Since the wall insulation of buildings and the quality of glazing improve more and more, the window frame becomes the weak point in the facade from a thermal perspective. This paper discusses a new frameless window construction. Results in this paper show that the best position of the glass is in the middle of the insulation. This new junction has an almost 40 % lower energy loss compared to a traditional junction. Computer simulations as well as experimental measurements of a full-scale prototype have proven this.
