Hush Acoustic Duct Liner – 75mm R2.0

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 75mm thick liner provides R2.0 thermal insulation and an NRC rating of 0.8, 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 thermal insulation and effective acoustic performance are required.

Features & Benefits
