What Is Heat Strengthened Tempered Glass
Heat strengthened tempered glass is also known as semi tempered glass and half toughened glass, it is produced by heating the glass to approximately 1,300Fo and then natural cooling but not rapidly colling it with air. The resultant glass is thermally strengthened and approximately 2 time stronger than a piece of annealed glass.


Differences Between Annealed, Tempered, and Heat-Strengthened Glass
Annealed Glass: also referred to as non-tempered and float glass. Annealed glass does not have the strength of tempered glass. When used for glass doors or windows, it is usually combined in two or three layers with a plastic interlayer to create laminated glass that has increased durability, strength, and reduced shatter danger. Annealed glass is used when an economical solution is desired.
Full Tempered Glass: tempered glass is also referred to as toughened glass, as it takes annealed glass and makes it stronger by heating it to roughly 700° Celsius (1,200° Fahrenheit) and then force-cools it at an accelerated rate, depending on the properties desired in the finished glass product. The result is glass with a higher surface compression (>10,000 psi) that is 4 to 5 times stronger to resist breakage, has less chance of thermal stress break, and when damaged, creates small fragments rather than dangerous shards.
Heat Strengthed Glass: the process of making heat-strengthened glass is similar to tempered glass, except the cooling process is slower, resulting in a lower surface compression (3,500 to 7,500 psi). This makes it roughly twice as strong as annealed glass. The breakage pattern more closely resembles annealed glass. Although it doesn’t shatter like tempered glass, it can fracture into dangerous shards. Another advantage of heat-strengthened glass over tempered glass is that there is less distortion, making it ideal when clarity is important.
