In traditional designs, the exterior windows are centrally located in the structural wall, and the exterior openings of the windows are treated with an additional portion of insulation materials with high thermal resistance to prevent cold bridges. Due to the small scope and simple construction methods, the heat transfer coefficient at the window is large and the air tightness is poor. The installation methods of doors are similar.
