In which construction type are there direct vertical channels in the exterior walls?

Balloon frame construction is characterized by long, continuous framing members that extend from the foundation to the roof without interruption, creating direct vertical channels in the exterior walls. This design allows for openings, such as windows and doors, to be easily accommodated, making it a popular choice in residential construction.

In balloon frame structures, the wall studs run the entire height of the building, providing a pathway for fire and smoke to travel vertically between floors. This can be a significant concern in fire situations, as the direct vertical channels can facilitate the rapid spread of flame and smoke throughout the structure.

Understanding the characteristics of balloon frame construction is essential for firefighters, as it influences tactics used during fire suppression and ventilation. The presence of these vertical channels also underscores the importance of assessing fire behavior and potential hazards within this type of building.
