Fire rated doors


You remove the old door and jambs and install a door that is fire rated. The rating comes in steps, from 20 min to 2 hrs. The first will be solid core wood doors and frames, the latter will be steel door and frames.

There used to be a practice of nailing a piece of sheet metal to the garage side of the door and that made it a fire door. I don't think that flies anymore.

Fire rated doors


Just Bill is right---A UL fire rating tag must be on the door or it will not pass inspection.

The frame is part of the fire rating---retrofitting an existing door will not pass.
