The low-e (low emissivity) coating on windows primarily serves to reduce heat loss. This special microscopic coating reflects infrared energy, which helps keep heat inside during colder months and reduces heat gain in warmer months. By doing so, it enhances the energy efficiency of the building, leading to lower heating and cooling costs.

This coating works by allowing visible light to pass through while controlling the amount of infrared and ultraviolet light that is transmitted. By minimizing heat transfer, low-e windows help maintain a comfortable indoor temperature regardless of the weather outside, making them a valuable element in energy-efficient home designs.

Other aspects of window coatings, such as aesthetics or structural integrity, aren’t the main focus of low-e technology. Protecting against UV rays is certainly an added benefit of low-e coatings, but the primary purpose remains centered on the control of heat loss and gain.
