Introducing GreenStuf ADW and ARD: Premium Ducting Insulation Solutions

GreenStuf is adding two superior ducting insulation products to its range: GreenStuf Autex Duct Wrap (ADW) and GreenStuf Autex Rigid Duct Liner (ARD) — both designed to enhance the thermal and acoustic performance of HVAC (Heating, Ventilation, and Air Conditioning) systems.

GreenStuf Autex Duct Wrap (ADW)

GreenStuf Autex Duct Wrap (ADW) is a lightweight, flexible insulation material crafted from thermally bonded polyester with an e-foil finish on one side. It is specifically engineered to improve the thermal efficiency and sound absorption of external HVAC ducting. Available in various thicknesses and R-values, ADW provides effective thermal resistance and helps prevent condensation on cold air systems, reducing the risk of corrosion and ceiling stains.

ADW's e-foil finish acts as a moisture barrier, and its peel-and-stick backing option ensures easy installation without gaps, making it an ideal choice for maintaining the performance and integrity of HVAC systems. Manufactured from 85% recycled PET, ADW supports sustainable building practices and is safe to install without personal protective equipment (PPE). Its production locally in New Zealand ensures high-quality standards and reduced environmental impact.

GreenStuf Autex Rigid Duct Liner (ARD)

GreenStuf Autex Rigid Duct Liner (ARD) offers exceptional thermal and acoustic insulation for internal ducting applications. Made from 100% polyester with a durable black facing, ARD is suitable for all types of HVAC systems, handling low and high airflow volumes without requiring additional protection. Its rigid facing also safeguards the liner during installation, ensuring long-term performance.

ARD is available in multiple thicknesses and R-values, making it versatile for insulation needs. Like ADW, ARD is manufactured using recycled PET, containing a minimum of 60% recycled fibre. The safe, non-irritant composition allows for installation without the need for PPE.

Partnership and accessibility

Speaking with Marcel Herbke, General Manager of Sales NZ, he says, "Since the changes to H1, we've looked to partner with key players in the market to ensure our HVAC products are easy to access for all projects in all parts of the country. So specifying our ducting products ensures no unnecessary delays. They're easy to handle and easy to work with, and with our takeback programme, it's also easy to do the right thing with any offcuts."

"Both ADW and ARD offer architects and builders advanced insulation solutions that combine efficiency, durability, and sustainability. By choosing GreenStuf, professionals can ensure optimal HVAC performance, energy savings, and a healthier indoor environment."

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.

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 in 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
