TOUGHENED GLASS

Toughened glass is an extremely strong glass which has been thermallyheat treated to induce
comprehensive stresses of 110000-20000 psi on the surfaces and edge compression of not less than
9700 psi. Toughened glass is four times stronger than annealed glass and has enhanced thermal
resistance and impact resistance quality and breaks into small cuboid fragments rather than irregular
shards of glass and therefore is less likely to cause injury.
Toughened glass is considered to be a better substitute for alluminium, wood and other fabrication
materials. It is being used in Architectural and interior Industry for more than decades and now
dominating the annealed glass due the improvement in the mechanical properties, Glass Facades,
Structural Glass, Shower cubical, partition, slides, Steam Bath Chamber, Reflective Glazing, Shop/-
Showroom fron opening, Complete front Glazing with Spider Fittings, Frameless Sliding/Swing Doors,
Stairs Step, Railukubgm Escalator Side Panels, Glass Canopy, Solar Refrigeration, Lighting and other
industrial usages, automative Industries, Furniture and Interios, Appliances Industries, Railway,
roadways and Airport, Display Boxes, Rack Banners, Squash Court Wall, Partitions, Cabins And many
more examples where Toughened glass is used.
ADVANTAGES OF TOUGHENED GLASS
• 4-5 times stronger than its equivalent thickness of normal annealed glass of same thickness
o
• Temerature resistance upto 250 C
• Very difficult to break, but incase of breakage due to heavy impact or thermal shock, it will break into
small pieces (prills) without any sharp edges as compare to normal annealed glass
o
• Resistance to the rapid temperature change and can withstand changes of 150 C without breaking
