The Sonex® Contour Ceiling Tile combines sound absorption with an eye-pleasing design for applications with existing T-bar suspended grid systems. These ceiling tiles are available in two thicknesses to achieve the desired amount of absorption for your project. Constructed with Class 1 fire-rated acoustical foam and a sag-resistant backer board, the Sonex® Contour Ceiling Tile meets public building code requirements. These ceiling tiles easily install into existing standard 2? x 2? suspended ceiling grid systems. Cross tees may be added when used in a 2? x 4? grid. Sonex® Contour Ceiling Tiles add sound absorption to any grid system lowering reverberation and echo while improving speech intelligibility.
