Tempered glass and laminated glass is safety glass, but the laminated glass is much more security than tempered glass, because when they broke, the tempered glass will Scatter, and the laminated will stick on the interlayer. In nowadays, the people more and more care about the security, so the laminated glass is more and more popular. PVB and SGP are both laminated glass but do you know what’s the difference between them?
Both PVB laminated safety glass and SGP security laminated glass could make with a different type of raw material like clear float glass, color tinted float glass, reflective glass, low e glass, low iron glass, etc. With those different glasses and the different color interlayer, the laminated glass could meet the customized requirements like security, sound Insulation, anti-Ultraviolet, energy-saving, or decoration. So what’s the main difference between the PVB laminated glass and SGP laminated glass?
1- Name: SGP is SentryGuard Plus Interlayer, made from Dupont, PVB is Polyvinyl butyral, have many different suppliers.
2- Thickness: The PVB thickness is 0.38mm, 0.76mm, 1.14mm, multiple of 0.38mm, the SGP thickness is 0.89mm, 1.52mm, 2.28mm, etc.
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 clearer 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 doesn’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.
