Install Fire-Rated Garage Doors


Make Resilient Upgrades | Strengthen Your Home • Wildfires

Why do they matter?

The garage door is usually the largest opening in your home. Protecting that opening is crucial to preventing a wildfire from breaching the building envelope and spreading to the interior.

What do I need to know?

  • Garage doors are typically made of wood, aluminum, or steel, and are insulated or non-insulated.
  • Unlike standard doors, garage doors are not normally tested for fire resistance.
  • During a wildfire, you may need to leave your home immediately. If the power is out, some garage door openers may not operate. Be sure that your garage door opener has a backup battery function.

Where do I start?

  • Replace wooden garage doors, particularly if they do not have a solid core.
  • Specify and install insulated, metal garage doors.
  • The general rule is the thicker the metal door the better. Choose a three-layer garage door with steel outer layers and insulation in the middle for the best fire resistance.
  • To avoid embers and hot gasses penetrating the garage, install weatherstripping that has been tested to UL Standard 10C around the entire garage door.
