There are several synonyms for the word screen door, including storm door, fly screen, and security screen. The term storm door refers to a removable glass or screen panel that protects an exterior door from harsh weather conditions such as rain, wind, snow, and hail. A fly screen, on the other hand, is a mesh screen that keeps insects and bugs out of homes while allowing natural airflow to enter. Lastly, a security screen is a heavy-duty mesh screen that offers extra protection against burglars and intruders. Regardless of the term used, screen doors are an essential part of any home that provides ventilation and protection.
