Two methods are used in standard wood house or “stick” framing—balloon or platform—and both have advantages and disadvantages. Balloon framing is sometimes used with two-story buildings. In balloon framing the studs extend as one, from the sill to the top plate of the second story. The second story floor joists are supported by a ribbon board set into the studs. This type of construction is the most difficult, but does provide unobstructed openings between the floors allowing for easy installation of utilities without notching and cutting openings. Fire stops must, however, be installed at the second story floor level between the studs.
Platform framing can be used for either single or two-story and is the easier and most common method of construction. Fire stops are automatically created with this type of construction. Constructing a single-story is the easiest, a two-story or split level is harder. Platform framing is easier than balloon framing because you can construct and erect the second story walls on the second story floors.
