Tempered Laminated glass breakage pattern

Can somebody give a detailed description of breakage pattern of Laminated (sentry glas plus) Tempered glass. What possible reason would be if a tempered laminated glass breaks (only inner glass) after 20days of installation? Does it prove the tempering quality alone? What should the breakage pattern be if so?

The only Laminated-Tempered glass I have come across was used in a conservatory roof. The outside pane was tempered for debris and thermal shock resistance, and inside pane was raw glass laminated to the tempered glass so that if the tempered glass shattered the whole pane stayed in place in the roof panel. The break pattern of the tempered glass, if it had shattered, would have looked like a normal tempered glass break pattern (i.e. more than 40 particles in a 5cm x 5cm square)

The origin of the break pattern will tell you why it failed. If the origin of the pattern is away from the edges of the glass you should see two ears and in between the two ears you may be able to see a very small black speck. If so, it was probably a nickel sulphide particle that cause the failure. If the break appears to originate from an edge it would be due to bad edgework, or a handling chip or possibly something in the frame that chipped the glass during expansion and contraction due to sunlight.
The beauty of a laminated tempered glass breaking is that you have all the pieces intact to analyse what caused it.

1. The mechanical strength of tempered glass redoubled 4-5 times strength than ordinary annealed glass.
2. Breakage hurts reduced: When breakage occurs, the tempered glass disintegrates into countless even small obtuse fragments, which reduces its hurts to human body.
3. It can with stand a very wide range of rapid temperature changing with the endurance of 200-300 Celsius degree.
No tong marks on the glass as TC adopts the horizontally tempering process.
5 times harder than ordinary annealed glass.
Once breakage occurs, the glass disintegrates into small cubical fragments which are relatively harmless to human body.

We are a factory producing tempered glass, laminated glass, solar glass, reflective glass, float glass, sheet glass ,and electric appliance glass including TV-stand glass, fridge glass etc. of good quality and low price.
Should any of the items be of interest to you, please contact us.
