Diagonal Lines - Wood Wool Acoustic Panel

The Diagonal Lines wood wool acoustic panel brings a refined architectural finish to acoustic design. Made from mineralised fir wood wool bonded with white Portland cement, it provides exceptional sound absorption and thermal insulation while maintaining a natural, textured aesthetic. The 2 mm wood wool strands form a diagonal pattern that gives the surface a distinctive sense of movement and depth, ideal for modern and high-end interiors.

How It Works

Each panel combines the mass and porosity of mineralised wood wool to absorb airborne sound waves effectively. The open texture slows and diffuses sound energy, while the cement binder adds density and stability. Installed with or without an air cavity or mineral wool backing, the panels can reach certified absorption coefficients of up to αw 0.95, depending on the configuration. This performance reduces reverberation and improves speech intelligibility in large or acoustically challenging spaces.

Key Benefits

• Certified sound absorption with αw up to 0.95
• Complies with EN 13168 and EN 13964 standards
• Fire reaction classification: Euroclass B-s1,d0
• Resistant to moisture, impact, and temperature variations
• Produced with eco-certified materials (ANAB-ICEA, Natureplus, PEFC™, FSC®)
• Elegant diagonal texture enhances architectural aesthetics
• Suitable for walls, ceilings, and suspended systems

Installation Overview

Diagonal Lines panels can be installed using adhesive bonding, mechanical fasteners, or suspended ceiling grids. They can also be mounted on battens with mineral wool backing to maximise absorption. The lightweight boards are easy to cut and fit, ensuring a precise finish for both new construction and renovation projects. Panels are suitable for direct wall application, ceiling rafts, and baffle installations.
