Tempered Glass

TEMPERED GLASS

Tempered for Strength. Trusted for Safety.

Tempered glass (also known as toughened glass) is an extremely strong glass which has been thermally heat treated to induce compressive stresses of 10,000 to 20,000 psi on the surfaces and edge compression of not less than 9700 psi.

Tempered glass is being used increasingly in architecture because of its strength and safety properties. It is usually installed in areas where safety glass is required to reduce the possibility of mechanical or thermal breakage and/or to assure greater uniform load strength. Worldwide the use of Tempered glass or Safety glass in general has been mandated by building codes. These Codes are also made for India and are in the process of being mandated.

Cut to size glass are electrically heated in the furnace where it oscillates back and forth on rollers till glass reaches temperature of about 650°C. After heating, the glass is conveyed to a quenching chamber where it is cooled rapidly by a blast of air, blown through nozzles, on both sides of glass.

CHARACTERISTICS OF TEMPERED GLASS

PRODUCTION PROCESS

At Masss Glass India, we offer end-to-end glass processing services tailored to meet architectural, industrial, and custom design requirements. Our facility is equipped with advanced machinery and skilled technicians to ensure precision, safety, and consistent quality in every stage of glass preparation.

Our Core Processing Capabilities

✅ Cutting: Precision cutting for float, laminated, and specialty glass to exact dimensions and complex shapes.
✅ Grinding: Smooth edge finishes using high-speed edging machines for safety and visual clarity.
✅ Drilling: Accurate hole drilling for fittings, handles, and architectural elements with minimal stress.
✅ Fabrication Works: Complete customization, from edge profiles to slots, notches, and hardware-ready designs.
✅ Washing: Automated, streak-free washing systems ensure crystal-clear clarity and dust-free surfaces before final treatments.

STRENGTH

Toughened (or Tempered Glass) is four to five times stronger than its equivalent thickness of normal annealed float or sheet glass.

Benefits of Toughened (Tempered) Glass

✅ High Strength: Up to 4–5 times stronger than standard annealed glass, making it highly impact-resistant.
✅ Safety First: Breaks into small, blunt fragments instead of sharp shards, reducing risk of injury.
✅ Thermal Resistance: Can withstand sudden temperature changes up to 250°C — ideal for both indoor and outdoor applications.
✅ Durability: Resistant to mechanical stress, bending, and high wind loads — perfect for facades, partitions, and railings.
✅ Enhanced Security: Offers increased resistance to forced entry or vandalism compared to regular glass.

HIGH THERMAL SHOCK STRENGTH

Tempered Glass provides greater thermal strength. It offers increased resistance to both sudden temperature change and temperature differentials up to 240°C compared to normal annealed glass, which can withstand temperature differentials up to 40°C only.

Thermal Performance Benefits of Tempered Glass

✅ High Thermal Strength: Withstands temperature differentials up to 240°C, far beyond the 40°C limit of annealed glass.
✅ Resistant to Thermal Shock: Ideal for environments with sudden temperature changes, such as kitchens, facades, and glazing near heat sources.
✅ Safe for Solar & Industrial Use: Suitable for areas exposed to direct sunlight, heated appliances, or machinery.
✅ Reliable in Harsh Weather: Performs consistently in cold climates or hot, sunny regions with wide daily temperature swings.

SAFETY

Tempered Glass is very difficult to break. Even on breakage, it will break into small, relatively harmless fragments. This substantially reduces the likelihood of injury to people as there are no jagged edges or sharp corners, which are normal in the case of breakage of annealed glass.

Safety Benefits of Tempered Glass

✅ Shatter-Safe Design: Breaks into small, blunt fragments that reduce the risk of cuts or serious injury.
✅ No Sharp Edges: Unlike annealed glass, tempered glass doesn’t form dangerous jagged shards on breakage.
✅ Peace of Mind: Provides a safer environment for homes, offices, public buildings, and transport systems.
✅ Mandatory in Critical Zones: Required by building codes in areas like staircases, balconies, glass doors, and shower enclosures.
