This article looks at interlayer performance for coastal cruise-terminal glazing, using Shanghai Wusongkou International Cruise Terminal as a climate brief rather than a supply claim. Salt air, humidity, wind, and ultraviolet radiation demand a laminate that stays clear and bonded, with fragment retention and ultraviolet stability. Acoustic interlayers and thermally capable insulating units are discussed as ways to keep a long, busy hall comfortable without condensation or bond failure.
