Heat Strengthened Glass

Balancing strength and thermal stability, Heat Strengthened Glass offers enhanced performance over annealed glass while maintaining controlled breakage behaviour for architectural reliability.

Product Details

Heat Strengthened Glass undergoes a controlled heating and cooling process that increases its strength and thermal resistance without fully tempering it. Unlike fully tempered glass, it cracks into larger fragments, making it suitable for laminated safety applications.

It is widely used where strength, heat resistance, and predictable breakage are essential.

Benefits & Applications
  • Increased Strength: Stronger than annealed glass
  • Thermal Resistance: Handles moderate temperature variations
  • Controlled Breakage: Ideal for laminated assemblies
  • Reduced Optical Distortion: Uniform surface quality
  • Design Compatibility: Works well in large panels
  • Curtain walls & facades
  • Spandrel panels
  • Laminated safety glass systems
  • Commercial buildings
  • Structural glazing applications
  • Type: Heat Strengthened Architectural Glass
  • Thickness Range: 6 mm to 19 mm
  • Strength: ~2x stronger than annealed glass
  • Thermal Resistance: Higher than normal glass
  • Breakage Pattern: Large fragments
  • Compliance: As per applicable IS / international standards
  • Customisation: Size, tint, edge finish, lamination
  • Standard: EN – 1863 – 1
