Hey there! I'm a supplier of aluminium bifold doors, and I know how frustrating it can be when a glass panel in your bifold doors gets broken. But don't worry, replacing a broken glass panel isn't as hard as it might seem. In this blog, I'll walk you through the whole process step by step.
Step 1: Gather Your Tools and Materials
First things first, you'll need to gather all the tools and materials you'll need for this job. Here's a list to get you started:
- Safety glasses and gloves: You don't want any glass shards getting in your eyes or cutting your hands.
- Screwdriver: To remove the screws holding the glass panel in place.
- Putty knife: This will help you remove any old sealant or glazing compound.
- New glass panel: Make sure it's the right size and thickness for your doors. You can usually find the specs in the door's manual or by measuring the old panel.
- Glazing compound or sealant: To seal the new glass panel in place.
- Caulk gun: If you're using a sealant.
Step 2: Remove the Broken Glass Panel
Before you start removing the broken glass, put on your safety glasses and gloves. You don't want to take any chances with sharp glass.


Start by using your screwdriver to remove the screws around the perimeter of the glass panel. These screws are usually located on the inside of the door frame. Once you've removed all the screws, gently lift the broken glass panel out of the frame. Be careful not to let any glass shards fall out and scratch the door or the floor.
If there's any old glazing compound or sealant holding the glass in place, use your putty knife to carefully scrape it away. You want to make sure the frame is clean and smooth before you install the new glass panel.
Step 3: Measure and Order a New Glass Panel
Now that you've removed the broken glass panel, it's time to measure the opening in the door frame. Use a tape measure to get the length and width of the opening, and make sure to measure in several places to account for any irregularities. Write down these measurements and take them to a glass supplier or order a replacement panel online.
When ordering the new glass panel, make sure to specify the type of glass you need. For aluminium bifold doors, tempered glass is usually the best choice because it's stronger and safer than regular glass. You'll also want to make sure the glass has the right thickness and finish for your doors.
Step 4: Prepare the Door Frame for the New Glass Panel
While you're waiting for your new glass panel to arrive, you can start preparing the door frame for installation. Use your putty knife to remove any remaining old glazing compound or sealant from the frame, and then clean the frame with a damp cloth to remove any dust or debris.
Once the frame is clean and dry, apply a thin bead of glazing compound or sealant around the perimeter of the opening. Make sure the bead is even and smooth, and use your finger to press it into the frame to create a good seal.
Step 5: Install the New Glass Panel
When your new glass panel arrives, carefully place it into the opening in the door frame. Make sure the panel is centered and level, and then use your screwdriver to replace the screws around the perimeter of the panel. Tighten the screws just enough to hold the panel in place, but don't over-tighten them or you could crack the glass.
Once the panel is secured, use your caulk gun to apply a second bead of glazing compound or sealant around the perimeter of the panel. This will help to seal the panel in place and prevent any air or water from leaking in.
Step 6: Clean Up and Test the Door
After you've installed the new glass panel, use a clean cloth to wipe away any excess glazing compound or sealant from the door frame and the glass. Then, test the door to make sure it opens and closes smoothly. If the door seems stiff or doesn't close properly, you may need to adjust the hinges or the screws.
Tips and Tricks
- If you're not comfortable removing and installing the glass panel yourself, you can always hire a professional to do the job for you. It may cost a little more, but it's worth it for the peace of mind.
- When ordering a new glass panel, make sure to order an extra one just in case. You never know when another panel might break, and having a spare on hand can save you a lot of time and hassle.
- If you're using a sealant to seal the glass panel in place, make sure to choose a product that's specifically designed for use with aluminium doors. This will help to ensure a good seal and prevent any damage to the door frame.
