We are considering replacing most of the windows in our house. They are about 40 years old and orignal to the house. I'm not exactly sure what type of windows they are but we turn a crank to open them. They do not seal very well and when we walk by, we can feel the air blowing through. They do have weatherstripping, but it doesn't seem to be doing the trick. They are very attractive,(three or four large panes of glass depending on the size of the window) but are not energy efficient. We have about 13 windows to deal with and they vary in size (roughly 52" X 50", 36" X 36", and 53" X 38"). Are there any projects we can do to these windows to extend their lives? We live in southern Mississippi and the climate is relatively mild in the winter, but summers are hot, hot, hot!

I am trying to replace the failing crank-open hardware on my 15 year old wood frame windows. It seems like in order to find the right hardware, I need to know the manufacturer of the windows. There is nothing stamped on any of the windows to reveal the manufacturer name. How/Where do I find what I am looking for?
