Frequently Asked Questions
Ljuds™ Prism panels are wood wool acoustic panels with a dynamic, multi-faceted design that enhances sound absorption and reduces reverberation. They combine visual interest with functional acoustic performance for interior spaces such as offices, residences and commercial venues. Prism panels are crafted from wood fibres bound with a cement matrix for strength and durability.
The porous structure of Prism wood wool panels allows sound waves to enter and be absorbed rather than reflected back into the room. This lowers echo and reverberation, improving speech clarity and overall acoustic comfort. The design and material work together to create a balanced acoustic environment.
Ljuds™ Prism panels have been tested under ISO 354 acoustic standards and deliver a Noise Reduction Coefficient (NRC) around 0.55. This indicates strong sound absorption capabilities suited to mid-to-high frequency ranges commonly found in offices, classrooms and public spaces.
Yes. Prism panels are made from recyclable wood fibres with a low-emission cement matrix, contributing to eco-friendly design goals. They meet environmental standards such as EN 13986 (E1) for low VOCs and are fire classified to EN 13501-1 Class B s1 d0 for safe installation in various indoor environments.
Prism panels are versatile and suitable for both walls and ceilings. They work well in offices, hospitality spaces, auditoriums, residences and other settings where echo reduction, sound absorption and modern design are priorities. Their geometric form adds surface texture while managing interior acoustics effectively.
