Hi Nicolas,<div><br>That is a really strange result. I checked glass code 2662 and if you look at the LV-H report in the .sim file, it looks like the COG U-value is 0.233 Btu/(h-ft²-°F). That matches a similar glass I created in Window6, (dual-pane argon filled w/ surface 2 e~0.04). So while the input value looks wrong, what's being simulated and reported in your .sim file look right.</div>
<div><br></div><div>As a comparison - a dual pane w/ argon and no Low-E in Window6 has U-value around 0.45 Btu/(h-ft²-°F).</div><div><br></div><div>Hope that helps.</div><div><br>Cheers,</div><div>Alex<br clear="all"><p>
