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.

Does this film provide privacy (during daytime)? / Can people see in from outside?

This film has a lighter shade of tint, so people would be able to see in through the window. This film can be used for having some heat reduction while keeping the interior visible from outside or allowing more light to come inside.

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.

Is the film applied on the interior or exterior side of the window?

This film is intended for the interior side.
