This debate regarding replacement windows vs. new construction isn’t just limited to home renovations, though. It’s applicable to a wide range of home improvement upgrades. In this article, we will take a closer look at the replacement windows vs. new construction debate.

I. Introduction

The window that you choose to install on your property can have crucial, long-lasting impacts on a number of different factors. These range from overall energy costs to your comfort level, window’s durability, and more.

From the different material options you have to choose which is better; replacement windows vs. new construction, there are a number of considerations to make. Let’s take a closer look at the options you have, what each decision will lead you to, and the key aspects that you will have to consider.

II. Replacement Windows

With replacement windows, you are essentially getting a new window that fits into the existing opening in your wall. These are suitable for property owners who want to upgrade their window, without making too many changes in the existing structure.

1. What Are Replacement Windows?

These are custom-made windows that replace your old windows, without any alterations to the existing frame. In the replacement windows vs new construction debate, these are usually more cost-effective and easier to install.

Remember, though. While replacement windows must fit into the same frame, they do not need to be the same design. If you are looking for an upgrade, you can also change the style. However, the existing frame will limit your options quite a bit.

For instance, you can easily install a sliding window into a frame of casement or awning window. You only need to make sure that it is the same size as your existing window.

2. Use-Case/When to Use Replacement Windows?

Let’s say your window is damaged due to poor construction, natural disaster, or because of age. But if the frame is in good condition, replacement windows are your best option. These windows are usually suited for property renovations where you want to achieve a specific goal without major reconstruction. Your goal may be to:

You should look for NFRC and ENERGY STAR certifications to ensure you get the best possible performance and energy savings from your windows. The NFRC (National Fenestration Rating Council) certification measures several factors to determine the efficiency of windows, doors, and skylights. These include:

On the other hand, ENERGY STAR certification is an EPA-backed program that provides strict energy efficiency guidelines for different products. Its goal is to help you save money on energy bills and reduce emissions.

3. Common Challenges in Replacement Window Projects

When considering replacement windows vs new construction, there is no doubt that replacement window projects are much more convenient. However, they present their own set of challenges, too.

One of the biggest challenges stems from structural issues. The frame of your window is most likely going to be exposed to a wide range of elements. From the sun’s UV rays to rain, snow, dust, foliage, and more. So, your property will settle over time and affect the frame itself.

Rotting and warping of frames is the most common issue there. To deal with this, you may need to repair or reinforce the existing frame before installing the new one. The second challenge arises here: accurate measurement. While repairing, you may find that the replacement window may not fit properly.

Windows need to fit precisely into their frame. Even the slightest gap can result in air leakage or provide an entry point for insects and critters to enter your property. Apart from the energy efficiency issues, it also presents a hygiene issue over time.

And this is directly connected to the third issue: weatherproofing. Replacement windows usually rely on precision of their fit. The installation quality is also a direct determinant of how weatherproof a window really is.

For example, if your home has a stucco exterior, you may need a flush fin replacement window. While aesthetically, these are very pleasing, they settle within the existing frame, and the fin will cover it up. However, installing a flush fin replacement window can be quite challenging, especially when the old frame isn’t in good condition.

III. New Construction

You will find new construction windows in new buildings more commonly. However, they are also used quite extensively in major renovations projects. Since these require reframing the wall, they are common in renovations where the contractor strips the wall to its studs.

1. What Are New Construction Windows?

When comparing replacement windows vs new construction windows, the most distinct difference is the nailing fin. New construction windows come with the mainlining fin, which you will attach directly to your house’s frame. Thanks to the nailing fin, these provide a much more secure and permanent fit.

You should note that while replacement windows are custom made to fit existing frames, you will need to make the frame specifically for new construction windows. You will need to cut out the frame based on the exact measurements of the nailing fin.

2. Use-Case/When to Use New Construction Windows?

As mentioned, new construction windows are the best for new homes. To install them, the installer will need access to your property’s framework. This is why if you need to install a new construction window during renovation, you will need to expose the studs and the sheathing for these windows.

The nail fin that comes with new construction windows attaches directly to the framework. The walls then cover the fin and sit securely around the window frame. Therefore, this leads to a weather-tight seal and a snug fit from the very beginning.

New construction windows are commonly used in the following cases:

3. Factors to Consider in New Construction Windows

In most cases, installing a new construction window is relatively straightforward. However, there are some considerations to keep in mind to ensure longevity with your project:
