GreenStuf ADW is designed to be fitted without gaps around ducting, edges to be overlapped and sealed with tape. Where used to control condensation, the ducting wrap must be fully sealed to prevent moisture ingress. Deviations from the above must be consulted with the specifying engineer.

To ensure Building Code compliance, architects and building designers are advised to consult an engineer or the relevant NZ standards before specifying thermal and acoustic insulation products. For information and assistance please contact your GreenStuf account manager.

NZBC Compliance: GreenStuf ADW, when installed in accordance with the manufacturer’s instructions, will satisfy the 50-year durability clause NZBC B2.3.1 (a). GreenStuf meets the relevant clauses of NZBC C3.4(a) Prevention of Fire, E3 Internal Moisture, F2 Hazardous Building Materials, and contributes to meeting H1 Energy Efficiency requirements. 

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 your local GreenStuf account manager for further information. 

Thermal performance: GreenStuf ADW thermal performance has been tested internally to ASTM C518 using the procedures of ASTM C653 including the modifications specified in AS/NZS 4859.1. The R-value of flexible ducting insulation is calculated according to the formula prescribed by H1/VM3 and varies with the duct diameter. The declared R-value represents the minimum thermal resistance that can be achieved when installed in duct sizes varying from 100mm to 600mm diameter. GreenStuf’s e-foil facing enhances thermal performance by reflecting heat away from the surface, thereby enhancing the thermal resistance of the adjacent air film layer.

Acoustic performance: GreenStuf ADW will reduce noise transfer through ducting and help the attenuation of fan noise. Total noise and insertion loss in ducting depends on the absorption of the insulation material, coverage applied, and the design of the individual duct and its layout. For further information please contact your local GreenStuf account manager. 

Non-Toxic, Non-Allergenic, Non-Irritant: There are no known hazards with the use or handling of GreenStuf polyester. 

Durability: GreenStuf has a 50 Year durability warranty. Respiratory Safe: Polyester fibres used in GreenStuf are above 20 micrometres in size and will not reach the lower respiratory tract when inhaled. 

Fire ratings: ISO 9705: 1993 Classification: Group 1-S Smoke Production Rate: <5.0m2/s As required by NZBC C/VM2 FI 5550 

Maximum service temperature: GreenStuf ADW can be used in environments with temperatures not exceeding 90°C. 

Vermin: GreenStuf is naturally resistant to insect and vermin attack and does not contain chemical deterrents. Birds and vermin will live and nest in all bulk-fibre insulation materials if allowed access. In high-risk areas, GreenStuf recommends ensuring that the building perimeter is vermin proofed. 

Non-corrosive: GreenStuf polyester is considered non-corrosive based on AS/NZS 4859.1 Standard for insulation. 

VOC emissions: GreenStuf has been tested for chemical emissions in accordance with ASTM D5116 and is considered as a low VOC product. VOC concentration: 0.01 mg/m3 (7 days). 

GECA/GreenGuard Limit: 0.25 mg/m3 (7 days).
