Secure bubble insulation between roof battens using staples or adhesive tape, ensuring the reflective side faces downward. Leave a 25mm air gap between insulation and roofing sheets for optimal thermal performance.
Insulating Under a Metal Roof?
Bubble insulation only works if it is installed with the right airflow and reflective gap. Our Sydney team can fit it properly so your roof stays cooler and quieter.
What Is Bubble Insulation and Why Does It Matter?
- Dual-layer protection: Bubble insulation combines reflective foil surfaces with air-filled bubble cells to block radiant heat and provide thermal resistance.
- Australian climate solution: Reflects up to 97% of radiant heat, keeping homes cooler in summer and warmer in winter across Sydney’s variable conditions.
- Moisture barrier: The foil layers prevent condensation buildup that can damage roof timbers and reduce insulation effectiveness over time.
- Lightweight installation: Weighs significantly less than traditional batts, making it easier to handle on roof structures without additional support requirements.
- Cost-effective performance: Delivers excellent thermal efficiency at a lower price point compared to bulk insulation materials.
Why Should You Care About Proper Installation?
- Energy savings: Correctly installed bubble insulation can reduce cooling costs by 35-40% during Sydney’s hot summers through effective heat reflection •
- Comfort improvement: Maintains stable indoor temperatures year-round by creating an effective thermal barrier between your living space and roof cavity Professional metal roofing Sydney installation ensures compliance with Australian Building Codes and manufacturer warranties remain valid
- Prevents condensation damage: Proper air gaps and vapour barriers protect roof timbers from moisture-related rot and structural deterioration
- Long-term durability: Quality installation extends both insulation and roof lifespan, protecting your investment for 20+ years

Frequently Asked Questions
What is bubble insulation and how does it work under a metal roof?
Bubble insulation is a reflective foil layer with an air-bubble core. Under a metal roof it reflects radiant heat and adds a thermal break, which helps keep the space cooler in summer and reduces condensation on the underside of the sheets.
How is bubble insulation installed under metal roofing?
It is laid over the battens or purlins with the reflective side facing the required air gap, fixed with staples or foil tape, and lapped and sealed at the joins. The air gap is what makes the reflective surface work.
Does bubble insulation reduce metal roof noise?
It helps. The layer dampens some of the drumming and thermal-movement noise, though it is not a complete soundproofing solution on its own. Combined with the right fixings it makes a noticeable difference.
Can I install bubble insulation myself?
Simple retrofits are possible, but getting the reflective side, air gap, laps and sealing right, and working safely at height, is where DIY jobs fall short. A poor install loses most of the benefit.
Is bubble insulation enough on its own?
It is a good reflective layer, but for full comfort most homes pair it with bulk ceiling insulation and proper roof ventilation. Together they control heat, cold and condensation far better than one alone.
