balloon framing



  • A system of framing a building in which all vertical structural elements of the bearing walls and partitions consist of single pieces extending from the top of the soleplate to the roofplate and to which all floor joists are fastened. See also framing.
  • A style of wood framing in which the vertical structural members (the posts and studs) are single, continuous pieces from sill to roof plate. The intermediate floor joists are supported by ledger boards spiked to or let into the studs. The elimination of cross grains in the studding reduces differential shrinkage. See also balloon frame.
