LR CLEANROOM GRIDS

LIGHT DUTY, GASKETED CEILING SYSTEMS

Cleanroom 1.5 Inch Ceiling Grid Ceiling

Gordon Cleanroom products LR-15 ceiling system is designed primarily for use in pharmaceutical, hospital and food service cleanroom applications. Extruded aluminum grid members have a ¼” upturned flange to provide a cleanable edge that also conceals the gasket. Blank panels, filters or other ceiling components first contact the gasket to create an airtight seal prior to settling on the tee flange. Grid components are fabricated of extruded aluminum for maximum structural integrity and corrosion resistance, even in harsh environments. Aluminum assembly clips simplify installation and require no special tools to attach grid components. Optional hold-down clips are available to secure blank panels in the grid.
