ACRYLITE® Soundstop Structure Mounted Noise Barriers Technical Information

Product

ACRYLITE® Soundstop Structure Mounted Noise Barrier Systems provide effective noise abatement without the tunnel effect created by traditional non-transparent noise barriers.

Benefits

  • Maintains visibility for business and property owners.
  • Allows natural light onto roadway and into backyards.
  • Complete systems weigh as little as 12 pounds per square foot.
  • 30-year warranty - panels will not yellow or haze despite decades of outdoor exposure.
  • ACRYLITE® Soundstop GS CC panel option prevents panel fragments from falling if an accident causes panels to fracture.
  • Available FHWA approved Crash Tested system (tested to NCHRP 350).
  • BirdGuard stripe and tinted colors available.

General Information

Structure mounted systems commonly utilize posts at 8’ intervals but may be shorter or up to 16’ wide depending on project and state requirements.

Barriers may utilize ACRYLITE® Soundstop transparent noise barrier panels, ACRYLITE® Soundstop GS CC transparent noise barrier panels with fragment retaining filaments, or ACRYLITE® Soundstop NT non-transparent noise barrier panels.

ACRYLITE® Soundstop Structure Mounted Noise Barriers may be mounted to the top or back face of approved concrete bridge rails.

Specifications

  • Typical system weights range from 12 to 25 pounds per square foot. Increasing barrier heights and design wind loads are the main factors affecting system weight.
  • Posts may be spaced up to 8 feet wide for single transparent panels, without structural horizontal framing, up to 20’ high. See Example Plan View #1 below.
  • Posts may be spaced up to 16 feet wide (subject to authority limitations) with structural horizontal framing, up to 32’ high. See Example Plan View #2 below.
  • Systems are capable even for very high design wind loads typical of coastal, hurricane prone areas.

ACRYLITE® Soundstop panels pass the Miami Dade County (ASTM E 1996/97-02) Impact Test, showing no damage from the large missile impact test.
