Heat-treated glass is glass
manufactured by treating float glass with heat-strengthen process.
Strength of heat-treated glass
is roughly twice of float glass.
Heat-treated glass has
increased resistance to impact, mechanical loads and thermal stress
breakage as compared to regular float glass.
Manufacturing Process
- Float glass is heated
to 1150ºC with tempering oven and then rapidly cooled with
high-pressured air.
- Float glass is
transformed into heat-strengthened glass after the tempering
process.
Characteristics
- All properties remain unchanged as compare to float glass
except for its strength and breaking pattern.
- Due to higher amount of residual stress, Heat-strengthened
glass breaks into smaller pieces than that of float glass when
broken.
Thermal shock resistance
- Temperature differential of 121ºC
to fracture a sheet of
¼” heat-treated glass.
Where to use heat-treated glass?
- Patio and Storm Doors
- Entrance and Sidelites
- Tub and Shower Enclosures
- Windows: Commercial / Residential, Fixed and Operable
- Displays
- Partitions
- Shopfronts
- Handrails
