It is made by glass heated up to softening point nearby,and then rapidly cooled down.

Furtures:

1.High intensity: Mechanical strength is as 1.5-2 times as annealed glass.

2.Thermal ability: Variance is as 130-170degree , which can fully withstand the impac of temperature difference on middle glass and side glass from intense solar,keeping unbroken.

3.Prevention from self destruction: Compared with tempered glass,Self Dustruction would not happen to semi-temoered glass ,which is its biggest advantage.

4.Stress residue:When it is destructed, its special structure enables fragments maintain in the frame.At the same time, every fragment remains a certain residual stress. Therefore,it still has anti-impact ability to some extent.

5.High degree of plainnesss: The degreen of plainness of temperef glass is close to annealed glass but far surpasses tempered glass.

 Application: Widely used in curtain glass wall,greenhouse,internal partition,especially suitable for compound laminated glass.
