Insulating a Workshop or Garden Shed? Here’s What You Need

Whether you’re converting a garden shed into a workspace, gym, or studio — or simply want to protect stored gear — shed insulation is the key to comfort and durability in Perth’s harsh climate.

So, what materials should you use? And how can you make sure it lasts? Let’s break it down by area.

Start with the Roof

The roof takes the most heat load, especially during Perth’s dry summers. Without insulation, the temperature inside your shed can skyrocket past 40°C by midday.

• Ametalin SilverSark – A reflective foil that blocks radiant heat under metal roofing.
• ThermalBreak 7 – Combines thermal resistance and radiant protection in one step.
• Earthwool R4.0 – Perfect for fully lined workshop ceilings or pitched roofs.

Wall Insulation for Year-Round Comfort

Wall insulation stabilises interior temperatures and reduces noise transfer from tools or nearby neighbours.

• Earthwool R2.7 HD – High-performance wall batts with excellent acoustic value.

Don’t Forget the Floor (If It's Raised)

Timber-floored sheds benefit massively from underfloor insulation, especially in winter.

• Earthwool R2.5 Floorshield – Stops cold air from rising through your floorboards and keeps your feet warmer.

Condensation Control

If your shed is powered, sealed, or used regularly, managing internal moisture is a must. Reflective foil like Ametalin or ThermalBreak helps reduce condensation risk, especially under metal roofs and walls.

Optional Extras

• Acoustic Insulation – If you’re using power tools or audio gear, acoustic-rated batts can help reduce sound transfer.
• Vapour Barriers – For fully lined and powered sheds, a vapour barrier can be layered behind batts for additional moisture protection.

Conclusion: Build a Better Shed

If your shed is more than just storage, insulation transforms it into a usable space year-round. It helps regulate temperature, cuts condensation, and protects your equipment or workspace — all with easy-to-install products from Perth Insulation Centre.
