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.
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.Β
- Cost-effective performance: Delivers excellent thermal efficiency at a lower price point compared to bulk insulation materials.
Why Should You Care About Proper Installation?
