What type of framing allows fire to travel quickly through chases from one floor to another?

Balloon framing is the correct answer because it involves continuous vertical studs that extend from the foundation to the roof. This design creates open chases or channels within the walls, which can allow fire to travel more easily from one floor to another. When a fire ignites on one level, the flame and heat can easily move up these vertical spaces, providing a direct path for the fire to spread rapidly throughout the structure.

In contrast, platform framing, which is more common in modern construction, utilizes horizontal framing and separates each floor with fire-blocking elements, which can help to slow the spread of fire. King-post and scissor framing are types of truss designs primarily used for roof structures and do not contribute significantly to the vertical spread of fire in the same way that balloon framing does. Understanding these framing methods helps highlight the importance of fire safety and building codes in residential construction.
