What characterizes a smooth ceiling?

A smooth ceiling is characterized by being a continuous surface that is free from significant irregularities. This means that the ceiling has a flat and even finish, contributing to a clean and polished appearance. Smooth ceilings are often preferred in various construction and design contexts because they can enhance lighting effects and contribute to a more spacious and airy feel in a room.

In contrast, ceilings that are rough-textured, have various patterns or indentations, or consist of a series of panels do not meet the definition of a smooth ceiling. These characteristics can introduce visual complexity or texture that distracts from the simplicity and uniformity that define a smooth ceiling.
