Step 2) Glass Size Formulas
For captured glazing variations, the glass size formula is DLO + 7/8". For structural
glaze systems the glass size formula is DLO + 1 1/2”. The glass size formula from
captured mullion to SSG mullion is DLO + 1 3/16". From SSG mullion to SSG mullion
the glass size formula is DLO + 1 1/2". Captured mullions have a glass bite of 7/16".
SSG mullions have a glass bite of 3/4". 90° SSG corners use offset glass with the
interior glass size and the exterior glass size being different (see Figure 94). Refer to
Figures 93, 94, and 95 below.

Customer / Installer Note:
EFCO setting blocks are typically 4" in length with
different depths. If the glazing infill is "NOT BY EFCO"
and glazing sizes are larger than 40 square feet, then
the glazing details must be reviewed by the glazing
manufacturer for proper setting block size.
