Customers Question about Indented Window

A customer called in and asked advice on what type of window to use if the existing window is not flush with the wall. Some windows are indented in a couple of inches deep. I didn't know the answer so I asked one of our installers here. They recommended purchasing dual wall flush fin windows, and then cutting the flush fin down so it will fit into the opening. I decided to write a short article in the Do-It-Yourself section in case there are other people with the same question: http://discountdw.com/p-6858-replace-a-window-that-is-indented-or-not-flush-with-the-wall.html
