**K-FONIK FIBER** is a mechanically stable material made from polyester yarns. It
boasts excellent mechanical strength and structural stability, is dust-free, and
does not emit toxic substances. Installation can be accomplished using either mechanical
fastening or adhesive. It can be used as both a sound-absorbing and sound-vibration-
insulating material.

The material is used to solve the following problems:

 * reduction of ventilation system noise;
 * soundproofing of ceilings, walls, floors;
 * soundproofing of equipment housings;

     |  Technical parameters |  Values |  
 |  Sound absorption coefficient for a thickness of 50 mm, α |  0,9 |  
 |  Sound insulation index of a structure with integrated material * |  57 dB |  
 |  Impact noise insulation improvement index, ΔLy |  34 dB |  
 |  Density, kg/ ^(m3) |  40 |  
 |  Operating temperature, °C |  from -50 to +90 |
