What type of building construction is known as lightweight construction?

Lightweight construction is primarily associated with Type V construction. This type involves materials that are less dense and often utilizes wood truss and wood-frame components. Lightweight construction techniques are widespread in residential buildings due to their cost-effectiveness and efficiency in material use.

Unlike heavier construction types that incorporate more robust materials like concrete or steel (as seen in Types I, II, and III), Type V construction focuses on the use of materials that are lighter and more susceptible to fire. This distinction is vital for firefighters and safety officials, as Type V structures present unique challenges, especially regarding fire behavior and structural integrity under heat exposure. Understanding the characteristics of Type V construction is essential for effective risk assessment and response strategies during firefighting operations.
