ThermaDoor Garage Door Insulation Panels Western Australia
If you’ve been searching for garage door insulation kits Western Australia that truly work, the ThermaDoor DIY panels deliver tested, purpose-built results.
Western Australia’s weather can significantly impact garage temperatures, with intense summer heat causing garages to become extremely hot, especially in the north, while cooler southern winters may keep them chilly and damp. The temperature inside your garage has a big impact on your home’s comfort, energy efficiency and even power bills.
Why Choose ThermaDoor?
ThermaDoor is proudly Australian owned and manufactured. Our garage door insulation panels are Australia’s original, purpose made garage door insulation – designed specifically for sectional and tilt style doors.
Each panel in our DIY garage door insulation kit is:
- Made from 35mm high density construction grade EPS
- Backed with a laminated construction grade sisalation foil to block radiant heat
- Finished with a durable, impact resistant vinyl laminate – tough, and wipe down to keep clean
- Made to fit neatly inside your garage door panels with no mess or visible fixings
Proven R-value performance
Installation of our garage door insulation includes a built-in air gap that contributes to ThermaDoor’s thermal values to be independently calculated at R1.48 (winter) and R1.43 (summer) in the garage door. This means our R-values aren’t just claims based on wall, floor or ceiling insulation or ‘standalone’ material R-values that don’t apply to the unique environment of the garage door.
Our stated R-values are backed by engineering reports specific to the garage door.
Whether you’re building or retrofitting, our insulation kits are designed to boost energy efficiency, supports 7-star NatHERS designs, and meet the latest NCC 2022 energy compliance standards.

Why insulate your garage door?
Insulating your garage door stops one of the biggest, leakiest surfaces in your home from behaving like a giant radiator in summer and an ice pack in winter. A bare metal door soaks up heat and cold, then dumps it straight into the garage and the rooms beside or above the garage – driving up energy use and making living areas uncomfortable. Proper purpose made garage door insulation:
- Creates a thermal barrier – a layer that slows down heat transfer between two spaces
- Stabilises temperatures
- Adds additional padding that reduces noise transfer in and out of your garage area
- Protects stored items from extreme temperature swings
- Helps your heating and cooling system work the way they’re meant to

Frequently asked questions
Why should I insulate my garage door in Western Australia's climate?
Insulating your garage door helps regulate temperatures inside the garage, which is especially beneficial in WA’s hot summers and cool southern winters. It keeps the heat out during scorching days (particularly in the north) and retains warmth during colder months in the south, improving comfort and energy efficiency.
What type of insulation works best for garage doors in WA?
ThermaDoor is Australia’s original purpose made garage door insulation. It is not just repurposed wall or ceiling insulation stuck into a garage door. It has a calculated thermal value of R1.48 (winter) / R1.43 (summer) in the garage door. It has a construction grade polystyrene core with a laminated, easy clean vinyl face and a laminated construction grade sisalation foil backing (the material that your house is wrapped in for thermal protection). While there are other materials marketed as garage door insulation – we don’t believe anything comes even close to our purpose made, Premium garage door insulation.
How long does a typical DIY install take?
A confident DIYer can finish a double sectional door in an afternoon using ThermaDoor’s pre-cut kit. We provide you with access to our ‘How To’ video library to assist you step by step.
