The 'Normal hemispherical transmittance’ calculated this way (0.553) is different from Tvis( 0.453) calculated using Window, for the same combination of glasses (the case of 8905 and CARDINAL_66_0.76.rad, shown below). The only thing extra in Window is air gap (mix of Argon and air).

I generated a db with Clear-Float-Glass-8 initially (see the Supported surface types above) and then another db after removing it (see below). It still generated db, but when using Glaze script, I see  a 1 - clear glass is generated in Supported surface types automatically. In both cases (above and below) i get same Normal hemispherical transmittance. Is it ok to use any clear glass here?
