Hush Acoustic Duct Liner – 100mm R2.4

Hush Acoustic Duct Liner is a high-performance polyester thermal and acoustic insulation designed for lining the inside of HVAC ductwork.

Manufactured from safe, non-irritant polyester fibres, the 100mm thick liner provides R2.4 thermal insulation, helping to reduce fan and airflow noise while minimising heat transfer through ductwork.

Suitable for rectangular and oval ducting, its self-supporting construction helps maintain its shape and performance.

Ideal for residential and commercial air distribution systems where higher levels of thermal insulation and effective noise reduction are required.

Features & Benefits

• Acoustic insulation – Helps absorb fan and airflow noise within ductwork.

• R2.4 thermal insulation – Reduces unwanted heat transfer through duct surfaces.

• Non-irritant polyester – Comfortable to handle.

• Self-supporting construction – Helps retain its shape.

• 100% recyclable material – Manufactured from recyclable polyester fibres.

• Versatile applications – Suitable for rectangular and oval ductwork.

• 100mm thickness – Provides the highest thermal resistance of the four Hush products listed.

Frequently Asked Questions

What is the purpose of Hush Acoustic Duct Liner?

Hush is designed to reduce noise transmission through HVAC ductwork while providing thermal insulation.

What is the thermal resistance of the 100mm Hush Duct Liner?

The 100mm Hush Acoustic Duct Liner provides R2.4 thermal resistance, the highest R-value of the four products listed.

What size are the sheets?

Each sheet measures 1200 × 2400mm, covering 2.88m².

What is the difference between the 75mm and 100mm Hush Duct Liner?

The 100mm version provides higher thermal resistance (R2.4 compared with R2.0), making it suitable for applications requiring additional thermal insulation. The thicker material also requires more internal duct space.

Can Hush be used in residential and commercial ductwork?

Yes. It is suitable for residential and commercial HVAC applications where internal duct insulation is required.

Is the material safe to handle?

Hush is manufactured from non-irritant polyester fibres, making it comfortable to handle.
