Features

Fire Resistance Ratings

Fire-rated doors are classified by their fire resistance ratings, which indicate the duration they can withstand fire exposure.Common ratings include 20-minute, 45-minute, 60-minute, 90-minute, and 3-hour ratings.

Self-Closing Mechanisms

Essential for maintaining the integrity of fire barriers, self-closing mechanisms ensure that fire-rated doors automatically close in the event of a fire. This feature is crucial in preventing the spread of fire and smoke, especially if occupants forget to close the door behind them.

Positive Latching

Positive latching mechanisms ensure that the door remains securely closed during a fire. This feature prevents the door from being pushed open by pressure changes or by people in a panic, thereby stopping smoke and heat from passing through gaps.

Smoke and Draft Control Features

To further enhance safety, fire-rated doors often include smoke and draft control features. These features prevent the spread of smoke and toxic gases, maintaining air quality and visibility during a fire.

Components of a Fire-rated Door

Door hardware

Door hardware includes protection plates, door-position switches, closing devices, hinges, and latching mechanisms. All these hardware parts must pass a certification process before they can be attached or incorporated into the assembly.

Vision lite

Some fire-rated doors have a vision lite glazed with fire-rated glass installed in them. This allows one to see what’s on the other side of the door during a fire and check whether it is safe for them to move to the other side as they try to find a safe exit path or alternate route.

Gasket and seal

Fire-rated doors are designed to be kept closed and completely sealed in case of a fire. This is where seals and gaskets come in. These materials fill the gap between the door and frame, preventing the spread of toxic gases and smoke during a fire.

Fire-rated Door Ratings

Fire door assemblies are rated based on how long they can withstand flames and control smoke during a fire. Here are some of the most common fire ratings.

Applications

Residential House-to-Garage Doors

Commonly required (e.g., 20-minute rating) in residential building codes to prevent garage fires from entering the living space.

Commercial Stairwells & Exit Paths

Used in high-rises and commercial buildings to keep stairwells and corridors smoke-free for safe occupant evacuation.

Mechanical & Electrical Rooms

Installed in utility rooms, boiler rooms, and elevator shafts to contain potential electrical or machinery fires.

Commercial Offices & Apartment Units

Used to create fire-resistant compartments between different tenants or apartment units to prevent fire from spreading throughout a building.
