We have decided to restore by a contractor a few 2 over 2 old Colonial windows that are over 5' tall. I have read how the top sash when lowered let out the hot air and the bottom sash opened would let in the cool air. They have aluminum storm windows, 3 tracks with one screen. I'm thinking I need 4 tracks with double screens so bugs won't fly in when the top sash is opened. Were these not made in earlier times or am I dreaming?
We are planning to do one window this year and see how it comes out before we do the rest. Contractor gave us a price for a new Harvey storm window; doesn't come in the trim color we have and we would like to be able to use the existing storm to save money for now and see how it works. We could replace the storms next year.
Any advice on how to prevent bugs from flying in top sash if we keep the 3 track storm?
Also, I did not see a post on restoring aluminum storms for drafts...is there such a thing or not worth it?
FYI...current prices for mechanical and historical restoration $800 + and new storm approx. $250-$300 installed
