I used 27mm insulated plasterboard. @Onoff do you think this worked for you? I was thinking about doing something similar. Like you, I have some (15 year old but still) decent windows but they are fitted close to the edge of the external leaf rather than across the cavity.

I have a similar issue (I can see it in cold weather with a Flir camera). Could it help just to put internal or external insulation in the corners or would I have to insulate the whole wall?
