The details that follow are standard details that depict proper detailing for cold-formed steel framed exterior walls. The concept is to illustrate water tightness independent of the exterior finish. For example, brick veneer finish, with proper attachments, flashing, weeps, and ledgers can be used. These details are adapted from the concepts provided by the Foam Sheathing Committee (FSC). The intent is to serve as a guide. Final approval of detailing for a specific construction project is the right and responsibility of the Architect of Record.
