Type 5 construction is primarily composed of what material?

Type 5 construction is characterized primarily by the use of wood. This construction type is also known as "wood frame" construction and is commonly seen in residential buildings. The materials used in Type 5 construction typically include light-frame wood, which is advantageous for its availability, cost-effectiveness, and ease of construction. Due to its lightweight structure, this type allows for faster build times and is popular in modern residential developments.

In contrast, the other materials listed contribute to different types of construction. Metal is typically associated with Type 2 construction, which involves non-combustible materials. Concrete is characteristic of Type 3 construction, combining both combustible and non-combustible elements. Brick is generally associated with Type 4 construction, which consists of masonry buildings that promote fire resistance through their durable materials. Understanding these distinctions helps to clarify why wood is the correct answer for Type 5 construction.
