Notes about the film. Please read to be sure it is suitable for your needs.

During the day-time, when the outside is much brighter than the inside, this film should completely obscure the inside from outside gaze. When the outside is dark, and the inside is well-lit, a person looking in will not see clear details but will be able to form an impression of anything close to the window, and of any movement in the room. The inside-facing surface is slightly textured.

Putting the film onto a window is harder than the sales patter would have you believe, but it can be done.

There are instructions with each roll, but they don't fully express the reality of the struggle. Basically you'll need to be able to do the following:

1. Cut the film to the right size. It has to be completely flush to smooth glass; any overlap to the frame, or any surface defects on the glass will cause the film to peel away fairly quickly. Having some method of cutting a very straight line would would be a good idea (unless your window is curved).
2. Make the window -- both glass and surrounding frame -- dust free and grease free, so that you don't transfer dust or grease onto the film later, in the messy awkward phase of installation.
3. Make the film dust free, because it almost certain collected some while you were cutting it.
4. Put wet film onto wet glass and get it aligned, without getting dust onto it in the process. More than one person is very helpful. Even having a couple of children to hold corners of the film and stop it flapping around while you, the clever and responsible adult, balance precariously on a ladder, will probably be useful. You can't easily slide the film into the correct location; you need to start at one edge and have it aligned before it touches the glass.
5. Get the air bubbles out from under the film. Ideally one person would hold the top edge to keep the film from falling into a heap on the floor, and somebody with intelligence and a good rub technique would gently bring the film into contact with the glass, ensuring that no air gets trapped in the first place. If you've got lots of hands available, I'd suggest starting at the bottom and working upwards. If you're doing this on your own, you'll probably have to start at the top and work to the bottom.

It can be put up by one person; I have done this previously, but it would have been much simpler with two or three people.
