Toughened Glass Explained

What is toughened glass and when do you need it? Here's a plain explanation.

What toughened glass is

Toughened glass is heat-treated so it's much stronger than ordinary glass, and if it does break it shatters into small blunt granules rather than sharp shards.

The heat treatment puts the surface under compression, which is what makes it far stronger than ordinary glass of the same thickness.

How to choose

Look for this

  • Much stronger than ordinary glass
  • Breaks into blunt granules, not shards
  • Good for impact-prone openings
  • Can't be cut after toughening
  • A true safety glass

What we'd suggest

Toughened glass suits openings where impact strength matters — large panes, doors, low-level glazing. We specify it where the opening warrants it rather than everywhere.
