How does 3M Sun Control Window Film work

3M Sun Control Films are precision engineered to reduce the amount of solar heat transmission through window glass, by increasing absorption or solar reflection through the glass. Ultra-violet protection in the film’s adhesive system blocks up to 99% of UV rays – the main cause of fading.

3M Security Window Film is designed to deter forced entry by holding shattered glass together when a window is broken. Security window film is an extremely effective deterrent – often forcing thieves to select an easier target.
