Browse 7 fire-rated interior doors — tested and certified to ULC standards for 20-minute, 45-minute, and 90-minute fire resistance ratings. Required by Canadian building code for garage-to-house openings, condo unit entries, stairwell separations in multi-unit buildings, and certain commercial applications.
Where fire-rated doors are required
20-minute: Garage-to-house openings in residential homes. 45-minute: Condo unit entry doors and some corridor separations. 90-minute: Stairwell fire separations in multi-storey commercial and residential buildings. Always confirm with your local building inspector which rating your project requires.
Important: don't separate door from frame
Fire-rated doors are sold as pre-hung assemblies with matching fire-rated frames. Separating the door from its rated frame voids the fire rating. Never install a fire-rated slab in a non-rated frame.

A fire-rated door is tested and certified to resist fire for a specific time — typically 20, 45, or 90 minutes. The door slows the spread of fire and smoke between rooms, giving occupants time to evacuate. Fire-rated doors are required by building codes in specific locations like garage-to-house entries, furnace rooms, and multi-unit dwellings.
Do I need a fire-rated door?
Building codes in Ontario and across Canada require fire-rated doors in specific locations: between attached garages and living spaces, furnace and utility rooms, stairwell entries in multi-storey buildings, and shared walls in townhomes and condos. Check your local building code or ask your contractor if you're unsure.
What fire rating do I need — 20, 45, or 90 minutes?
20-minute rated doors are standard for most residential applications — garage entries, utility rooms. 45-minute doors are required in some multi-unit buildings and commercial corridors. 90-minute doors are used in high-risk commercial and industrial settings. Your building code or fire inspector will specify the required rating.
Can fire-rated doors be trimmed or modified?
No. Cutting, drilling, or modifying a fire-rated door voids its certification. Order the correct size — fire-rated doors must fit the opening as manufactured. If your rough opening doesn't match standard sizes, you'll need to adjust the opening, not the door.
