Sonofonic Acoustic Ceiling Panels

Sonofonic Acoustic Ceiling Panels are engineered to absorb sound and control reverberation in large interior spaces. Unlike traditional fabric-wrapped panels, Sonofonic panels feature a painted acoustic finish, offering a clean, modern appearance that integrates well with commercial or educational ceiling designs.

These panels are designed for both acoustic performance and visual simplicity, making them suitable for lecture theatres, open-plan offices, classrooms, and public buildings. Available in custom sizes and colours, Sonofonic panels can be installed in ceiling grids or fixed directly to ceilings.

Performance and Applications

So Why Sonofonic?

High Acoustic Performance

Sonofonic Acoustic Ceiling Panels – Functional, Clean, and Quiet

Sonofonic Acoustic Ceiling Panels are designed to reduce noise and improve speech clarity in interior environments where echo and reverberation are an issue. These panels help create quieter, more effective spaces for work, learning, and communication.

Constructed with a lightweight, fire-resistant core, each panel is finished in a cleanable, lightly textured painted surface. This combination offers acoustic performance with a durable, low-maintenance design suitable for a wide range of interiors.

Sonofonic Panels are available in various edge profiles to fit standard suspended ceiling grid systems. They are often specified for boardrooms, open-plan offices, lecture theatres, and hospitality venues where sound control and aesthetic integration are essential.

Available Surfaces

Tonasorbâ„¢ Surface Finish for Sonofonic Panels

Sonofonic Ceiling Panels are finished with Tonasorb™ — a durable coating designed to provide both surface protection and acoustic transparency. Available in three grades — 700 Microporous, 600 Embossed, and S101 Textile — each offers a unique textured look and contributes to the panel’s acoustic performance.

The Tonasorb™ finish delivers a cleanable, impact-resistant surface while allowing sound waves to pass through to the acoustic core. This helps reduce reverberation without compromising the panel’s appearance or durability.

Tonasorbâ„¢ also offers high light reflectance, supporting natural daylighting and artificial lighting efficiency. The finish is factory-applied to the face and all exposed edges, while the rear of the panel is sealed with a non-woven glass fibre scrim for added protection.
