Glass windows may also develop stress cracks. Stress cracks are typically caused by drastic temperature changes and can quickly spread across the entire window if they are not addressed. To stop stress cracks from occurring, score an arc of a tiny size with glass cutters close to the crack. This stops the crack from spreading, and can reduce the size by a day or two.
Examine the frame of the damaged window to determine the size of the new pane. It should be slightly smaller than the opening to allow for expansion and contraction, and to compensate for any imperfections in the glass or frame.
