We'd like to seal our house a bit tighter. Some of our windows seem to lose a fair amount of heat. We've just painted our window sills, so don't want to use shrink-wrap plastic. A few of these windows are Anderson windows, and I wondered if there are any storm window replacements that slide in place of screens. The screens wedge in at the top, and have pressure clamps that hold them in on the sides. It seems like it should be possible to design similar storm windows that could go in during the winter. But I haven't seen anything like that. Is this a silly idea? Would storms not even be worth the trouble on reasonably well installed modern 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!
