A 90-minute fire rated door should be reviewed as a listed opening system. Door size, leaf construction, frame, hardware and any glazed opening need to remain within the approved configuration.
Match the rating to the documented opening
A 90-minute requirement should be traced to the project life-safety documents and wall condition. It is not a universal upgrade that can be applied without checking the surrounding assembly.
Control the details that change the assembly
Glazing, louvers, door pairs, exit devices and electrified hardware can affect the permitted construction. Provide these details before the door and frame preparations are finalized.
- Opening dimensions and pair configuration
- Frame profile and anchor condition
- Hardware function and latching
- Glazing or louver details
- Required labels and documentation
Review installation before handover
Field drilling, unapproved modifications and clearance problems can undermine a correctly manufactured opening. Use the approved shop drawings and assembly instructions during installation and inspection.
