Is Bullet or Forced Entry Resistance More Critical?
Typically when people think of a highly secure door, they think bulletproofing is the most important feature. It is reasonable to presume that if a door can stop the explosive force of a bullet than it can certainly stop lesser attacks from a perpetrator. In fact, this isn’t the case: forced entry resistance is a separate and generally more important factor.
A human attacking a door with various tools is the greater threat, in most cases. Unlike a bullet, a person can calibrate their movements precisely and use leverage – a bullet is sharp and travels at incredible speeds, but is lightweight and moves linearly.
