What weakness is associated with Type 2 construction?

Type 2 construction is characterized by a combination of non-combustible and limited-combustible materials, which can create a unique set of challenges during a fire. One significant weakness associated with Type 2 construction is the risk of outside and inside fire spread. This can occur due to the materials used in the exterior and interior walls, which, while representative of a lower fire risk than combustible types, may still allow flames or heat to transfer through walls or openings including windows and doors.

In Type 2 construction, insulation and building assemblies can sometimes contribute to fire spread if the flames breach the exterior. This can jeopardize both the interior spaces and the exterior context, as fires can easily transition from outside to inside, especially in cases where combustion can occur due to materials on the exterior. Such spread can complicate the firefighting process and can put both occupants and responders at a higher risk.

This understanding highlights why addressing fire spread in Type 2 buildings is crucial for fire safety and prevention strategies.
