In a balloon frame there are no braces or girts, and the intermediate studs FFF, Fig. 91, are carried straight up from the sill H to the plate K, with a light horizontal piece J, called a "ribbon" or "ledger board," set into them at each floor level to support the floor joists. This frame depends mainly upon the boarding for its stiffness, but sometimes light diagonal braces are set into the studs at each corner to prevent distortion. The methods by which all these pieces are framed together will be explained in detail under the proper headings.
