| "Okay, now, we all know that the number one cause of workplace accidents is Superman crashing through office windows mid-fight. That's a simple fact. But now this glass is made of Kryptonite. So if he flies close to it, his powers will weaken, and he'll safely bounce off." |

A Kryptonite Window is a Wayne Security prototype developed by Ron. It was created to prevent Superman from crashing into offices and causing incredible damage. If Superman came near the window he would only safely bounce off of it. However, the design has major flaws including the fact that it prevents Superman from entering to help the people inside and it is easily breakable.
