Exterior storm windows are mounted by their flanges to the fame. When caulked effectively, they seal the perimeter so that it is free of air leakage. Here are some details about the different parts that make up a residential exterior storm window.

Exterior windows typically work on a two or three track system. Two-track storm windows are available for protecting vertically moving windows and horizontally sliding windows with two sash. One setup available has a screen and sash in one track and a moveable sash in the other. A triple-track storm window has the screen and each sash in there own track. This allows the screen to be kept stored on the frame by sliding it up to the top of the frame and allows the top opening to be used for ventilation.

Exterior storm windows can also come in a fixed panel option. They do not permit ventilation and need to be removed occasionally for window maintenance. It is a good idea to take your fixed storm windows off once a year to allow your windows a chance to breath and clean the inside of each pane.

The frame and sash are made from aluminum for its strength and its also known to be maintenance free. The glazing may be a glass or acrylic material. The screen is typically made from an aluminum or plastic material. Aluminum screens are more sturdy but will dent and plastic will not dent but can bend more easily.

When choosing a window for energy efficiency, note that those made by an American Architectural Manufacturers Association (AAMA) manufacturer or certified by the National Fenestration Rating Council (NFRC) will have a performance rating for each type of window.

Exterior storm windows are usually produced by a local manufacturer who will measure your windows and make them to fit your openings. They provide allowances to overlap the window casing which allows the windows to be screwed in place.

These windows are relatively easy to install. Center the storm window over the prime window opening and install one screw in a predrilled hole at a top corner. Adjust the window so it is level and add a screw on the other corner. Starting from the top, screw along the sides of the windows working down and then screw in the bottom. It is important that the sides are not bowed inward – if this happens, your window will not slide.

After the screws are in place, lay a small bead of caulking along the edge of the aluminum frame where it touches the wood window casing. Adding these will often cause an increase in the humidity and temperature between it and the prime window. This can cause damage to your wood or vinyl frame so if you notice this you will want to make sure you release the storm window to allow air in and burn off the humidity. As the temperatures get warmer, there is a greater chance for this.
