Why does the film not stick to the window? / Why did the film fall off from the window a few hours later?

There is a clear "backing liner" layer attached to the actual "film" layer. The backing liner covers the adhesive on the film so that the film does not prematurely stick. When you install the film, the backing liner needs to be peeled off from it.

Can people see in at night? / Why is the interior visible from outside during nighttime?

If lights are on inside, the interior will be visible at night because it is brighter. Curtains or blinds can be closed at nighttime to block view. (During daytime, you can see out while having privacy from outside due to the sunlight outside.)

Why does the window feel warmer after the film has been installed?

This is an expected result. The window with the film installed feels warmer because the film stops some of the heat. If the film is not there, the heat felt on the window would instead enter the room.

Why did bubbles (or spots where film is not adhering properly) form after the film was installed?

This is due to the moisture left inside. The film may appear fine when installed, but afterwards, the water can interfere with the adhesive and cause bubbles to form. Apply firm pressure with the squeegee and push out the water to prevent bubbles.

Can this film be used on dual pane windows?

This film is not recommended for dual pane windows due to the higher heat absorption rate. This can build up heat between the panes, which would stress the window. (Heat absorption is different from heat blocking rate.)
