Best Shed Insulation for Summer in Perth

Best Shed Insulation for Summer in Perth

If your shed turns into an oven during Perth's scorching summer, you’re not alone. Uninsulated sheds absorb heat rapidly, making them unbearable to work, store, or relax in. The good news? With the right shed insulation, you can significantly cut the temperature and make your shed usable all year round.

Why Insulate Your Shed?

Whether you use your shed as a workshop, home gym, or studio, insulation provides key benefits:

  • Keeps heat out in summer and warmth in during winter
  • Protects tools, furniture, and stored items from heat damage
  • Reduces condensation and moisture build-up
  • Creates a more comfortable, liveable space

Top Shed Insulation Materials for Summer

1. ThermalBreak 7 (Foil-Faced Barrier)

This 7mm foil insulation works wonders under tin shed roofs and walls. It acts as a radiant barrier that reflects up to 95% of radiant heat—perfect for Perth’s harsh sun. Install it just under the cladding or as a wrap to block incoming heat.

2. Earthwool R2.0–R2.7 Wall Batts

For shed walls, Earthwool batts provide both thermal and acoustic insulation. They're low itch, non-combustible, and made for Aussie conditions. A 90mm or 75mm thick batt fits standard steel framing perfectly, and they’re easy to DIY.

3. Earthwool FloorShield

If your shed is raised, hot air can sneak in from below. FloorShield batts help maintain comfort and block heat transfer from underfoot. They also reduce noise and protect from draughts.

How to Insulate Your Shed

Here’s a basic breakdown of what to insulate and with what:

Tips to Maximise Cooling

  • Add a whirlybird or vent to expel trapped heat
  • Shade the shed with trees or a pergola
  • Consider a window or fan for air circulation
  • Seal gaps and fix any leaks before insulating
