TEMPERED GLASS

INTRODUCTION TO TEMPERING

Tempering is a crucial step in enhancing the strength and durability of glass, making it stronger than untreated glass of the same thickness. By subjecting glass to controlled heating and rapid cooling, internal stresses are induced, resulting in a product that can withstand greater impact and thermal stress. This process is vital in various applications, ensuring safety and reliability in diverse environments.

THE TEMPERING PROCESS

The glass is heated to a temperature close to its softening point, typically between 600 to 700 degrees Celsius (1112 to 1292 degrees Fahrenheit), within a tempering furnace. This process renders the glass malleable for shaping. As the glass enters the furnace, it oscillates back and forth to ensure uniform heating across the panel. Once adequately heated, the glass progresses down the line to the quench, where rapid cooling occurs using high-pressure air jets cooling the glass to approximately 40 degrees Celsius. This rapid cooling process solidifies the outer surface of the glass while leaving the interior in a state of tension, inducing compressive stress on the surface, and creating tensile stress within.

For safety and quality assurance, BG Glass Solutions procures tempered glass from SGCC (Safety Glazing Certification Council) certified fabricators. This ensures that the glass being produced meets all ASTM standards.
 

BENEFITS OF TEMPERED GLASS

Enhanced Strength:  Tempered glass is up to five times stronger than annealed glass, making it resistant to impact and bending forces.

 

Safety:  The break pattern of tempered glass reduces the risk of injury in case of breakage, making it suitable for applications where safety is paramount.

 

Compliance: Tempered glass meets the stringent requirements of building codes and safety standards, ensuring compliance with regulations.

In summary, the tempering process strengthens and enhances the safety of glass, making it an essential component in various applications, including windows, doors, shower enclosures, partition walls and automotive windows. Its ability to resist impact and breakage while minimizing the risk of injury makes it a preferred choice in modern construction and design.
