Searching for “how to insulate a garage door on a budget”?
ThermaDoor Premium DIY kits are:
• More affordable than full supply & install services
• More effective than repurposed wall or floor insulation
• Purpose-designed for Australian panel-lift and tilt garage doors
Most homes do not require council approval. ThermaDoor panels are internal, reversible, and non-invasive. For strata complexes or heritage-listed homes, check with your body corporate or local council first.
• Gluing foam directly to metal skins
• Blocking essential air gaps
• Adding weight without spring adjustment
✅ ThermaDoor avoids all of these with purpose-made panels, mechanical fixing, and lightweight design.
An air gap in garage door insulation:
• Prevents condensation, mould, and rust
• Improves thermal performance
• Aligns with AS 3999 installation requirements
ThermaDoor kits are designed with a built-in air cavity for maximum compliance and performance.
In most Australian garages, a separate vapour barrier is unnecessary. ThermaDoor’s laminated foil backing acts as a moisture-resistant layer and radiant barrier in one.
