In balloon frame construction, what unique structural feature is present?

In balloon frame construction, the defining feature is that studs extend continuously from the basement to the roof. This means that the vertical framing members are not interrupted by floors, allowing for a continuous vertical space. This design creates a unique structural framework that can lead to specific fire behavior.

Namely, because the studs run all the way up, there is a direct path for heat and flame to travel vertically through the wall cavities, which can allow a fire to spread more quickly between floors compared to other construction methods.

Understanding this helps firefighters anticipate and respond to the unique challenges presented by balloon frame structures during a fire incident because the absence of fire stops can significantly impact fire spread and the effectiveness of firefighting efforts.
