What is the difference between heat strengthened and fully tempered glass?
Heat treating glass by heat strengthening or fully tempering it increases its strength. Heat strengthened glass is approximately twice as strong as annealed glass of the same thickness, however heat strengthened glass is NOT a safety glazing product. Fully tempered glass is approximately four to five times as strong as annealed glass of the same thickness, and is a safety glazing product. When fully tempered glass breaks, it will shatter into a large number of small pieces. Solar Seal’s tempered glass complies with ANSI Z.97.1, CPSC 16 CFR-1201 and ASTM-C1048. It is important to note that heat treating glass does not change its stiffness. Glass of equal thickness will deflect equally regardless of whether or not is has been heat treated.
