What is a key feature of Type 5 construction?

A key feature of Type 5 construction is that it is characterized by the use of all major components made of wood or other combustible materials. This type includes structures that are primarily framed with light wood and can be found in residential buildings and small commercial structures. The framing can include wood studs, joists, and sheathing, making it one of the lighter types of construction available.

Type 5 construction is particularly significant in fire inspections because the use of wood and combustible materials affects the fire behavior and spread. Understanding the materials used in construction is crucial for assessing fire risks and ensuring proper safety measures are implemented.

While other types of construction may include a mix of materials (like masonry and wood) or focus on non-combustible materials (like reinforced concrete), Type 5 is distinctively defined by its reliance on wood or combustible materials throughout its framework, making it essential to recognize this when analyzing building types for fire safety.
