Insulate exterior wall of expanded clay concrete blocks above ground - interior?
Hello!
I have tried to find a good answer here on the forum, but I haven't found what I'm looking for.
We have built a stable and in it, we have a room (saddle chamber), which is to be heated year-round with an oil-filled electric heater (about 16 degrees).
Exterior/interior walls are 190mm leca.
I plan to plaster/slam them on the inside and then attach 45mm steel studs flush.
On the inside, I want 12mm plywood to be able to conveniently attach saddle racks/other heavy items.
The questions are:
1. Do I need to insulate the space? Will the electricity cost skyrocket if I don't? (which I believe)
2. If I should insulate, should I use mineral wool between the studs?
3. Should I have a vapor barrier between the steel studs and the plywood?
Where we live, there are occasionally days when it gets down to -15 degrees, but usually, it's at most -5 degrees in the winter.

Addition:
We will insulate the ceiling between the rafters (195mm wooden beams).
Above is a straw/hayloft.
Is it enough to just throw up insulation between the rafters and then put up a ceiling? Should there be a vapor barrier between the rafter and the ceiling?
/Best regards

Wouldn't it be possible to have foam plastic between the steel studs? It insulates well and withstands any moisture. For the ceiling, I suspect you need to install a vapor barrier when you want it to be that warm inside and also have straw/hay in the loft.
Foam might not be a bad idea... but do you think you need a vapor barrier or not? =)
Edit:
The downside of foam as I see it is getting it to seal tightly against the studs, which means there might be some thermal bridges between the stud and the foam..?
If you have mineral wool, you might be able to press in an extra cm/add two thinner layers and overlap...?

I have never built with metal studs, but I know that foam can be used in combination with them. Is it not possible that the board can be inserted into the stud? The stud is just a thin metal. Maybe it's a good idea to go up in size to 70 mm? I assume that foam insulates better than mineral wool, which might be needed when the wall is only built with 19 cm leca. In the ceiling, you need a vapor barrier, and if you use mineral wool, I assume you need it in the wall as well. Personally, I would have used foam for the wall without a vapor barrier.
