Storm doors are installed outside of exterior doors protect them from the elements and create an insulating air space between the doors. Storm doors are designed to be entirely removed and stored, although others have screens which can be interchanged with glass or acrylic panels for use during warmer weather. Self-storing models allow the glass/acrylic panels to slide into another position on the door without needing to be removed.

A large range of materials and options affect the price and quality of storm doors. Full view panels allow the exterior door to be seen. Kick plates protect the lower portion of the storm door. Vents on the top or bottom of the door allow circulation. Security features such as grids and dead bolt locks add an extra barrier of protection.

The most popular colors are natural mill aluminum, bronze and white but many manufacturers offer a wider assortment of colors including black, hunter green, almond, brown, cranberry and even indigo.

Other Types of Storm Protection
In certain climates, storm doors will not be enough protection from the violence of some storms. Storm shutters, storm windows, and storm shelters offer great protection against extreme weather. Also, garage braces are a relatively new trend that help to fortify a typically flimsy garage door into something solid.
