Fire rated doors are made with unique materials that prevent smoke and fire from spreading for a predetermined amount of time, usually between 20 minutes and up to three hours. These doors include seals around the edges that prevent fires. The goal of fire rated doors in Toronto, which are approved and tested to fulfill safety requirements, is to shield the remainder of the structure from additional damage while offering a secure escape route in the event of a fire.
How Do Fire Rated Doors Work?
Fire-rated doors are made to slow or stop smoke and fire from spreading between a building’s compartments. Because they lessen property damage and provide inhabitants more time to flee, they are essential to fire safety.
The fire resistance of fire doors is measured and rated, typically 20, 45, 60, 90, or 120 minutes. The rating shows how long the door can withstand heat, smoke, and flames before deteriorating or losing its structural integrity.
Self-closing mechanisms are typically installed on these doors to guarantee that, in the case of a fire, they will shut on their own. Certain models feature electromagnetic hold-open mechanisms that activate in response to a fire alarm, guaranteeing that the door closes securely.
The edges of fire-rated doors frequently have intumescent seals, which swell up in intense heat. By bridging the spaces between the door and the frame, this extension stops smoke and fire from spreading.
Types of Fire Rated Doors
- Fire rated doors made of steel. Made of steel with an internal mineral core or honeycomb structure. Fire Rating: 45 minutes to three hours is possible. Because of their longevity, they are widely employed in commercial, industrial, and high-traffic locations.
- Glass fire doors are usually composed of fire-resistant glass, such as ceramic, laminated, or wired glass. Fire Rating: depending on the type of glass, it might range from 20 to 90 minutes. Frequently utilized in retail establishments and office buildings where fire safety is still maintained but visibility is crucial.
- Fiberglass reinforced materials with fire-resistant cores are the materials used for fiberglass fire doors. Fire Rating: 20 to 90 minutes is possible. Appropriate for places like hospitals or industrial locations with severe weather or a lot of dampness.
- Aluminum fire doors are composed of aluminum that has been treated to resist fire. Fire rating is usually between sixty and ninety minutes. Often found in contemporary office buildings and educational institutions, as well as commercial venues.
- Rolling steel fire doors. Made of steel slats that automatically collapse in the case of a fire. Fire rating: three hours or more. Mostly used as an opening protector in parking garages, warehouses, and other commercial buildings.
- Fire doors made of hollow metal. Composed of an insulating core surrounded by a shell of steel or another metal. Fire rating: generally one to three hours. Frequently found in business building stairwells and industrial environments.
Key Features of Residential Fire Rated Doors
Residential fire-rated doors are made to restrict the spread of smoke and fire inside a house, improving safety.
The key features are as follows:
- Fire resistance rating,
- Material composition,
- Intumescent seals,
- Self-closing mechanism,
- Smoke seals,
- Reinforced frames,
- Certification and labelling,
- Thickness,
- Aesthetic options.
Fire Rating Classifications and Standards
Flame spread class ratings A, B, and C:
Class A: maximum level of fire resistance; flame spread index, 0–25.
Class B: moderate fire resistance, with a flame spread index of 26–75.
Class C: the lowest fire resistance permitted by the law, with a flame spread index of 76–200.
Hourly Ratings:
Ratings for twenty, forty, sixty, ninety, and one hundred minutes: these show the amount of time that a fire-rated component, such as a wall or door, can sustain fire exposure before failing.
Fire Rating Standards:
- Fire Rating Standards NFPA (National Fire Protection Association) 80: defines the conditions under which fire-rated components must be installed, maintained, and tested. It covers fire doors, frames, and other protective apertures.
- The ASTM E119 standard test methods are used for fire tests of building materials and construction. This test evaluates the structural integrity and temperature tolerance of walls, floors, and ceilings in relation to fire exposure.
- UL 10B and 10C (Underwriters Laboratories):
UL 10B: heat and flame testing is used to determine how fire resistant a door is. UL 10C: for positive pressure fire tests on door assemblies, this standard is comparable to UL 10B.
- An international standard called ISO 834 describes how to test building elements for fire resistance and helps determine how long assemblies or materials can sustain high temperatures.
- Building materials and components that are specifically used in Canadian codes are tested for fire resistance by CAN/ULC-S101 (Canada).
Materials Used in Fire Rated Doors
- Steel. Because of its strength and fire resistance, steel is one of the materials used in fire-rated doors the most frequently.
- Aluminum. Aluminum can be used for fire-rated doors, especially for frames, even though it is less prevalent than steel. To enhance its performance, aluminum is frequently paired with glass or fire-resistant cores.
- Wood. Doors made of solid core wood can be rated for fire protection, frequently with additional fire-resistant treatments. In order to meet fire regulations, these doors are usually thicker and may include an interior core composed of non-combustible materials, such as gypsum.
- Intumescent seals. These seals are necessary but not a material for doors. Intumescent seals expand in response to heat, sealing gaps and halting the spread of smoke and fire surrounding the door.
