- The IBC does not prohibit the use of exposed truss bottom chords.
- Since interior grade OSB is allowed on the underside of an exposed truss, it follows that there would not be a more stringent requirement for exposed trusses.
- The USDA Forest Products Laboratory’s Wood Handbook provides the average equilibrium moisture content of wood exposed to the outdoor atmosphere for various cities in the United States.
