Technical System Description

The system utilizes acoustic panels composed of a high-density rock fiber core, a 22 GA G90 galvanized perforated internal face to promote sound absorption, and a 16 GA G90 galvanized solid external face providing the mass required for sound attenuation. The modular design allows for adaptation to various equipment and configurations.

Structural System

Installation on a self-supporting structure sized according to wind loads and project requirements. Additional reinforcements and SIMIC cables can be integrated. Main components include 48 mm diameter 6061-T6 aluminum posts and rails, as well as 47.1 lbs ASTM A48 Class 30 cast steel counterweights with roof protection mats.

Support Components and Materials

  • 535 aluminum alloy for fittings
  • 6061-T6 aluminum tubes

Acoustic Performance

Performance is validated according to ASTM E90 (sound attenuation) and ASTM C423 (absorption coefficient). Results depend on insulation thickness, sheet metal gauge, and panel configuration.

Advantages

  • Exterior finish that harmonizes with building architecture
  • No penetration of the roofing system
  • Modular design that adapts to all equipment types
  • Noise reduction, resonance control, and echo control
  • Easy installation on all types of flat and low-slope roofs
