Production: Building Strength Through Heat Treatment

• Glass Cutting: Standard float glass sheets are cut to the desired size and shape.
• Heating: The glass undergoes a controlled heating process within a furnace, reaching temperatures exceeding 600°C (1112°F) for most applications. This heating ensures the glass reaches a uniform temperature throughout its thickness.
• Rapid Quenching: Once the target temperature is achieved, the heated glass is subjected to a rapid cooling process typically employing jets of cold air. This rapid quenching induces compressive stress on the outer surfaces of the glass and tensile stress in the interior.
• Stress Balancing: The carefully controlled heating and quenching process creates a favorable stress distribution within the glass. The compressive outer layer strengthens the glass and makes it more resistant to impact and scratches, while the tensile inner layer ensures a predictable breakage pattern for enhanced safety.

• Enhanced Strength: The tempering process increases the overall strength of the glass by several fold compared to untreated float glass. This makes it significantly more resistant to impact, scratches, and bending forces.
• Safety During Breakage: In the event of breakage, SIG's tempered glass shatters into small, blunt fragments rather than large, sharp shards. This significantly reduces the risk of serious injuries, making it ideal for applications where safety is paramount.
• Heat Resistance: SIG's tempered glass exhibits improved thermal resistance compared to float glass. While not designed for extreme temperatures, it can withstand higher temperatures before fracturing.
• Optical Clarity: The tempering process does not significantly alter the optical properties of the glass. SIG's tempered glass remains highly transparent and offers minimal distortion, ensuring clear visibility through the material.

Building Exteriors: SIG's tempered glass is frequently utilized in building facades, especially for doors, windows, Curved commercial spaces, and spandrel panels . Its superior strength and safety profile enable it to endure accidental impacts and resist vandalism effectively.

Shower Doors and Enclosures: Due to its safety features during breakage, SIG's tempered glass is the preferred choice for shower doors and enclosures. Upon impact, it shatters into small, blunt fragments, which significantly reduce the risk of injury compared to traditional float glass.

Glass Shelves and Tabletops:The enhanced strength of SIG's tempered glass makes it an excellent option for shelves and tabletops, as it can support significant weight without breaking.

Architectural Features: SIG's tempered glass can be elegantly incorporated into staircases, walkways, and balconies, providing both aesthetic appeal and safety for users.

Consumer Electronics: In the realm of electronics, SIG's tempered glass is often used for touchscreens and protective panels on devices like smartphones and tablets, offering superior scratch and impact resistance.

Our tempered glass presents a compelling alternative to standard float glass, emphasizing strength and safety. Through a precise thermal tempering process, it achieves remarkable impact resistance and predictable breakage patterns. These qualities make SIG's tempered glass an invaluable material for architects, builders, and manufacturers focused on safety and durability in their designs.
