Glazing Properties:
Glazing materials for the purpose of simulation has been adopted from the PPG catalog. PPG being on of the possible partners for the project, it is best to use real data from the manufacturers for the purpose of simulation to get results closer to reality in terms of glazing effects. The table below describes the glass name used for the renovation of Donner house with the type of window frame. �
