A friend of mine has a new build house and has just had carpets fitted and
three doors cannot be shut due to the bottom of the door catching on the
carpets. The doors a 6 panel hollow type but are fire doors. He can see
the 'fire strip' on the sides and top but doesn't think (from what he can
feel) there is a strip on the bottom face. He doesn't want to take them off
until I get there next week!! Is there likely to be a fire strip on the
bottom edge and if so, can the doors still be trimmed (building regs)? I
presume so otherwise everybody that has them wouldn't be able to close them
after having carpets fitted! Presuming they have the stips is there
anything I should be pre warned about or can I trim with a saw etc. as I
would on a 'normal' door?

Cheers

Hello John

You will not find the intumescent (fire) strip on the bottom of the door so
you would be able to saw or plane in the usual way.

Yes but be careful the strips in the vertical edges aren't in a metal
housing.
Also be ready for the weight when you take a fire door off. They're
heavy.

No strip on the bottom, and often none at the sides either

(you can avoid the need for side strips if the door stops on the frame
are at least 25mm deep).

The door should be trimmable in the normal way.

They are 'kin heavy!

No longer the case. The old 1" door stops do not contribute to the
fire resistance of the door due to the different way fire doors are
now tested.

The requirement within dwellings is for a 20-minute fire resisting
door. Some BCOs will accept an FD30 door without intumescent strips
as an FD20, but strictly speaking, unless a door has been tested to
BS476: Part 22 (1987), no period of fire resistance can be guaranteed.
Very few, if any, manufacturers will test their doors without an
intumescent strip to 20 minutes (it's expensive, and the market for
FD30 doors is greater, so why waste money testing a door to 20
minutes).

Does that mean that if you fit FD30 doors you no longer need to use 1"
stops? Or do you need a FD certified frame as well.

1) Correct; you no longer need to use 1" door stops; AND
2) The door and frame come as one tested item; mixing and matching may
invalidate the test.
