The analysis was performed in the Window 6.3 program developed by the Lawrence Berkeley National Laboratory, which has the possibility of a comprehensive analysis of the heat flow through the various types of windows, according to the current assessment procedure developed by the National Fenestration Rating Council (NFRC) and comply with ISO 15099. For the purpose of the analysis a number of computer simulations of various window frames were conducted.
