The Economics of Energy-Efficient Windows

Most people don’t understand how much money is leaking out their windows each month in the form of wasted energy. This is especially true for windows that are more than 10 years old.

And, of course, wasted energy means higher energy bills. Remember:

  • As energy costs rise, there are few things as valuable as energy-efficient products on your home. Although energy costs fluctuate, they continuously go up over time, and that trend is expected to continue for the foreseeable future.
  • With uncertainty about climate change, heating and cooling needs could very well increase significantly, making it even more important to outfit your home with energy-saving replacement windows. Good windows don’t just keep you warmer in the winter; they also help keep your home cooler in the summer by reducing heat transfer.

The bottom line is homeowners need to protect themselves as much as possible from energy price increases. Investing in new technology and new products, such as energy-efficient windows, for your O’Fallon, MO home is one of the best ways to accomplish this.
