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 homes with a tilt garage door lose a surprising amount of heat through that single, uninsulated surface. A typical metal tilt door has an R-value of R0.0, offering no resistance to heat or cold – like leaving a giant hole in your home’s thermal envelope.
Adding purpose-built tilt door insulation transforms a bare metal panel into an effective thermal barrier, improving comfort, lowering energy bills. For new home builds, it also helps achieve 7-Star NatHERS ratings under NCC 2022.
Tilt doors are popular in older and architect-designed Australian homes. Made from a single sheet of metal, they behave like a radiant heater in summer and a freezer panel in winter.
Without insulation:
Heat radiates through the thin metal and into the garage.
Cold air seeps in overnight, chilling adjoining rooms.
Condensation builds up inside the panel, leading to rust and corrosion.
A well-insulated tilt door reverses all of this — delivering year-round comfort and protecting your investment.
Unlike wall or roof products simply glued to a door, ThermaDoor Premium Tilt Door Insulation is engineered for garage doors. It’s cut to size, mechanically fixed, and designed to maintain a vital air cavity for enhanced thermal performance and condensation control.
Each ThermaDoor® panel features:
Laminated (not glued) construction for a premium, long-lasting finish.
Lightweight, water-resistant EPS core that won’t overload hinges or absorb moisture.
Australian-made materials compliant with AS/NZS 4859.1 and installed in alignment with AS 3999 best-practice methods.
ThermaDoor Premium isn’t a generic wall panel — it’s a tested garage door system. Independent engineering verification under AS/NZS 4859.2:2018 confirms a dual-season R-value of R1.48 (Winter) and R1.43 (Summer) for the complete assembly.
That means you’re getting real, measurable results, not theoretical numbers taken from unrelated applications, or worse still, made up numbers that are purely marketing spin.
Adding tilt door insulation with ThermaDoor can:
Significantly cut heat transfer through the door
Improve comfort in rooms adjoining or above the garage.
Reduce heating and cooling demand across the home.
Protect the door from rust and condensation.
Deliver a professional, finished interior appearance.

ThermaDoor Premium — purpose-built, tested to AS/NZS 4859.2, not wall insulation.
Yes — reduces heat transfer & helps achieve 7-Star NatHERS under NCC 2022.
Independent verification: R1.48 Winter / R1.43 Summer as a full system.
No – traps moisture, ruins air gap and thermal performance.
