How do 3M Safety and Security Window Films work?
3M Safety and Security Window Films are designed to make glass shatter-resistant by holding the glass pieces together when broken.
Compared to 3M Sun Control Window Films, 3M Safety & Security Window Films are made with thicker polyester and a much thicker, more aggressive adhesive. 3M Ultra Safety & Security Window Films are unique in the industry; they are built using a special micro-layered polyester technology which increases the films’ tear resistance significantly. The impact and tear resistance of Ultra films outperform all other films of similar thickness.
