Double vs Single Fire Doors: Which Type Should You Install?

Fire doors come in single leaf and double leaf configurations. Which type is best to install in your building project?

There are many different types of fire doors. Today, we will be reviewing the functionality and purpose of single leaf and double leaf doors, which are common configurations. When manufactured, installed and maintained properly, both fire door types can provide effective protection in the event of a fire emergency. However, you may be wondering, which door configuration would be most appropriate for your particular property or building project?

Here at Fire Safe Doors, we specialise in all things fire door-related, from the manufacturing, installation and testing, to the assessment and upgrading of both fire-rated and non-fire-rated doors. Today, we will be providing you with some key information on single leaf and double leaf fire doors, so that you can make an informed decision on which type of door would meet your fire safety and logistical requirements best.

1. Single Leaf Fire Doors

Put simply, a door leaf is a single, free-moving panel of a door. A single leaf fire door comprises one panel that is situated inside the door frame when closed. Single leaf fire doors are ideal for smaller spaces that incur less foot traffic.

This type of door configuration is commonly seen in areas such as stairwells of apartments and hotels, office buildings, stores, and some residential properties. As outlined by the Building Code of Australia (BCA), single leaf fire doors must be in compliance with what is specified in the code AS 1905.1.

2. Double Leaf Fire Doors

A double leaf fire door consists of two panels, both of which open outward, at their centre meeting point, in a swinging motion. They are ideal for larger spaces and buildings with high foot traffic, due to their two-way swing.

This type of fire door configuration is commonly seen in hospitals, shopping centres, schools, warehouses and other large spaces. As outlined by the Building Code of Australia (BCA), double leaf fire doors must be in compliance with what is specified in the codes AS1530 and AS1905

Fire Door Inspection Guide for Commercial Properties

Fire door inspections are a crucial safety measure and legal requirement for commercial, industrial and residential properties. How often should they be conducted and what do they entail?

Over time, certain components of fire doors may deteriorate, get damaged or become outdated, thus requiring maintenance, repair or replacement. If the necessary improvements are not made to these doors, it can compromise their effectiveness in the event of fire emergencies, and cause a decline in their FRL (fire-resistance level). Additionally, their existing condition may no longer comply with fire safety regulations.

So, with that in mind, you may be wondering, how often should the fire doors in your buildings be inspected, and what are the steps involved? Here at Fire Safe Doors, we specialise in all things fire door-related, from the manufacturing, installation and testing, to the assessment and upgrading of both fire-rated and non-fire-rated doors. Today, we’ll be providing you with essential information on commercial fire door inspections, so that you can be prepared for the process, and ensure your fire doors are up to standard.

1. How often should Fire Door Inspections be conducted?

The frequency of compulsory fire door inspections depends on the building’s classification, as outlined by the Building Code of Australia (BCA). As specified in the code AS1851-2012, both fire doors and smoke doors in commercial buildings require an inspection every 6 months, whereas in residential and industrial buildings, they require one inspection per year. However, sliding fire doors in particular require a minimum of one inspection every 3 months.

Additionally, passive fire door systems, like smoke alarms and sprinklers for example, need to be inspected at least once annually. However, more frequent checks are advised.

2. What does the inspection process involve?

During fire door inspections, a number of compliance criteria are assessed in order to determine whether the doors are in proper working order or if they require adjustments. The components that are checked include the following:

  • Compliance Tags: Once installed, fire doors must have compliance tags affixed to them. During the inspection process, we check to see if these tags are present and legible. Here at Fire Safe Doors, as part of our BCA/AS requirements, expert tagging and certification are provided by CFDS on the completion of our works to our client’s satisfaction.
  • Doors, Frames and Hardware: If any holes or breaks are identified on the doors, door frames or hardware, they must be repaired or replaced with the appropriate materials as soon as possible.
  • Glass and Glazing: For glass fire doors in particular, the glass as well as its fire-resistant glazing should be analysed for any sings of cracks or other damage. The glazing beads should also be inspected, to ensure that they are properly intact, fastened, and free from damage.
  • Gaps: There must be no gaps exceeding 3mm between doors and their frames, and this can result in smoke and flames being able to make their way through to other areas of buildings during fire emergencies. Identifying any gaps that will require sealing is a crucial part of the fire door inspection process.
  • Safety Obstructions: One of the most important elements of a fire safety plan is ensuring you have a clear evacuation pathway in the event of a fire emergency. Therefore, fire doors should never be locked, nor should they be obstructed by heavy or hazardous objects. An effective fire door inspection will identify any prevalent obstructions and devise strategies to mitigate them.
  • Broken or Missing Elements: Proper and holistic fire door inspections will identify any parts that are damaged or missing from doors, and arrange for them to be replaced, repaired or added as soon as possible.

