How To Identify Andersen Windows

Livingroom Windows

Many homes are equipped with Andersen products, especially Andersen windows, but it is important to identify the product to find the proper replacement when replacing them. If it is time to replace your Andersen windows, you may be wondering how to identify older Andersen windows.

Older Andersen windows can be identified by the product label or the etched logo. You can find product labels at the top of the window frame or underneath the interior trim stop. Etched logos are located in the corner of the glass. You can identify the window by product number and date of manufacture.

Andersen windows are of exceptional quality, and when it comes time to replace them, it is important to find the appropriate Andersen replacement to ensure the same high quality. Identifying older windows can be tricky if you are replacing older windows, but there are a few ways to identify Andersen windows accurately. Let’s discover how to identify older Andersen windows correctly

Do Andersen Windows Have Identifying Features?

Anderson is a company that has been producing high-quality windows and doors for many years and has become a trusted brand in the industry, but identifying them can be a challenge. Do Andersen windows have identifying features?

Windows that Andersen produces can be recognized by their quality but also by their shape. Andersen produces a range of unique window designs that other manufacturers do not produce. Andersen windows have defining logos and etching as well.

The windows that Andersen produces are designed to last, and they can be used for a long time without requiring a replacement.

However, windows are not permanent, and they do not last forever. At some point, a window will need to be replaced. Whether the window has been broken or simply too old to keep installed, replacing a window requires first identifying the window type.

Fortunately, Andersen windows have a few defining features that set them apart from other brands. The first step in identifying an older Andersen window to replace it to identify these defining features.

Among the most obvious defining features of Andersen windows is the build quality. If the older windows on your house are designed and built very well and have minimal weathering despite their age, they are likely to be Andersen windows.

The way a window is designed is also a defining feature that can illude to a manufacturer, and Andersen windows are no different.

Andersen windows are made in four distinct designs, including double-hung windows, awning windows, gliding windows, and casement windows. Andersen also produces various specialty windows.

These designs are specific to Andersen windows, and they each have distinctive features that set them apart as Andersen products.

Another defining and identifying feature that all Andersen windows bear, regardless of age, is an etched Andersen logo on the glass.

How To Identify Older Andersen Windows

Older Andersen windows bear the same defining features as modern Andersen windows, which means that identifying them is relatively simple.

To identify older Andersen windows, locate the etched logo on the glass. This logo will indicate the product type with a product code, and it will indicate the year or exact date that the window was manufactured. Since 2007, all Andersen windows have product labels with identification information.

The most accurate and easiest way to identify an Andersen window is to locate and interpret the etched Andersen logo on the window glass or locate the Andersen product label that is often cleverly hidden on the window.

Let’s look at each of these identifying labels more closely:

Andersen Window Etchings

Andersen windows that were manufactured before 2007 may not have a product identification label. Still, all Andersen windows have an etched logo on the glass that can help identify the window, regardless of when the window was manufactured.

Andersen Etching

Pre-2007 Andersen windows have an etched Andersen logo in the corner of the glass. This etching also displays a set of figures below and to the right side of the Andersen logo.

The figures on the right side may read something similar to “CIG 3.8 1 – 06”. The last digits in the marking (1 – 06) indicate that the window bearing this marking was produced in the first quarter of 2006.

The figures below the Andersen logo are a product code that identifies the type of glass used in the window.

Andersen windows that were produced after 2006 have both a product label and an etched identification logo. The etched logo that has been used since 2007 bears more information than the older etched logo.

The key feature of these more recent etched logos is that they bear the same product identification as the product identification label, includes the exact date of manufacture, the type of glass used in the window, and the product identification number.

These figures can be used to identify the window by using the Andersen online product identification worksheet. Input the identification figures from the logo into the worksheet, and the online database will help you decode the relevant information.

Andersen Window Product Label

The product label provided with all Andersen windows since 2007 is the best way to identify the exact product.

These labels are usually located somewhere on the window frame itself and usually go unnoticed.

Check the window carefully to find the rectangular product label sticker. It is usually located at the top edge or the bottom of the inside window frame, or it may be hidden under a part of the interior trim.

The label may only be visible if the window is opened, as some of the frames may obstruct the label from view when the window is closed.

Once the label has been located, it can be used to identify the window easily. These labels contain ID numbers and figures that identify the model of the window, the type of glass used in the window, when the window was manufactured, and other necessary identification information.

