Sonex Valueline Panels

SONEX Valueline Panels provide effective acoustic control at an affordable price. The subtle surface pattern on these panels renders them inconspicuous in most settings, making them suitable for a variety of interior settings, including manufacturing facilities, churches and classrooms. SONEX Valueline Panels are made from willtec® foam, which is Class 1 fire-rated for flame spread and smoke density. Willtec natural also meets the corner burn test UL 1715.

SONEX Valueline Panels offer excellent acoustical control across all frequencies with a Noise Reduction Coefficient (NRC) ranging from 0.75 to 1.05. They are especially effective at absorbing excessive sound at the middle frequencies (500 and 1,000 Hz) where unwanted noise and reverberation can interfere with communication.

Panels are available in natural willtec and can be easily mounted to any wall or ceiling surface with pinta’s acoustic water-based adhesive. Separate panels by 1″ from adjacent panels for a more uniform appearance.
