K-FONIK B polyurethane foam panels
Description
A material with a developed, wavy surface and a rough texture. The material is available in two variants, depending on the source material. The K-FONIK ST B foam rubber variant (black) combines broken pores on the surface, closed pores within, and a wavy surface, making it possible to simultaneously insulate and reduce sound reflection.
A version based on polyurethane foam K-FONIK PU B (gray color) The combination of open pores and a developed surface of the material allows for the wide use of the material as an absorber and dissipator of sound energy.
It is used as:
- Reduction of aerodynamic noise of air ducts;
- Sound absorption of equipment housings;
- Soundproofing of ventilation units.
During installation, both mechanical fastening and gluing are possible.
