There are generally two types of Ceiling styles and many possibilities for custom ceilings. Basic styles are grid ceiling or solid core island ceiling. Ceilings generally do not touch the cab walls, allowing a couple inches of clearance for air to circulate to the cab's exhaust fan. They are also suspended below the cab dome/canopy by two or more inches in order to allow for light fixtures and air flow. All ceilings must have a removable section in order for rescuers to gain access to passengers through the dome top emergency exit in the event of an emergency.
Grid Ceiling is a lightweight aluminum t-grid layout with openings that receive lay-in panels or light diffusers. If light diffusers are used then fluorescent or LED light strips are installed to illuminate the cab through the light diffusers.
Solid Core Island Ceiling has a solid core laminated with a finished surface such as plastic laminate, stainless steel or bronze. Finishes are installed in a manner to conceal the removable section which will align with the existing dome top emergency exit. Recessed down lights are then installed in the ceiling in a quantity to adequately illuminate the elevator according to the required lighting level.
