The main difference between platform and balloon framing is at the floor lines. The balloon wall studs extend from the sill of the first story all the way to the top plate or end rafter of the second story. The platform-framed wall, on the other hand, is independent for each floor.
In balloon framing, the studs run in one piece from the sill to the rafter plate, whereas in platform framing, the studs are interrupted by floor platforms.
Also Know, what is a platform framing? Platform framing (also known as western framing) is the most common framing method for residential construction where each floor of a pole barn or conventional building is framed independently by nailing the horizontal framing member to the top of the wall studs.
Beside this, what is balloon style framing?

What are parallel wooden beams that support flooring called?
Floor Joists A floor’s framework is made up mostly of wooden joists that run parallel to one another at regular intervals. Floor joists are typically 2 by 8s, 2 by 10s, or 2 by 12s; ceiling joists are usually 2 by 6s or sometimes 2 by 4s if it is an older home.
