    opaque portion of a door -temperature rise

    When addressing temperature rise for fire doors, the temperature rise limit applies to the "opaque portion" of the door. My questions: 1. Is a fire door in a fire wall allowed to have glazing? 2. Is there a temperature rise restriction on the glazing portion of a fire door in a fire wall?

    Glazing in Fire Wall

    We have storefront within a fire wall and as I understand it, fire-resistance-rated glazing assemblies can be utilized within a fire wall. That being said, can we use normal glazing and provide a vertical/side acting fire shutter instead, or does the glazing need to be rated regardless?

    Egress Through Fire Wall Used Fir Area Separation

    The code allows you to use a fire wall to consider a portion of the building as a separate building for building area calculations. When this is done, are you allowed to have egress through the fire wall to share an exit or does each separate "building" need to have the required 2 exits?
