Old basement windows like the one in this home, often have wood or metal frames that rot or rust respectively. They are leaky and the single panel of glass makes them highly energy inefficient. We replaced it with our EverLast Basement Window. It has a vinyl frame and is made with double-paned, low-E glass. It will keep out hot air in the summer and cold air in the winter, and the frames will never rot, rust, decay, or need paint.
