Window Styles: A Simple Guide

When it comes to choosing replacement windows, several factors must be taken into consideration. Frame materials, glazing options and energy efficiency are all important, but the window style is something you should prioritize from the start.

Bay window

Double-Hung Windows

Clean and simple, these operable windows are arguably the most recognizable window styles available today. With two sashes that slide vertically, they allow access to better air circulation around your home. If you are looking to boost your home’s energy efficiency, these are the windows to consider.

Casement Windows

This particular window style is the go-to option for many homeowners until sashed windows became popular. They have single or double panels that are hinged on the side, which means they open outward. These are a great choice if you want to increase natural ventilation and bring more natural light into your home.

Sliding Windows

Thanks to the windows’ sleek frames and wide glass area, they fit well in modern and contemporary homes. Sliding windows also allow you to maximize the space inside your home.

Picture Windows

Despite being fixed and inoperable, picture windows help maximize your home’s outdoor view. They also provide an airtight and durable seal to ensure consistent indoor comfort while keeping your monthly utility bills from spiking. They can even serve as accents for other windows and even French doors.

Bay and Bow Windows

If the focus of your window replacement is on aesthetics, bay and bow windows are the way to go. The former features a main window flanked by two others on both sides at an angle while the latter is made up of at least four panes that form a gentle arc. These windows bring in natural light, opening up your space and making it more spacious.

Reviews

"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!"
