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.
