tempered laminated glass is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by an interlayer, typically of polyvinyl butyral (PVB), between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. This produces a characteristic "spider web" cracking pattern when the impact is not enough to completely pierce the glass.

tempered laminated glass is normally used when there is a possibility of human impact or where the glass could fall if shattered. When broken by impact, tempered laminated glass tends to remain integral in its frame, minimizing the risk of injury from sharp edges and flying or falling glass particles, and strongly resists penetration by the impacting object or person.

Shopfront glazing and windshields are typically tempered laminated glass. The PVB interlayer also gives the tempered laminated glass a much higher sound insulation rating, due to the damping effect, and also blocks 99% of transmitted UV light.
