I am looking for what I call a "garden window" for my new construction. I already have a rough opening of 2' 1/2" wide by 3' 1/2" high. The window cannot extend more than 1' beyond the building wall. Is there a ready made window such as this or can you tell me how to make one and can you supply me with the thermal pane windows?
Garden windows don't hold up too well in the long term. They get very cold in the winter and hot in the summer because the air from the house doesn't circulate in the space that protrudes from the home.
