Term
| what are the differences between platform framing and balloon framing? What are both's advantages and disadvantages? Why has platform framing become the method of choice? |
|
Definition
| ballon framing is constructed using slender, closely spaced wooden members. it also uses full length studs that run continuously from foundation to roof. Eventually, it became apparent that the full length studs were too tall to erect efficiently. Platform framing is constructed by floor, with the platforms in between. Platform framing has become the method of choice because of its short, easily handled lengths of lumber for wall framing |
|
|
Term
| why is little added firestopping required in platform framing? |
|
Definition
| because it's platform breaks up the vertical studs and acts as a firestop |
