What type of construction is characterized by wood-frame elements such as exterior walls and floors that enable fire extension?

Type V construction is characterized by the use of wood-frame elements, including exterior walls and floors, which are particularly susceptible to fire extension. This type of construction typically utilizes combustible materials like wood, which can ignite quickly and allow fire to spread rapidly both vertically and horizontally through the structure.

In Type V buildings, the lack of fire-resistive materials and structures means that once a fire starts, it can move from one area to another with relative ease, posing significant risks to the overall integrity of the building and safety of occupants. This construction type often includes single-family homes and smaller buildings where wood is a primary material due to its availability and cost-effectiveness.

Understanding the attributes of Type V construction is critical for fire prevention and safety measures, as well as for effective firefighting strategies, given the increased risk of rapid fire spread compared to other construction types.
