Lesson summary

This lesson focuses on ceilings, an essential component of the superstructure of any building. In our daily lives, we often look up and see a finished surface above our heads in our rooms, classrooms, and places of worship. This is the ceiling. It is more than just a cover; it plays crucial roles in safety, comfort, and aesthetics. Understanding the functions, materials, and types of ceilings is fundamental for any student of building construction. This knowledge is practical, as it helps in making informed decisions during building projects, whether it's a family home in Kumasi, an office block in Accra, or a school in Tamale.

Lesson notes

A. What is a Ceiling?

A ceiling is the overhead interior surface that covers the upper limits of a room. It is the surface you see when you look up inside a building.

It is important to distinguish a ceiling from a roof. The roof is the external, top covering of a building which protects it from the weather (rain, sun). The ceiling is the internal surface below the roof structure.

The Ceiling as a Component of the Superstructure Recall that the superstructure is the part of a building that is above the ground level. The ceiling is a key component of the superstructure. It is generally a non-load-bearing element, meaning it does not carry the weight of the structure above it. Its main purpose is to provide a finish and perform other functions we will discuss below. The ceiling is typically attached to the floor joists of the floor above or the roof trusses. B. Functions of a Ceiling
