How to Choose

How to choose an acoustic or insulated flexible duct

Six steps to specify the right insulated or acoustic duct for your project.

Application

Define the application first: residential or commercial air distribution, ventilation, fresh air or exhaust.

Insulated or non-insulated

Choose insulated duct where thermal insulation is required, and non-insulated duct for general air distribution.

Insulation grade

Select the insulation grade that matches the thermal requirement; current products use R0.6, R1.0, R1.5 and R-8.

Acoustic requirement

Where duct-borne noise must be reduced, use acoustic flexible duct, an acoustic silencer or acoustic duct insulation.

Diameter and length

Confirm the inside diameter and the length required for each duct run.
