Introduction

Mute Flow combines acoustic function with visual rhythm. The panel's distinctive wave pattern adds texture and depth to walls whilst absorbing sound. Made from PET felt, a soft and porous material with effective sound-dampening properties. Suitable for offices, restaurants, hotels, and open-plan spaces where noise control and visual interest go hand in hand. Available in 11 colours to complement or contrast with your interior palette.

The flowing wave pattern gives Mute Flow its name and character. The three-dimensional surface breaks up sound reflections whilst creating a subtle play of light and shadow across the wall. Use it to bring warmth and movement to large surfaces, or combine with other Mute variants for layered acoustic compositions.

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

Mute Flow's wave pattern is pressed in a single production step, creating a seamless surface without joints or seams. The panels can be cut to size on site and installed horizontally or vertically depending on your design.
