I believe all windshield glass in the US is laminated. That way, if you are in an accident and your face was to hit the windshield, it would not be severly cut. The plastic film on the inside would be a barrier between you and the glass that is breaking. And to be even more specific, the laminated glass is also tempered so it will shatter in small pieces and not large shards that can cut thru the plastic lamination.
