Fire door fillers

[LoterGarry]

Hi all,

We thank you for reading our post.

We have a fire inspection coming up in 5 days. When i did a fire door inspection today, the concealed door closers have been taken out. (This is going to sound bad but- they have been out the doors for over 5 years). Overhead closers have been fitted where required, and a concealed door closer in the cleaners cupboard. However, this means that the other fire doors have holes in them from the concealed door closers which have been removed.



So my question is What can i use to fill the holes in the fire doors, Please relate to the pictures provided .

I have found so far about: "
To fill fire doors, you can use the following materials:

Intumescent Foam: Specifically designed for fire doors, it expands to fill gaps effectively.

2
Expanding Foam: Suitable for filling large gaps during installation of fire-retardant door frames.

(SafeLink's site)

If anyone knows the best place e.g screw fix, that is cost effective please also advice.

Here is an example of our timber/wood fire doors, unfortunately i am not at the location at the moment so cant get picture of the holes

Assuming the doors are made from timber? You don't say the fire rating for the doors, assuming FD30? You don't say if the self-closers were removed from the top edge or vertical edge of the door?

You’re fine sticking with the overhead closers as long as they’re suitable for fire protection doors and the old pockets from the concealed closers are filled with the right fire‑rated materials. I’ve used fire protection doors from Fireresist before, and their guidance made it clear that inspectors mainly want to see consistent resistance, not the original closer style. Filling the voids properly should calm the nerves before inspection.
