Parenthese is a bold cork tile inspired by the geometric elegance of 1950s and 60s wood paneling. Its structured design invites playful compositions with rhythm, perspective and contrast. Tiles can be rotated to form graphic patterns that evolve with your point of view, transforming flat surfaces into living, tactile walls.
Made from 100% natural cork, it offers excellent acoustic absorption while adding depth and visual sophistication to any interior.
Hypoallergenic Dust-free, allergen-free, safe for asthma sufferers.
Durable Stable, compressive-resistant, vapor-permeable. Not affected by rodents or chemical agents.
Retro-inspired texture, reimagined for modern spaces
Each Parenthese tile is a creative building block. Whether arranged in criss-cross layouts or checkerboard sequences, it becomes a dynamic skin that shifts as light moves through the room. The natural surface absorbs sound while diffusing warmth and softness into the space.
Low-maintenance, tree-friendly and rich in texture, Parenthese blends biophilic design with a strong visual identity. It is ideal for bold statements in offices, hotels or creative environments.

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
