ᐅ Insulation for the base slab / foundation

Hello,

I took some thermal images of our house and noticed that the foundation appears quite warm in the pictures. The house is a prefabricated timber frame home built in 1980, with underfloor heating and no basement. Is it normal for the concrete slab to be this warm when using underfloor heating, or can it be effectively insulated afterwards?

Also, apart from the slab and the two very bright windows (which still have the original single glazing), do you see any other areas that could be improved?

Thank you very much for your help in advance!

No, you probably have a thermal bridge. The floor slab might not be insulated...

Difficult without major work.

Honestly, the pictures are quite small. I can’t really make out much.
