Heat mirror is a type of energy-efficient window technology that uses a special film to selectively reflect certain wavelengths of light while allowing others to pass through. It works by reflecting infrared radiation (heat) back into a room during the winter months, while blocking it from entering during the summer months.

 

Heat mirror windows typically consist of two or more glass panes separated by a narrow gap. The heat mirror film is applied to one of the interior surfaces of the glass panes. The film is designed to reflect heat back into the room, while allowing visible light to pass through. This helps to reduce energy costs by reducing the amount of heat that is lost through the windows during the winter, and by reducing the amount of heat that enters the building during the summer.

 

Heat mirror technology can be used in both residential and commercial buildings, and is particularly useful in climates with extreme temperatures. It can also be used in combination with other energy-efficient window technologies, such as low-e coatings and gas fills, to further improve energy efficiency.