Compliance Tags and Construction: Critical Fire Door Choices

While choosing the right fire doors for your construction is critical, you should keep in mind that installing fire doors correctly is just as important.

Why Is the Right Fire Door Installation So Important?

The process of installing fire doors must be in compliance with the current national standards and requirements set out by the Building Code of Australia and the relevant Australian Standards (AS 1905.1 and AS1530.4).

Failure to adhere to these codes can result in penalties, as well as additional costs in having to upgrade or fix your doors or installation faults.

In addition to this, correctly installing fire doors is a significant component of your building’s fire safety plan and is essential in saving lives and preventing extensive damage in the event of a fire.

Before Installing Your Fire Doors, You Should:

•    Ensure that the individual or company you have hired to install the doors is fully licensed and qualified to carry out the fire safety installation and certification

•    Make sure that your fire doors are being installed in fire walls and that the type of door chosen will preserve the fire rating of that same wall

•    Double-check that all doors, door frames and hardware is on par with the tested/approved prototype for that door and its accessories

•    Confirm with your builder or installer that all your fire doors will be installed in accordance with the tested/approved construction and installation requirements for that door.

Installing Your Fire Doors

It is crucial that your fire door installation receives the required fire rating once installation is complete. If your installation does not meet the standards for certification, you will need to replace or re-install the door. Also be vary of the different types of fire doors – sliding fire doors, hinged fire doors and double action fire doors – and how installation may vary between them.

When installing fire doors, you must ensure that:

•    Your door leaf is being installed and hung the correct way up, particularly if the door has been pre-fitted with plates for hinges and locks
•    No more than 6mm is to be trimmed from any edge of the fire door; if you need to trim more than 6mm off the door, you will need to order a custom door to fit your specific sizing needs
•    Only 3mm of clearance must be evident between the custom fire door and the frame at the head and the stiles; if more than a 3mm gap exists, your fire door will be non-compliant
•    No more than 10mm and no less than 3mm of clearance must be evident between the fire door and finished floor; if more than a 10mm gap exists between the door and floor, your door will not comply with Australian standards
•    The sill of the opening must be made from a non-combustible product, such as concrete
•    The locks or closing mechanisms on each door have been fire tested and certified (remember, all fire doors must be self-latching); all furniture, handles and any other fixture fitted to the door leaf must be tested/ and certified locks must have a 127mm back set
•    No deadbolts (or similar locks) are installed on any fire door; this goes against the Building Codes of Australia, is contrary to the Australian Standards and will result in non-compliancey

Compliance Tags

Once your fire-rated doors and frames have been correctly installed, the final part of the installation process is to fix each of your doors with a Compliance Tag (see also – fire door signage).

•    A Compliance Tag confirms that the door it is attached to has been tested, installed correctly and that it is able to uphold the relevant fire-resistant rating
•    All Compliance Tags should include the necessary fire door information, such as: the manufacturer’s name, fire rating/resistant level, owner’s name, certifier’s name, the year the door was manufactured and the item serial number
•    A Compliance Tag must remain on the door for the life of the door; beware of using low quality adhesive that will cause the tag to become ‘unstuck’ over time – this can result in both non-compliance and can cause inspection/maintenance problems later on.

1. Types of fire door installation

Our Fire Safe Doors team has years of experience in the supply and installation of many fire door types, comprising different materials. This includes the installation of internal and external door panels, sliding fire doors and glass fire doors. However, no matter the project, we recommend installing a fire-rated door over a non-fire-rated door. A fire-rated door set comprises a fire door frame, fire door leaf, and hardware including handles, locks, air grilles and vision panels.

As specified under Australian Standard AS1905.1, Fire rated door sets must be self-latching to gain certification. Once a fire door set has ben installed properly, a tag and certificate is granted and placed on the fire door frame. Here at Fire Safe Doors, we conduct out work in both fire-rated and non-fire-rated facilities. We also provide certification for fire-rated door supply and installations. Furthermore, we ensure that all our work complies with any building or fire safety codes.

