Due to the two-sided metal coating, spy mirror films are so highly reflective that it is impossible to see through from the outside in, but very well from the inside out. We offer spy mirror films in silver and bronze, available both for indoor and outdoor use. A prerequisite for privacy protection from the outside is that the room interior is darker than the exterior – imagine the spy mirror glass in offices of food markets. One can keep an eye on the market from there; however, the observer itself is not seen. Because our spy mirror films are included in the category of sun protection films, these come with a 99% UV protection as well.
