Ljuds Diagonal 1200

Diagonal 1200

Ljuds™ Diagonal 1200 showcases precisely grooved lines in a 600x1200mm size, effectively absorbing sound and minimizing reverberation. Constructed from recyclable wood fibres and a cement matrix, its open-pore structure captures sound waves while maintaining moisture balance. With excellent NRC ratings and fire resistance, Diagonal 1200 panels provide a long-lasting and architecturally distinct acoustic solution for offices, residences, and commercial environments.

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.
