Frequently Asked Questions

What is SGP interlayer?

SGP (SentryGlas®) is an ionoplast interlayer used in laminated glass. It offers higher strength, stiffness, and durability than traditional PVB, making it ideal for structural and safety applications.

How does SGP compare to PVB?

SGP has 5 times the tear strength and 100 times the hardness of PVB. It also has a higher thermoplastic temperature, better UV resistance, and lower moisture absorption.

Can SGP be used with ultra-clear glass?

Yes. R-SGP® is colorless and highly transparent, making it the perfect match for ultra-clear glass to achieve maximum clarity and aesthetics.

Is Meidi SGP certified?

Yes. Our products are certified under QMS, OHSMS, EMS, SGCC, QAI, and have passed MSDS safety certification. We hold multiple patents for production and testing equipment.

What applications use R-SGP®?

R-SGP® is used in curtain walls, skylights, balustrades, hurricane-resistant glass, blast mitigation, and high-security installations.
