‘Sillon‘ means 'groove' in French, and is a modular cork panel designed to create seamless, large-scale acoustic walls.
Inspired by architectural repetition, each tile can be rotated in any direction on all four sides, allowing designers and architects to create a variety of patterns and visual variations to create elegant continuity.
The delicate grooves flow naturally into the overall composition, giving the wall a soft, sculptural presence.
Made from 100% natural cork with no additives or chemical treatments.

That figure is valid forType A mounting to ISO 354:2003: tiles laid flat against the surface, butted tight, with no air gap behind. A gap or a batten changes the result
Reading the figuresαw is the single-number rating of ISO 11654, weighted across frequencies. NRC comes from ASTM C423 and averages four octave bands. They are not interchangeable
What it doesCork takes the edge off a room rather than deadening it. For a rated ceiling absorber, specify one

InstallationModular, wall-mounted, indoor use only. Each tile can be turned, so the pattern is set on site
Conditions of useIndoor only · 40% to 80% relative humidity · away from direct sunlight, water, heat and mechanical stress
CareDust it as you would a shelf. No water, no heat
Natural variationEach tile is a natural product: slight differences in colour and thickness are normal, and junction points can stay visible after installation
