Premium 90-Minute Fire Rated Commercial Wood Doors
When life safety and strict building codes are on the line, you cannot afford to compromise on quality. But meeting fire codes shouldn't mean sacrificing your building's interior design.
Designed for high-traffic environments like hospitals, schools, hotels, and corporate offices, our fire rated commercial wood doors (90 minute) provide the ultimate balance of rigorous safety compliance and premium aesthetics. Whether you are an architect drafting a new commercial space or a contractor needing to pass a final fire marshal inspection, these doors are engineered to perform under pressure.
Why Choose Our Architectural Grade Commercial Wood Doors?
- Uncompromising Safety (90-Minute Rating): Built with a specialized non-combustible mineral core, these doors are tested and certified to withstand fire exposure for up to 90 minutes, giving occupants critical time to evacuate and localizing property damage.
- Seamless Frame Compatibility: Need to mount these in existing openings? Our doors are perfectly matched to work as commercial wood doors with metal frames. They fit standard hollow metal knock-down (KD) or welded frames without a hitch.
- Vision Lite Integration: You don't have to choose between a fire rating and natural light. We supply commercial solid core wood doors with glass, utilizing certified fire-lite ceramic glazing and approved metal vision frames that maintain the integrity of the 90-minute rating.
- Factory-Machined Precision: Stop wasting time routering on the job site. We deliver these doors perfectly prepped for your exact commercial hardware-including cylindrical locks, mortise locks, panic bars, and commercial hinges.

FAQ
Q: Can I get a 90-minute fire-rated commercial wood door with glass?
A: Yes. We can install vision lites in our 90-minute doors, provided we use specialized fire-rated ceramic glass and approved metal vision frames. Keep in mind that building and fire codes heavily restrict the maximum square footage of glass allowed in a 90-minute door.
Q: What type of frame do I need for a 90-minute wood door?
A: To maintain the 90-minute fire rating of the opening, the door must be hung in a fire-rated frame. Typically, this means installing the door in a hollow metal commercial frame that carries an equal or greater fire label (usually 90-minute or 3-hour).
Q: What is a "mineral core" and why is it necessary?
A: Unlike standard particleboard or solid lumber, a mineral core is a specialized, non-combustible material made from minerals and binders. It is absolutely mandatory for achieving a 45-, 60-, or 90-minute fire label on a wood door, as standard wood cores will burn through too quickly.
Q: Do these doors meet NFPA 80 standards?
A: Absolutely. All of our fire-rated doors are manufactured, tested, and labeled in strict accordance with NFPA 80 (Standard for Fire Doors and Other Opening Protectives), ensuring you pass your local building and fire marshal inspections.
Q: Are these doors heavy-duty enough for high-traffic areas?
A: Yes. While the core is mineral-based to stop fire, the exterior utilizes high-density hardwood stiles and rails, wrapped in architectural-grade wood veneer. They are built specifically to withstand the daily abuse of schools, hospitals, and busy commercial corridors.
Q: Do you prep the doors for panic bars and door closers?
A: Yes, we provide full factory machining. Because drilling into a mineral core on the job site can be difficult and risks voiding the fire label, we highly recommend letting us prep the door for your exact hinges, locksets, panic hardware, and closers at our factory based on your hardware schedule.
Q: How long is the lead time for custom architectural grade wood doors?
A: Because each door is machined to specific hardware templates and finished to your exact veneer requirements, standard lead times range from 4 to 6 weeks. However, we do offer expedited programs for urgent replacement projects. Please contact our estimating team with your deadlines.
