The more I watch this, the more I'm convinced it's fake. Watch the door that hits him from behind, it burst before it even hits him, and it barely touches his butt. Which is hardly hard enough to break glass.
Yes, there's the theory that it warps to the point of breaking, but it hardly warps at all, too. It almost looks like it's "blown" in classic Hollywood style, with the charges in the frame, part of which falls off.
