Obscured glass entry door and solar heat gain
This is a weird question, but who else would I ask, but all of you. I want to know if there is privacy glass that still offers decent solar heat gain, and if one type is better than another.
The front of my home faces South and also faces the street on a city block. I want a glass entry door for natural light and solar heat gain in the winter (yard is shaded in summer) Provia makes Quad pane doors 2.5″ thick that seem like they might fit the bill with U values as low as 0.13 (the same as my windows, coincidentally): http://www.proviaproducts.com/productdetail/entry-doors/embarq-glass
My issue is that my wife insists on obscured / leaded glass for the door, which seems to kill any chance of solar gain. Is there such thing as a privacy glass that allows a decent amount of solar heat gain? I can’t even find any testing that has been done on privacy glass for SHGC.
