Laminated Insulated Glass Units are double or triple-glazed windows or glass panels where the individual glass panes are bonded together with a layer of polyvinyl butyral (PVB) or other adhesive material. The purpose of this lamination is to enhance safety and security. In the event of breakage, the glass fragments tend to adhere to the interlayer, reducing the risk of injury from sharp shards and maintaining some level of transparency. Laminated insulated glass units also provide sound insulation and are used in various architectural and construction applications.
