What is an example of Type 5 construction?

Type 5 construction is characterized by its use of wood as the primary structural material, typically involving a frame system that may include wood studs, joists, and rafters. This construction type is best exemplified by small family homes, which are often built using light-frame wood construction methods. These structures are generally limited in height and area, making them distinct from larger, more complex buildings.

Small family homes are designed with simplicity and affordability in mind, utilizing readily available wood materials. In contrast, commercial buildings and high-rise apartment buildings often utilize materials such as concrete and steel, which are associated with Type 1 and Type 2 construction. Heavy timber buildings, while they do incorporate wood, generally fall under Type 4 construction due to the size and treatment of the timber.

This distinction in building types helps firefighters understand the inherent risks and fire behavior associated with different constructions, especially in terms of how quickly the materials can ignite and the potential for structural failure during a fire. Understanding these classifications is crucial for effective firefighting tactics and safety measures tailored to specific building types.
