Installing Aluminum Storm Windows

I recently purchased a 104 year old home that has double track aluminum frame storm windows, all of which have been removed and stored in the basement, along with their screens. None are labeled as to which window they came from and I am betting there are at least 50 down there. I have found a few pairs that seem to fit some of the windows, but don't have a clue as to how to install them. Do they install from inside or outside the house? They have little tabs on the side that seem to correspond with slots in the track, but I honestly can't figure out how to put them in. Since the windows themselves are loose and drafty, it's essential that I install them. Nope, I do not have anyone to help me and don't know of any trustworthy handymen in the area that I may call. Any insight would be very much appreciated! Thanks!

 

You have triple track storm windows. On each storm window and screen there should be four tabs, one on each side of a cornor. The two that are stationary is the top of the window. The bottom should have two tabs that slide inward. In order for you to install the storm windows (SW) the first SW must be slightly narrower than the second SW. Therefore for each SW there are two separate size SW. If both are the same size, one SW will either too wide to fit in opening or too narrow to fit in opening. The way to install is to open the window from inside the home.

Take the narrower of the two SW. The tabs that slide inward must be facing you.

Take the SW with the stationary tabs to the outer most track and tilt tabs to fit in the tracks and slide the SW up until the tabs the slide inward meet the tracks. Then slide in the tabs so the SW fits in tracks and release tabs.

Do the same thin with the narrower SW and you're done.

The screens are the last to be installed.

This is not as hard as it sounds. After you do a couple, you'll be a pro.
