Gila® Privacy Mirror Window Film features advanced technology and highly-reflective material on the exterior to provide superior daytime privacy while maintaining your view of the outside. This film does not offer nighttime privacy-when it’s dark outside and lights are on inside, the film no longer conceals views. In addition to privacy, Gila Mirror Window Film also blocks heat, reflects UV rays and reduces glare for increased interior comfort. With the Gila Complete Application Kit, How-To videos and Tips, the film is hassle-free to install and perfect for weekend DIY projects.
