The Glass Database Chart displays glass types and their relative positions to each other. This Chart may be filtered by the sliders for SHGC/SF, U-value and VLT. An orange dot will indicate the current glass type selected in the main list. In this way, the properties of each glass type are presented according to the axes of the Chart. It can easily be seen if there are better performing glasses than the one selected.
This is covered later under Section 7.3.7 Glass Database.
