Why not stack windows in a thick wall?
I’ve been contemplating window details for a thick wall assembly, and reading about “innie” vs “outie” windows.
That leads me to wonder: why don’t people put two windows into the same opening? What not an innie and an outie? Wouldn’t that allow for the use of cheaper windows, while achieving higher r-values?
I’m sure I must be missing something, and there’s a good reason this isn’t done, but I can’t think what the reason would be.
Can somebody educate me on this?