Benefits of Installing Fire Rated Doors
- Enhanced safety. Fire-rated doors are made to withstand the spread of fire for a predetermined amount of time, such as 20, 60, or 90 minutes. This extra time allows first responders to contain the fire and allows inhabitants to flee.
- Smoke and gas barrier. These doors stop the flow of harmful gas and smoke, which are frequently more destructive than flames in a fire. They also stop fires.
- Complies with building rules. The installation of fire-rated doors contributes to compliance of local and federal building rules, which frequently call for these doors in places like stairwells, hallways, and the gaps between garages and living rooms.
- Sturdy construction. Fire-rated doors are typically constructed from sturdy materials like steel, aluminum, or reinforced wood, which gives them an extra degree of security against intruders and makes them extremely durable.
- Sound insulation. Because of their thick structure, many fire-rated doors are also excellent at suppressing noise, which makes them perfect for locations where you wish to limit sound, such as hallways and offices.
- Insulation. Fire-rated doors frequently feature good insulation, which helps raise a building’s thermal efficiency and lower heating and cooling expenses.
- Extra safety feature. Installing fire-rated doors can raise a property’s market value since it demonstrates a commitment to security, safety, and adherence to contemporary building codes.
- Customizable solutions. Fire-rated doors are available in a range of designs and coatings, so you may choose solutions that complement the appearance of your house without sacrificing security. Some even have glazing choices that provide fire protection and let in natural light.
Fire Rated Doors vs. Regular Doors: What’s the Difference?
| Fire rated doors | Regular door |
| Depending on their grade, these doors are specifically made to withstand fire for a set amount of time, typically between 20 minutes and 3 hours. They are inspected to make sure they adhere to strict fire safety regulations and are constructed from materials like steel, gypsum, or wood with a fire-resistant core. | Fire protection is not provided by standard doors. Usually composed of materials like steel, fiberglass, hollow-core wood, or wood, they may not be able to resist fire or stop it from spreading for extended periods of time. |
| These doors include expandable seals that stop smoke and flames from spreading when they come into contact with extreme heat. In some parts of residential and commercial buildings, such as the stairwells of apartment buildings or the spaces between garages and interiors, they are necessary. | They are not made to block smoke or fire, nor do they have these specific safety characteristics. |
| Fire-rated doors cost more than ordinary doors since they are made of specific materials and undergo testing. Depending on the material and fire rating, the price may change. | These come without the extra fire safety regulations, are typically more reasonably priced, and come in a larger variety of styles and materials. |
| To preserve their fire-resistant qualities, they must be placed in accordance with tight instructions. Hardware such as frames, hinges, and others have to be fire-rated. | There are no special fire safety standards, thus installation is easier. |
| Although they can be made to match the architectural design of a structure, the safety regulations frequently give them a more utilitarian appearance. Modern designs, however, are combining aesthetics with fire safety. | More stylistic and appearance options are available to homeowners and designers thanks to their increased variety in designs, materials, and finishes. |
| Used in commercial buildings, residential complexes, garages, and specific areas of residential dwellings where fire safety is an issue. | Widely utilized in places where fire resistance is not required, such as workplaces and houses. |
Installation Requirements for Fire Rated Doors
To guarantee that the fire-rated door performs as intended in an emergency, proper installation is essential:
- To ensure optimal performance, keep the designated clearances surrounding the door. Generally speaking, the top and vertical borders should have gaps of no more than 1/8″ (3.18 mm).
- The maximum bottom opening for non-smoke-rated doors is 3/4″ (19.05 mm). Doors rated for smoke demand a tighter seal.
- The fire rating of the wall where the door is mounted must coincide with the rating of the door itself. For the installation to stop the fire from spreading through gaps, it must be smooth and flawless.
- Make sure the installation abides by the building and fire codes in the area.
Common Myths About Fire Rated Doors
- Many people think that fire-rated doors are fireproof, capable of withstanding any kind of fire. In general, fire-rated doors are not totally fireproof; rather, they are made to withstand fire for a predetermined amount of time (such as 20, 30, 60, or 90 minutes).
- A door can be fire-rated for any reason: not every door can be made fire-rated. Fire-rated doors are made of materials that can withstand fire for a predetermined amount of time after undergoing special testing.
- Installing fire-rated doors does not require expert installation: to guarantee that the door operates properly in the event of a fire, proper installation is essential. Installing a door yourself may reduce its efficiency.
- Fire-rated doors require no maintenance once installed: it is imperative to perform routine maintenance. In a fire, doors, frames, or seals that are damaged may be less effective.
- Fire-rated doors are only for business buildings: although they are frequently needed in business settings, fire-rated doors are also necessary for safety in many residential buildings, particularly multi-family housing and garages.
- They are difficult to use and are too heavy: even while fire-rated doors can weigh more than regular doors, many of them are made to be accessible standards compliant and user-friendly.
- Fire-rated doors don’t look good: numerous visually appealing fire-rated doors are available to match a range of interior design styles.
- Fire-rated doors are modifiable: rire-rated doors can lose their fire rating and safety compliance if they are modified, such as by drilling holes for hardware.
