Ljuds Vertical 75L

Vertical 75L

Ljuds™ Vertical 75L, measuring 1200x2400mm, is designed with deep vertical grooves to optimize sound absorption and minimize reverberation. Its composition of recyclable wood fibres and cement allows for effective noise control while helping to regulate indoor humidity. Durable and fire-resistant, it is well-suited for large-scale applications.

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.

Frequently Asked Questions

The Vertical 75L is a large-format wood wool acoustic panel (1200 × 2400 mm) designed with deep vertical grooves that not only enhance visual height in interiors but also help optimize sound absorption and reduce reverberation more effectively than smaller units.

Its open-pore structure made from recyclable wood fibres and cement allows sound waves to penetrate and be absorbed rather than reflected. This reduces echoes and creates a more comfortable acoustic environment, especially in larger spaces.

Yes — the extra-tall dimensions and durable build make Vertical 75L ideal for high-ceiling commercial settings, auditoriums, offices, and hospitality venues where enhanced sound control is needed over expansive surfaces.

Vertical 75L is made from eco-friendly, recyclable materials that help reduce environmental impact. It is also fire-resistant and moisture-regulating, contributing to safer and healthier indoor environments.

Yes — according to ISO 354 testing, this panel demonstrates high sound absorption across mid-to-high frequencies, making it effective at controlling reverberation and improving clarity in speech-focused spaces.
