Diamond Grey

Diamond Grey Acoustic Cork Wall Panels

Sculpted gray diamonds in a deep 1 3/16 in. (30 mm) relief that quiet a room as dramatically as they style it.

Diamond Grey is a three-dimensional wall panel molded from agglomerated cork using compression molding. Each piece is a faceted diamond in a soft gray tone, with diagonals of 16 11/16 in. (424 mm) and 9 41/64 in. (245 mm), so a wall builds up into a repeating geometric relief that catches light differently from every angle.

At 1 3/16 in. (30 mm), this is the thickest profile in the 3D panel range, and that depth is what does the acoustic work. The faceted surface scatters sound instead of bouncing it straight back, and the dense cork body absorbs it, delivering a Delta IIC rating of up to 52 dB. The same cellular structure that soaks up noise also insulates, helping keep interiors warm and energy efficient.

The panels are lightweight and designed for hassle-free installation on both walls and ceilings, which makes them a practical fit for home offices, media rooms, bedrooms, and light commercial spaces such as studios and meeting rooms. Because cork is natural, biodegradable, and hypoallergenic, you get the acoustic upgrade without compromising indoor air quality.

Why this wall

• Soundproofing plus diffusion: the 3D faceted surface diffuses sound while the cork absorbs it, with a Delta IIC rating of up to 52 dB.
• Deep 1 3/16 in. (30 mm) profile: the thickest option in the 3D panel range, for maximum relief and acoustic mass.
• Diamond geometry: diagonals of 16 11/16 in. (424 mm) and 9 41/64 in. (245 mm) with a 9 41/64 in. (245 mm) side length, allowing endless arrangement patterns.
• Thermal insulation built in: natural cork helps keep interiors warm and energy efficient.
• Hypoallergenic and sustainable: made from natural, biodegradable, renewable cork, safe for all interior spaces.
• Walls and ceilings: rated for residential and light commercial use, with a 5 year warranty against manufacturing defects.
• Fire-retardant option: panels can be fire-retardant impregnated and certified C-s2, d0 to EN 13501-1:2018.

Important product note

These panels are supplied in their natural agglomerated cork form as standard. If your project requires a certified fire rating, the panels can be ordered fire-retardant impregnated and certified C-s2, d0 to EN 13501-1:2018. This 1 3/16 in. (30 mm) Diamond Grey panel sits at the thick end of the 3D collection, which ranges from 13/64 in. (5 mm) up to 1 3/16 in. (30 mm): choose the thicker profiles when acoustic performance is the priority.
