laminated glass

Laminated glass bonds panes with a plastic interlayer. Holds together when broken; required in glass balustrades above 5m and overhead glazing under AS 1288:2021.

Laminated glass is made by bonding two or more panes of glass together with one or more plastic interlayers (typically polyvinyl butyral, PVB) under heat and pressure. When laminated glass fractures, the fragments adhere to the interlayer rather than falling away, keeping the panel largely intact. This property is critical in overhead glazing (where falling fragments would injure occupants below) and in structural balustrades (where post-breakage stability is required under AS 1288:2021 Section 7). The 2021 edition of AS 1288 made laminated glass mandatory in barriers protecting a fall height above 5 m and in all overhead glazing above occupied areas, replacing monolithic toughened glass in those applications. Laminated glass is classified as Grade A safety glazing under AS/NZS 2208:1996 and satisfies the NCC 2022 Housing Provisions Part 8.4 requirements for human impact zones.
