PARENTHESE ACOUSTIC CORK WALL
SILLON ACOUSTIC CORK WALL
Designed by Alain Gilles
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.
