R308.6.1

Section R308.6.1 is titled 'Definitions' and is intended to clarify that the listed terms are defined in Chapter 2, and are subject to section R308.6 and its subsections. One key point in the definitions is that this glazing is 15 degrees or greater from vertical. Glazing installed less than 15 degrees from vertical is not subject to this section. The purpose of this section is to clearly establish the intended applicability of section R308.6.
