Mental Asylum Film

I watched a film a few years back about a young man who got himself committed into a mental asylum to try and break his sister out. As the film progressed many of the patients broke out into the main asylum and went on a rampage. Also I remember the brother was place in a white high security area at one stage, with the most insane people, and was kept behind bullet proof protective glass.

Just wondering what the title of this film was. Thanks.
