Float glass has become the preferred material for building curtain walls, mainly determined by its unique production process and excellent performance, as follows:

1. Excellent physical properties

Float glass is formed by tin liquid floating forming process, forming a glass strip with uniform thickness (tolerance within ± 0.2mm) and smooth surface, avoiding the wave like defects of traditional glass. Its impact resistance is higher than that of ordinary glass, and it can withstand greater external impacts, improving the safety of the curtain wall. At the same time, the high transmittance (ultra white float glass transmittance exceeding 91.5%) and low reflectivity characteristics not only meet the needs of natural lighting, but also reduce light pollution problems.

2. Diversified processing adaptability

Float glass can undergo deep processing such as coating, coloring, and tempering to expand its functionality and decorative value. For example, after being coated with a metal film, Low-E glass can be made, effectively regulating the thermal performance of buildings; Ultra white floating glass, with its crystal clear appearance, has become the preferred material for high-end curtain wall design. In addition, the wear-resistant and scratch resistant properties of the surface extend the maintenance cycle of the curtain wall and reduce the cost of use.

3. Process stability and environmental friendliness

The raw material ratio (quartz sand, soda ash, etc.) and high-temperature melting process ensure the chemical stability of the glass and adapt to long-term outdoor environments. Compared to traditional processes, float glass technology has lower energy consumption and can recycle broken glass as auxiliary materials, which is in line with the trend of green building development.

4. Multi functional application scenarios

In addition to conventional curtain walls, float glass has shown outstanding performance in special building fields such as solar photovoltaic curtain walls and laminated glass, meeting the integrated needs of modern buildings for functionality and aesthetics.

In summary, float glass has achieved performance breakthroughs through technological innovation, while also combining economy and adaptability, becoming a core material for building curtain walls that balances aesthetics and functionality.
