3- Strength: The SGP laminated glass is five times stronger and up to 100 times stiffer than PVB laminated glass.
4- Safety: The SGP laminated glass is stand up when broken, while the PVB laminated glass is fell down.
5- Clarity: The SGP yellow index is smaller than 1.5, while the PVB yellow index is 6-12, so the SGP laminated glass is much more clear than PVB laminated glass.
6- Application: With the high security performance, the SGP is widely used to against the severe weather like storms, hurricane and cyclone, and it don’t need frame while use as balustrades. But for PVB laminated glass, if use them to against the bad weather, it is easy to delaminate.
