The insulation is usually applied on the outside of the building so the protected volume is more homogeneous, avoiding cold bridges where walls/ceilings join, cause that’s where mould tends to grow
In all the new build houses I’ve worked on the insulation is on the inside, in the UK at least. Though it’s been at least 10 years since I’ve been on site.
Also usually external insulation is quite visible and I still see lots of domestic properties with bare external brickwork.
That’s interesting. In Germany and Belgium many renovations involve putting insulation (PUR blocks often) on outside of the building and also for new buildings it’s usually outside insulated and then an outside layer that protects the insulation. Inside insulation happens, but it’s considered less good than outside, because of leaks and they say outside insulating helps the bricks/concrete “save” the heat like a battery when they are part of the protected volume instead of outside of it.

It might be the UK is hampered by our lack of space … Outside insulation sounds like a good idea.
There’s a govt funded insulation of cavity walls scandal that’s playing out now.
