Glass Options / Laminated Glass

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 into large sharp pieces. This produces a characteristic "spider web" cracking pattern when the impact is not enough to completely pierce the glass. Laminated glass is normally used when there is a possibility where the glass could fall if shattered. In geographical areas requiring hurricane-resistant construction, laminated Heat-Strengthened glass utilizing special interlayers is used in exterior storefronts, curtain walls and doors and windows. The PVB interlayer also gives the glass a much higher sound insulation rating due to the damping effect and also blocks 99% of transmitted UV light.
