Thought I'd bump this thread. Yesterday the workers came and installed two new windows in my living space/bedroom. Much better windows, double pane and sash type. My other windows that these replaced were almost sixty years old and one windows pane was broken. They were called awning windows and very difficult to keep heat in and to photograph through. These new one are easy to shoot through as I can raise the bottom half and have full view of my feeders/birdbath and the trees, the birds and squirrels frequent.
