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.
