Which type of construction is known for using wood frame as its main component?

The type of construction recognized for primarily utilizing wood frame as its main component is Type 5 construction. This construction type primarily involves the use of lightweight wood framing and is often referred to as “wood frame” construction. It is characterized by a structural system that consists of wood studs, joists, and rafters, which provide the framework for residential buildings and smaller commercial structures.

Type 5 construction is generally less fire-resistant compared to other construction types, as it uses materials that can easily ignite and contribute to the spread of fire. This characteristic impacts the fire safety regulations and building codes that are applicable to structures of this nature. In addition, the relatively simple assembly and lower material costs make Type 5 construction a popular choice for many builders.

Type 3, Type 4, and Type 2 constructions each have different materials and design characteristics, focusing on masonry, heavier timber, or non-combustible materials, respectively, which distinguishes them from Type 5. Understanding these classifications is crucial for fire inspectors as they assess fire risks and enforce building safety regulations.
