What method is effective in reducing energy loss through windows?

Installing storm windows is an effective method for reducing energy loss through windows because they provide an additional layer of insulation. Storm windows create an air gap between themselves and the primary window, which acts as an insulating barrier. This air gap reduces heat transfer, helping to keep indoor temperatures stable during both hot and cold weather.

Storm windows are particularly beneficial in climates with extreme weather, as they can significantly minimize drafts and improve energy efficiency in homes. Additionally, they can help protect the primary windows from the elements, prolonging their lifespan.

In contrast, using single-pane windows tends to lead to higher energy loss since they provide minimal insulation. Leaving windows open during storms can allow moisture and cold air into the home, which is counterproductive to energy conservation. Also, not using curtains or shades can result in heat loss at night or during colder months, as these coverings can help retain indoor warmth when closed.
