What Is Cloaking Film?
Cloaking Film to Protect Sensitive Data in Glass-Walled Spaces


Modern offices, healthcare facilities, financial institutions, and government buildings increasingly rely on glass walls and windows to create open, collaborative environments. While visually appealing, transparent glass introduces a serious challenge: screen visibility and data security. Confidential presentations, financial information, patient records, and proprietary business data displayed on digital screens can be easily seen by unintended onlookers.
Traditional privacy solutions such as blinds, curtains, or frosted window films block visibility entirely, eliminating natural light and undermining the openness that glass architecture is designed to provide.
CoolVu Cloaking Film solves this problem with advanced optical technology—delivering true screen privacy without sacrificing transparency.
Cloaking Film for Screen Privacy and Data Protection
Cloaking Film is a specialized architectural window film designed to selectively block the light emitted by digital displays while allowing normal visibility through glass. When applied to glass walls or windows:
Digital screens appear completely black to anyone outside the room
People, furniture, movement, and body language remain fully visible
Screens remain perfectly clear and readable from inside the room
This creates an ideal balance between openness, collaboration, and confidentiality.
How Cloaking Film Works
Cloaking Film uses advanced optical filtering technology to block polarized light wavelengths produced by LED and LCD screens. Digital displays emit specific light oscillations, and the film is engineered to filter only those oscillations—without affecting surrounding visible light.
The result:
From outside the glass, screens appear powered off or black. From inside, users experience normal brightness, clarity, and color accuracy.
