Katy Energy Efficient Windows

Everything is bigger in Texas—including the cooling bills! If you’re looking for ways to keep those bills in check during the hottest summer days, installing energy efficient windows in your Katy home is a great option.

The Window Authority of Houston has helped thousands of homeowners swap out drafty windows for high-performance products that will help reduce their carbon footprint, as well as their utility costs. Our family-owned business offers top-rated windows at factory-direct prices, so our customers enjoy the perfect mix of quality and value.

High-Performance Katy Replacement Windows

Not all replacement windows are the same, but many homeowners aren’t sure what to look for in a quality window. That’s where our knowledgeable window specialists come in. They will take the time to explain the features on all of the windows we offer, so that you can make an informed decision about which is best for you.

Our energy efficient windows boast many impressive features, including:

  • Quality Insulation
  • Double-Pane or Triple-Pane Glass
  • Gas-Filled Panes
  • Low-E Glass
  • Dual or Triple Glazing
  • Insulating Spacers

The savings are significant—if you’re updating from single-pane windows, you can save nearly $500 a year!
