Internal Insulation of solid walls (Ed.)

[ThisoldhouseCoalport]

Hi everyone,
I have a very old house. Around 1830. I've took all the plaster off the internal walls and have battened all the walls. Floor to ceiling. Nothing is attached to any of the brickwork. Could anybody advise me on the best insulation to use. The outside is brick no render. And it's single 9" brickwork.
Thanks in advance.

Can you confirm the size of the battens/studs? Are they 38mm CLS timber?

Hi, they are 3x2. C24 battens.

Thanks. Did you consider putting foam backed plasterboard on the walls?

Now you have battened them, you can put 50mm kingspan PIR insulation in all the gaps. Foil backed plasterboard on top with all joints sealed meticulously to stop vapour getting behind.

Thanks so much for the information. I'm a newbie at this so have YouTube to thank for the battening. Enjoyed doing it tho. Thanks again.
