Fire Door Frames
Problems with the fire-door frame, alignment, fixing, movement, distortion or the relationship between the frame and door leaf. Key principle: the door leaf is a solid, rigid rectangle. The frame is the component that can move, twist, rack or taper around it. This section brings together practical guidance for identifying and understanding frame-related faults.
Fire Door Frame Movement: Diagnose Fixings, Load and Wall Conditions
Frame movement can change gaps, affect latch alignment and cause recurring faults. Possible contributors include missing fixings, inadequate packing, hinge loading, wall movement, moisture changes or earlier remedial work. Record the gap pattern, check for cracking and observe whether movement occurs during operation. Establish the fixing and wall-junction details before repair; forcing one point can transfer the problem elsewhere. See fault finding, installation guidance and Find a Subject.
