Insulation for tile hung house?

[MrsKateColumbo]

Hi all,
My house is 1930s, originally most of the 1st floor was tile hung, most of that has been replaced by extensions hut there's a 4m wall along DD's room that remains.

There's a stud wall then I think nothing, then just tile basically. Has anyone insulated in similar circumstances? Ive read online and I think i should insulate the stud wall vs the tiles for damp reasons (ie i think the void/eave needs to have cold air?).

I also need to have the window sorted as air is coming in there too but the tile wall seems much colder than the other external walls.

Thanks

This isnt my house but this is what i mean by tile wall.

The roof is original, i also have a tile hung (smaller) wall on the extension but that's much better insulated some how

You could use insulated plasterboard on the inside so you can keep the tiles on the outside.

Thanks

Yea, you need the void.
insulating cork board would be a good place to start.

Can you get into the void to see what’s there? Very often the tile hung walls are just a timber frame with tiles outside and plaster inside. To do it properly, you need to strip it off inside completely then go from there. The alternative is just go over the wall with insulated plasterboard.

The long wall i can't get inside (and part of it is a chimney breast which complicates things) but the other side there is a tiny bit left of the old eave which i can get into, and yes it is literally just timber (there was a bit of polystyrene insulation as well)

"there was a bit of polystyrene insulation as well"

that needs to go or it will cause damp

Thanks, I got most of it out of the side I can access but im slightly concerned there's more on thr longer side. I guess ill have to cut a hole!
