Billo panels install easily into standard suspension systems and can be integrated into flat-panel ceilings to create dramatic focal points. The system consists of 2-foot-by-2-foot preformed, lightweight Lexan infill panels. The panels can be installed either curved upward toward the ceiling or downward toward the floor, permitting customization of each ceiling and a myriad of patterns with just one simple panel shape. The semi-translucent infill panels can also be backlit with fluorescent strip fixtures or integrated with standard lay-in fixtures.
