<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'>Does
anyone have any rules of thumb on a quick/easy approximation for taking a
Center-of-Glass U-value and converting it to an Assembly U-value based on
industry standard assembly constructions? I know this depends on a lot of
variables, like frame material and conductance, and the size of the overall
glass assembly, etc., but I’m just looking for a quick estimate on
performance reduction for comparisons to other window types for a particular
building.<o:p></o:p></span></font></p>
