Glazing Components

There are 2 ways to enter Glazing component data depending on the Definition method setting:

1. Simple - the glazing properties for the overall glazing system are defined using summary U-value, Solar Heat Gain Coefficient (SHGC) and Visible transmittance (VT) data. This approach is recommended when only manufacturers summary glazing performance data is available or where only whole assembly glazing data is available. If more detailed data on the constituent panes is available then the more accurate Layers method should be used.
   
   
2. Layers - where the properties of the glazing component is defined in much more detail through selection of a number of glazing layers (Panes) separated from each other by window gas layers. In this case there are two tabs on the Glazing data dialog:
   
   
• Layers where the glazing panes and window gas layers are entered
• Calculated where derived calculated data on the glazing system is displayed

Glazing component data can be accessed:

• from the Components tab on the opening screen (to view/edit library components if no file is open),
• from the Components tab in the Navigator panel (to view/edit model components if a file is open),
• by double-clicking on the glazing icon on the Openings tab in the model data,
• by clicking on the Edit button when selecting glazing components from a list.
