|
 A Commercial Building in Tokyo |
| TEMPALEX is a tempered glass with a compressed layer on its surface. To manufacture this product, flat glass is heated to the softening point (between 650 °C and 700 °C) and then cooled rapidly and uniformly by jets of compressed air. This special processing makes it stronger than annealed glass. | |
|
 | |
 | Strength |
| TEMPALEX has three to five times the static breaking strength of annealed glass. | |
| Thermal shock resistance |
| TEMPALEX is several times more resistant to rapid changes in temperature than is annealed glass. | |
| Safety |
| Unlike annealed glass, which can break into sharp fragments, TEMPALEX
breaks into innumerable small, cube-like fragments. |

|
Reflective images can be more deformed than those of float glass or heat reflective glass since TEMPALEX is heat processed during manufacture. |
|
TEMPALEX cannot be cut, drilled, beveled or bent after tempering. Specify accurate size and shape when ordering. |
|
For complicated shapes, submit full-size templates. |
 | |
|
Use a superior elastic sealing compound (polysulfide or silicone). |
|
Use polyethylene foam or chloroprene rubber as a backup
material. |
|
Provide setting blocks of chloroprene rubber (90° hardness) at two places along the bottom edge. |

|
The characteristics of tempered glass should be carefully considered
when determining where it will be installed. |
 |
|
TEMPALEX is not unbreakable. Be careful not to subject edges or surface of the glass to severe impact, as the glass may break completely and fall out of its frame. | |
|
Deep scratches made with a hard material may break the glass although the severity of the damage may not be evident immediately. | |
|
Strength may be decreased if the surface or edges are damaged. Handle with the same care as ordinary glass. | |
|
It is not recommended that tempered glass be used for the vision and spandrel area of a high-rise commercial building, skylights or stairwells, as glass fallout in these locations can cause human injury. In such areas, use laminated tempered glass or heat strengthened glass for the sake of safety. | |
|
Some allowable imperfections contained in all float glass may cause spontaneous breakage of installed tempered glass. | |
