ClearBay Roof Joist System

ClearBay Roof Joist System

Our ClearBay roof joist system is available with either a standard welded bridging or a fully bolted option. It is often the roof joist system of choice to support your CBC standing seam roof. Providing spacious bays of up to 60′, ClearBay provides the ultimate in versatility and open spaces for any number of applications.

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.
