Insulating lime render internal

The smallest bedroom in my Victorian terrace is really cold so considering upgrading insulation. Won't use any thick insulated plasterboards on external wall because the room is already small and will just start feeling smaller like a broom cupboard.

Walls are solid double brick with original lime render and gypsum multi finish on top. Can hack off the multi finish layer as much as possible if required.

Been looking at insulating lime renders and then may paper over with breathable thermal paper like wall rock. Would at least be little warmer than it is now without breaking the bank.

Any of the following any good for my plasterer to use? (Order of preference)

1. Cornerstone insulating render
2. Proof Shield ProofTherm insulating render/plaster

And any other recommendations under around £15 per square metre coverage.

As long as its breathable and I can paper over with wall rock and paint white (breathable paint) then I'll be happy.

Cheers.

I’ve just about to start installing wood fibre boards 40mm on job internally n then lime on top everything remains permeable

What will the total thickness add up to?

Really only willing to lose about upto an inch of floor space so these insulating lime renders and wall paper seems better for me. Don't need this to be the warmest room but anything will be an improvement over what it is now for a small budget lol

I think 75mm is equivalent 2mm of EPS ie with depth restrictions you at a dead end with that unless you're prepared to remove lime as well

Well apparently just 25mm coating of the cornerstone product gives an improvement in U value of around 40% for solid walls.

Can't remember tbf lol was going by a conversation with prooftherm a few years back. And advise you to bear in mind 40% of nothing is nothing so check in comparison to EPS
Anyway you seem keen to scrape off multi thus making mess , and accept that the lime is bonded well enough to slap another inch on top , all that trouble , mess and expense , I expect the spread to be on day rate with no guarantee

Cus he’s looking to do it on the cheap mate. He made me lose interest in helping him when he mentioned not breaking the bank and wanting it done for less than £15m2
Listen....quit making assumptions!!! I meant looking for a "product" that is around or less than £15m2. That does NOT include whatever my plasterer is charging!!

I’m not making assumptions you stated that you didnt want to break the bank and wanted something for £15m2 or less. Why not ask your plasterer what he recommends instead of coming on here to ask? Unless you already have asked your plasterer and he’s told you what you want you can’t do cheaply, or he’s just a shite skimmer who doesn’t know his arsehole form his earhole

I have the freedom to come and ask here for someones feedback and review of a brand or product that my plasterer may have well not used before...and you're not obliged to reply. Why don't you cool it off and stop crying...again another assumption "shite skimmer". All the best!

tek ode s**t off, treated batons up, 25mm kingspan in between batons then half inch board n skim hardly notice it come into your room and will be better than what you're planning on doing don't over complicate it n get on with it.
 
Would not suggest using a nhl lime base product on a Victorian house. Would certainly not advise using a nhl lime on top of a non hydraulic lime.
Would not suggest to wallpaper on new plastered lime ( unless you leave it about a year )
If your room is cold get a bigger radiator
