What makes a door fire-rated
A fire door is part of a tested assembly: a labelled door, a labelled frame, the specified hardware, seals and sometimes a glazing kit. The label shows the rating and the manufacturer's testing. Doors are used in corridors, stairwells, shafts and between tenants to keep fire and smoke from spreading.
They must be self-closing and latch every time. A rated door that is propped open or does not latch cannot do its job.
Installation details that count
Installation is highly regulated. Gaps around the door must stay within limits. Hardware has to be listed for fire use. Cutting a rated door on site for a lock, a vision panel or a new hole can void its rating unless done as allowed.
Because the frame is part of the wall assembly, our interior systems crew builds the rated wall and frame together, ensuring that anchors, grout and sealants meet requirements. Our door installers then hang the door and set closers, hinges and latches. Our electricians and low voltage team connect hold-open devices to the fire alarm, so doors release automatically when an alarm sounds.
We keep records of what was installed, so labels and hardware can be verified at inspection.
- Labelled doors, frames and hardware
- Self-closing hinges and closers
- Smoke seals and thresholds where required
- Magnetic hold-opens tied to fire alarm
- Rated glazing and vision panels
What to plan for
The design drives everything. Rated openings are identified on the drawings, and any change, such as a new door location or a different hardware set, needs review. Please tell your project manager about changes before ordering.
Inspections are routine. Authorities and consultants may check labels, gaps and operation. Allow time in the schedule for this and for corrections.
After handover, protect the rating. Doors should not be wedged open, modified or fitted with unapproved hardware. Regular inspection and maintenance of closers and latches are part of fire safety, and we can provide service.
