Ceiling tiles and hanging hardware are used together to create suspended ceilings for indoor spaces. Ceiling tiles install into a grid system creating a dropped ceiling with a plenum space above. Ceiling tiles are available to help reduce sound for privacy, resist sagging and mold in high-humidity areas, work with ISO cleanroom-rated systems, create sealed systems for isolation rooms, and help prevent access to restricted areas. Hanging hardware is installed into existing ceiling structures and creates a grid at a set height above the ground. Construction and maintenance particle containment units temporarily create sealed work areas that greatly reduce the spread of dust and debris from work areas.
