QTY:

SilentFiber™ Acoustic Insulation Duct Liner designed to be applied to interior surfaces of sheet metal ductwork for HVAC systems in residential and commercial applications. Can also be used for insulation of appliances. SilentFiber™ Acoustic Duct Liner is manufactured from fiberglass wool combined with thermo-resistant resin with an interior coating that is reinforced with fiberglass.

To create a water-resistant and damage-resistant cure, apply Foster® 40-23 Duct Liner Insulation Sealer to the SilentFiber™ Duct Liner after installation with a brush or airless sprayer.

Insulation is applied inside the sheet metal ductwork for air systems operating at temperatures from 5°C (40°F) and 121°C (250°F), with the facing exposed to the airflow. The insulation shall be secured to the sheet metal ductwork using mechanical fasteners (impact-driven or weld secured) or an appropriate supporting tool.
