GreenStuf® Sound Solution is designed for the acoustic insulation of timber-framed buildings. It reduces airborne sound, impact noise and noise transmission by controlling resonating noise inside the construction cavity. Sound Solution is ideal for internal walls and mid-floor cavities, and comes as insulation segments and rolls pre-cut to fit standard timber framing.
GreenStuf Sound Solution can be used in timber framed walls and mid-floor cavities for reducing airborne sound transfer. GreenStuf 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.

The New Zealand Building Code (NZBC) sets out minimum performance ratings for inter-tenancy walls and floor-ceiling construction. The performance of a construction system relies on the design, materials and installation. Acoustic design for NZBC compliance requires specialist design considerations. To ensure Building Code compliance, architects and building designers are advised to consult an engineer or the relevant NZ standards before specifying acoustic insulation products. For information and assistance please contact a GreenStuf account manager.
NZBC Compliance: When installed in accordance with the manufacturer’s instructions, GreenStuf insulation will satisfy the 50 year durability clause NZBC B2.3.1 (a). GreenStuf meets the relevant clauses of NZBC E3 Internal Moisture, F2 Hazardous Building Materials, and may contribute to meeting H1 Energy Efficiency, and G6 Acoustic Design requirements.
H1 Energy Efficiency: This product will contribute to a building meeting building code Clause H1. All GreenStuf thermal insulation is created to meet with MBIE's new changes.
Fire Regulations: GreenStuf insulation may not be suitable for all applications, as stipulated in the NZBC. Please consult a fire engineer when specifying GreenStuf insulation or contact a GreenStuf account manager for further information.
Acoustic Performance: The Sound Transmission Class (STC) is the industry accepted means of determining a material or assembly’s ability to resist airborne sound transfer. A higher STC rating blocks more noise from transmitting through a construction system. GreenStuf Sound Solution will assist in reducing the resonating noise inside the construction cavity. Typical improvement in sound transmission loss through walls with the use of GreenStuf Sound Solution is an increase of 6-7 STC points, effectively reducing loud voices to a slight murmur. Typical improvement in sound transmission loss through a common residential mid-floor construction with the use of Sound Solution is an increase of 5-7 STC points.
GreenStuf thermal and acoustic insulation is made from 100% polyester fibre, with a focus on zero waste and recyclability, it contributes to improved air quality, and is safe to touch.
