Expandify homes use rockwool insulation throughout the roof, external walls (100mm), and internal walls (50mm), which naturally provides a high level of sound dampening.

Rockwool is known for its acoustic performance and is used across commercial and residential construction to minimise sound transmission.

Key details:

100mm thick rockwool in external walls (standard)

50mm rockwool in internal walls (standard)

Dual-layer rockwool in ceiling system (roof + ceiling)

There are no additional soundproofing upgrades currently offered, but the existing insulation system exceeds most residential acoustic expectations.
