ThermaDoor Garage Door Insulation Panels Sunshine Coast - DIY & Pro Install

PREMIUM RANGE

If you’ve been searching the Sunshine Coast for garage door insulation kits that truly work, the ThermaDoor Premium range delivers tested, purpose-built results.

On the Sunshine Coast, humid afternoons and salty sea breezes can turn your garage into a Sauna while cool Hinterland nights or sudden southerly changes can make it cold after dark. From Caloundra to Noosa or into the Hinterland, these rapid shifts in temperature affect more than just the garage – they impact the comfort of nearby rooms, your home’s energy efficiency and even your power bills. ThermaDoor garage door insulation kits help regulate these temperature swings, keeping your home more stable, efficient and liveable all year round.

Why choose ThermaDoor Premium?

ThermaDoor’s Director Peter Hinton is a Sunshine Coast local, with our factory situation at Chevallum. That makes us proudly Australian owned and manufactured, and our garage door insulation panels are designed specifically for sectional and tilt style doors.

Each panel in our Premium 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 – touch and easy to clean
  • Made to fit neatly inside most garage door panels with no mess or visible fixings

Proven R-value performance

ThermaDoor Premium is independently calculated to R1.48 (winter) and R1.43 (summer) in the garage door. This means our R-values aren’t just claims based on walls, floors or ceilings.

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.

ThermaDoor warranty: Lifetime insulation core + 7-year laminated finish protection

Every ThermaDoor panel is backed for the life of your garage door. We guarantee the insulation core for as long as the door itself remains in service, and we cover the laminated vinyl finish and fixings with a separate 7-year workmanship and materials warranty. It’s our way of providing that the product you install today will keep performing – year after year – without hidden caveats or fine print.

Key benefits

  • Improved garage comfort year round
  • Lower heating and cooling bills
  • Reduce street noise
  • Our R-values are verified and calculated to AS/NZS 4859.1 & 2:2018. This means for new builds and major renovations, your builder can use ThermaDoor Premium to support reaching NCC 2022 7-star ratings.
  • Aligned with AS 3999 (Insulation installation)

Why Homes Need ThermaDoor Garage Door Insulation Sunshine Coast

Tropical heat & humidity: Sunshine Coast temps often exceed 30 degrees with high humidity that turns your garage into a sauna. ThermaDoor insulation helps keep the heat out and the comfort in.

Storm season protection: Unlike open cell insulation like polyester acoustic boards and blankets, fibreglass batts, and other fluffy, air permeable bulk materials, ThermaDoor’s laminated vinyl finish is water resistant and impact resistant, guarding against wind driven rain and flying debris during severe weather.

Cold winter mornings: Even in the subtropics, winter mornings can bite. Stepping into an uninsulated garage can be a shock to the system. ThermaDoor helps take the edge off.

Frequently asked questions

How much does garage door insulation cost

Typical supply and install range: $625 – $990 for a double door. ThermaDoor Premium (verified R1.48, vinyl face, sisalation foil back) lands at the top end of that bracket because its purpose made, includes mechanical fixing (not glued in) and spring adjustment. 

The Sunshine Coast experiences high humidity, salty air, and hot summers that can turn garages into ovens. Insulating your garage door with ThermaDoor Premium helps block radiant heat, reduces temperature fluctuations and helps keep adjoining rooms more comfortable – especially during Queensland’s swelterind days.

A confident DIYer can finish a double sectional door in about 3 hours using ThermaDoor’s pre-cut kit. Prefer a pro job? Our authorised garage door pros supply, fit and spring balance in around 2 hours – depending on the job.

Yes. ThermaDoor Premium is purpose built for Australian homes and performs exceptionally well in coastal climates. The durable vinyl laminated surface resists moisture and salt air and provides further protection to the construction grade EPS core – it won’t degrade or become waterlogged over time due to humid environments.
