How Installing Energy-Efficient Windows in Prospect Saves You Money

There are quite a few benefits of switching to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Prospect, that’s about 147 pounds per year on average.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
  • Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of residential energy use. Switching to energy-efficient windows can help lower that amount, which helps you save more on your bills.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
