What are two advantages of balloon framing?
The main advantage balloon framing has over platform framing is the increased wind load strength.

How does balloon framing differ from platform framing?
The central difference between balloon and platform framing is that the studs in a balloon frame extend from the foundation to the rafters, whereas in a platform frame, the studs are independent on each storey.
Why is balloon frame construction rarely used?
What are the disadvantages of a balloon frame?
The continuous studs of the balloon frame allow air movement. This has negative consequences not only for heating and cooling, but also fire safety. Fire stops have to be installed in the walls at several locations to impede the flow of fire. The continuous studs also make for a more difficult construction when compared with platform framing.
What are the advantages of a balloon frame roof?
Balloon Frame Advantages. The main advantage balloon framing has over platform framing is the increased wind load strength. The roof structure tied to the sole plate by the continuous studs make balloon framing very popular in hurricane-prone areas.
What is the difference between balloon framing and platform framing?
Balloon framing is one of the earlier wood construction methods. Light frames of wood are constructed around studs that run continuously from top to bottom of a building. The roof is a truss structure that consists of horizontal ceiling joists and sloping rafters. Platform framing is a more modern approach in construction.
