PNLC smart film is a special type of privacy glass that works a little differently than most. Unlike regular smart film, PNLC film is clear when there's no electricity running to it. This makes it a great option for car windows - you can flick a switch and instantly get privacy without blocking the view when you don't need it. It's a new technology, so the price tag is still a bit high, but it's becoming more affordable. We offer PNLC film in two ways: as an adhesive film that applies existing glass, or laminated between two panes of glass for a more permanent solution.
