What defines Type 5 Wood Frame construction?

Type 5 Wood Frame construction is characterized by the use of exterior load-bearing walls that are made entirely from wood. This classification refers to structures where the framing, walls, and roof can all be constructed with wood materials, which is a common approach in residential building. The design is typically lighter and allows for flexibility in construction. Additionally, this type of construction does not incorporate heavy materials like steel or concrete as load-bearing elements, distinguishing it from other building types that use more robust materials.

The use of wood allows for efficient construction and is often associated with lower costs, but it also means that the fire resistance might be lower compared to heavier construction types. Thus, understanding the characteristics of Type 5 helps fire officers assess the potential risks and fire behavior associated with such buildings.
