Replacing old, inefficient windows with new ones can help you save on electricity bills, but you want to make sure that the benefits of replacing your windows outweigh the cost of the upgrade.
A post on Angie’s List describes three factors to consider when buying replacement windows to ensure energy savings that make your investment worthwhile. These include the following:
- Type of window – U values and ratings; frame material; installation method; and the difference between your old and new windows.
- Architectural and landscaping factors – size and number of windows; placement of windows; available shade around the house; and patios or overhangs covering the window glass.
- Utility habits and other factors – where you set your thermostat; age of your air conditioning unit; and the amount and type of insulation in your house.
The energy savings you reap from replacement windows is basically the difference between your old windows and your new windows. If there is much of a difference in their energy-efficiency qualities, then you can be assured of greater savings with your replacement windows.
