90-Minute Fire Rated Doors – The Full FAQ Guide

In this guide, you will find the most relevant and up-to-date information about 90-minute fire-rated doors.

A number of the most basic and useful questions will be covered in great detail.

The questions covered include how a 90-minute fire-rated door is tested, what materials are used in its manufacture, the regulations that you should be aware of, and more. 

90-Minute Fire Rated Door

What Is A 90-Minute Fire Rated Door?

A 90-minute fire door is internationally known as an FD90 certified fire door.

90-minute fire-rated door assemblies are shipped with a certificate and special labels providing the information about all required characteristics.

Any building regardless of the size must have a passive fire protection system.

One of the most important elements of this system are correctly installed and functioning fire doors.

90-minute fire-rated doors are made to be able to stay intact during an event of an actual fire during a fixed amount of time (in ideal conditions 90 minutes).

The main function performed by the fire doors in case of a fire emergency is to provide localization of fire in the area of its origin or minimizing its spread giving time for evacuation.

Durable fire doors also mean that in case of fire less damage is suffered by the property and assets, and more people can leave the building safely.

On the other hand, fire doors of poor quality or the absence of them can mean huge losses and put the lives of the people in danger.

Fire safety is a mandatory part of the design requirements of the local, national, and international building regulations. 

The regulations provide important instructions about how those standards can be incorporated into a specific building project.

FD90 fire doors are among the most durable types of fire doors presented on the market nowadays.

They are mostly applied in the settings that are specifically required to have such level of fire protection or if extra safety is a must.

Fire risk determines the need for a certain fire door with a certain rating and it depends on many factors.

Like for instance, the probability of a fire occurring, the structure of the building, its purpose, the materials used in the construction, the nature of its business, and so on.

Only after being completely sure that the fire risk assessment is performed in a sufficient manner will you be able to make an informed decision concerning installation locations of 90-minute fire-rated doors.

It is advised to seek professional consultation beforehand.

The main difference of a fire door from a normal door is its ability to withstand fire and smoke and the certification which proves this as well.

More about how a fire door is tested to determine its rating down below.

How KDM Tests 90-Minute Fire Rated Doors?

Before a door can be labeled as the 90-minute fire-rated door it first must pass a number of tests.

Only after rigorous testing can a door be certified as the 90-minute fire-rated door.

There are numerous testing laboratories and facilities around the world, some of them like UL are of international level and are issuing certificates accepted worldwide.

Some are only providing country-wide accepted certifications.

But regardless of the specific laboratory or testing facility, the basic procedures used to determine what specific rating should a door have, are the same.

Each test is required to be performed on complete door assembly.

In other words: the fire door and doorframe and all the hardware supplied (locks, latches, hinges, self-closing mechanism, and so on) are tested together as a fully functioning prototype. 

This is due to the fact that if different parts are tested separately there is no way to determine how well a complete assembly would perform in a real-life situation.

To push the real-life emulation even further, the whole door assembly is attached to a special wall and is tested in different positions. 

It is important for the actual door frame to be tested as well.

The test procedure in the full version can be found in the book of standard testing procedures of the specific laboratory. 

The basic steps of the testing procedure include, but are not limited to:

  1. Both sides of the door being exposed to the fire in a controlled environment.
  2. The door is observed carefully for integrity by the professionals.
  3. The time-temperature curve is applied to visualize the performance of the door under specific fire conditions.

Generally, the standard testing procedure requires the tests to be performed with the upper part of the door under slight positive pressure, in order to simulate the conditions observed in a real-life fire emergency.

After the door had passed the FD90 test every door and doorframe manufactured according to the same prototype as the one tested will have the same fire-resisting properties and labeled FD90.

The identification label indicating the fire rating of the door can normally be found at the top edge of the door.

A plug with color code is sometimes inserted into the door as well, instead of or as an addition to the label.

Sometimes the identification marks are removed, damaged, or painted over during the installation or adjustment of a fire doorset.

This unfortunate situation can be avoided if the work has been done by a professional fire door installation service.

How To Prepare Surrounding Wall For A 90-Minute Fire Rated Door Installation?

The installation procedure is crucial, so doing it the right way is of paramount importance.

One of the first and foremost things to take into consideration when installing an FD90 fire door is the characteristics of its surrounding wall.

Since an FD90 fire door is generally heavier than a normal door you should check beforehand if the surrounding wall is able to bear the additional weight.

