One of the things you’re going to notice when you’re researching replacement windows is the number of choices you have. What sort of frame construction – vinyl, aluminum, wood, fiberglass?  What manufacturer – Simonton, Milgard, Marvin? They each have their benefits. What if you want to change a window style, like make that big back window into a sliding door? Do you make it a regular slider or a French door slider?  What’s the difference?
