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.

My wife and I were very satisfied with Advanced Window Products. Replacing eight 60-year-old single-pane aluminum windows was a smooth process, from the accurate descriptions and color selection to the precise measurements.As promised, the windows were ready two months after we placed our order. The installers were very careful when removing the old windows from the brick walls and installing the new custom double-pane windows. They completed the entire project in just five hours, and the windows look great. - 6/11/2026

I recently had all my windows replaced and had a great experience with Advanced. That sales process was quick and respectful without having to sit through a long drawn out sales pitch. They were efficient with their time at our home and they will dows are great. We have noisy neighbors and with the new windows we dont hear their late night music which is such an added bonus. Our home temperature also has stayed consistent with a decent reduction in our cooling costs. - 6/10/2026

We recently installed 13 new Advanced Windows and have already noticed a difference in the heat efficiency of the windows. The installation team was right on time and finished in less than a day! We have received many compliments on the looks of the windows. They were easy to work with through the whole process of purchase, communicating timelines, scheduling and installation. The windows are a great product and at a good price. I recommend working this Utah company. - 6/08/2026

Crystal Nielson-Barney went out of her way to help us. They made beautiful windows in time for us to sell our house, and when we accidentally broke a pane in the new window, Crystal made sure we had the replacement in just over a week so that we could close on selling our house. We highly recommend Advanced Windows and their professional team. - 6/05/2026

We recently had our windows replaced by Advanced Window Products, and we couldn't be happier with the results. From the initial consultation with Joe to the final installation, the entire process was smooth, professional, and stress-free.A special thank you to Miguel and Rogelio, who did an outstanding job with the installation. They were punctual, courteous, highly skilled, and paid close attention to detail throughout the project. Their craftsmanship and professionalism were evident every step of the way.The new windows look fantastic, and we've already noticed improved comfort and energy efficiency in our home. The work area was kept clean throughout the installation, and everything was completed in a timely manner.We also appreciated that Advanced Window Products proactively coordinated the removal and reinstallation of one of our interior shutters to ensure the project was completed properly and without inconvenience to us.We highly recommend Advanced Window Products to anyone looking for high-quality window replacement and exceptional customer service. Our experience exceeded expectations, and we are extremely pleased with the outcome. - 6/02/2026
