ROLFON™ is Hybrid Sound Absorbing Material (Hybrid Noise Absorbent). The patent is protected throughout Europe (Polish Patent Office No. P.397129).
The ROLFON™ invention offers two different sound absorbing mechanisms encapsulated in one „finishing material”: the resonant mechanism (characteristic for specific acoustical structures) and a mechanism employing flow resistance (characteristic for porous sound absorbents such as wool), while retaining the simplicity of installation and small size.
ROLFON production is eco-friendly and absolutely waste-free!
