    Summer Proofing Your Older Home: Insulation and Ventilation Upgrades

    Summers in Western Sydney are notoriously hot. Older homes, particularly those built before modern energy efficiency standards, can feel like ovens during a heatwave.

    Surviving the Western Sydney Summer

    A renovation is the perfect time to address thermal comfort.

    Pro Tip: The Roof Cavity

    Don't just insulate the ceiling; ensure your roof cavity has adequate cross-ventilation to let trapped heat escape before it radiates down.

    The Importance of Insulation

    Many older homes have degraded or non-existent roof and wall insulation. Upgrading to high R-value batts can dramatically reduce your cooling costs and improve comfort.

    Ventilation Matters

    Proper roof ventilation, such as whirlybirds or eaves vents, helps extract trapped hot air from the roof cavity, preventing it from radiating down into your living spaces.
