Product overview

C - MUTE SYSTEM™ 23 is a thin, point-connected soundproofing system for ceilings, developed and refined over the years by the R&D department of DECIBEL.

C - MUTE SYSTEM™ 23 panels are mounted with 8 specially designed anti-vibration DClox™ fastening elements, patented in the EU. 

The innovative fasteners are made of special elastomers, making them an effective vibro insulation point connection between the existing ceiling and the panel. Their geometry reduces the rate of sound transmission and minimises the contact area between the soundproofing panels and the existing ceiling to below 1%

Weighted airborne sound reduction index (Rw) is tested in accordance with EN ISO 10140-2:2010.
Fire resistance classification of B, s1 - d0 is in accordance with EN ISO 13501-1:2018.

DClox™ Innovation

DClox™ is a patented fastener specially designed for the installation of C - MUTE SYSTEM™ soundproofing panels.

The innovative fasteners are made from special elastomers, making them an effective vibro insulation point connection between the existing partition wall and the panel. Their geometry reduces the rate of sound transmission and minimizes the contacting area between the soundproofing panels and the existing wall to below 1%.
