I'm willing to be corrected but I'm fairly sure when a fire door is replaced, it has to be replaced as a set, frame and all. It is possible that the set the new door was taken from had the seals in the frame.

Then again it might not be a fire door at all. A blue roundel stating: "Fire Door - Keep Closed!" can be stuck on by anyone, fire doors don't actually come with them already fitted.

Just wondering has the door been painted as this can hide the strip - if it has only one coat is permissable in this as more will stop it working.

Interesting? On what do you base that statement? My estate is full of FD30 sets where the seal is in the frame instead of the door.

Or are you saying it's not a fire door because it hasn't been fitted properly?

SW,
Do you have access to a fire strategy drawing of that area?

With regards to recognising a fire door, I've known fitters peel the label off, hang the door upside down, plane that bit of the door! It may also be a two-tone plastic stud inset in the spine of the door.

Thank you for your replies

I don't have any drawings and it is not a job I'm working on - just sitting opposite it at another site and curiosity got the better of me!

The door "feels" solid, has BS1935 grade 11 hinges fixed and the correct glazing system.

However, it looks like a new door leaf (Wood finish not painted) into an existing frame. I cannot see any plugs or labels on the door indicating fire resistance, no intumescent strips on any jambs -even inspected the door frame where the new hinges have been cut out and no sign of strips, no strips under the door nor on the top of the door leaf.

So - can you still have a Fire Door without intumescent strips?!!

Thanks again

You have asked two questions. At the 1st post, you have asked, “Is it possible to have a Fire Door say FD30 that does not have any intumescent strips around the door itself or in the jamb?”

Answer is NO.

On your third post you ask “So - can you still have a Fire Door without intumescent strips?!!”

Answer is YES but only under specific situations:

FD 20 doors (without intumescent strip) can be accepted in domestic dwellings, although it is more usual for FD 30 doors to be installed these days.

FD 20s doors can be installed as sub dividing doors in corridors connecting alternative exits or sub dividing a portion of dead end corridor from the remainder of a corridor. However, when taking into account suffix (s), it would be difficult to demonstrate/provide evidence that the tolerances between frame and door is capable of limiting smoke leakage rate of not greater than 3m^3/m/hour. Again, it is usual for FD 30s doors to be used.



In the case of the door in question and from your description, it would appear that the installer has fitted a FD 20 door into an existing frame and has overlooked or ignored the requirement to control smoke leakage.
.

Have a look at the top edge of the door. If there is a certification plate that states fire door, FR or something similar it will be a fire door.

You may need a mirror?

Haha! :-)

Expect some odd looks when you take a make up mirrror out of you pocket! They're standard FRA pocket litter.

SW what are the markings on the glazing?

E30 is good, is there also BSEN 14449 and the name of the glass manufacturer? Is that Pyrodur?

It probably is a fire door but as it is new there should be a plate somewhere to confirm this.

It has been stated that fire doors should come as part of a complete door set, this is advisable but as long as the FR doors are installed by approved fire door installer? there should be no problem.

Take care

Try Part B building regs or BS 9999

Thanks to everyone for their replies and PM- appreciated.

I feel a little guilty actually as I thought there would just be a simple (If there such a term is with H&S) "Yes" or "No" answer and my question was not specifically related to a job I was doing!!

Great to see that there is so much help out there.

Thanks again
