Can glass windows crack on their own?
Is Spontaneous Glass Breakage Normal? While rare, spontaneous glass breakage does happen sometimes in double-paned windows, due to the pressurized gas between the panes. It can also happen to tempered glass, which is a tougher type of glass that has been treated with heat and chemicals to withstand high impacts.
Why did my window suddenly crack?
