Is an oak threshold permitted under a fire door?

[Guest Julia Hammond]

Hi, we are fitting a fire door between our garage and our boiler room. (The boiler room is attached to the house and has a back door leading from it; above the garage is a bedroom.) Can we fit an oak threshold beneath the fire door under current regulations so long as the gaps are correct? Thanks for your help.

Yes, Oak is a good timber for a fire door threshold.
