|
Term
| UBC and IBC limits on the amount and type of glass in one hour rated corridors. |
|
Definition
| UBC requires that the glazed openings must be protected by 1/4 inch wire glass installed in steel frames or by approved fire-rated glazing. The maximum glazed area connot exceed 25% of the area of the corridor wall of the room that it is separating from the corridor. Special fire-protection rated glazing is not subject to this 25% limitation because it is tested as a wall assembly, not as an opening assembly. |
