Door Lining intumescent

[hamd01]

I've recently installed a door lining kit from b&q. I'll be honest, getting it plumb perfect took me near enough 5 hours.

Having never installed one I didn't wonder why there was a groove on the entire length, both sides and across the top. Included in the kit are 3 thin strips of wood that fit in the groove.

I wondered if it could be a intumescent housing. I didn't order a fire door lining, so bit surprised... and I guess if it was an intumescent housing it wouldn't come with inserts.

Can anyone advise, as I'm worried that I can't quite understand how this groove will be concealed

The strips sound like loose stops for the door

It sounds like you purchased a fire check door frame, eg

If so, the grooves are for intumescent strips. The thinner bits of timber are the door stops (the timber against which prevents the door trying to exit via the opposite side of the frame).

Not really sure how to advise you further- sorry. You could fit intumescent strips and then paint over them but they will still be slightly visible. You could backfill with 2 pack filler but that will require a lot of sanding and in time it will become very slightly proud- although after the second sand it is less obvious.

Two pics here which hopefully demonstrate. Pic one with the wood inserted into the groove, and pic 2 showing the groove.

This was the product I bought... Here https://www.diy.com/departments/met...or-lining-set-h-210cm-x-w-13-2cm/73550_BQ.prd

That's what I thought to be honest..just not sure how these are covered with the architrave....hopefully the pics make sense.

Cheers. What I don't understand is if it's for intumescent strips, why have they included wood to fit into the grooves. Hopefully the pics make sense.

Looks like you have completely misunderstood how a door lining is assembled , and your link is faulty .
You can fit the sides back to front to lose the rebate for strip .
The thinner section fit flat to door lining not into groove.

It's seems increasingly difficult to link to B&Q, I daresay it's messing with DIYnot's advertising.

It is just a coincidence that the door stops fit in the gaps.

Some links seem to go via an affiliates program (Awin.com). Others don't.

Gottcha yup makes sense. Actually fitting these door stops flat, covers the gap anyway....so I dont think I have an issue.
