[APT] Acustone PET [RGH] Rough Concrete [10005] Middle grey
The most powerful spaces don’t just look right — they feel right. They sound right.
XSTONE Acustone PET in Rough Concrete texture and Middle Grey is a raw concrete acoustic wall panel that delivers two things most surfaces can only promise one: genuine sound absorption, and genuine architectural presence. The Rough Concrete texture brings an honest, tactile surface to the wall — fine granular reliefs and subtle directional marks that evoke process over polish, material over decoration. Strength without performance. Industrial integrity without coldness.
In Middle Grey — a soft, muted mineral depth with the quiet strength of natural stone, grounded and balanced like RAL7040 in its most elemental form — this texture becomes a perfect architectural backdrop. One that enhances light and materiality without imposing itself, allowing the space and the people within it to take centre stage.
Beneath the surface, 100% recycled polyester fibre — born from recovered plastic bottles, free from chemical binders — works continuously to capture sound energy, reduce reverberation, and transform ambient noise into calm. The result is an environment that is both visually disciplined and acoustically comfortable: the premium open-plan office, the luxury hospitality lounge, the high-end retail space, the conference room where clarity matters.
Fire-rated B-s1-d0. Non-toxic, non-allergenic. Circular by design.
Concrete that listens. Silence that looks like architecture.

Great Acoustic Performance
Thanks to its porous, open structure, PET felt absorbs sound energy and diffuses it naturally, reducing noise and reverberation while improving acoustic comfort across work and learning environments.
Built for longevity
PET felt is designed to last. Its resilient, impact-resistant structure holds its form and performance over time, even in the most active spaces, while remaining simple and effortless to maintain.
Shape for Design
PET felt invites creativity. Its flexible nature, rich palette of colors, and variety of textures and forms make it easy to shape, adapt, and integrate into any interior vision.
Recycled and Recyclable
Born from recycled plastic and designed for circularity, PET felt transforms waste into value, extending material life while reducing environmental impact.
