Pronunciation: [stˈɔːmwɪndˌə͡ʊ] (IPA) 
The word "stormwindow" is spelled phonetically as /stɔːmˈwɪndəʊ/. The first syllable "storm" is pronounced with a long "o" sound followed by the letter "r". The second syllable "window" is pronounced with a short "i" sound followed by the letter "n", then a long "o" sound, and ending with the letters "w" and "dow". This word is used to describe a window designed to protect a building from strong winds and rain during a storm.
A storm window refers to an additional window panel that is installed on the exterior or interior of an existing window. It functions as a secondary barrier that offers protection and enhances insulation against adverse weather conditions, such as storms, high winds, rain, snow, and extreme temperatures.
Typically made of glass or acrylic, storm windows are designed to provide an extra layer of insulation by creating an air pocket between the existing window and the storm window. This trapped air space acts as a buffer, reducing heat loss during colder months and heat gain in warmer seasons. Storm windows are often used as an energy-saving solution, improving the overall efficiency of a building's windows and reducing heating and cooling costs.
Aside from their insulating properties, storm windows also offer protection against damage from flying debris, hail, and heavy rain during storms. They add an extra layer of security against break-ins and can help reduce noise transmission from outside, making the indoor environment more peaceful.
Storm windows come in various styles, such as fixed, hinged, or removable panels, allowing for flexibility in installation and maintenance. They can be customized to fit different window sizes and frames. Some storm window designs include screens to allow for ventilation when desired.
Overall, storm windows provide an additional layer of insulation, protection, and energy efficiency to an existing window, prolonging its lifespan while enhancing comfort and safety within a building.
The word "stormwindow" is composed of two parts: "storm" and "window".
The term "storm" dates back to Old English (circa 900s) with the word "storm" meaning "a violent disturbance of the atmosphere". It is derived from the Old Norse word "stormr", which has the same meaning. Old English "storm" evolved into Modern English with the same spelling and meaning.
The word "window" originated from the Old Norse word "vindauga" (literally "wind's eye"), which was adopted into Old English as "vindauge". Over time, "vindauge" was shortened to "window" but retained the meaning of an opening in a wall through which light and air enter.
Therefore, "stormwindow" refers to a type of window designed to withstand harsh weather conditions such as storms.
