorb water, add dangerous weight and reduce performance due to improper installation.
ThermaDoor Premium is different. It’s not repurposed wall insulation. It’s designed for sectional and tilt garage doors and has been independently test for this exact purpose. And it’s been trusted by thousands of homeowners, builders and garage door industry professionals across Australia for over a decade.
Yes. And the difference is not just thermal. It’s also:
Uninsulated garage doors can also compromise your 7-star energy rating if you’re building under NCC 2022. ThermaDoor’s tested R-values can be included in NatHERS simulations, providing a cost-effective support to compliance – often for less than $1,000!
Whether you’re upgrading your existing home or working on a new build, ThermaDoor garage door insulation is a smart investment in year-round comfort, energy savings and future ready compliance.
