- Window glass is called glazing and energy efficient windows with multiple panes of glass are called glazing “systems”.
- Glazing compounds refer to the putty used to seal the glass against the front of the window frame and some of the putty will also squeeze between the glass and the frame.
- Window glazing also refers to the process of applying the putty or glazing compound to the window. The phrase you’ll hear is re-glazing a window. It starts with removing the old, cracked and missing putty. Once the putty is removed, you clean the glass and apply new putty, wait for it to harden from oxidation and then you can paint the window.
- Replacing window glass always includes re-glazing. You can do this yourself for single pane glass. With double or triple pane glass, you want the glass company to do the glazing to get their warranty in case the seal between the glass gets broken.
If you’d like to learn more about re-glazing a window, here’s a nice video, How to Repair Window Glazing, that demonstrates all the steps in the process.
