The film is two-toned: grey on the interior and silver on the exterior. It is the silver side that creates the mirror effect.

Yes. The film can be applied on the interior side of glass doors, windows, partitions, corridors, and even skylight glass, as long as the surface is smooth.

Since the films are tinted, your interior glass will be a shade darker (imagine putting on sunglasses) but your view of the outside will still be visible, only now more comfortable and a lot less glaring. From the exterior, people will only be able to see their own reflection (like a mirror) during the day.

The films require a play in lighting to create the one-way mirror effect. One side must be brighter than the other. The brighter side (the exterior) will not be able to see through the glass, while the darker side (the interior) can clearly see the other side. At night when the lighting is reversed (exterior is dark, while interiors have the lights on), then people from outside will be able to see inside the room.

With the one-way mirror film providing daytime privacy only, use of blinds or curtains can upgrade your windows’ privacy until night time. The combination of the one-way mirror film plus blinds or curtains will allow unhindered views for you during the day and ensure total privacy once your lights are on at night.

This situation may occur for casement or push-out type windows where the glass catches the sun’s rays horizontally or at an angle (less likely for windows in an upright or vertical position), but the sun moves through-out the day, and so the reflection caused is only temporary and goes away as the sun changes its position in the sky.

The reflective properties of the film also prevent a majority of the sun’s heat from entering your windows. It is actually the solar-control film in the market with the highest heat rejection properties, lowering the temperature inside your room by up to 6 degrees C. This means a cooler interior and lesser electricity expenses. At the same time, it protects you from the harmful UV rays of the sun which cause skin cancer and the premature fading of your furniture.
