My builder has put in my windows and left space in the reveal for 47mm of insulated plasterboard to the left and right of the window. But he has not left room at the top underneath the lentil!
Can anyone recommend an insulated plasterboard that is really slim - up to 20mm wide. I do not want condensation/mildew on the underside of the window lentils. Nor do I want to ask the builder to tear the windows out either, he is very good otherwise.
