Interion® By Global Industrial Freestanding Office Partitions provide versatile privacy for cubicles, reception spaces, call centers and more. Panels are made using 1-3/4" thick fabric upholstered panel with an MDF frame and honeycomb core covered with heavy tackable liner for structural strength. Panel trim is finished with self-extinguishing extruded polymer for optimum safety and rigidity. Panels are flame retardant to meet the California 117 flammability standard. Steel T-legs ensure reliable freestanding stability, and make panels easy to adjust and rearrange. Windows are made of translucent polycarbonate material which allows light to come in while still maintaining privacy.
