Door linings: narrower than the opening

[Post and beam]

Door casings ( linings) come in a variety of widths of course. When there isn't one the exact same width as the opening you need to line there is going to be a gap each side when the architrave is fitted flat to the wall.

So, what is the common practice to address this please?

 

I ahve been having all sorts of fun and games trying to find doors that the wife will accept that come in the right sizes for our openings. And then this issue of door linings rears its head as well.

you plasterboard right up to the lining, bridging the gap? i filled the gaps with foam once id shimmed the linings and then took the plasterboard bang up to the lining.

Plasterboard is installed and plastered already.  I think you are talking about a different measurement though.

 

for example, my door frame is 120mm from plastered face of wall to plastered face of wall. if lining is 115mm there will be a gap either side and if the lining is 125mm it will sit proud of the wall. Is it standard practice to plane to fit.

 

Obviously the best answer is to buy linings of the exact same width as the frame(& plasterboard)

Think a drawing may help?

Ah, so you mean wall thickness.. 

 

Mine was a couple of mm either side when I offered up the lining in the garage conversion, and I was tempted to fit it, then Architrave and caulk the gap..  I ended up trimming 5mm off the lining. 

 

Much better job

Buy linings that are wider e.g.132mm, and then cut them to the 120mm size you need. This is what I have had to do

This.

 

I would hold the lining in place flush one side then run a pencil using the wall itself on the protruding side to mark the lining for cutting. That way if you have walls that aren't uniform thickness it's taken care of.

Defo make the linings to suit each opening. Dont use ‘the nearest one’ as that’ll create a hell of a lot of unwanted and unsightly making good.

 

This is when a track saw becomes your very best friend. Hire one and make the job a breeze.
 

You can only go over-size obvs, so gap filling would be the only way forward if you want off the shelf stuff. 
 

👎.

Ah, depth, now I'm with ya.

Certainly cut that with a circular or track saw. Even a belt sander if you're careful enough. The track saw lets you plunge so that would work best now you're in-situ.

I have a nice dewalt circular saw. Can i use this  to cut say 5mm off of the long edge of pieces of timber   Linky thing

Id just draw my line on and rip that without a fence but yeah you could make a fence or get a track.

This is how I did it. Used my DeWalt circular saw. They came up a treat

This annoyed me on my first build, why does nobody make door liners to fit the actual width of a real standard timber stud wall and plasterboard?

 

On the second build they were all custom made and individually cut and planed to match the width.

If you only want cheapo softwood linings, Howdens do some useful sizes, like 115mm for 89CLS + PB
