10+10+10 Triple SGP Laminated Oversized Glass Good Quality
SGP laminated oversized glass is composed of at least two panes of tempered glass by SGP film. It has a much higher thermal shock resistance than float laminated glass.
When the pane breaks, the small fragments with blunt edges generally remain stuck to the SGP film. It is difficult to pierce the film, which considerably reduce the risk of injury.
Early laminated glass was generally produced by PVB film. PVB film was originally developed for automotive glass rather than for the building curtain wall industry. Although PVB film has been widely used for many years in the construction industry and gets good performance, it is not suitable for high-performance glass curtain walls due to the features of PVB film as follows:
Flexibility, softness and small shear modulus
The two glass sheets will have relative slip after being stressed and then it makes less load capacity and larger bending deformation
The SGP (SentryGlas® interlayer) is 5 times stronger and up to 100 times stiffer than PVB films. Besides its strength, SGP retains its clarity – even after years of service.

Heat Soaked Testing
A rare but nonetheless undesirable property of tempered glass is spontaneous breakage: tiny inclusions of nickel sulfide, invisible to the naked eye, expand in volume over time, and can cause the pane to break unexpectedly even years after installation. One reliable means of detecting nickel sulfide inclusions is the heat soaked test, in which the panes are warmed to about 290℃. During a soak time of about four hours in the heat soak oven, the tempered glass panes will nickel sulfide inclusion will probably break and hence never be installed in the first place.
