Sound Fighter Systems – RetroSorb® Sound-Absorptive Panels

Date published: Tags:

RetroSorb® is a high-performance, sound-absorptive panel system designed specifically for outdoor applications. Whether you’re retrofitting existing reflective structures or seeking a robust solution for new installations, RetroSorb® delivers unmatched durability, acoustic performance, and long-term value.

Outdoor Sound Absorbing Panels

Why Choose RetroSorb®?

  • All-Aluminum Construction:
    Unlike traditional perforated steel panels, RetroSorb® uses non-corrosive, perforated aluminum. This eliminates the inevitable rust and degradation associated with steel, making RetroSorb® ideal for harsh outdoor and coastal environments.
  • Long-Lasting Durability:
    Every panel is powder-coated with UV-stabilized finishes after perforation. This ensures no direct metal exposure, even in perforated holes and cut edges, maximizing resistance to corrosion and extending product life.
  • Exceptional Acoustic Performance:
    RetroSorb® boasts a Noise Reduction Coefficient (NRC) of 0.95, verified per ASTM C423-09a. This means it absorbs up to 95% of incident sound energy, dramatically reducing unwanted noise from reflective surfaces such as concrete/CMU walls, metal buildings,  and more.

  • Architectural Appeal:
    Clean lines and premium color options allow RetroSorb® to blend seamlessly with modern designs, enhancing both function and aesthetics in commercial and industrial settings.
