When people buy new windows, the primary concern is usually the visual appearance of the window on the exterior of the house. While it’s important that your new windows match your style’s decor, this is also a great opportunity to increase your home’s energy efficiency. Before scheduling an appointment with a contractor, take the time to find a window that not only looks great but can also help you save money on heating and cooling costs. Here are 3 ways you can achieve better energy efficiency with your new windows. 
Go With Multiple Panes of Glass
Some windows are designed with double or triple panes. These windows are built with greater energy efficiency in mind. The extra panes can help trap air as it tries to move into the house. Some window manufacturers also include special gases in between the panes such as argon, which provide even better insulation.
Pay Attention to the Energy Performance Ratings
Did you know that windows are officially rated on their energy efficiency and have a specific number attached to their rating, similar to how your car might have a specific number to help you determine its gas efficiency? Windows are rated on everything from “air leakage” to their solar heat gain, which is how much heat from the sun they retain. Talk with a professional to help you understand what these ratings mean in detail and then select a window that has great efficiency ratings to help keep your energy costs down.
Take A Look at the Frame as Well
Sometimes even if you have an energy efficient window, the frame or trim around the window could be causing problems for you. If it is time for new windows, think about whether you want a brand new installation, new trim included, instead of just putting replacement windows inside the old trim. Changing the type of material the frame is made out of can help in this situation. For example, vinyl trim typically provides better insulation than wood trim. Talk with a windows expert about what options might work best for you and your family.
If you have been thinking about getting replacement windows for your home, this may be an opportunity to take some money off of your annual energy costs. Windows are rated by how effective they are at energy efficiency in several different categories. It’s also possible to buy windows with multiple panes of glass to provide even better insulation. Finally, if you believe your window trim or frame is not providing proper insulation, talk with a professional about starting from scratch with brand new windows and trim as well.
