The reason is simple: toughened breaks into thousands of granules; from a roof or overhead canopy those still hurt when they hit you. Laminated breaks but holds, so the glass stays in the frame, the shards stay glued to the PVB, and the void below stays safe.\u003c\/p\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"pr-clsg__faq-item\"\u003e\n      \u003ch3\u003eQ: Is laminated glass fire-resistant?\u003c\/h3\u003e\n      \u003cp\u003eNo. Standard PVB-interlayer laminated glass is \u003cstrong\u003enot fire-rated\u003c\/strong\u003e.

Opportunistic break-ins (the 60-90 second variety) are almost entirely defeated by P2A and above.
