C-MUTE SYSTEM™ 63 - Ceiling Sound Insulation

C-MUTE SYSTEM™ 63 is DECIBEL’s most powerful thin-panel ceiling solution from the C-MUTE series, designed for environments where maximum soundproofing is essential. With greater thickness, it blocks noise more effectively than both the 23 mm and 33 mm systems, making it ideal for demanding residential, commercial, and public applications.

Living and working without the constant intrusion of voices or sounds from above. The two-way noise filtering C-MUTE SYSTEM™ 63 brings that vision to life by combining cutting-edge acoustic science with precision engineering and discreet design. C-MUTE SYSTEM 23, 33, and 63 are all superior to old-school drywall soundproofing methods.

How It Works

Built on the Mass-Spring-Mass principle, C-MUTE SYSTEM™ 63 employs two heavy layers separated by an insulating gap to significantly weaken sound transmission.

Using DClox™ patented fasteners, the panels connect to the ceiling at less than 1% contact area, effectively isolating vibrations. The combination of advanced Finite Element Modelling (FEM) and independent European laboratory testing ensures reliable and repeatable results, even under challenging acoustic conditions.

Key Benefits
