Limits to plan for

- Larger lites need fire-resistive glass marked D-H-T or D-H-W
- Maximum leaf sizes and pair sizes depend on the listing
How we supply rated doors
- Every fire-rated door we supply is built and labeled by a manufacturer that holds the listing for that door with a nationally recognized testing laboratory, such as UL or Intertek (Warnock Hersey), and is inspected under the lab's follow-up service.
- The label is applied at the factory. We never apply, move or replace fire labels, and we do not field-label.
- We take your door schedule and hardware schedule, check each opening against the listing, and have doors factory-machined for your hinges, locks, closers and electrified hardware.
- Matching non-rated doors in the same veneer, paint or laminate come from the same order, so a corridor looks the same whether a door is rated or not.
- Documentation for submittals and closeout: listing references, label type per opening, hardware compatibility and installation instructions.
Questions
Frequently asked.
Why mineral core?
Mineral cores are non-combustible and are what wood doors use to reach 45 to 90 minutes. Hinge and lock blocking is built in for screw holding.
What is a temperature-rise door?
Doors into exit stairways and passageways may need to limit the temperature on the unexposed side to 450 °F above ambient after 30 minutes, so people can pass. The label states it.
Can the doors be stained or veneer-matched?
Yes. Faces can be veneer, paint-grade or laminate, and can be matched to non-rated doors and millwork in the same space.
