3M invented window films 50 years ago, and we’ve spent the past five decades innovating and improving them. As a world leader in adhesive and film technologies, our films enhance products you use every day – laptops, TVs, cell phones and more. When rooms are too hot or you notice that your energy costs are trending skyward, 3M™ Window Films can help increase tenant comfort, conserve energy and even increase safety and security. Our films offer enhanced protection from accidents, natural disasters, break and entry, bomb blasts and flying glass fragments. They could also simply help upgrade your glass to code.
