SONEX Junior Panels feature a modified anechoic wedge design for cost-effective, yet impressive sound control. The unique geometric shape of the surface pattern on these panels provides optimum deflection of sound waves, making them an excellent choice for recording and broadcast studios. These versatile panels can also be used in listening rooms, restaurants, production areas and other locations where sound absorption is critically important. Panels offer excellent acoustical control across all frequencies with a Noise Reduction Coefficient (NRC) ranging from 0.75 to 0.80.
SONEX Junior Panels are available in natural willtec®. The panels are also offered in colortec (the entire thickness of the foam panel is dyed a deep charcoal) and colortec premium (colortec with a more uniform surface color). These panels are especially appropriate for high-traffic areas.
Regardless of the finish option, pinta’s exclusive willtec is Class 1 fire-rated, according to ASTM E 84 for flame spread and smoke density. willtec natural and colortec meet the corner burn test UL 1715.
These panels can easily be mounted to any wall or ceiling surface with pinta’s acouSTIC water- based adhesive.
