F-MUTE SYSTEM™ 23 – Thin Soundproofing for Floors

F-MUTE SYSTEM™ 23 is DECIBEL’s ultra-thin floor soundproofing solution, engineered to reduce both airborne and impact noise transmitted through floor structures. Developed by DECIBEL’s acoustic engineers, this ultra-thin system combines a dense fibreboard with a resilient acoustic foam layer to improve sound insulation between floors.

From apartments and offices to restaurants, studios, and factories, F-MUTE SYSTEM™ 23 delivers effective airborne and impact sound insulation while remaining easy to install.

The soundproofing system reduces both airborne and impact noise while keeping floor build-up to a minimum, at only 23 mm. Validated through Finite Element Modelling, it meets real-world demands, delivering dependable floor soundproofing with minimal disruption.

How It Works

F-MUTE SYSTEM™ 23  is engineered as a precise combination of an extremely dense fibreboard and a non-flammable, acoustic foam backing. This dual-layer structure isolates the floor from the supporting structure, helping reduce both airborne sound transmission and impact noise.

Key Benefits

• High airborne and impact sound insulation.
• Ultra-thin 23 mm panel, ideal where floor height is limited.
• Easy to install over a wide range of floor structures.
• Eco-friendly materials for sustainable construction.
• Effective acoustic performance across a wide frequency range.

Installation Overview

F-MUTE SYSTEM™ 23 is designed for installation over concrete, steel, and timber floor structures and can be used below laminate, parquet, carpet, lino, engineered boards, and tiled finishes, subject to the appropriate finishing build-up. Panels are laid directly onto the existing structure, and then you can finish it with a variety of floorings like carpet, lino, engineered board, or timber flooring.

The system is DIY-friendly, though DECIBEL can provide professional installers on request. Once installed, it provides a discreet and long-lasting acoustic barrier without compromising interior design.
