Why is balloon framing no longer used? But wide spaces between studs create safety hazards. “This framing method was used because of its ease of construction and availability of good lumber,” Stack said. “The method allowed many urban workers in America to build their own homes.” Balloon framing is no longer used today, Stack said.
Similarly, What are the advantages of balloon framing?
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. Balloon frame structures also have less settling than platform framing as a result of shrinkage.
What is balloon framing used for?
In balloon framing, the studs (vertical members) extend the full height of the building (usually two stories) from foundation plate to rafter plate, as contrasted with platform framing, in which each floor is framed separately. Balloon framing is used primarily in Scandinavia and in the United States.
What does balloon framing look like?

What are the drawbacks of balloon framing?
The two major cons of balloon framing are that long studs are less efficient to erect then shorter ones used in platform framing and the continuous spaces between studs act as chimneys during a fire, unless closed off with a fire-stop.
How are second floor joists supported when using balloon frame construction?
The floor joists for the second floor were usually supported on a ledger or ribbon that was let into the studs. Balloon-framing was replaced by platform-framing (today’s building method of choice) when the trees that produced the long studs became scarce. … Assembly of the balloon frame was sort of like weaving a basket.
Is balloon framing stronger?
Balloon framed houses use some very long pieces of lumber. … Though not as strong and imposing as a timber frame, balloon frames were eventually regarded as a more than acceptable way to build a house. And from the 1890s until the 1930s it was the most common form of construction in the country.
Are there load bearing walls in balloon framing?
The balloon frame, essentially, eliminates the heavy timber frame. Instead, the floor members sit on the walls directly, which become load bearing elements.
Where do you find balloon frame construction?

How do you support a balloon frame?
How is the second floor of a house supported?
With a second story, you have to build it with larger lumber to support the second floor. … While first-floor supports are needed to account for the additional weight of a second floor, the walls are pretty much the same as those of a single-story home.
Why is platform framing used more extensively than balloon framing?
Why has platform framing become the method of choice. … Balloon framing has less vertical shrinkage from drying out of the wood, while platform framing is easier and safer to erect, uses shorter lengths of lumber for studs, and is automatically firestopped, for which reasons it has become the method of choice.
Who invented balloon framing?
Chicago architect John M. Van Osdel attributed the invention to Chicago carpenter George W. Snow in 1832. The Chicago History Museum and other scholars point out that Virginia carpenters in the 17th century — facing similar pressures to build fast — employed similar techniques.
What’s the difference between balloon framing and 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.
What is the difference between platform framing and balloon framing?
What are the differences between balloon framing and platform framing? … 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.
What could be considered an advantage of balloon frame construction compared with platform frame construction?
Large or vaulted windows are also more workable with the balloon technique than platform framing. The technique creates a structure with a higher resilience due to the longer wall frames that are used.
