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.
