Diagonal 600

Ljuds™ Diagonal 600 features finely grooved lines in a 600x600mm size, designed to improve sound absorption and reduce reverberation. Made from recyclable wood fibers and a cement matrix, its porous structure efficiently captures sound waves while regulating moisture. With high NRC ratings and fire resistance, Diagonal 600 panels offer a durable and visually dynamic acoustic solution for offices, residences, and commercial spaces.

Acoustic Performance & Sustainability

Sound Absorption Coefficient

Line graph showing absorption coefficient (α) rising from about 0.2 at 50 Hz to a peak around 1.0 near 2500 Hz, then slightly dropping at 5000 Hz. X-axis: 1/3 Octave Center Frequency (Hz). Y-axis: Absorption Coefficient (α).

Ljuds™ wood wool acoustic panels undergo ISO 354 testing to measure sound absorption across frequencies. The results show high efficiency, especially in the mid-to-high range, ensuring effective reverberation control.

Frequently Asked Questions

Diagonal 600 are 600 × 600 mm wood wool acoustic panels featuring finely grooved diagonal lines that help absorb sound and reduce reverberation in interior spaces, making them ideal for offices, residences, hospitality venues, and commercial environments where better acoustics are needed.

The diagonal grooves create a dynamic geometric texture that not only enhances visual interest but also increases surface area for sound interaction, improving sound absorption and reverberation control while adding architectural character to walls or ceilings.

Diagonal 600 panels consist of recyclable wood fibres bound in a cement matrix, resulting in a porous structure that effectively captures sound waves, regulates moisture, and supports sustainable interior design with eco-friendly materials.

Yes — wood wool panels naturally regulate moisture thanks to their open-pore structure, helping maintain more stable indoor humidity and contributing positively to the acoustic comfort and environmental quality of a space.

Yes — these panels demonstrate robust acoustic performance with high NRC values across a range of frequencies and are engineered for durability. The wood wool and cement composition also supports fire resistance and long-lasting performance suitable for demanding interior applications.
