Laminated Glass
Laminated glass consists of two or more layers of glass with an interlayer of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). It provides enhanced safety, security, and sound insulation.
Insulated Glass
Insulating glass consists of two glass panes and one spacer layer, forming a sealed and dry air cavity filled with dry air or inert gas such as argon. It features good thermal insulation, sound insulation and anti-condensation performance. With a mature structure and wide application, it is suitable for most architectural windows, doors, curtain walls and skylights.
Heat Bent Glass
Heat bending glass is a kind of curved glass product made by heating high-quality float glass to its softening point, bending it into shape on professional molds, and then cooling it uniformly and slowly.With smooth curved surface, exquisite and transparent appearance, it can be combined with tempering, Low-E coating, laminating, insulating processes to meet architectural safety, energy-saving and aesthetic design requirements.
Bent Tempered Glass
Bent Tempered Glass is a kind of curved safety glass produced by heating glass to softening temperature, bending it into designed curvature, and then quenching it with rapid air cooling. Its strength is 3-5 times that of ordinary glass, with excellent impact resistance, wind pressure resistance and thermal stability. It breaks into small blunt particles, which is safe for people. It is widely used in curved curtain walls, observation elevators, curved windows & doors, skylights, etc.

Why Low-E Curtain Wall Glass Matters in Energy-Efficient Facade Design
Modern commercial architecture continues to move toward larger glazed façades with cleaner visual lines and higher daylight penetration. From office towers and airports to mixed-use developments and luxury hotels, glass curtain walls now play a central role in both building appearance and environmental performance. As glazing areas increase, façade systems
Why Jumbo Laminated Glass Requires Different Engineering Standards in Curtain Wall Projects
Modern curtain wall systems continue moving toward larger transparent surfaces. Airports, commercial towers, hotel atriums, and mixed-use developments increasingly use oversized glass panels to reduce visible framing lines and improve daylight penetration. However, once glass dimensions exceed conventional façade sizes, the engineering requirements change significantly. Large laminated panels introduce additional
