Hush Acoustic Duct Liner – 50mm R1.2

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 50mm thick liner provides R1.2 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 improved acoustic performance and higher thermal insulation are required.

Features & Benefits
