Description

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;
