Choosing the Right Fire-Rated Garage Door

1. What Are Fire-Rated Doors?
Fire-rated doors are specially designed doors that resist fire and smoke for a specified period, typically 20, 45, 60, or 90 minutes. These doors are tested and certified to withstand extreme heat, preventing flames from spreading to other areas of a building.
Key Features of Fire-Rated Doors:
-
Fire-Resistant Core: Made of materials like steel, gypsum, or vermiculite.
-
Intumescent Seals: Expand when exposed to heat, sealing gaps to block smoke.
-
Self-Closing Mechanism: Ensures the door automatically shuts in case of fire.
-
Certified Hardware: Hinges, locks, and frames must also be fire-rated.
Fire-rated doors are mandatory in commercial buildings, multi-family homes, and garages attached to living spaces.
2. Why Fire-Rated Garage Doors Are Essential
Garages often store flammable materials like gasoline, paint, and tools, making them high-risk areas for fires. A fire-rated interior garage door provides a critical barrier between the garage and the main living space, preventing fire from spreading quickly.
Benefits of Fire-Rated Garage Doors:
✔ Slows Fire Spread: Gives occupants more time to evacuate.
✔ Blocks Toxic Smoke: Prevents smoke inhalation, the leading cause of fire-related deaths.
✔ Meets Building Codes: Required by the International Building Code (IBC) and National Fire Protection Association (NFPA).
✔ Insurance Compliance: May lower insurance premiums due to enhanced safety.
Without a fire-rated garage door, a small garage fire could engulf an entire home in minutes.
