The double-hung window is especially suited to a traditional-style home with exterior shutters.While these windows are traditional in style, modern materials and assembly techniques make them much better than their wooden ancestors. Exterior cladding now includes vinyl, fiberglass, composite materials and aluminum. Interior ones come in just about any species of wood, and the hardware (such as thumb locks and sash lifts) can be in whatever finish you'd like. And there are a variety of glass options, from single to double to triple glazing as well as coatings and films that can be applied.While you can get a double-hung window for as low as a few hundred dollars, depending on its size, a better window that is excellent at saving energy and has a low-maintenance exterior finish will cost considerably more.
