Acoustica Rigid Duct (ARD) Thermal & Acoustic Duct Lining

Acoustica Rigid Duct (ARD) is lightweight, high density acoustic/thermal insulating material, manufactured from thermally bonded polyester with perforated foil laminated to one side.

Acoustica Rigid Duct (ARD) is used for internal lining of rigid duct work and air conditioning plenums, to provide excellent noise absorption and thermal insulation in ducting.

ARD reduces sound transfer from fans, motors and air turbulence within the duct to external sources and reduces the sheet metal clicking and popping noises caused by expansion, contraction and vibration.

Acoustica Rigid Duct (ARD), with a durable perforated foil facing (approx 22% open area), is suitable for ducting environments with rated velocities to 50 m/sec when installed in accordance with the directions.

Completely safe to use, Acoustica Rigid Duct (ARD) is environmentally friendly, safe and clean to handle, with no fibre migration. ARD is fire safe and rated to Australian and international fire standards are follows:

Acoustica Rigid Duct (ARD) comes in the following sizes:
