It depends on the film. Some privacy films work day and night; mirrored films only work one way in daylight.
The short answer
Frosted and decorative films give privacy day and night. Mirrored films give one-way privacy in daylight, but at night, with lights on inside, people can see in.
Choosing the right film
Think about when you need privacy. For bathrooms and street-facing rooms used in the evening, a frosted film is the safer choice.
Keeping the view
Frosted bands or graduated films can cover just the part of the window at eye level, so you keep light and sky above.
Frosted & decorative
- Blocks views from both sides, all the time
- Still lets daylight through
- Ideal for bathrooms, front doors and street-facing rooms
Mirrored films
- One-way privacy when it's brighter outside
- Reverses at night when lights are on inside
- Best combined with blinds or curtains for evenings
