As the name suggests, this film allows clear visibility from one side, while someone on the other side basically sees their own reflection, and does not see inside.

Nobody wants neighbors or strangers peeking inside their home, and one of the best ways to get more privacy during the day is with the help of a one way mirror film.

The benefits of one way mirror film

  • Increased privacy — people outside will no longer be able to see inside the home during the day
  • Protection against UV rays — the film also blocks up to 99% of the dangerous rays of the sun that can cause damage to people or furniture
  • Reduced heat — by reducing the heat that enters the room, you also save money on air conditioning
  • Cheaper than privacy glass
  • Easy application and removal

How does a one way mirror film work?

The one-way property of tinting films is based on the fact that one side is more bright, while the other is dark. A good example — interrogation rooms in the movies, where the criminal sits in a bright room while the witnesses are looking at him from a darker space, hidden from his sight.

When it comes to houses, the setting doesn’t have to be this dramatic, but the benefits of a one-way mirror film are very useful in daily life. As long as the outside is bright and the interior is a bit darker, it is impossible to sneak peek into the house out of curiosity or for any other reason.

On very bright and sunny days, tinted windows act as partial mirrors. But during the night when the situation is opposite and the home interior has more lighted, the privacy effect fades away.

Where can you use a one way window film?

A film that offers more privacy and protection against UV rays can be beneficial in a multitude of places:

  • Outside windows of the house
  • Garages
  • Storages

Frequently Asked Questions

Does one-way mirror film work at night?

Unfortunately, the privacy effect is lost during the night if the light inside is stronger than that outside. But in most residential areas the outdoor lighting is strong enough to create glare for the privacy effect to be maintained. You can also add some outdoor solar-powered lights to maintain privacy, or just install some blinds or curtains to use at night.

Does one way film block light?

The film does not block the light completely like a curtain would do, it just slightly reduces it. But what the film does is to block 99% of the harmful UV rays that are causing sunburns on our skin or causing the furniture and upholstery to fade.

How much light is needed for one-way films to work?

The mirror effect appears even on windows without any film on them. You probably remember a situation where you were walking on the street on a very sunny day, and you were able to see your reflection in the windows of homes, stores, or cars. Or maybe you were sitting inside during the night with bright lights turned on, and when you were looking into the windows you would see your reflection. One-way window films are simply enhancing this already existing effect. In order for the film to do its job properly, you need a light ratio of 1 to 4. That means that the side where you want the mirror effect to occur needs to have 4 times more light than the other one.

Is one way mirror film applied on the inside or the outside?

The privacy film is usually applied on the inside of the windows.

Is a one way privacy film the same as auto tint?

Car window films cannot be very dark or reflective in order to comply with the tinting laws. But when it comes to your personal home there are no restrictions, so you can go as dark or as reflective as you want, in order to achieve maximum privacy.
