The list may be filtered by using the sliders provided. Filters are available for U-value, SHGC (Solar Heat Gain Coefficient) and VLT (Visual Light Transmittance).
As the filters are adjusted, only Glass Types which have properties within these ranges are displayed. You may use one or more filters to filter the Glass Database list. If multiple filters are used, only glasses that are within all the filter ranges defined, will be displayed. You may then select one from the shortlist to apply to a Surface on the model.

Performance Sliders
These are related to another function which will be explained later. These relate to target values for selected Surfaces and glasses that may achieve these targets will be suggested.
