how can homes be energy efficient through windows

Windows can be energy efficient by utilizing design elements and special materials with specific properties that can keep conditioned air in, or keep warm air out, depending on the season. Low-emissivity (Low-E) glass is a great option for energy efficiency as it uses an invisible coating that reflects radiant heat from the outdoors and absorbs solar energy from the indoors, making it great for harsh climates in both very cold and very hot environments. This treated glass can also be coupled with argon gas fills, whicacn further increase the efficiency. Additional design elements, such as insulated frames, improved seals and weather stripping, and multi-paned glass can also significantly increase the efficiency of your windows.

heat is often lost through windows. double-glazing, heavy curtains and shutters can help reduce this loss
