To be frank, I’m not sure if replacing the single pane with double pane is: A - something I can afford at the moment and B - something I can DIY (which adds to point A).
I have a feeling that the windows are a large part of my electricity usage (due to AC constantly running), I have them “foiled” and really tempted just to board them up. Before I go to that extreme, I was thinking maybe there’s something I can attach to the outside that would essentially add that 2nd pane, or at least block some sun from hitting the glass.
suggestions?
Windows are usually towards the end of the list of things to upgrade. What’s your insulation situation like? Attic, walls, ductwork? Have you done a leak test to see where conditioned air is escaping? Has your AC been serviced and in good operating order?
I’d check all those out before replacing windows. As other poster suggested. Especially if you have windows that are in good condition otherwise.
