Changing out the the type of window can change the aesthetic and look of the whole home.
Today, there are a number of high efficiency glass options on the market designed to reduce heat transfer into the home and UV radiation that can fade carpets, furniture, and other items in the home. On a cold day, low-E glass can also prevent the radiant interior heat from escaping through the glass, reducing your home heating bills.
Installing ENERGY STAR qualified windows lowers energy bills and saves you money over single-pane and even new double-paned, clear-glass windows. For a typical home, choose ENERGY STAR and save: $126–$465 a year when replacing single-pane windows. $27–$111 a year over double-pane, clear glass replacement windows.
