Do Guardian window films cause glass to break?
No, Guardian window films alone do not cause glass to break. However, we do understand that the application of Guardian 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 factores (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.
Guardian's extensive experience with applying window films to different types of glass enables us to make proper film/glass recommendations and minimise the potential for glass breakage.
