Toughened or tempered glass is a type of safety glass processed by controlled thermal or
chemical treatments to increase its strength compared with normal glass.
Toughened glass is a glass produced by applying a special treatment to ordinary float
glass. The treatment involves heating a glass so that it begins to soften then rapidly
cooling it. The treatment is applied after all cutting and processing has been completed.
When the toughened glass is broken, it breaks into small pieces without sharp edges.
Toughened glass acquires a degree of strength in excess of the strength of normal glass,
sheet or plate glass, which if broken shatters into small and comparatively harmless
Toughened glass is made from annealed glass treated with a thermal tempering process.
A sheet of annealed glass is heated to above its "annealing point" of 600°C; its surfaces
are then rapidly cooled while the inner portion of the glass remains hotter.
Toughened glass also has an increased resistance to breakage as a result of stresses
caused by different temperatures within a pane.
Toughened glass is used in all forms of transport from cars to boats and ships. In all cases
(and in most countries) there are regulations in place pertaining to properties such as
strength, thickness and light transmission.
Building and Construction Industry
Toughened glass finds many applications in the building industry from internal to external.
Internally, toughened glass may be used in frameless shower screens and office partitions,
while externally it can be used for large window spans and balustrading.
Toughened glass panels can be manufactured to almost any shape, with the limiting factor
often being specific furnace dimensions (at both ends of the scale). The glass can also be
machined, with holes, bevelled edges etc.

Toughened Safety Glass
Toughened Safety Glass is a safety glass that has
increased strength and will usually shatter in small,
pieces when broken. It is used when strength, thermal
resistance and safety are important considerations.
FGI Tufglas Safety Glass is fabricated by heating
annealed glass to over 600 C and cooling it rapidly,
which locks the outer surfaces of the glass in a state of
high compression, and the core or centre of the glass in
FGI safety Glass is ideal for:
• Glass Balustrades
• Shower Screens
• Laminated Safety Mirrors
• Glass Doors and Windows
• Frameless Entry and Balustrading
• Public Venues
• Office Buildings
• Residential, Factories
• Hospitals and Schools
• Restaurants, Sporting Facilities
• Many others.
