  • Noishield® Outdoor Noise Barriers

    Pre-Fabricated ● High Acoustical Rating ● Weather Resistant ● Easy Installation

    IAC Outdoor Noise Barrier Noishield product line consists of pre-engineered, modular acoustical components that can be easily configured and assembled into enclosures, screens, partial enclosures and barriers to provide sound attenuation for many kinds of outdoor industrial, community and environmental noise problems. 

    Outdoor noise problems, also known as community noise problems, environmental noise problems or simply noise pollution tend to refer to issues of noise related disturbances in a community or neighborhood caused by outdoor noise sources such as traffic, cooling towers, rooftop mechanical equipment, air conditioners, generators, manufacturing facilities, deep well pumps, utility sites and construction. Untreated, these noise sources may violate state and local noise level regulations based on zoning or cause annoyance in the community, disturb sleep or interfere with quality of life.

    IAC can solve these problems with a properly designed Noise Barrier Wall, Screen or Noise Enclosure using our Moduline Noishield line of modular acoustical metal panel products.


  • TYPICAL APPLICATIONS

    Our horizontal interlocking panel design creates a sleek, weather resistant assembly that combines high acoustical characteristics with robust structural stability to stand up to the elements. Available in either a high STC sound barrier only version, or our soft side barrier absorber combination, these modules are easy to assemble into many varying configurations such as:

    • Rooftop Equipment Screens
    • Highway Sound Barriers
    • Outdoor Utility Sound Enclosures
    • Cooling Tower Noise Enclosures
    • Chiller Screens
    • Generator Enclosures
    • Airport Sound Barriers
    • Loading Dock Noise Screens
    • Air Conditioner Enclosures
    • Transformer Enclosures
    • Substation Noise Barriers
    • Construction Noise Barriers
    • Deep Well Pump Enclosures
    • Rail Yards

  • CONSTRUCTION FEATURES

    • Standard panel modules available in 4” and 5” thicknesses
    • Panel modules available in 18", 24”, 36” and 48” units
    • Panel lengths available up to 20’-0”
    • Panels are self draining
    • Formed interlocking edges do not require any separate panel joiners
    • Standard panel Sound Transmission Loss Ratings to STC 33
    • Standard panel Sound Absorption Ratings to NRC 1.05
    • Panels and components constructed from electro-galvanized steel, G90 galvanized steel, cold rolled steel, aluminum and stainless steel for optimum weather, corrosion and abuse resistance
    • Complete structural support systems available

    Structural Integrity
     

    When installed with a properly designed support system and concrete footings, Noishield barriers and enclosures can resist wind velocities to 110 MPH and most common snow and seismic loads. IAC can provide design and manufacture of the required structural support frame upon request.
