1. Remove the old glass

The first step to replace a windowpane in a metal frame is to remove the old glass. Make sure you are wearing protective gloves and remove the glass carefully. It might be difficult to pull the glass out due to the silicone that is holding it so if needed, break it down into smaller pieces or remove the silicone first so you can take it out easily. If you decide to remove the silicone you’ll need a screwdriver to remove the strips. Be cautious not to get cut and hurt during this process.

2. Measure window size

The second step is measuring. This also needs to be done carefully so you don’t end up with glass that’s too small or too big. Measure the height from the middle, right, and left sides within the smallest measurements you have, and then measure the width of the glass pane. Lastly, measure it diagonally. Once you have your measurements, you can order a new pane of glass.

3. Setting up new glass panes and strips

Aside from the glass, you’ll also need to buy new strips which can be purchased at stores like Home Depot or any other home improvement store. Once you have the new window glass and the strips, you’ll need to connect them together. Make sure you are adding silicone as that will help stick the glass to the strip. Slide the finished product into the aluminum frame.

If you need to know how to replace a windowpane in a metal frame connected by screws, keep reading. Before you remove the window assembly, you should put on protective gloves and try to remove as many large glass pieces as possible. Aluminum frames come with fixed panes that are tightened by screws, and you’ll need a screwdriver to remove screws which are usually hidden by plugs. The screws need to be loosened enough so that it’s easily removed.

2. Dissembling the aluminum frame

Once the screws are loosened up, remove them. Since aluminum frames press the glass between the outside and inside segment of the frame, you need to remove screws that are holding two frame parts together. Once you do that, there is usually a rubber gasket that surrounds the glass. Try to remove it carefully so that you can reuse it. To remove small pieces of glass you can dampen a cloth and run it around the area where the glass pane was. Once this section is done, do the measurements for the new glass pane and order it/buy it.

3. Set up the new glass pane

Once you have the new glass pane, carefully set the rubber gasket around it and insert the glass pane into the frame. To reassemble it, follow the reverse order on how you took it apart—tighten the screws so that the glass pane is secured and then place it back to the window. Put the remainder of the screws back for additional support.

Sliding window glass panes might seem difficult to remove, but that’s not always the case. Since sliding windows have sash stops in window corners, the first thing you want to do is remove the sash stop. This will allow the sash to pop up so that you can pull the glass pane out.

When changing a glass pane in sliding aluminum windows, the window must be taken down to replace the glass. Once you’ve removed the sash, you can get the glass pane out of the aluminum frame by using a scraper. Make sure you are doing it carefully so you don’t damage the frame. When the frame is removed, remove the excess silicone to get the glass pane out.

3. New Glass Pane Placement

Like the other aluminum window types, you’ll need to measure the size of the new window. Once you have it ready, apply silicone to the same place as before and attach the new glass window pane. Add some more silicone and put the aluminum frame pieces together. There’s no need for screws, strips, or anything similar because the silicone will hold everything in place. Once everything is done, put the window back in its place and set up the sash stop.
