Detailed description
Security and confidentiality in businesses and in the private/public sectors are key concerns. To effectively combat prying eyes on your screens, choose this polarizing film. With this privacy filter, you can maintain the transparency of your windows while ensuring the protection of your data on digital screens. Positioned directly on the glass surface in question, it effectively protects your data from view by blurring your LCD screens. Please note that if you have an OLED or Plasma screen, you must test the film before purchasing it using a free sample, as it may not work on these types of screens.
The visibility of the glass is maintained on both sides: only the screens are impacted by the "blackout" technology. The strong point of this innovative solution is that the transparency of the glazing is maintained and therefore the brightness of your rooms and offices is maintained.
Thanks to this feature, this film is particularly popular in meeting rooms, offices, open spaces and sensitive areas such as banks and government offices. Polarising privacy film is regularly installed on the glass walls that separate a reception area or corridor from an office. The installation of such a film may be necessary to comply with the RGPD.
Please note that the direction in which this polarizing film is laid is crucial to taking full advantage of its properties. Depending on the type of screen you're using, the result may or may not work if the film is applied vertically or horizontally. To determine the film's direction of application, we strongly advise you to request a sample and test the film on each screen.
When applying the film, it is essential to apply it to the inside of the glass in the room. Otherwise the film may not work. We also advise you not to superimpose this film with another one: decorative for example. If in doubt, do not hesitate to contact one of our advisors.
Due to its very specific composition, we recommend the following precautions for use:
• Cut the film before installation to avoid tearing it (we can cut it to the exact dimensions in advance upon request for a quote)
• Unroll the film 1 day before installation to avoid shape memory
• Reduce the soap concentration and wet thoroughly during installation
• Use a suitable squeegee to avoid scratches
We strongly recommend that you order a free sample of this polarizing film.

Each computer/telephone screen has a different calibration, so there may be a difference in color and/or texture.

Frequently asked questions
-
How do I apply window film?
With a little patience and attention to detail, and by following the installation instructions carefully, you can install your window film yourself. For large surfaces (bay windows, for example), we recommend two people.
Find out how to apply self-adhesive films in this article.
Discover the electrostatic film installation tutorial in this article.
If you don't want to do the installation yourself, don't hesitate to ask for a quote.
-
How do I remove my window film?
Just pull at a gentle angle. If you have electrostatics, it's even easier.
Here's a tutorial on how to remove adhesive window film.
You can also find out how to remove and store your electrostatic window film.
-
What's the difference between opaque and frosted film?
The frosted film opacifies while allowing light to pass through, for maximum luminosity.
The opaque film will opacify and stop the passage of light: you'll lose luminosity.
-
Can I order a specific cut (round, half-sphere, etc.)?
Yes, we can. All you have to do is go to the quotation form, and indicate :
- The product reference concerned
- Type of glazing
- Glazing dimensions
- Whether or not you need an installation service
-
How can I see without being seen?
Two-way mirror effect films allow you to see without being seen, when the light is stronger outside than inside.
It works by balancing the light: the mirror effect is always on the brighter side.
-
Do frosted films affect the brightness of a room?
No, if you choose a translucent or white frosted film, you won't notice the difference.
In concrete terms, with a measuring tool there may be a small variation in brightness, but imperceptible to the naked eye. This is one of the advantages of frosted film, unlike mirror-effect film! 😉
Be careful, if you order a tinted frosted film (gray, black, blue, red, etc.), the passage of light may be affected. In this case, you may lose a little luminosity.
-
What's the difference between white and translucent frosted film?
White frosted film will be slightly more opaque than translucent frosted film.
For example: with a translucent film like DEPOLI-301i, you'll be able to see that there's someone behind you, but it'll remain very blurred: you won't be able to tell whether it's a man or a woman.
With a white frosted film like DEPOLI-300i, you won't notice anyone's there.
