Broken Panes
Double-glazed windows consist of two glass panes, with an air space between them, which is filled with inert gasses like argon and krypton. This helps to keep heat inside your home and blocks cold drafts from entering. Sometimes, windows may become damaged and when this happens, the entire window could require replacement.

This will prevent cracks from getting worse over time, particularly in the winter. You should also cover your work surface in newspapers to stop any broken pieces from falling. After the broken pane has been removed, scrape off any glazing putty or window seal using the help of a putty knife. Then, remove the glazing points with pliers. Then, apply primer that is quick drying to coat the bare wooden surface.
If you can buy a new replacement pane take measurements of the length and width of the channel using a tape measure. Subtract 1/8" from both measurements to take into account the slight movement of the replacement pane. Then, slide the new pane into place and roll thin pieces of glazing compound into the grooved channels. Tap the glass gently using the hammer every 6" or 8" to aid in setting it in place. Be careful not to break it.
