What swings inward, the current window or the storm/screen? Are the windows wood or steel? Pictures? Do you currently have any storms & screens you could take a picture of? Help us help you.

There are no current screens. The storms are on the outside. The windows swing in and are made of wood and are the original 100 year old windows. I will get some pictures, Thanks

You could by an aluminum storm that has an screen and glass panel you switch out.You could also do a double hung or slider that woukd allow you to leave both in place. These styles would not allow full venting and would impede on your sightlines. You could also buy or make some screens with a wood frame ti switch out with your glass ones. I would check local lumber yards if plan on installing your self.

French inswings probaly leak more air than any other style of window. and are kind of impractical.

I would be more inclined to replace them altogether.

There isn't money in the budget to replace all the windows at this time, but the thought was to gradually do that. Love the look of these windows as well, but I agree that they are not practical.

Thanks for all of your suggestions .

I lived in a house built in 1840 and our local historic commission prefers original sashes topped by aluminum triple track storm and screen windows over those.

I restored my 1840 sashes and put this style of storm over top, while the owners of some other units replaced the old windows with modern windows, and 15 years later those newer windows are deteriorating and the 180 year old windows are still in great condition.

I have similar old windows in my LR, and luckily, I was also left with old storm windows that, although in terrible shape, fit perfectly. I took the old storm windows (for sizing) to a local glass & glazing place and asked them to make me screens and storms.

eta: to be clear, both my screens and my storms are installed from the outside. They are made with a thin metal frame, so that they can be installed on top of each other.

Thanks for your ideas about fabricating vs buying.  That's amazing that the old windows outlived the replacement ones.  

Another concern is maintenance.  What is the process going from hot to cold weather and vice versa? I've never lived in an old home, and have little to no real life experience.
