- The Western Lumber Grading Rules permit combinations of like-named U.S. and Canadian species groups, which allows mills that have access to logs from the U.S. and Canada to mix them during production.
- The most common combinations are Douglas Fir-Larch, Hem-Fir and Spruce-Pine-Fir.
- The applicable design values for a given U.S. and Canadian species group combination that component manufacturers should use in their software are the lower of the two individual country values for each design value category (see Table 2 on page 76).

- The requirements for fire generally take precedence over those for sound.
- What is good for fire performance may not be good for sound performance. The reverse is also true.
- Determining sound ratings is a building designer or specialty engineering re-sponsibility, so be sure not to take on any design work responsibility that falls beyond your scope of work.
