Three types of fire door foam Multifix supplies – and what they do
Given its importance, one of the more common questions we get from carpenters is, “What fire door foam do you stock?”
Required by law, the use of fire door foam allows occupants vital time to escape a burning building safely.
But which one is best for you? If they all do the same thing, what makes the ones we stock any different?
At Multifix, we stock three different types of fire door foam, with all three proving to be very useful for carpenters.
In this article, we will go through the three types of fire door foam that we stock and explain why they are different and how they can help you.
Blue60 Intumescent Fire Foam (750ml)
A very reliable fire door foam, the Blue60 is one of the first properly tested fire foams for fire doors. It is a self-expanding fire foam and is also made up of environmentally friendly propellants, which stop it from burning into the ozone layer.
Providing up to 60 minutes of fire protection, the Blue60 has been tested in pretty much every possible combination of frame and wall materials.
It is to be used in conjunction with Blue60 fire-rated packers, which come in three different sizes. These are 1mm, 3mm and 5mm in thickness.
The polyurethane foam is ideal for sealing applications wherever fire resistance is required and also conforms to BS EN 1643-1 and BS476 Part 22.

Fire Door Foam for Fire Doors & Doorsets – Gun Grade (750ml)
Next up is the Fire and Acoustic (FAS) foam, which also offers up to 60 minutes of fire resistance, but it has also been tested with plastic packers.
This does give it something of a unique advantage, as it can be used with both plastic and timber packers.
The FAS fire door foam is suitable for use for cavity gap filling, perimeter pointing around fire doors, MDF, timber frames, softwood and hardwood.
It also has BS 476: Part 20 & 22:1987 and BS EN 1634-1 accreditation and has an acoustic rating of up to 60 dB Rw.
In addition, the FAS fire door foam has CF5839 Certifire approval and very much offers an all-in-one solution.

Nullifire FF197 Fire Rated Expanding PU Foam – Gun Grade (750ml)
Finally, we move onto the Nullifire FF197 fire door foam, which is used to seal linear gaps throughout the fire-rated areas of a building. The Nullifire FF197 can also offer up to 240 minutes of fire resistance for linear gaps, while up to 60 minutes for fire doors.
It can also be used to seal door frames and window frames and can fill gaps of up to 35mm when being used for a fire door.
Like the FAS fire door foam, it can be used with plastic packers, but it has also been tested without architrave. The foam itself is pink, which is great for the installer as this makes it easily identifiable against other types of expanding foam that aren’t fire-resistant.
The FF197 has also been tested to BS EN 1634-1 and BS EN 1366-4 and can also offer an acoustic rating of up to 62 dB.

A fair selection of fire door foam
While all three types of fire foam have their own unique differences, the main objective is the same – providing up to 60 minutes of fire resistance.
As mentioned earlier, this can be the difference between safety and disaster, so it’s imperative that whatever fire door foam you use, it is applied correctly.
With these three types of fire foam, you will be ensuring that properties are kept safe. Lives could be saved as a result of these foams, which is why they are so vital.
These three especially will be used up and down the country for a number of different sites; and with very good reason. They all have their own unique characteristics, but they all serve the same goal and do it very well.
If you need something versatile, then the Blue60 won’t let you down. If you need something that is fine with plastic packers, then the FAS foam is a great shout. Equally, if need something that can work without architrave, then the Nullifire foam will be a good fit for you.
