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.
Lately, almost every company selling products as garage door insulation in Australia has started marketing their products as premium. But when every product is called premium, the word loses its meaning.
In reality “premium” should not be just a label, it should describe a product that is superior in design, tested to Australian Standards, built for purpose, and proven to deliver long-lasting performance.
Unfortunately, many companies use premium as a marketing badge while selling materials that were never designed for garage doors in the first place.
ThermaDoor sells these plain polystyrene products as our budget Plain range. They work acceptably if you are happy with a better than bare metal outcome. Unfortunately, some brands are repackaging this standard polystyrene or graphite polystyrene as “premium garage door insulation”. But this is the same product used in walls, floors and ceilings – not engineered specifically for garage doors – that’s why we sell these as a budget range.
Don’t get caught paying a premium price for a budget product.

Because “premium” is often used as a marketing label rather than a technical standard. Many companies use it to make basic polystyrene or wall insulation panels sound more advance than they really area.
Premium garage door insulation should be purpose-made for garage doors, tested under AS/NZS 4859.1 & 2:2018. It must provide verified R-values, be durable, moisture resistant, and lightweight enough not to damage the garage door or impede its functioning.
No. While these materials have uses in packaging, walls, or soundproofing, they are not designed for garage doors. Their R-values are often estimated, borrowed from unrelated applications, or standalone, and they can create long-term issues such as water absorption or added door strain.
ThermaDoor is the only purpose-designed garage door insulation in Australia with verified dual-season R-values (R1.48 winter / R1.43 summer) calculated to AS/NZS 4859.1 & 2:2018. It is aligned with AS 3999 installation standards and engineered for long-lasting performance.
Yes. ThermaDoor’s verified R-values can be used by energy assessors in NatHERS modelling. This makes it a reliable, cost-effective way to boost energy ratings and reducing heating/cooling costs.
