Doors between the dwelling and the garage also provide some resistance to fire but do not require an assembly with a fire-resistance rating. In other words, the frame, hardware, and sealing of the opening are not addressed, only the materials of the door leaf itself. Any one of the following types of door satisfies the separation requirement:

For the door between the house and the garage, all that is necessary is to install a door that meets the “fire separation requirements” of the code. Of course this door can never lead to a bedroom. There is nothing that says it has to be a “fire-rated door,” as frequently reported by home inspectors.

Only common walls between garage and house (not perpendicular walls) must meet this requirement. If a garage is detached, but within 3-feet of the residence, any walls within 3-feet must have 1/2” drywall. When there is a living area (habitable space) above the garage, the ceiling requirement ramps up to 5/8” Type X fire-rated drywall.

Fire-rated doors are interior doors leading into the attached garage that have added safety features to protect you, your family, and your belongings from fire, smoke, and carbon monoxide. “Fire-rated” is the term used to describe the length of time the door can withstand the heat and flames from an average-sized fire, for example, fire ...

The wall between the house and the garage–believe it or not–is NOT a fire-rated assembly and is referred to in the code as the “Dwelling-Garage Separation.” Meeting the “separation” requirements is really quite simple and minimal compared to what would be necessary in an actual “fire-rated assembly” (As would be required between ...

One myth is that a fire-rated door will protect your home from a fire in the garage. This is not true. Fire-rated doors only provide a barrier to prevent the spread of fire and smoke. Another myth is that a firewall between the garage and house will protect your home from a fire in the garage. This is also not true.

A fire-rated door for the garage is specifically designed to withstand fire and high heat for a specified period, such as 20, 45, or even 90 minutes, depending on its fire resistance rating. Unlike standard doors, fire-rated doors are constructed using durable, non-combustible materials like steel, fiberglass, or specially treated wood composites.

Fire-rated doors have time ratings. These designations vary. However, the standard fire-rated doors rate between 20- and 90-minute doors. Fire-rated doors are more commonly installed in commercial buildings. However, they are also one of the required options you can choose from when selecting your garage entry door.

A fire rating only applies to an assembly – a particular grouping of construction materials assembled in a particular way. This code requirement for garage separation isn’t a fire rating requirement. It’s simply a requirement for how you have to treat the walls and ceilings between the garage and the house.

An opening has been cut into the bottom of an otherwise acceptable door to install a pet door. A steel door with a fixed glass panel that is not fire-rated has been installed. We check the “bug” on the glass and it is usually safety glass, but have yet to find one with glass that is fire-rated. The door shown below is an example.

Acceptable Types of Doors. There are several types of doors that meet the fire safety requirements outlined in the IRC. These include: Solid Wood Door: A solid wood door used for this purpose must be not less than 1-3/8 inches thick. Solid or Honeycomb-Core Steel Door: Similar to a solid wood door, a solid or honeycomb-core steel door must also be not less than 1-3/8 inches thick to meet the ...

Garage fire wall / separation wall between the house and an attached garage is very often mistreated by the home owners. I’m assuming that they are simply unaware of the fire safety requirements and how critical it might be to gain those extra minutes that garage fire wall should provide in case of fire. As always. check your local jurisdiction requirements, because they might exceed the IRC ...

Fire barrier opening exceptions do not apply to glass wall separations because smoke partitions have different design requirements than fire. A common misconception: sprinkler-protected glass according to the atrium exception is not a fire-resistance-rated assembly and cannot replace fire barriers in other parts of a building.

Other openings between the garage and residence shall be equipped with solid wood doors not less than 1 3/8 inches (35 mm) in thickness, solid or honeycomb-core steel doors not less than 1 3/8 inches (35 mm) thick, or 20-minute fire-rated doors, equipped with a self-closing or automatic-closing device.
