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.
Most Australian homeowners think about insulating their walls, ceilings, and windows. But few realise that their garage door has an R-value of zero (R0.0) – meaning it provides no resistance to heat or cold transfer. With garage doors often making up to a third of a home’s façade, leaving this gap uninsulated is like leaving a giant window wide open all year.
The result? Hot garages in summer, freezing spaces in winter, and higher energy bills as your air conditioner or heater works overtime.
That’s where garage door insulation comes in – but not all products are created equal.
ThermaDoor Premium isn’t just another panel cut to size and glued on. It’s Australia’s original, and still the only purpose-built garage door insulation, designed and engineered for sectional and tilt garage doors. Since 2012, ThermaDoor has set the benchmark for performance, compliance, and durability.
Over the years, others have tried to imitate, but here’s what sets it apart:
ThermaDoor Premium has dual-season R-values of R1.48 (winter) / R1.43 (summer).
Verified under AS/NZS 4859.1 & 4859.2, the official, most stringent and up to date Australian standards for insulation and backed by formal thermal engineering reports that we are happy to provide to our customers.
Some companies selling products off as garage door insulation often quote R-values from wall or ceiling applications or ‘standalone’ (not garage doors), which is misleading. Worse still, some quite high R-values that are nothing more than an uninformed guess.
Professionally installed to AS 3999 standards, ensuring safe fixing, preserved air gaps, and correct spring adjustment as per AS 4505.
Unlike products that are glued directly to the metal (destroying thermal performance and voiding warranties), ThermaDoor maintains an air cavity for optimal results.
Some products marketed as “garage door insulation” are really just repurposed materials:
PIR foam boards – Originally made for wall and car park insulation. They’re heavy, not engineered for garage doors and quote R-values not supported by evidence relevant to garage doors.
Plain graphite polystyrene sheets – Cheap to produce, sometimes dressed up as premium. Don’t get caught paying premium price for a budget product!
By contrast, ThermaDoor® Premium was designed from the ground up for garage doors. Its laminated vinyl finish gives long-lasting durability, a professional appearance, and performance you can rely on – supported by thermal engineering reports.
Proudly Australian-made.
Designed by licensed builder Peter Hinton, with 45+ years of construction expertise.
Protected by design registration — it’s the real deal, not a copycat.
Lower Energy Bills – Reduce heating and cooling loads.
More Comfortable Spaces – Garages become usable as gyms, workshops, or media rooms.
Quieter Homes – Insulation dampens traffic and street noise.
Durability – Pet-proof, water-resistant, and long-lasting.
For new home builds – Helps achieve 7-Star NatHERS ratings under NCC 2022, often for less than $1,000.
ThermaDoor is available as:
DIY Kits – Easy to install yourself with step-by-step instructions.
Professional Installation – Fully compliant, including spring adjustment and warranty protection.
This flexibility means there’s a solution for every homeowner and every budget.
If you’re serious about insulating your garage door, ThermaDoor Premium is the only option purpose-built for Australian homes.
While others rely on wall insulation panels, overinflated marketing claims, or shortcuts that risk damaging your garage door, ThermaDoor offers:
✅ Verified R-values
✅ Full compliance with Australian Standards
✅ Purpose-built durability
✅ Proven performance since 2012
Insulate Smart. Live Better.
Choose ThermaDoor® Premium – the original and still the best garage door insulation in Australia.
ThermaDoor® Premium is the only purpose-built garage door insulation engineered specifically for sectional and tilt doors in Australian homes. Unlike products that repurpose wall or car-park insulation, ThermaDoor is tested and verified under AS/NZS 4859.1 & 4859.2, delivering genuine dual-season R-values (R1.48 winter / R1.43 summer). It’s Australian-made, compliant with AS 3999 installation standards, and designed by a licensed builder to provide superior comfort, energy efficiency, and long-term durability.
An uninsulated garage door has an R-value of zero (R0.0), meaning it lets heat and cold flow straight through. Installing ThermaDoor® Premium garage door insulation can dramatically improve comfort by reducing heat gain in summer and heat loss in winter. Homeowners typically notice lower energy bills, quieter indoor spaces, and more usable garages – whether for a home gym, workshop, or kids’ play area.
Yes. ThermaDoor® Premium complies with both AS/NZS 4859.1 & 4859.2 (material performance) and AS 3999 (installation method). When professionally installed, it also meets AS/NZS 4505 garage door safety requirements — ensuring correct spring adjustment and preserving manufacturer warranties. Few competitors can claim the same level of verified compliance and documentation.
ThermaDoor® offers both DIY garage door insulation kits and professional installation services. The DIY kits include precision-cut panels and clear step-by-step instructions. For homeowners wanting full compliance with AS 3999 and spring adjustment by a qualified installer, the professional option provides peace of mind and warranty protection. Either way, you get the same high-quality, Australian-made insulation panels.
