I'll assume you mean literally, as opposed to some metaphorical phrase like "glass ceiling", and that furthermore you know what a ceiling is and are just curious about the "gilded."
Gilded means "covered with gold". In the case of a ceiling, it would be very thin gold foil applied to the ceiling.
To add to your answer, you are correct but the term was mostly used with regard to ornate plaster moulding in the crown area and around central disks where gas lines passed through for lighting.
The wooden crown moulding would be cut to lengths easy to handle. Each piece is then covered with mesh hemp or linen fabric that is very loose to prevent cracking and to allow easy removal from the mould. It is then covered in plaster of Paris and placed into the mould ( hence the term moulding)
Afterward it would harden or "set up". Once set up, the moulding would be removed from the mould and then guilded with gold leaf.
