Acoustic Sound Board SHEET 4' x 10', R4 1", R6 1.5", R8 2"

Description One 4' X 10' Duct board Sheet

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

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.
