Our Polyvision® Switchable Privacy Film and Switchable Privacy Glass is a revolutionary new product with consumer’s comfort in mind. What is Polyvision® ? Simply put, it is an opaque white smart film, laminated between glass. It can be changed at the flip of a switch into a clear glass window, which provides easily-controllable, when-you-need-it privacy and security, and works in both interior and exterior installations. The switchable privacy glass also performs great as a rear-projection screen for slideshows as well as a white-board, which maximizes its use for classroom or conference room applications.
