Mastering Andersen Casement Window Parts: A Comprehensive Guide

Andersen casement windows are a popular choice among homeowners due to their durability, energy efficiency, and timeless design. However, like any other window type, they may require maintenance or replacement of certain parts over time. In this comprehensive guide, we will explore the various Andersen casement window parts, their functions, and how to maintain or replace them to keep your windows in top-notch condition.

Understanding the Anatomy of Andersen Casement Windows

Before we dive into the specific parts, it's essential to have a basic understanding of the components that make up an Andersen casement window. Here are the primary parts of a casement window:

1. Frame:The structural support that holds the window in place, consisting of the head, jamb, and sill.

2. Sash:The part of the window that holds the glass and can be opened or closed.

3. Hinges:The pivot points that allow the sash to swing open and closed.

4. Operator:The mechanism that controls the opening and closing of the sash.

5. Locking mechanism:The system that secures the sash in a closed position, ensuring safety and energy efficiency.

Now that we have a basic understanding of casement window components, let's dive deeper into the specific Andersen casement window parts.

Sash Components

1. Glass:Andersen offers various glass options, including energy-efficient Low-E glass, tempered safety glass, and decorative glass.

2. Glazing bead:A vinyl strip that holds the glass in place within the sash.

3. Weatherstripping:A material used to seal gaps between the sash and frame, preventing drafts and improving energy efficiency.

Hinge Assembly

1. Hinge arm:A metal arm that connects the sash to the hinge channel.

2. Hinge channel:A metal track mounted to the window frame, allowing the hinge arm to slide and pivot.

3. Hinge track:A metal or plastic track on the sash that the hinge arm slides in.

4. Egress hinge:A special type of hinge that allows the sash to open wider for emergency exit purposes.

Operator Assembly

1. Operator handle:The part you turn to open and close the window.

2. Operator cover:A decorative cover that hides the operator mechanism.

3. Operator gear:The internal gears that transfer the motion of the handle to the operator arm.

4. Operator arm:A metal arm that connects the operator gear to the sash, allowing it to open and close.

Locking Mechanism

1. Lock handle:The part you turn to engage and disengage the lock.

2. Lock keeper:The part on the sash that the lock engages with to secure the window.

3. Lock bar:A metal bar that runs vertically along the sash, connecting the lock handle to the lock keeper.

Maintaining and Replacing Andersen Casement Window Parts

Proper maintenance and timely replacement of Andersen casement window parts are essential to ensure the longevity and functionality of your windows. Here are some tips and guidelines:

1. Cleaning:Regularly clean your windows, including the glass, frame, and sash, using a mild soap and water solution. Avoid using harsh chemicals or abrasive materials, as they may damage the window components.

2. Lubrication:Periodically lubricate the operator gears, hinge channels, and lock bars with a silicone-based lubricant to ensure smooth operation and prevent corrosion.

3. Inspection:Regularly inspect your windows for signs of wear or damage, such as cracked or chipped glass, damaged weatherstripping, or loose hardware. Address any issues promptly to prevent further damage.

4. Replacement:If any Andersen casement window parts need to be replaced, consult the Andersen window parts catalog or contact an Andersen dealer for assistance. Be sure to provide the specific window model and part number to ensure you receive the correct replacement part.

By following these guidelines and having a thorough understanding of the Andersen casement window parts, you can keep your windows in excellent condition for years to come. Remember, regular maintenance and prompt attention to any issues will not only extend the life of your windows but also help maintain their energy efficiency and functionality.

Casement Window


Casement windows are the most common style of window. They feature hinged panels that swing open and closed. Casement windows are available in single panels or multiple panels. The direction a door swings, either to the right or the left, is called the handing. In addition to handing, window are identified as either inswing or outswing depending on whether they open into the house or towards the outside.

Doorwin’s 61S simulated hung windows with tilt & turn openings is a respectful modernization of a classic architectural masterwork.

Why choose the tilt and turn opening method?

Because it generally has better air seals than sliding, single hung, or double hung window frames. Tilt and turn windows form a complete seal when fully closed, this means they are less prone to water leakage, and cold draughts and you’ll keep more of your heating indoors where it belongs. They can be opened in the upper tilt way to ventilate at a minimum opening status and are easy to clean outside of the glass; when there’s a good day, they can be opened as normal inward casement windows.

Our well-crafted bespoke systems enhance the functionality and panoramic view of this modern house.

Huge, fixed glass walls up to seven meters long and two meters high bring great lighting and open views, making it really refreshing to the mind. Five meters high long narrow windows give the whole building a contemporary aesthetic.
