Double insulated glass can be broken in many circumstances, whether from an overly eager knock or a stray baseball. It is important to replace any broken panes as soon as you notice them in order to prevent any interior moisture damage. If you're good with your hands, replacing your windowpane is as simple as following instructions, without taking up too much of your time or energy.
Remove Window Panel
In order to accurately determine the type of new pane you will need, the entire glass panel will have to be removed and taken to a window specialist. A stationary panel will have to be dismantled using a screwdriver to remove any screws, which are usually located on the bottom of the panel. An ordinary sliding panel is easier to remove. All you have to do is take a firm hold to the bottom of the panel while pulling out and lifting up at the same time. It should slide off easily.
Take Panel to Window Specialist
A window repair specialist will be able to evaluate the size and thickness you will need for a replacement pane or panes in the case that more than one is broken. Take the panel over to a glass shop that specializes in window repair and allow them to take the appropriate measurements to ensure accurate replacement. Window specialists can also help you identify the manufacturer and provide you with any supplies you will need to replace the window pane(s) yourself, which makes the project at hand much faster and easier. Be sure to ask for a warranty so you are covered should any problems occur during installation.
Remove Old Pane
Once you have received the replacement panes from the specialist, the next step is to remove the old panes from their frame. Disassemble the frame by removing the screws that hold the frame together. Gently tap on the frame where the old pane is located using a rubber mallet. If done correctly, the pane will gently loosen itself from its frame without causing further damage to the rest of the glass panel.
Set New Pane
Gently place the frame so that the replacement pane is lined up correctly with the rest of the panel. Reinstall the screws back into the frame and tighten each screw to the appropriate tension.
Seal the Frame
Being careful not to displace the glass panes, seal the panes into the frame by running a thin line of caulk between the glass and the frame. This step protects against moisture buildup and provides a secure base for the glass pane to rest on.
Reinstall the Frame
Set the frame back into the window. Replace any screws that you removed previously and you are finished.
