Safety glazing label required. SPEC WRITER NOTE: Retain below if required for exterior glazing in hurricane high velocity wind zones; coordinate glass selection and interlayer thickness required based upon tested assemblies. 7. Windborne debris-resistant glazing unit required. 3.17 INSULATING GLASS SCHEDULE: SPEC WRITER NOTES: Use this schedule for applications where there are no force protection or other physical safety protection requirements that stipulate laminated glass lites for exterior openings. For exterior openings requiring laminated glass indoor lites, use INSULATING LAMINATED GLASS SCHEDULE below. Low emissivity coating should be on the air space surface of the inner pane of glass (the number 3 surface) in heating-dominated buildings, and on the number 2 surface (inside surface of the exterior pane) in coolingdominated buildings.
