    Types of Windows

    Vinyl
    A unique combination of versatility and durability, vinyl windows have become a favorite among homeowners nation wide. They are available in a wide range of styles and shapes, are easily customized, are competitively priced, require low maintenance, and mold easily into almost any shape. Also can be painted over, however the paint won't look as good as it does on a Wood Window.

    Wood
    Wood is probably the most visually appealing replacement window. They come in many different shades and sizes. Wood is a very good insulator. Wood windows battle extreme temperatures well and won't usually be affected. Wood is however, susceptible to shrinking and swelling, and requires more maintenance than vinyl. If regular maintenance is not done, wood frames may warp or crack.

    Aluminum
    One plus for Aluminum is the strength of the material. Aluminum is the strongest of all the windows. Also aluminum doesn't deteriorate or shrink, swell, crack, rust. It's weakness is it's ability to conduct heat, it may allow heat, cold and moisture to creep in from the outside.

    Window Panes

    Double-pane
