Performance of Incorrectly Installed Windows
I have 10ish year old Andersen Single Hung 100 series windows with Low-E and SmartSun coatings.
I realize these are entry level, but they seem to have decent infiltration rating – energy star for northern climates if the prev owners had sprung for
I had an energy audit, and the auditor mentioned something in passing about my windows being installed wrong. I don’t remember if he said anything specific, and haven’t been able to follow up with him.
The windows face due south with direct sun just about all day in the winter. I took this thermal image one a day that was between 40 and 45 out.
Does anyone have any ideas what the inspector may have noticed from his thermal images? Is this expected performance for these windows? What can I do to improve them?
I have caulked interior and exterior trim with BigStretch. I’ll probably end up putting the heat shrink kit on and see how much that does, but not sure that will make a lot of difference on pretty new windows?
