I want to replace some old windows with something more insulated, double pane or such, on a cabin in the woods we use in the summer. I don't know what this type of window is called or what to look for a similar style that opens fully to get maximum airflow through the house from the window opening size. I'd rather not go double hung or similar and get half the airflow of the old windows, but it would be nice to have more insulation for the colder months. They open the glass about 45*. Doesn't have to be the same exact style, just something that will use most of the window opening size to allow air to flow and a more modern double pane to stay warm in winter.
Picture of open windows is only on one side of the house, probably go larger double hung there to take the whole height but the other three walls have just the small lower windows that open. Rough opening is for the small windows, no glass above on the other sides. I'm more of a car guy than a house guy, trying to figure out what I should be looking for or asking for to order custom sizes.
