Fire-rated doors are required in fire barriers or smoke partitions to compartmentalize fires and protect evacuation routes. Common locations include interior stairwells, corridors, elevator lobbies, mechanical/electrical rooms, and walls separating different tenant spaces or occupancies.
A fire-rated door is a specialized assembly designed to slow or stop the spread of fire and smoke. It is not just the door itself, but a complete system comprising the door leaf, frame, seals, glazing, and hardware that works together to compartmentalize a fire and keep exit routes clear.
In most new 2-storey houses, doors between internal rooms do not need to be fire resisting; however, any door between living spaces and an integral or attached garage should provide at least 30-minutes' fire resistance, be fitted with a self-closing device, and have effective cold smoke seals around its edges.
According to SCDF regulations, a fire-rated door is only mandatory if your main entrance is located within 3 meters of a staircase or lift lobby. Understanding these specific hdb fire rated door requirements helps ensure your home is both safe and compliant from day one.
The use and installation of kick-down door stops is permitted on non-fire rated doors only.
The most common material used for fire doors is timber, which can be either solid or engineered. Composite fire doors are an excellent option for those looking for a fire-resistant door that is also stylish and versatile.
A fire curtain can be specified as an alternative offering the same levels of integrity and, if required, additional smoke sealing. The fire curtain can be recessed within the ceiling and walls, or face fixed depending on customer requirements.
No. Not all steel doors are fire rated. A standard steel door — including most loft-style internal steel doors — provides no certified fire resistance unless it is specifically manufactured, tested, and certified for that purpose.
Fire Resistance Duration
Fundamentally, regulations state that any qualified fire door needs proven ability to hold back flames and heat for substantial periods of time. Common legal ratings making doors compliant include 30, 60 and 120 minute resistance, known as FD30, FD60 and FD120.
Unlike a standard door, a fire-rated door is constructed with fire-resistant materials that can endure intense heat and flames. It's all about the materials you don't see. The core of the door, filled with fire-resistant materials, is where its strength lies.
To tell if a door is a fire door, look for these key indicators:
Fire-rated doors slow the spread of fire and smoke for 20–90 minutes using dense cores and intumescent seals. Ideal for garages, stairways, and multi-story homes to enhance fire safety and meet building codes. They may reduce insurance premiums and increase evacuation time in emergencies.
Sliding doors work extremely well in environments where there may not be enough space for a regular fire door. This includes rooms such as kitchens, bedrooms and bathrooms. These doors use a pocket door system with the latest sliding door technology to allow for exceptionally easy installation.
Where to install fire doors. In public buildings and commercial premises, fire doors are required for all internal doors that lead to corridors and stairways. This is so that they can provide a clear escape path for occupants and prevent fire from restricting access to an emergency exit.
Types of Doors
A 20-minute fire-rated door is a specialized door engineered to withstand flames and block smoke for at least 20 minutes. It acts as a passive barrier, buying precious time for occupants to escape or for first responders to arrive in the event of a fire.
You generally need a fire-rated door to divide high-risk areas from safe zones, such as a door leading from an attached garage to the house, doors opening into stairwells, or doors separating apartments in multi-family buildings. Look for a metal label on the hinge edge, a self-closer, and check local building codes for mandated fire-rated assemblies.
Most modern, normal internal doors cannot be upgraded to achieve 30 or 60 minutes Fire Resistance due to them having a hollow core, being very thin or lightweight and liable to warping shortly after installation.
Exterior doors are not always required to be fire-rated. However, local building codes (like the International Building Code) strictly mandate them in specific high-risk scenarios, such as when a door sits close to a property line, is part of a commercial structure, or leads from an attached garage into a home.
Steel doors often offer up to 240 minutes of fire resistance, compared to the standard 30-60 minutes that most timber fire doors provide. This can significantly increase the chances of containing a fire before it spreads to other parts of a building.
Not by default. While solid and solid-core doors are more substantial than hollow ones, they only qualify as true fire-rated doors if they are officially tested, certified, and carry a manufacturer's label proving they meet specific fire-resistance standards.
We found this product to be a quality, fire-rated door at an affordable price. Our purchase of the Jeld-Wen fire-rated 6-panel door was a good one.
The closet had two sliding doors that made the space difficult to use from a functional standpoint. By taking them off, not only would it be easier to simply use the closet, but I could also fit my second dresser inside. Like this, it wouldn't take up unnecessary floorspace, and the closet was instantly easier to use.
If the door has glazing, the glass panel(s) must be replaced with a fire rated glass. The upgraded door must be re-hung with at least three fire protected hinges, to prevent warping. The integrity of a fire door will be severely compromised if it should warp, as it will no longer fit snugly in its frame creating gaps.
Yes. You need fire doors in all non-domestic properties: businesses, commercial premises and public buildings. They're also mandatory in residential flats and houses of multiple occupancy.
