GETTING TO KNOW CASEMENT WINDOWS – PART 2: CASEMENT WINDOWS AND ENERGY EFFICIENCY

Getting a good window replacement is no longer just about what looks better in your home or which one provides the best view. Today, one of the things that separate average windows from the excellent ones is energy efficiency. There are different ways by which a window can contribute to improving your home’s energy efficiency and this is how a casement window does it.

Cooling Down

One of the main functions of a casement window is to provide ventilation, which it does better than other window types. Having a quick way to air out your home not only makes it faster to cool down during a hot summer day, but also makes it easier for your air conditioning unit to regulate indoor temperatures once the window is closed.

Warming Up

Just as your air conditioning unit uses power to cool down your how, your heater also uses up a lot of energy trying to keep you warm during the colder seasons. However, cold air coming from outside can disrupt heating inside the home, pushing your heating system to work doubly hard to keep you warm. Energy-efficient casement windows take care of this problem by keeping indoor heat in, allowing temperature inside your home to stabilize.

Natural Lighting

Daylighting refers to the use of natural light to illuminate. With a large glass area, a casement window supports daylighting efforts by letting in a lot of natural light. This lets you reduce your dependence on artificial lighting as you can harness natural light during the day. It might not seem like much but a few hours of not turning on the lights in your home everyday will add up, the results of which you’ll see on your energy bill down the line.

Energy Efficiency vs Energy Conservation

Energy efficiency and energy conservation are commonly used interchangeably but they are not the same thing. To put it simply, energy efficiency refers to wiser use of energy while energy conservation pertains to using less energy. However, energy efficiency can lead to energy conservation and vice versa.

"Have nothing but great things to say about the window installation done today by John Hutchinson with Renewal by Andersen! He was friendly, personable and professional and did a great job installing. He did a great job of putting down roller pads and tarps with next to zero clean up. Would highly recommend them for any window replacement needed!"

"We had our new Renewal by Andersen windows installed on June 5th & 6th, 2025 and we LOVE them! The quality, beauty, and functionality are best-in-class! The whole experience from dinner presentation at Lazy River Grill, the initial in-home sales consultation and measurement, the regular communications from the salesman and concierge, and the installation team’s professionalism and skills made the process so seamless. This is the second home we have opted for Renewal windows and doors and have been delighted both times! Thank you Renewal by Andersen STL! "

"I had an excellent experience with RbA STL. Our designer, Courtney, was great and the finished product is awesome. The installation was easy and the gentlemen left our home cleaner than they found it upon entering. I would recommend RbA STL - you’ll get tired from their constant contacts, and that’s a GOOD thing!"
