According to a release from USD 338, the clear security film is designed to help strengthen glass against forced entry and high impacts. The district says the film is attached to the window frame with a high-strength sealant system to help keep the glass from being pushed out or falling inward.

The release says one of the benefits is intrusion delay, intended to make smash-and-grab attempts more difficult.
