Wall Secondary Framing

CBC offers three standard girt offsets: bypass, flush, and inset.
A bypass condition greatly reduces material thickness and creates a stiffer system, while reducing cost. There is also no compression to blanket insulation. Flush and inset girt systems cannot span continuously past the columns, resulting in a heavier girt system and additional material. The benefit is columns are set back into the girt cavity, creating greater clearance between columns.
