Diamond Grey

Diamond Grey Acoustic Cork Wall Panels

Sculpted grey diamonds in 30 mm cork that quiet a room the moment they go up.

Diamond Grey is a three-dimensional wall panel cut from compressed agglomerated cork in a cool grey tone. Each piece is a diamond measuring 424 mm (16-11/16 in) across the long diagonal and 245 mm (9-41/64 in) across the short one, and at a full 30 mm (1-3/16 in) thick it throws real shadow lines across the wall as the light moves through the day.

The geometry is not just decorative. The faceted 30 mm surface diffuses sound while the dense natural cork behind it absorbs it, delivering a Delta IIC improvement of up to 52 dB. That makes these panels a genuine acoustic treatment for home theatres, offices, bedrooms, and commercial spaces, not simply a feature wall.

Because each diamond is an individual panel, you control the layout: run them in tight tessellation for a full sculpted wall, or scatter them in a custom pattern across a wall or ceiling. The panels are lightweight, so installation is straightforward and DIY-friendly in both residential and commercial settings.
