How to Replace Glass in Andersen Casement Windows: A Step-by-Step Guide

Andersen casement windows are known for their durability and high-quality construction. However, accidents can happen, and you may find yourself needing to replace the glass in your window. In this blog post, we will provide a comprehensive, step-by-step guide on how to replace the glass in your Andersen casement window. This guide will be helpful for both DIY enthusiasts and professional installers alike.

Tools and Materials Needed

Before you begin, gather the following tools and materials:

Safety glasses

Gloves

Screwdriver

Utility knife

Replacement glass (ensure it's the correct size and type for your window)

Glazing tape or silicone sealant

Painter's tape (optional)

Step 1: Remove the Sash

First, you'll need to remove the sash (the part of the window that holds the glass) from the frame. To do this, follow these steps:

1. Open the casement window fully.

2. Locate the hinge at the bottom of the window. You should see a small clip on the hinge. Using a screwdriver, lift the clip to release the bottom of the sash.

3. Repeat this process for the hinge at the top of the window.

4. Carefully lift the sash out of the frame and set it aside on a flat, stable surface.

Step 2: Remove the Old Glass

Now that the sash is removed, you can begin removing the old glass. Follow these steps:

1. Put on your safety glasses and gloves to protect yourself from sharp edges.

2. Use a utility knife to cut through the glazing tape or silicone sealant that holds the glass in place. Be careful not to damage the sash while doing this.

3. Carefully remove the old glass from the sash. If it's broken, use painter's tape to hold the pieces together and prevent them from falling out.

Step 3: Clean the Sash

Before installing the new glass, you'll need to clean the sash to ensure proper adhesion. Follow these steps:

1. Use a utility knife to remove any remaining glazing tape or silicone sealant from the sash.

2. Wipe down the sash with a damp cloth to remove any dirt or debris.

3. Allow the sash to dry completely before proceeding.

Step 4: Install the New Glass

Now that the sash is clean and dry, you can install the new glass. Follow these steps:

1. Apply a continuous strip of glazing tape or silicone sealant around the perimeter of the sash where the glass will sit. Ensure there are no gaps in the tape or sealant.

2. Carefully place the new glass onto the sash, ensuring it's properly aligned and seated in the tape or sealant.

3. Press down gently on the glass to ensure proper adhesion with the tape or sealant. You may use painter's tape to hold the glass in place while the sealant cures, if necessary.

Step 5: Reinstall the Sash

Once the new glass is securely in place, you can reinstall the sash into the window frame. Follow these steps:

1. Carefully lift the sash and align it with the hinges on the frame.

2. Lower the sash onto the hinges, ensuring the clips engage properly.

3. Close the casement window and check for proper operation. The window should open and close smoothly, and the glass should be secure in the sash.

Additional Tips and Tricks

When ordering replacement glass, ensure you provide the correct measurements and specify the type of glass needed (e.g., tempered, low-E, etc.).

If you're unsure about any part of the process, consult a professional window installer for assistance.

Regularly inspect your casement windows for signs of damage or wear, and address issues promptly to maintain their performance and appearance.

With this step-by-step guide, you now have the knowledge and confidence to replace the glass in your Andersen casement window. Whether you're a DIY enthusiast or a professional installer, this guide will help ensure a successful and efficient glass replacement process.

INSPIRATION & SOLUTION

This newly built private house is in Sydney, Australia. The area occupied by the fenestration system in our scheduled design drawings was up to more than 110 square meters. A wide range of design details made the perfect mix of modern aesthetics and traditional sophistication, the simulated vertical hung windows with tilt & turn opening systems in this home are absolutely breathtaking. SDLS (Simulated Divided Lites with Spacer Bar) brings some historical vintage feeling to the whole building without losing any energy saving performance. Long narrow fixed windows creating larger-than-life expenses, coupled with German high-end systems made this project stand out from the rest.

Simulated Hung Window with Tilt & Turn Openings

The client's idea was to maintain a certain vintage feel, and our aim was to meet the energy efficiency needs and standards of modern houses as much as possible while maintaining a retro design. 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.

Large Energy Efficient Fixed 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.

Every window’s placement and shape not only add to the uniqueness of this home but also provide a more energy-saving ability for the owners.

Doorwin energy-efficient integrated glazing units feature double-pane glass, warm-edge spacers, argon gas fill, Low-E coatings, and fully tempered glass, they can not only create a comfortable and natural indoor environment but also save electricity bills and heating bills of more than 100 USD for the owner, it’s a real bargain compared to choosing a regular glazing set.
