Curved Glass Facade for Nanchang East Railway Station

Curved Glass Facade for Nanchang East Railway Station

Large transport hubs put almost every demand on a glass facade at once: sweeping curved geometry, high thermal and solar performance, strict safety glazing, and — over concourses and escape routes — a fire rating. For Nanchang East Railway Station — one of China’s major high-speed rail hubs (completed 2023, around 2,800 m² of facade glazing) — Dayang supplied the curved tempered glass systems for the facade.

The brief

Nanchang East Railway Station required a double-curved glazed facade combining energy performance with the fire protection that a major public transport building demands. Two curved toughened glass systems were specified for different parts of the envelope.

Glass systems supplied

• Double-curved Low-E tempered insulating glass (IGU). Compound-curved toughened glass with a Low-E coating, sealed into an insulating unit with an argon-filled cavity, for the solar-control and thermal performance the concourse envelope needed. Representative build: 12 mm Low-E double-curved tempered + 12 mm argon cavity + double-curved tempered.
• Cesium-potassium fire-rated double-curved tempered glass. Chemically strengthened (cesium-potassium ion-exchange) fire-rated curved tempered panels for the parts of the envelope requiring fire-resistant glazing.

Both systems follow the station’s curved geometry while meeting the respective thermal and fire requirements — a combination standard flat glazing cannot deliver.

Why it is difficult

Double-curved (compound-curved) glass bends in two directions at once, so each panel is formed to its own radii and must still hold tight dimensional tolerance to assemble into a continuous facade. Adding a Low-E coating and sealing the curved plies into an insulating unit — and, separately, producing fire-rated curved panels — means the bending, coating, lamination/sealing and fire-glass processes all have to land on the same curved geometry. Dayang produces single- and multi-curved tempered glass in-house, which is what lets these functions be combined on curved panels for a project of this scale.
