The double pane window glass can also be broken many times under a number of different circumstances. It is really important to replace these broken double pane window glasses, simply by following the instructions mentioned below.

Removal of Panel

The first step is to decide what kind of replacement pane you would require. So, you would need to remove the full glass panel and take it to the supplier. A stationary panel needs to be taken apart too with the help of a screwdriver to remove all the screws, located on the bottom of the stationary panel. But if it is an ordinary panel and not a stationary one, it would be much easier to remove. All you need to do is to firmly hold the bottom of the panel, pulling out and lifting as well at the same time. It will come out easily.

Choosing Panel

The next step is to take the glass panel to the supplier or specialist, as they will be able to help you to choose the right kind of replacement pane required for the window. They will be able to evaluate the thickness and size of the replacement pane. Thus, take the panel to a glass shop or any supplier and allow them to help you choose the right replacement panel. They would also help you in choosing the best manufacturers and provide you with the necessary supplies that you would require while replacing the window panes.

Removal of Old Glass Panel

Once the replacement pane has been purchased by you, you would have the remove the old panes from the frame and disassemble the frame by just removing the screws, which is holding the frames together. Tap on the frame, where the old glass pane is located with the help of a rubber mallet. If this step is performed in the right way, then the glass pane will loosen itself and come out from its frame in a gentle way without causing any further problems to the rest of the glass panel.

New Double Pane

Place the new pane (frame) in the right way, so that it is lined up correctly with the rest of the panel. You can also reinstall the screws back into the pane and tighten each and every screw, just to be sure.


While replacing the double pane windows, you also require sealing the frame. Make sure that you do not end up displacing the double glass panes. Just seal the panes into the frame by applying a thin line of caulk right between the glass and the frame. This will help in protecting the window against any kind of moisture and build a secure base for the double glass pane to rely on.


The last step is the simplest step. All you require to do is, set the frame in the right position into the window. Don't forget to replace the screws you removed previously during the process.

Lastly, always make sure to ask for a warranty before purchasing any kinds of items from the manufacturer or the shop. This will help if getting you covered for all the problems which can occur during the replacement of the double-pane window glass.
