  1. minimum gap

    Nephelim posted a topic in Fire Doors and Accessories
    I'm inspecting firedoors where the gap at jamb is so tight you could barely fit a sheet of paper in. The data sheet and the fire test report only mention maximum allowable gaps. BS8214 (9.5.2) says that a typical gap should be 2 mm to 4mm. Is there a minimum allowable gap? Should I accept these doors? Thanks.
