Mirrored Bronze Privacy Window Film is a deep dyed film with an aluminized metal finish; one side has a reflective mirror finish, while the other has a unique reflective bronze finish. Mirrored Bronze Privacy Window Film rejects heat and blocks up to 99% UV Rays, which in turn helps to reduce energy costs. Mirrored Bronze Privacy Window Film is highly reflective and provides a touch of elegance to any room or office. By combining the metallization process with traditional window film dying methods, it creates a unique window film, with color on the outside and reflective silver mirror on the inside. Mirrored Bronze Privacy Window Film provides maximum daytime privacy; privacy level is determined by the indoor/outdoor lighting. The Mirrored Bronze Privacy Window Film is compatible with standard 1/8 inch clear residential windows including single-pane, dual-pane, and removable storm pane windows. Width:30 in. Length: 100 ft. Packaging:Roll The Mirrored Bronze Privacy Window Film offers maximum privacy during daylight hours; this film relies on proper lighting conditions to produce the desired result. When it is brighter outside than it is indoors, the film will produce a mirrored effect, making it very difficult to see inside; however, in the evening and at night, when lighting conditions are reversed, the effect of the film will also reverse, making it appear to be mirrored on the inside. To provide privacy at night, it is recommended that a light be placed outside of the window or door.
