Contra Vision® Privacy Window Films™ provide and afforable and convenient way to convert windows into one-way privacy glass. An added benefit is a reduction in solar heat gain, glare and UV radiation. This can help offices, public buildings and homes to be more comfortable living environments with lower air conditioning costs.
The lighting conditions at night are very challenging for privacy products. If the inside is illuminated and the outside is dark then the products will lose their one-way vision properties. Contra Vision offers a translucent white perforated film which provides some privacy at night (see below). Shining a powerful floodlight onto the outside surface of the window is another way to maintain privacy, however, this is not a realistic option in most situations. Otherwise blinds or curtains are required.
