Advanced Framing

The following are pictures of advanced framing techniques. Note: Advanced framing is not required by code, but is a great practice that reduces lumber use and maximizes a structure's thermal efficiency. 

There are several framing options that allow for insulated headers.

Two-stud corners decrease lumber use and allow more room for insulation.
