What Are Fire-Rated Doors?

Fire-rated doors are specially engineered door systems designed to resist fire for a specific period of time—typically 20, 45, 60, or 90 minutes. These doors play a critical role in slowing the spread of fire and smoke, protecting occupants, and giving people more time to safely evacuate a building.

Unlike standard doors, fire-rated doors are constructed with reinforced cores (steel, solid wood, or composite materials), fire-resistant glass (if vision panels are included), and intumescent seals that expand when exposed to heat. This creates a tight barrier that helps block flames, smoke, and toxic gases.

Key Benefits of Fire-Rated Doors:
✔ Slows the spread of fire and smoke
✔ Protects evacuation routes and stairwells
✔ Helps meet building and fire code regulations
✔ Increases safety for occupants and property
✔ Available in various designs, finishes, and configuration

​Common Applications:

Fire-rated doors are commonly installed in a wide range of commercial and industrial environments, including commercial storefronts, office buildings, stairwells and exit corridors, schools and hospitals, warehouses and industrial facilities, as well as mechanical and electrical rooms and interior fire-rated partitions where fire separation is required.
