Toughened Glass
Firman Glass manufactures a comprehensive range of toughened glass products
under the industry recognised 
banner to cover a multitude
of end uses from Architectural, through to retail and domestic to a maximum
size of 3000mm wide x 5000mm long and up to 19mm thick in its monolithic form.
The base product for toughened
glass is annealed soda-lime silica glass. The raw material is subjected to
a heat treatment process, which induces a compressive stress to the surfaces
of the glass panel. This increase in compressive stress increases the resistance
to mechanical forces. Generally, toughened glass is five times stronger than
the same thickness of annealed glass which when fractured breaks The balanced
internal stresses created during this heating process causes the glass to shatter
into small, granular chunks instead of the more dangerous jagged shards of
non toughened glass.