So pre-check and inspection of the wall should be your priority.

The door frame needs to be securely attached before you can start to install a 90-minute fire door.

Make sure there are no spaces between the wall and door frame.

If you spot any spaces, close them.

If you have to close more than six spaces on both sides of the door, consider installing a new frame before proceeding to the next steps.

One of the last steps before completely installing the door is measuring the frame to make sure that it is wide enough to incorporate the full length of the screws.

Then the hinges must be fitted to the door frame.

How Often Should I Inspect Conditions Of A 90-Minute Fire Rated Door?

Professionals recommend checking your 90-minute fire door once a year.

It may be advised in some cases to check your FD90 fire door even more often, depending on the weather conditions it is exposed to and the use intensity.

The material of which the fire door consists is a key factor when considering how often the door should be inspected.

The veneer, fore example, is not the most durable material, the wood is more solid, but the metal is among the most long-lasting solutions.

If your FD90 fire door has many hardware items installed, and on top of that it has many extra moving parts, you should pay more attention to them.

Every country can have its regulations for fire door inspection procedures and demands, be sure to consult your local law bodies.

A professional inspection is, of course, a must, but you can easily do some minor checks of your FD90 fire door yourself.

Pay attention to these points: inspect for any missing or broken parts, check for any visible signs of damage, be sure that the label or the color plug is clearly visible.

If your 90-minutes fire door has any glass parts installed, check if they are without damage and are securely fastened in a designated place.

A self-closing mechanism of a 90-minute fire door can be easily inspected: the door must close completely by itself when fully opened.

The revised standard is applicable only to door assemblies that are designed to provide fire resistance ratings of up to and including a two hour time period when tested in accordance with other British standards BS 476-22 or EN 1634-1, BS 8214.

90 Minute Fire Rated Entry Door

Should I Use Intumescent Strips With A 90-Minute Fire Rated Door?

An intumescent strip or seal is specially designed to expand during sufficient heat exposure. 

It functions by filling the spaces between the door itself and the door frame.

An intumescent strip or seal is not required for some fire doors composed of certain materials.

Intumescent seals or strips, for example, are not required to be installed on FD90 fire-rated doors made of steel, since the basic properties of steel are its capabilities to expand when exposed to heat.

Intumescent seals are generally used for smoke and fire barriers on FD90 wood doors.

Depending on the material of the door different types of care are needed.

For example, if your FD90 fire door is made of wood or has some wooden parts in it, you may need to refinish it from time to time to maintain the best possible appearance.

On the other hand steel door does not require this type of care.

Residential 90 Minute Fire Rated Door

Where Can I Find Regulations And Guidelines For A 90-Minute Fire Rated Door?

The regulations vary from country to country.

NFPA (National FIre Protection Association) is a good international reference for regulations concerning FD90 fire doors.

NFPA codes and guidelines are applied to the complete door set as well as to its parts, like for example hardware or door frames.

In the US, NFPA standards are used alongside with building and fire codes, however, these standards mostly come from the NFPA documents and are adopted in different proportion from one state to another.

Thus, if you are an American citizen, we advice to contact your local building authorities to clarify what kind of regulations they use in the case of fire doors.

Speaking of the UK, things are more unified.

In particular, you have to look at documents published by British Woodworking Federation and British Standards Institution.

Also, the UK Building Regulations (Part B) consist set of rules for fire safety systems in all dwellings.

These rules include regulations for fire doors.

In the European Union, there is a convenient unified standard EN 16034.

It refers to all fire-resistant and smoke control devices, including fire doors.

90 Minute Fire Rated Door In School

Does The Hardware Used With A 90-Minute Fire Rated Door Have A Fire-Resistant Rating?

Yes, in order for a fire door to have an FD90 rating it should have all of its hardware FD90 rated as well. 

This requirement applies to standard and custom hardware alike.

The hardware supplied by KDM includes hinges, locksets, levers, handles, and knobs.

Push bar panic and fire exit devices, FD90 fire-rated closers, thresholds, door bottoms, hinges, and builders hardware accessories.

The hardware used for FD90 fire doors undergoes rigorous testing and complies with all the necessary standards.

Be extremely attentive when changing your 90-minutes fire door hardware and accessories.

Since if one of the door’s parts is changed, for let’s say FD30 or FD60 analog, the complete door assembly will lose its fire rating and will no longer be FD90.

Generally, if you use professional fire door installation and maintenance service you can avoid this kind of situation.
