  • Pre-Assembled Noise Enclosures

    Pre-Engineered ● Factory Finished ● High Performance ● Rugged Portability

    IAC Pre-Assembled Noise Enclosures offer a high performance, cost-effective alternative to field built solutions using conventional construction materials or modular acoustical components. Our pre-assembled noise control structures are the ideal solution for projects with limited time, space or funding. By controlling every aspect of the design and assembly in our factory, we can guarantee levels of mechanical, structural and acoustical performance that are difficult to achieve in the field.

  • Construction Basics & Available Options

    The construction method will depend on the design and performance criteria specified for any given project.  For medium duty industrial and commercial applications, we typically base the design around using our modular acoustical panel system called Panl-Wall™ and incorporate unitized assembly methods and floors when required.  This can be as simple as assembling a modular panel enclosure to a unitized base frame or floor with fork-lift capability or as in depth as a more robust structure requiring greater portability, high acoustical performance and resistance to severe environments where we begin with a complete, fully welded structural sub-frame upon which we will construct walls and ceiling with either pre-engineered modular components or built-up insulated construction with steel skins.

    Acoustical Performance Options

    • Wall construction available up to 10” thick
    • Sound Transmission Loss Ratings to STC 62
    • Interior Sound Absorption Ratings to NRC 1.05
    • Fully insulated and vibration isolated floors

    Durability Options

    • Components constructed from electro-galvanized steel, G90 galvanized steel, cold rolled steel, aluminum and stainless steel.
    • Standard construction material gauges from 22 gauge to ¼” steel plate.
    • Weather package available for outdoor applications.
    • Severe duty exterior protection suitable for steel mills and heavy industry applications.

    Available Doors & Windows

    • Wide range of personnel doors available in custom or industry standard sizes with acoustical ratings to match the project requirements up to STC-52.
    • Sliding doors available in similar sizes and performance.
    • Many styles of multi-layer glazed windows using tempered, laminated, or wire reinforced glass; polycarbonate and impact / bullet resistant units to UL Level 3.
    • Sloping or cantilevered windows and walls available.

    Ventilation & Electrical Options

    • Complete range of silenced ventilation and climate control  packages.
    • Variety of electrical lighting, power distribution and accessories.
    • Concealed electrical and cable raceways are available in the floor with access covers for convenient data and cable routing.

    Interior Finishes

    • Painted interior wall surfaces are typically perforated and acoustically absorptive.  Painted solid interior surfaces are available and may be treated with individually mounted decorative fabric acoustical panels.
    • Floors may be supplied as flat or diamond steel plate, and may be finished with a variety of industrial grade paint, tiles and coverings.
    • Custom work benches, tables, and shelves are available.

    Exterior Finishes

    IAC can provide quality factory finishes to any of our structures including:

    • Industrial duty air-dry enamel paint systems
    • Exterior and marine duty catalyzed epoxy and chemical cure paint systems
    • UV inhibited paint coatings
    • Tnemec Endurashield® outdoor coatings
    • Textured finishes
    • Factory applied weather resistant roof coverings

    Portability Options

    • Fork liftable from the base using dedicated fork tubes
    • Crane liftable from base or top using fixed or detachable lifting brackets
    • Base casters and levelers available for some applications requiring roll-around portability
