Hi, I have been following the forum for a while now but this is my first post.
I have a 1900’s house that I am starting to refurbish. The walls are solid and externally rendered. I plan to insulate the external walls internally with kingsman K17 or similar at circa 60-70mm thick boards. My question is what happens at the window junctions. Do I board under the window boards and reveals? This would seem logical so as not to have cold spots but the window can’t accommodate a 60mm build up to the frames surely.
