R20 Mirror Intense Internal One-Way Mirror Film – Lite Solar
R20 Mirror is an internal window film with an intense one-way mirror effect. After installation on the room side of the glass, it creates a silver, reflective surface that helps limit visibility into the room.
The effect is strongest when the side from which privacy is needed is brighter than the room interior.
R20 Mirror internal film is intended for users who need a strong privacy effect but do not require the total screening level of R10 Mirror. It is suitable for interior-side installation and provides a reflective finish on the glass.
How the one-way mirror effect works
The film works because the brighter side of the glass becomes more reflective. When there is more light outside the protected room than inside it, visibility into the room is reduced while people inside can still observe the other side.
If the light inside the protected room is stronger than on the other side of the glass, the privacy effect may be reduced. This is a normal feature of one-way mirror films.
