Hi all

I have just been asked by a surveyor to take off additional hardwood lipping from a fire door and close the gap by adding softwood lining to the door frame as it looks more aesthetically pleasing. Logically I assume it would be better to have a firecheck hard wood lipping on the door rather than building out the doorframe with more softwood? 

 

 

What do you man additional hardwood lippings?

Using thin pieces of timber to add thickness to the inside face of a door frame or to the edge of the door leaf is not a suitable repair (to a fire door) when trying to reduce the gap between the door leaf and frame.

Where the gap is so large that it cannot be reduced by adjustment, either:

1) Loosen the door frame jamb, pack behind and fire-stop between frame and wall accordingly. So as to reduce the overall width to suit the door leaf.

2) Remove the existing hardwood lipping form the door leaf and fit a replacement hardwood lipping thick enough to reduce the gap. Lippings should be generally min 6mm thick to a max of 18mm

I assume suitable intumescent seals are fitted?
