Hey there! As a supplier of Black Aluminium Internal Glass Doors, I often get asked about how to replace the glass in these doors. It's a common issue, whether the glass has been damaged or you just want to upgrade it. In this blog, I'll walk you through the process step by step.
Step 1: Gather Your Tools
First things first, you'll need to gather the right tools for the job. Here's a list of what you'll need:
- Safety glasses
- Gloves
- A putty knife or flat - head screwdriver
- A glass cutter (if you're cutting a new piece of glass)
- Measuring tape
- Silicone sealant
- A new piece of glass that fits your door
Safety first! Make sure to wear your safety glasses and gloves throughout the process to protect yourself from any sharp edges or flying glass shards.


Step 2: Remove the Old Glass
The next step is to remove the old glass from the door. Start by using a putty knife or flat - head screwdriver to carefully pry out the glazing beads. These are the strips of plastic or metal that hold the glass in place. Work your way around the perimeter of the door, being gentle to avoid damaging the aluminium frame.
Once the glazing beads are removed, you can carefully lift out the old glass. Be extra careful as glass is heavy and can break easily. Place the old glass in a safe place where it won't get knocked over.
Step 3: Measure for the New Glass
Now that the old glass is out, it's time to measure for the new one. Use a measuring tape to get accurate measurements of the opening in the door. Measure the width and height at several points to account for any slight variations in the frame. Write down these measurements and take them with you when you go to purchase the new glass.
When buying the new glass, make sure it's the right thickness for your door. Most Black Aluminium Internal Glass Doors use glass that's around 4 - 6mm thick, but it's best to double - check.
Step 4: Prepare the Frame
Before installing the new glass, you need to prepare the frame. Use a clean cloth to wipe away any dirt, dust, or old sealant from the area where the glass will sit. This will ensure a good seal and prevent any leaks.
If there are any damaged areas on the frame, you can use a small amount of sandpaper to smooth them out. Just be careful not to scratch the aluminium too much.
Step 5: Install the New Glass
Now it's time to install the new glass. Carefully place the new glass into the opening in the door. Make sure it fits snugly and is centered.
Next, apply a bead of silicone sealant around the edge of the glass where it meets the frame. This will help to seal the glass in place and prevent air and water from getting in.
After applying the sealant, insert the glazing beads back into place. Start at one corner and work your way around the perimeter of the door, pressing the beads firmly into the grooves in the frame.
Step 6: Finish Up
Once the glass is installed and the glazing beads are in place, use a clean cloth to wipe away any excess sealant. Let the sealant dry for at least 24 hours before using the door.
That's it! You've successfully replaced the glass in your Black Aluminium Internal Glass Door.
