VisibleRefractionIndex P_SINGLEVALUE / IfcReal
Visible Refraction IndexIndex of refraction (visible) defines the "bending" of the sola! r ray in the visible spectrum when it passes from one medium into another.
SolarRefractionIndex P_SINGLEVALUE / IfcReal
Solar Refraction IndexIndex of refraction (solar) defines the "bending" of the solar ray when it passes from one medium into another.
GasPressure P_SINGLEVALUE / IfcPressureMeasure
Gas PressureFill pressure (e.g. for between-pane gas fills): the pressure exerted by a mass of gas confined in a constant volume.
