>What’s the secret to a comfortable, energy-efficient home? It might not be what you think. While a new roof is essential, the real magic happens beneath the surface: insulation. Choosing the right type can make all the difference in your long-term comfort and savings.
The different insulation materials available on the Australian market offer unique advantages and choosing the right one depends on factors like your local climate, budget and performance expectations for your property.
Insulation Options For Residential Roof Repair in Perth
1. Glasswool Insulation
- R-Value: R2.5 – R5.0
Glasswool insulation, made from recycled glass, is an excellent option for thermal and acoustic insulation. It is lightweight, non-combustible and cost-effective. Available in batts or rolls, it provides superior soundproofing while resisting moisture.
2. Polyisocyanurate (PIR) Board Insulation
- R-Value: R5.6 – R8.0
PIR board is a rigid foam insulation with high thermal performance. It has a closed-cell structure, which makes it extremely resistant to moisture and humidity.
3. Expanded Polystyrene (EPS) Insulation
- R-Value: R3.5 – R4.5
EPS insulation is lightweight and durable, providing reliable thermal insulation with excellent compressive strength. It is commonly used in metal roofing applications.
4. Reflective Foil Insulation
- R-Value: Variable, often combined with bulk insulation
Reflective foil insulation is ideal for reducing radiant heat transfer, making it perfect for our dry, hot climate. It is usually paired with other insulation types for enhanced performance.
5. Spray Foam Insulation
- R-Value: R3.7 – R6.0 per inch
Spray foam insulation expands to fill gaps, creating an airtight seal. It is particularly effective for preventing air leakage and improving overall energy efficiency.
Understanding the R-Value
R-value tells you how effective insulation is at preventing heat from flowing through it. A higher R-value means the insulation is better at blocking heat, keeping your home comfortable year-round.
Australian building regulations, overseen by the ABCB, specify minimum R-values for insulation based on where you live. Choosing the right insulation for your climate zone ensures your home is up to code and helps you save on energy bills.
Why The Right Insulation + Wrong Installation = A Disaster
Even the highest-rated insulation won’t perform as expected if it’s not installed correctly. Think of it like buying a high-performance car but never changing the oil – eventually, it’s going to break down.
Common DIY installation mistakes, like compression (squashing the insulation) or leaving gaps, drastically reduce its R-value and effectiveness. These issues create thermal bridges, allowing heat to escape in winter and enter in summer, negating the benefits of your investment and costing you more in energy bills.
