Introduction

Mute Flat brings acoustic control to walls in its most direct form. The panel is made from PET felt, a soft and porous material with effective sound-absorbing properties. No pattern, no profile, just a clean surface that absorbs noise and integrates quietly into any interior. Mount it flush to the wall or with a cavity for improved performance. Suitable for offices, open-plan spaces, restaurants, and anywhere speech clarity matters. Available in 11 colours to blend with or contrast against your material palette.

Mute Flat is the foundation of the Mute family. A clean, uninterrupted surface that absorbs sound and integrates seamlessly into any wall composition. Use it to cover large areas uniformly, or combine it with textured Mute variants to create depth and visual contrast. The slim profile leaves more usable floor space whilst still delivering effective acoustic performance.

11 PET Felt Colours

Eleven unique PET felt blends, each with its own texture and depth. Minor colour variations between batches are a natural result of the recycled content in the material.

Acoustic Performance

Good acoustics start with the right setup. The results below show how mounting method affects performance, so you can choose what works best for your space.

Direct on wall

Direct on wall

The simplest installation. Mount the panel flush to the wall for a reliable acoustic result. A good starting point for spaces where installation depth is limited.

50mm cavity

50mm cavity

Add a 50 mm air gap behind the panel and performance improves noticeably. The cavity gives sound waves more room to dissipate.

50mm + rockwool

50mm + rockwool

Fill that same cavity with rockwool and the panel reaches its peak performance. PET felt, air gap, and infill work together for maximum sound absorption without adding bulk to the wall.

Information section

Mute Flat offers a clean, uninterrupted surface that integrates seamlessly into any wall composition. The panels can be cut to size on site and installed horizontally or vertically depending on your design.

Material

Made from recycled PET Felt

Mute Flat is made from PET felt, produced from recycled plastic bottles. PET felt technology brings traditional production steps down to a single pressing technique. The material is recycled and recyclable, offering outstanding acoustic properties and sustainability. At end of life, the panels can be returned for recycling into new PET felt products.
