Do 3M Window Films cause glass to break?
The application of 3M Window Films will increase the temperature of your sunlit glass, which can increase the stress on the glass edges. The quality of those edges, as well as other determining factors like external and interior shading, the age and history of the glass to which the film is applied, the type of window film used, size and shape of the glass to which the window film is applied, and indoor and outdoor temperatures, all contribute to the potential risk of glass breakage.
3M’s long history of experience with applying 3M Window Films to different types of glass enables Accent Distributing and our network of highly trained and qualified dealers to make proper commercial and residential window film recommendations to meet your needs and minimize the potential for glass breakage. In addition, 3M supports these recommendations with a 5-year (60-month) glass breakage warranty against thermal shock fracture. Should the glass break within 60 months of application, 3M will replace the glass (maximum $500.00), and your 3M authorized dealer will replace the film.
