ADVANCED UV BLOCKING PROTECTION – This anti-glare window film is designed to block out harmful UV rays which can impact eye and skin health, heat insulation, and energy savings for intense summers and year-round coverage. STATIC CLING APPLICATION – This advanced window tint film uses static cling to easily attach to your window and doesn’t use adhesives for a faster, bubble-free placement. It can also be removed with no sticky residue! DAYTIME PRIVACY PROTECTION – Applying our mirror window film to your windows keeps prying eyes from looking in during daytime while letting natural lights in, and outside glass shows mirror reflective effect. NOTICE: When the inside light is stronger than outside at night, the film CAN NOT provide privacy, and the mirror reflective effect will disappear. Do remember to draw curtain during night. MULTIPURPOSE HOME OR OFFICE USE– Our one way privacy window film can be used in living rooms, waiting areas, bedrooms, attics, enclosed porches, and anywhere windows where you want to block UV light or intense heat. (Not applicable to double pane glass)
