Choosing Storm and Utility Windows

 
 

Storm windows are an economical, easy way to increase the efficiency of older, single-pane windows. They reduce the flow of outside air into your home. And, the airspace between the storm window and your existing window works as an added insulation factor.

Utility windows are a low-cost alternative to using regular house windows in areas that do not necessarily require them. Lowe's is happy to provide this information as a service to you.

Storm Windows

Storm windows are normally used in conjunction with single-hung, double-hung and slider-type windows:

  • Configuration options

    You may choose from two track, triple track, two track slider or basement (also called picture) storm windows:
    Two-track window. Two-track detail.
    Two-track
    Triple-track window. Triple-track detail.
    Triple-track
    Two-track slider.

    Picture window.

    • In a two-track storm window the half-screen and the outer pane or sash both rest in the outside track, and neither one slides up or down. The inside pane rests in a separate track and may be raised to allow fresh air into your home.

    • In a triple-track storm window each pane and the half-screen rests in its own individual track, so each sash can move independently. With this added flexibility you can pass items through the open window when necessary. You can also move both glass panes to the bottom of the window with the screen at the top for better cross-ventilation during temperate weather.

    • Two-track slider storm windows are just like regular two-track storm windows, except they open horizontally instead of vertically. Two-track sliders are usually used with slider windows.

    • In a picture storm window there is only one pane, similar to a typical picture window. The pane is held in place by thumb latches on the outside of the storm window frame for easy removal during mild weather. Some picture storm windows have a screen made into the inside of the frame to keep insects out when the pane is removed. Picture storm windows are usually only available in the following sizes:

Picture storm window sizes
Width Height
32 1/16" 14 1/16"
32 1/16" 18 1/16"
32 1/16" 22 1/16"

  • Color Options

    Storm windows are commonly available in brown, white and mill, a silvery, aluminum color. Some manufacturers also produce storm windows in almond. Most homeowners should be able to find a color to complement their home.

  • Measurement detail.

    Measure carefully for a good fit.
    Measuring for Storm Windows

    To ensure a good fit, it is important to have accurate measurements for every window in your home. Even though some windows may appear to be the same, it is best to measure each one individually.

    • To find the width, measure from the inside of the brick molding on one side of the window to the inside of the brick molding on the other side of the window. Measure at the bottom, middle and top of the window. Use the narrowest measurement for the width of your storm window.

    • To find the height, measure from the sill to the inside of the brick molding at the top of the window. Measure at the left, middle and right of the window. Use the shortest measurement for the height of your storm window.

    Using the smallest measurements ensures that the storm window's flanges will fit inside the exterior trim.
