Sonex Pyramid Panels outstanding acoustic control across all frequencies with Noise Reduction Coefficient (NRC) ranging from 0.75 to 1.05. The unique geometric design of these panels dramatically increases the panels’ surface area, providing much more acoustic control than flat surfaces. SONEX Pyramid Panels are made from pinta’s willtec® foam, which is Class 1 fire-rated according to ASTM E 84 for flame spread and smoke density. willtec natural also meets the corner burn test UL 1715.
SONEX Pyramid Panels, available in natural willtec, can be easily mounted to any wall or ceiling surface with pinta’s acoustic water-based adhesive. Once installed, the 24″ x 24″ panels align to make an attractive, seamless pattern
