Double storm panel on French doors?
I live in SE PennsylvaniaI, recently rather frigid winters.
I purchased a house with 13 South-West East facing exterior double french doors (26 doors in all) representing about 100' of wall space around a U shaped courtyard. Yes, I am aware that it is over the top, but I didn't build it - I just acquired someone else's mistake. Spectacular on temperate sunny days, but expensive to operate otherwise.
The doors are about 25 years old, in good shape for the age, single paned with a detachable storm pane with about 3/4" of air space between glass. Attached is a picture.
I need to get better energy efficiency and am thinking about adding a second detachable storm panel with another 1" of air space if it would give me a significant improvement. It would cost about $5,000 to do all the windows.
Replacing with new doors would be extremely costly, but I would be prepared to do as well it if it's the only course of action to get better efficiency and comfort, although I don't expect it would be much of an improvement energy-wise.
Appreciate your counsel on this-