This information can also be used to complete the Andersen product identification online worksheet. Input the product information into the online worksheet found on the Andersen website, and the online system will provide all of the relevant product information based on the ID label.

You can visit the Identify Andersen Window Products page for more information.

How To Determine Andersen Window Types

Another way to identify Andersen windows is to recognize the type of Andersen window by design. Design style can help to point you in the right direction for more accurately identifying the window model.

Andersen produces a wide range of windows, but they each have distinctive features. Andersen windows can be identified by window type and design. The four main types of Andersen windows are casement, double-hung, awning, and gliding windows. Each of these window designs has multiple sub-types.

The design of Andersen windows is a visual way to identify the window itself. Andersen window designs are iconic in the industry, and they have used many of the same designs since the company began.

By simply knowing what to look for, the design of the window can help you narrow down the identification of the window, which can be completed by ID labels or etched logos on the window.

Let’s go over the main Andersen window designs to help you identify your older Andersen windows:

Andersen Casement Windows

Andersen casement windows are a trendy design usually installed in kitchens or other rooms where reaching out to open a window may be difficult.

These windows are effortless to open due to their side hinges. These windows open from left to right or right to left, and they leave a gap on the hinged side when opened.

These windows are always vertical and rectangular and can be up to 8ft tall. These windows offer maximum ventilation as the entire window opens, leaving no portion of the window blocking the window opening.

Andersen Double-Hung Windows

These iconic Andersen windows are versatile and very commonly used throughout houses and other buildings.

The windows slide open and closed vertically, rather than swinging open or closed from inside to outside.

Double-hung windows are so-called because the top section and the bottom section of the window can slide open. These windows can be opened halfway by sliding only one sash open, or they can be opened completely by sliding both halves of the window into the center of the window frame.

These windows are relatively large, and they are always a wide vertical rectangular shape. In addition, these windows often have latches to keep them locked and can be filled with various types of decorative struts within the window frame.

There are single-hung variations of the same Andersen window design that only open from the bottom half of the window.

Andersen Awning Windows

Andersen awning windows are relatively small, square, or rectangular-shaped windows that are usually placed high up.

These windows are designed for air ventilation and circulation, and their hinge design makes it possible for these windows to be opened during rainfall.

The awning windows that Andersen produces are designed with a top-mounted hinge. This hinge design means that awning windows open from the bottom outward.

These windows latch at the inside bottom and are pushed open from the bottom when the latch is released. The fact that these windows open from the bottom outward means that they are perfect for promoting airflow and circulation, and they can be opened during rain because the window blocks any rain from coming through the opening.

Andersen Gliding Windows

Another iconic window design from Andersen is the gliding window design. This window does not feature any hinges, and it does not swing open like other window types, but rather the gliding window slides open from side to side.

Andersen gliding windows open horizontally to allow for full top-to-bottom ventilation. These windows are usually square, and only one side of the window slides open.

These windows are often found in bedrooms and living rooms because they offer excellent ventilation, and their large size allows a lot of natural light into the room.

Andersen gliding windows are one of the most popular window designs, and many homes are equipped with this type of window.

Other Types Of Andersen Windows

Andersen produces many various types of windows. The four designs listed above are the main Andersen window types that are most commonly used, but Andersen is not limited to these designs only.

Other window designs by Andersen include bay windows used in sunrooms and nooks, pass-through windows installed at the same height as a countertop, picture windows that do not open at all, and specialty windows that are made to be various shapes.

All of the types of Andersen windows that we have listed can be identified by the way they look. You can more accurately confirm the identification of the window by using printed labels or etched window labels.


Andersen windows are iconic, high quality, and long-lasting. These windows are found in many homes and other buildings, and they are designed to be a cut above the rest.

When it comes time to replace an Andersen window, it is important to correctly identify the window, especially if it is an older model.

The best way to identify Andersen windows is to locate the etched Andersen logo on the window glass that provides the product number, glass type, and year of manufacture to identify the window correctly.

Product labels are the best way to identify an Andersen window, but they are only present on windows from 2007 onwards.

Any model numbers or manufacturing dates can be used to identify the window using the identification tools on the Andersen website.

Andersen windows are made with iconic designs that can also define features that help identify the window type. All of the Andersen window designs are available for viewing on their website.

Look for these methods of identification, and you will accurately identify your Andersen windows easily and quickly!
