FD 30S

With a FD 30 fire door with an Intumescent strip it is not necessary to do the bottom of the door (http://www.search-document.com/pdf/4/3/frg-100.html#).
Is it necessary with FD 30 S to do the bottom?

I'll answer this as a boards poster instead of as a professional. But most FD are not sealed at the bottom and I've seen large public building with alarm activated fire screens that don't have to be sealed at the bottom.

It's nature that smoke will rise so by the time it starts escaping through the bottom gap then the room has already filled with smoke.

Thanks, that would be logical. I have intumescent strip fitted all round my doors and someone just pointed out that FD 30S means with a brush. If I don't need the bottom doing it would make changing the strip a lot easier.

Got surface mounted seals that fit round the door frame with brushes and very good they are too.
Another problem: my 3 bathrooms have wood cladding on the walls but as they are part of a Protected staircase I have to remove the wood or fit Fire doors. The doors are old panel doors and I am reluctant to remove them. Any ideas?

Thanks for that. We fitted fire hinges on the panel doors as we plan to use the product from Fireseal to do the panel doors. The problem is this: The front the house is 5 meters wide and tapers to 1 meter wide internally. As I say it's an old house. The last rooms are the bathrooms which are about 1.90m. wide tapering to 1.m. and 4 meters long. So the doors do not open to 90 degrees.(I have problems attaching photo using Safari).
Fitted the hinges but cannot give them enough tension to close the door as we do not have room behind the open door to get at them
In one bathroom we have plastic sheeting(Fire class A) on the walls with wood paneling on ceiling.
Another bathroom we have wood panelling on the walls and Duma Sheets(Fire class 1) on the ceiling.
3rd bathroom is all wood paneling.
What would be involved in painting the wood? How long does it last.
Bit worried the Engineer would not sign the Fire Cert.

Contacted Fireseal and said I wanted material for 2 panel doors but they replied that to do not sell to the public or trade and the doors would need to be done off site!
Anybody else do this treatment?
