The Sonex® Plano Hanging Baffle provides exceptional sound absorption with virtually unlimited layout and design potential. These baffles install in a similar fashion to hanging T-bar suspended grid systems. For large or small scale construction projects, the Plano Baffle is an excellent alternative to other suspended grid products. Suspended vertically, the baffle offers maximum absorption by having both side of the material exposed to the sound.

By using a standard T-grid, you can create signature designs. Layout baffles in a crosshatch, straight line or other pattern across the width or length of the ceiling. The pre-cut T-slot on the top edge of the baffle allows for suspension using a standard 15/16″ T-grid runner. The T-grid provides mounting points for wire or other hardware and simply slides into the T-slot. The baffle will suspend from the ceiling using installer provided cable and hardware.

For use in retrofit or new construction, Sonex® Plano Hanging Baffles are available in natural white, natural grey or HPC coated colors. HPC coating adds durability and makes cleaning easier. The fire rated acoustical foam core can be shaped with profile designs including convex, concave, wedge and custom contours. These baffles reduce echo and sound reverberation in lobbies, entryways, schools, cafeterias, manufacturing and other large open areas.

With excellent sound control and maximum flexibility, Sonex® Plano Hanging Baffles are an attractive choice for an acoustic ceiling treatment.

Our exclusive water based HPC formulation improves durability and protects the acoustical foam from dust and dirt, allowing the surface to be cleaned using a damp cloth. The HPC coating is especially appropriate for use high-traffic areas. HPC Premium extends the HPC coating further by offering a line of brilliant colors from which to choose.
