Description One 4' X 10' Duct board Sheet

Ductboard has the same insulating/soundproofing qualities as more expensive musical sound dampeners.

NOTE: Freight charges can be very expensive if shipped alone.

Knauf, Owens Corning or equivalent Air Duct Board-AGM is a resin-bonded fiber glass formed into rigid, rectangular boards faced on one side with a fire-resistant foil-scrim-kraft (FSK) vapor retarder and a lightweight fiber glass mat on the airstream surface. Available in EI-475 or EI-800, with a butt edge or a factory-molded shiplap edge, it offers excellent thermal and acoustical performance.

Application

Knauf, Owens Corning or equivalent Air Duct Board-AGM dual-temperature service where good temperature control and noise absorption are required.

Features

  • Low thermal conductivity of 0.23 at 75°F (24°C) mean temperature.
  • Low installed cost,
  • Excellent acoustical characteristics.
  • Non-woven all-glass mat facing on the airstream surface.
  • Assured insulation thickness, shiplap joints, and FSK vapor retarder.
  • If necessary, can be cleaned in accordance with NAIMA's
  • Knauf, Owens Corning or equivalent Air Duct Board systems meet the fire and smoke safety regulations of most federal, state, and local building codes.

Benefits

  • Fabrication in shop environment lowers field installation time.
  • One craft required to fabricate and install system.
  • Minimum capital investment for fabrication equipment.
  • Portability allows for assembly or fabrication at site.
  • AGM facing ensures a smoother airstream surface for a cleaner cut and added durability.
  • Condensation control.
  • Strong thermal performance.
