Thermocell Reflective Foil Insulation
Engineered for Australian sheds. Thermocell combines a reflective foil face with fire-resdistant foam core to block radiant heat, reduce condensation, and dampen rain noise — without the itch, dust, or bulk of traditional insulation. Goes on the outside of your steel frame on new builds, with cladding screwed over the top.
Thermocell technology — trusted across thousands of Australian shed builds. Available in 3 thicknesses to match your climate and use case.
From Confused to Covered in Four Steps.
Build Your Insulation Plan
Answer 5 quick questions. We'll calculate exactly how many rolls you need, pick the right thickness, and give you a delivered price.
What size is your shed?
Measure the outside walls. We'll calculate roof + walls and add 10% for overlaps automatically.
Choose Your Thickness
All three options use the same Thermocell reflective foil technology. Thicker = more thermal performance. Every roll covers 30m² (1350mm × 22.25m).
Why We Love the
Neurock Thermocell
After 20 years in the shed game, we’ve seen every type of insulation under the sun. We love Neurock Thermocell because it finally solves the "itch" factor. It’s a 3-in-1 powerhouse that replaces traditional glasswool blankets, acting as your thermal barrier, vapour barrier, and radiant heat shield all in one.
Unlike the cheap "bubble wrap" alternatives that can deflate or delaminate over time, Thermocell uses a fire-resistant cellular core that stays rigid and performs for the life of your shed. It’s the "trade secret" for a shed that stays cool in a QLD summer, warm in a VIC winter, and quiet during a NSW downpour.
