Tempered Glass

Tempered Glass

Heat-strengthened safety glass with higher impact resistance than ordinary glass. It still looks clear, but edge stamps, hardware holes, stress patterns, and thick polished edges give clues.

Choosing points

  • Best for doors, railings, tables, and partitions where safety and strength are important.
  • Edges and holes must be processed before tempering, so hardware placement feels planned.
  • Tempered glass can show subtle roller waves or anisotropy under polarized light.
  • It is often used with clamps, patch fittings, or point supports.

How it ages

  • It resists impact better than ordinary glass, but edge damage can still trigger sudden breakage.

What to avoid

  • Do not cut, drill, or notch tempered glass after tempering; all holes and edge work must be completed before tempering.