2. Key installation tips

According to the BCA (Building Code of Australia), all fire doors must be installed in compliance with the Australian Standard AS/NZS 1905.1.2015. This set of guidelines describes the key requirements necessary to ensure that all doors are fitted into a property correctly.  Here are some of the key points outlined by the regulation.

  • Fire-rated door frames need to be fitted to tested prototype specifications.
  • Generally, the clearance between the fire door and frame at the head of the stiles must not go over 3mm.
  • The sill of the opening must comprise either concrete or another non-combustible material.
  • Close attention must be paid to how the door is hung, to ensure it is facing the correct way.
  • Once the installation process is over, fire door sets must have metal certification tags (AS 1905.1 2015) added to them.

Installation of Fire Doors

Fitting fire doors correctly is critical to their performance and long-term serviceability. Here is a quick rundown of the installation process.

• Before commencing installation, check that all hardware and fixings are on hand to be able to complete the job. It is also recommended that the latest revision of the door schedule is being used and the door is correct for the opening.

• Once the pre-checks are complete, measure the reveal height, and width, to check if the doors will fit into the opening. If you are replacing existing fire doors, do not use them for reference, as they may not have been fitted correctly in the first place.  Always scribe the door to the frame and never rely on guesswork. Removing too much material from any one part of the perimeter of the door can dramatically weaken it and make it redundant.

• Check hinges are well secured, that they move freely with no biding and that there is sufficient quantity the size of the door. The Door Manufacturer’s markings will identify the hinge and lock side. Mark the fire doors on the top face hinge side for ongoing reference.

• Open the hinges then place door leaf in the frame. It should be noted that all frames for fire doors should also be fire rated. Wedge the door into the head of the frame and scribe the door with a 2.5mm spacer. Check that the bottom clearance does to exceed the maximum recommended gap of 10mm before proceeding any further.

fire-rated doors

• Starting with the hinge side, machine door to scribe marks and finish by planing a 2mm splay or “Back edge”.  Back edge will ensure the closing door edge does not bind on the door frame. Using a sharp chisel or trimmer, cut the check out for the door hinges and fit them to the door using the correct, approved fixings.

• Next, plane the lock side to the scribe marks remembering to leave a 2mm splay or “Back edge”. Sand edges and paint the top and bottom of the door with an oil-based paint.

• Place the door onto the door frame, attach the hinges and check the door swings freely and without binding. Even the gaps on all edges by easing the hinges, ensuring that the gap between the frame and door does not exceed 3mm. Fit the nominated door hardware and adjust to ensure backcheck is in operation and the door latches all as required under AS1905.1.

• Once the installation is complete and the installer is satisfied that the doorset is fully operational and complies with the requirements of AS1905.1, affix the metal identification and approval tag, record the number ready for the issuance of the Door Certificate.

Fire Rated Glazing, Explained

Fire Rated Glazing is an ideal option for environments that need visibility as well as fire protection.

When we think of a fire door, we probably don’t think of a wide glass door. That’s because the majority of fire doors are built with steel and timber, not to mention the vermiculate core board, responsible for keeping the whole design insulant.

However, sometimes, for aesthetic or functional reasons, a solid material just won’t cut it. That’s where fire-rated glazing comes in. Let’s talk about how it works, its uses, and when to opt for the protective glaze.

How it works

The most important function to examine when discussing fire-rated glazing is its two different specifications; fire-protective, and fire-resistive.

Fire-protective glazing will prevent smoke and fire from spreading, however, it will not combat heat transfer. This means that the glass on the other side will still be dangerous to touch, and objects on the other side of the fire will still heat up – people included. If you’ve ever stood close to a campfire you’ll know just how fierce that heat can be.

On the other hand, fire-resistive glazing will prevent smoke and fire from spreading as well as conducting heat. This means the high temperature will be less easily transferred to the opposing room. This radiant heat is contained via a ‘fire-resistive assembly’, which means the multiple layers of glass are separated with interlayers, designed to resist heat.

Which type of glazing does my building need?

Obviously, fire-resistive glazing is the most optimum glaze to achieve the ultimate, longest-lasting fire protection. That being said, your building may already have enough fire-safety exits or measurements in place for it to pass the legal requirements without the premium glaze. Of course, you can still opt for the fire-resistive glazing if you’d like, but it may not be necessary depending on your building’s situation.

It’s crucial that you double-check with your installer about which type of glaze is required for your building to stay up to the relevant fire building codes, of which there are many. Whatever glaze your building requires must be based on these codes. We’ll be happy to inform you further through an inspection or installation
