What kind of film is best for my privacy and security?

Different window films are designed to address specific challenges, so consider whether privacy or security is your priority. If privacy is your primary goal, a frosted or decorative film is usually the best option for providing privacy and preventing people from seeing through the glass into your space. By the same token, a frosted film also prevents you from seeing out. If your chief concern is security, we recommend a safety and security film. 3M Ultra 800 is a multi-level security film that’s much harder to tear than regular security film.

Window Films for Privacy

For privacy in the workplace, there are a variety of window films to consider.

  • Smart Film

    Best for privacy on demand. This film transitions from clear to frosted glass with the flip of a switch, press of a button, or from your smartphone using an app. When you need privacy, simply turn the Smart Film on to block outsiders’ view inside your space. Switch the film off to create an open-space feel when confidentiality is not a priority.
  • Casper Cloaking Film

    Best for obscuring digital screens. Casper cloaking film is transparent, allowing passersby to see into a room, yet it obscures their view of wall-mounted and large LED displays. The screens are visible as usual to everyone inside the room but are cloaked to outsiders. Basically, screens will appear black to anyone on the outside of the room.
  • 3M Fasara and Crystal Glass Finishes

    Best decorative films for privacy. These decorative films instantly elevate the look of any interior glass surface. With dozens of finishes, patterns, textures, and opacities to choose from, you can choose not only the design aesthetic, but also the level of privacy you want in your space. These films are ideal for glass partitions, walls, doors, and windows. 

Window Films for Security

3M offers a variety of products designed specifically for enhancing the safety and security of your windows. These films are designed to hold glass fragments together even when it breaks. This reduces potential injury from flying glass during severe weather and creates a stronger barrier to delay and deter criminals from entering the space. 3M Safety and Security Window Films are available in clear, safety-only versions, or as a combination film with both sun control and safety features. Pair your security film with an Impact Protection Attachment (IPA) system for ultimate protection. The IPA system anchors your tinted window to the window frame to prevent the entire window from being forced inward.
