Do 3MTM Window Films cause glass to break?

The application of 3M^TM Window Films will increase the temperature of your sunlit glass which will increase the stress on the glass edges. The quality of those glass edges and several other factors (external shading, interior shading, glass history, type of film, size/shape of glass, indoor/outdoor temperature) all contribute to the potential risk of glass breakage.

3M^TM‘s forty plus years of experience with applying 3M^TM Window Films to different types of glass enables us to make proper film/glass recommendations and minimize the potential for glass breakage. In addition, we support these recommendations with our 60-month glass breakage warranty against thermal shock fracture. Should the glass break within 60-months of application, 3M^TM; will replace the glass (maximum $500.00), and the dealer will replace the film.
