Vinyl windows are the least expensive and most popular type of replacement window.
Wood windows have a wooden frame and sash. They are wood throughout and can work with any home.
Wood-clad windows consist of a wooden frame and sash with a thin layer of aluminum, fiberglass, or vinyl wrapped around the exterior frame.
Since aluminum is strong, low maintenance, and malleable, it’s a good pick for homeowners wanting a modern look.
Fiberglass windows are the most energy efficient and strong of all materials, but these frames are not as widely available.
