Dual pane window infrared….normal? – GreenBuildingAdvisor

Greetings all,

We’ve just finished building a home along the So Cal coast, and are surprised at how cold the house is. As a longtime follower of this site and others, I was diligent about air sealing (10 cases of caulk, 25+ cans of foam) and ended up re-doing at least 1/3 of our insulation myself because the subcontractor was so sloppy. 

Any by “cold” I mean the temp will say 74-75F, but it feels like 65F the moment the FAU shuts off. We’re going to do a blower door test soon. I’ve walked around with a FLIR and while our (many) IC recessed lights are clearly offenders (10F colder than the room), I don’t see any large likely air leaks or cold areas. 

That brings me to glass. I’ve attached an IR pic of a window. Interior temp was 72F, outside temp was 50F, center of glass 65F, and the edges were mid 50F range. Is this normal? 

Thanks for any insight.
