Tempered Glass or Toughened Glass is made by processing normal annealed glass. The glass is subjected to heat till its softening point & then rapidly cooled in a controlled atmosphere.

Toughening process does not change the light transmission and solar prosperities of the glass. However tempered glass cannot be cut or altered. Therefore, it is made as per the requirement of the customer and all cutting, grinding, holes, cutouts, etc has to be done before the tempering process.

Limitations

• Glass cannot be cut or altered after tempering.
• The raw material used in the manufacturing of tempered glass are not free from certain defects, like Nickel Sulfide inclusions, which put tempered glass at potential risk of spontaneous breakage.
• Waviness & bending.
• Tempered glass has some roller marks and more distortion than annealed glass.
• Tempered glass as single glass should not be used for critical applications like overhead glazing where humans may walk.

• Strength
• Safety
• Edge Strength
• Resistance to thermal breakage
