Quick determination to whether a structure is ballon frame is…?
remove a baseboard on an EXTERIOR WALL AND CHECK FOR THE PRESENCE OF A SOLE PLATE, if none if found, treat as BALLOON CONSTRUCTION
In BALLOON CONSTRUCTION, ….
fires originating in the cellar can easily extend to that attic via the exterior wall channels created by this continuos studding, this type of concealed fire extension will commonly extend to the attic space, while bypassing intermediate floors
Platform construction..?
exterior wall studs extend only from the floor to the ceiling of each individual floor…they are capped at the ceiling level of each floor with a 2x4 called a TOP PLATE…this construction feature acts effectively as a fire stop and limits or restricts vertical extension via the exterior walls
What should be a concern to FF’s operating on upper floors..?
