How do Low E glass windows work?
Sunlight delivers visible light, ultraviolet or UV light and infrared or IR light. Ultraviolet light can damage skin and also cause fabric colors to fade. Infrared light is heat. Low E glass allows the visible light to pass through while blocking some of the UV light and IR light. The powerful infrared light in sunlight actually heats up objects such as floors and furniture inside and sidewalks and patio furniture outside. As objects cool they emit a low powered form of infrared lights. Low E glass can reflect this form of energy. In summer this keeps your house cooler as the warmer outside heat is kept outside. In winter, heat from objects that are heated by sunlight or other inside sources is bounced back into your home to keep your home warmer. With Low E glass, cooler indoor temperatures in the summer and warmer indoor temperatures in winter can reduce energy use and lower energy bills. There are different types of Low E glass. Most Low E glass is divided into two types, hard coat
