Removing storm/screen door
I'm not sure in which forum to place this question.
I have an older home (60 years).
I would like to remove the screen door at the front because it's ugly and it makes it hard to get in and out when your hands are full. I don't need it for ventilation in the summer. There is a small, open landing outside with a roof.
The entrance door is solid wood with three narrow windows in the upper third. The door closes tightly and has weather stripping.
My question is that, given the above, how much value is the screen door in terms of added insulation (by trapping a little warmer air between the wood door and the screen door in the winter)?
