Earthwool External Wall Batts

Earthwool external wall batts for thermal and acoustic comfort

Earthwool external wall batts are a practical choice when you want better thermal performance and improved sound control in residential and light commercial builds. They’re commonly specified for framed external walls, especially where you’re trying to reduce summer heat gain and winter heat loss.

Where external wall batts are commonly used

• Timber or steel framed external walls behind plasterboard linings
• Projects where comfort and energy efficiency are priorities
• Homes in Perth and regional WA where hot days and cool nights can make insulation worthwhile

Key points to consider before you choose batts

• R-value: Choose an R-value that suits your wall build-up and climate zone.
• Vapour and condensation: In some wall systems, condensation control and ventilation details matter as much as R-value.
• Correct fit: Batts should fit the cavity without excessive compression or gaps.
