1. Tempered heat soaked glass cannot be cut, pierced, and chipped off after the production. Thus, measuring areas carefully is necessary, and we encourage to use the unit of 'millimeter' for an accuracy. Allowing it to be slightly loose will enable to install glass easier, yet it shouldn't be too loose to slip out of glass moldings.
2. A single piece of tempered heat soaked glass should not be used for making a roof or a wall of high-rise buildings as it is possible to fall over in case glass is broken.
3. A single piece of tempered heat soaked glass should not be applied for floor making, pedestrian areas, or staircase as people can fall down immediately when the glass is broken, and it can harm people down there as well.
4. Tempered heat soaked glass cannot be used as a substitution for fire-proof glass since tempered glass cannot resist fire and provide safety for residents according to the restriction of fire-proof.
The means to testify Tempered Heat Soaked Glass
It impossible to examine whether glass is tempered heat soaked glass or not. The detection by using polaroid film can only indicate that the glass had been under heat treating process. Breaking glass or using special instrument (Laser GASP) can only disclose how much tension that particular glass contains and prove whether it is a tempered glass or not. Only information provided by the factory can indicate the use of heat soaking procedure; hence, the factory guarantees the breakage of heat soaked glass by substituting a new one in case of spontaneous glass breakage is detected. (Despite the fact that there is still risk of self breakage, the factory is willing to take responsibility over that risk.)
Notice: If tempered glass of any projects has a large number of glass breakage in tempered glass, it signifies that those tempered glass are not tempered heat soaked glass.
