PVB Laminated Glass vs SGP Laminated Glass

PVB laminated glass is made by sandwiching a layer of polyvinyl butyral (PVB) between two layers of glass, while SGP laminated glass is made using a layer of SentryGlas® Plus (SGP) instead of PVB.

Differences:

• PVB laminated glass has more elasticity and is better for sound insulation, while SGP laminated glass is stiffer and stronger.
• PVB laminated glass can be more easily bent or curved, while SGP laminated glass is better suited for structural applications.
• SGP laminated glass has higher resistance to impact and better retention of structural integrity after breakage compared to PVB laminated glass.

Conclusion:

Both PVB and SGP laminated glasses have their own advantages and are suitable for different applications. The choice between the two should be made based on the specific requirements of the project.

FAQs:

Q: Which is better for safety and security?

A: SGP laminated glass is better for safety and security due to its higher impact resistance and retention of structural integrity after breakage.

Q: Can PVB laminated glass be used for structural purposes?

A: While PVB laminated glass can be used for some structural applications, SGP laminated glass is generally preferred for its superior strength and stiffness.
