What does Type 3 construction primarily consist of?

Type 3 construction, also known as "Ordinary Construction," primarily consists of non-combustible exterior walls and wooden interior components. This type of construction typically features masonry or concrete materials for the building’s outer shell, which provides a degree of fire resistance, while the interior framing is composed of wood. This combination allows for some enhanced safety regarding fire spread from the exterior, but the interior wooden components can still pose a significant fire risk. Understanding the structure of Type 3 construction is essential for firefighting, as it dictates how a fire may behave within such a building and informs strategies for effective fire control and prevention.
