What is the most common building material used in North America according to fire protection standards?

Wood is the most common building material used in North America, largely due to its availability, cost-effectiveness, and the ease with which it can be worked into various structures. Fire protection standards take into account the distinct characteristics of different materials, and wood is prevalent in residential construction, from framing to flooring and cabinetry. This widespread use means fire protection strategies are heavily focused on addressing the fire risks associated with wood structures.

While concrete, steel, and brick are all important materials in construction and have their own fire-resistant properties, they are not as commonly used in the construction of smaller residential buildings, which are more frequently built using wood. The preference for wood in these settings necessitates an understanding of its fire behavior, including how it burns and the implications for fire prevention and suppression measures. This knowledge is vital for fire protection professionals to effectively mitigate fire risks in predominantly wood-constructed environments.
