Ceiling
A ceiling is a part of one's home that separates the roof from the room. A ceiling can be created above any room. Ceilings were first introduced in The Sims 2: Apartment Life EP. Ceilings were also automatically created in The Sims 3, as this feature carried over. In Apartment Life, one can change the ceiling to be whatever pattern of flooring they wish. In Seasons, ceilings are crucial to keep the elements out.
