<p class=MsoNormal><span style='color:#1F497D'>Serious Materials provides full
frame performance data here: <a
href="http://index.seriouswindows.com/document-library/Datasheets/">http://index.seriouswindows.com/document-library/Datasheets/</a>.
I have also have some of our commercial packages modeled in curtainwall and
storefront framing systems that I can provide upon request.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>Firstly let me say that Window5
is a great tool – I use it often and love it. The only thing I would
advise is that there can be a wide distribution in frame U-factors. The default
U-factor for a thermally broken aluminum (TBA) frame in Window 5 is U-1.0. Using
THERM and Window5 I’ve seen TBA frame U-factors vary from as low as 0.8
to as high as 1.5. The resultant full-frame U-factor using these 2 differing
TBA frames (and the same glass package) is: 0.29 (R-3.4) for the poorer
performing frame, and 0.22 (R-4.5) for the better frame.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>I would say that putting either
of those full frame u-factors in your energy model will yield pretty different results.
<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>I think it’s really important
that we, as simulators and modelers, look at full-frame performance because
this is the system that will be installed in the building. Center-of-Glass data
can be useful comparing two different glass packages, but at the end of the
day, it’s a framed system that will be installed and a framed system that
should be analyzed. My 2¢.<o:p></o:p></span></p>

<p class=MsoNormal>Does anyone know of a window manufacturer web site that has
literature on its windows including the frame? I am using Trace 700 for EA
Credit 1 and the reviewer asked for manufacturer data sheets for window
performance values (U-value, VLT and SHGC) including the frame. <o:p></o:p></p>
