Ljuds Horizon 150L

Horizon 150L

Ljuds™ Horizon 150L, measuring 1200x2400mm, features precisely grooved horizontal lines that elevates wood wool sound absorption and reduce reverberation. Made from recyclable wood fibres and a cement matrix, its open-pore structure effectively captures sound waves while supporting moisture regulation. With high NRC ratings, fire resistance, and sustainable materials, Horizon 150L is an ideal acoustic panel for offices, residences, and commercial spaces.

Acoustic Performance & Sustainability

Sound Absorption Coefficient

A graph showing absorption coefficient (α) versus 1/3 octave center frequency (Hz) for ISO 354 with 25mm Ljuds. The curve rises from 0.2 at low frequencies to about 1 at higher frequencies near 5000 Hz.

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.
