Replacement Windows VS New Construction Windows

4 minute read


If the time has come to replace your windows, you may be understandably overwhelmed by the variety of available choices, and the unfamiliar terminology used in the window business confuses the issue further for many people. For instance, you may be struggling with the decision between replacement windows and new construction windows. Here’s what you need to know to make an informed choice on this subject.

What Are Replacement Windows?

The first step in understanding what replacement windows actually are is getting a firm handle on the industry terminology. Replacement windows are also referred to as retrofit windows or insert replacement windows. Replacement windows are typically installed into pre-existing homes and are designed so that it is not necessary to remove the exterior material surrounding the windows in order for them to be installed. There are two main types of replacement windows: block frame and flush fin.

  • Block frame windows are used when the original window frame is solid and intact, leaving only the sash to be replaced before the window is installed. This procedure is usually performed on existing homes that feature exterior siding made from brick or siding.
  • Flush fin windows, otherwise known as Z-bars, are used for windows featuring aluminum construction. They’re used on homes with stucco or masonry exteriors and have a flange designed to provide added stability to the window as well as conceal its existing frame.

The Advantages of Choosing a Replacement Window vs New Construction

Because having replacement windows installed does not entail the removal of exterior materials and the entire replacement of the frame, it’s a much faster option than choosing new construction windows. Installation costs are typically much lower as well, making it an ideal choice for homeowners seeking a quick weekend upgrade. Installation of replacement windows also involves minimal household disruption since the process is relatively quick and doesn’t involve removing and replacing any of the existing construction, so you and your family won’t have to worry about loss of peace and quiet in your home — it takes an average of one day for two people to install between 10-15 of these windows as opposed to five days for the installation of the same amount of new construction windows.

When to Choose Replacement Windows

Replacement windows offer homeowners an excellent choice for existing homes with intact window frames. They are also good options if you’re on a tight budget or need to get the job done as quickly as possible.

What Are New Construction Windows?

New construction windows are primarily used when you’ve built an addition to your home or in brand new construction. The installation of new construction windows involves the removal of exterior materials so that the contractor can access the studs. The window is then installed on the studs and the exterior material is replaced.

However, some homeowners opt for new construction windows over replacement windows in an existing home for a couple of different reasons.

When to Choose New Construction Windows

If the window frame or studs have experienced extensive damage, for instance, it makes little sense to have a replacement window installed. Also, if you’ve got a particular window shape or size in mind that’s a bit unusual, new construction windows are the way to go. it’s also a good option if you are replacing the exterior siding of your home.

We live in Roy in a double wide trailer. The installers Eli and Josh did a fantastic job and made our home look NEW. These young men took the time to to make each window look wonderful - both outside and inside. They did not want to take time for lunch so we fed them pizza. Wonderful, wonderful product and investment. Kudos to ELI and JOSH for their positive attitude and professionalism!!! Definitely will call Advanced Windows for our next project!!!! - 10/07/2026

We had all of the windows replaced in an older apartment complex (over 100 windows). They did such an amazing job!!! The guys who installed the windows were so knowledgeable and worked so fast. It looks amazing!!! We replaced 50 - 60 year old windows and our tenants are already noticing the difference - it stays cooler in the apartment, less bugs, less noise. Thanks to everyone!!! - 10/06/2026

We just had Advanced Window Products install our windows for our whole house. We heard the interview that Joe had on the Garret Lewis show on 550am. And from the beginning all the way to the final window installed they were respectful and professional. The installers were Roger,Victor,Raul and Angel. They were kind and respectful and did great job. We absolutely recommend this company to anyone that needs windows. My wife and I love the way our house looks.Thank you God blessJose and Penny - 10/01/2026

We had a fantastic experience with Advanced Windows. The installation team was professional, friendly, and incredibly efficient. They took great care of our home and actually left the areas cleaner than when they arrived! We had a small issue with one of the windows, but they addressed and fixed it right away without any hassle. The windows themselves are beautiful and high quality. We are already noticing our home stays much cooler on hot days. Highly recommend! - 10/01/2026
