Diagonal Squares - Wood Wool Acoustic Panel

The Diagonal Squares wood wool acoustic panel combines geometric precision with natural texture to create a distinctive architectural surface. Crafted from mineralised fir wood wool bound with white Portland cement, these panels provide excellent sound absorption and thermal insulation. The finely detailed 2 mm strands form a diagonal square pattern that gives depth and movement to the surface, making it ideal for sophisticated modern interiors.

How It Works

The open-cell structure of the mineralised wood wool efficiently absorbs airborne sound waves by converting them into heat within the material. The cement binder increases density and durability, maintaining the panel’s structural integrity over time. When installed with an air cavity or mineral wool backing, the panels achieve certified absorption coefficients of up to αw 0.95, effectively reducing reverberation in both large and compact spaces.

Key Benefits

• Acoustic absorption up to αw 0.95 for balanced room acoustics
• Fire classification Euroclass B-s1,d0 for safe indoor use
• Durable and resistant to impact, humidity, and temperature changes
• Produced from eco-certified, low-emission materials (ANAB-ICEA, Natureplus, PEFC™, FSC®)
• Multiple thickness and size options for flexible acoustic design
• Distinct diagonal square texture adds refined visual structure
• Suitable for use on walls, ceilings, and suspended systems

Installation Overview

The Diagonal Squares panels can be installed using direct adhesive application, mechanical fixings, or suspended framing systems. Mounting the panels with a backing layer or air gap enhances their acoustic performance. The lightweight construction allows easy handling, alignment, and cutting, ensuring seamless design continuity across walls or ceilings. Installation is quick and adaptable to both new and existing interiors.
