Scope of Use

GreenStuf Sound Solution can be used in timber framed walls and mid-floor cavities for reducing airborne sound transfer. Sound Solution reduces resonating noise in the construction cavity thereby reducing the sound energy transferred from one side to the other. Further improvements can be achieved by using acoustically rated plasterboard, multiple layers of plasterboard, or by isolating the plasterboard from the stud.

GreenStuf Sound Solution will assist in reducing the resonating noise inside the construction cavity.

Limitations on Use

The performance of a construction system relies on the design, materials and installation. Acoustic design for NZBC compliance requires specialist design considerations.
