The blocks have achieved a 2-hour fire rating with a minimum thickness of 4 inches. They are suitable for retrofit of existing structures or introduced as a key part of new construction to mitigate against intentional attacks, accidents and natural disasters and implemented in a wide variety of sectors. Pretty Cool!
