[Bldg-sim] Frameless Windows

[mark dewsbury]

I second Chris Jones's comments. 

Whether the glazing is single or double, there will be regular joints in the
glazing which do produce edge affects. Some infrared images I have taken
show some very interesting differences, to the worse, between the basic
physical models and what really happens in a window.

I believe there will still be edge effects to take in to account.
