SentryGlas® Interlayer
Structural interlayer material for storm, blast, ballistic, and single-point supported glass applications
Kuraray SentryGlas® (SG5000) is an interlayer designed to be laminated between two or multiple layers of glass. Originally developed for the hurricane glazing market, SentryGlas® can be used in applications where high performance glass is required.

SentryGlas® Interlayer Properties and Material Options
Structural Glazing– SentryGlas® structural interlayer helps architects and glazed building system manufacturers meet society’s need for greater security, energy efficiency, noise reduction, and safety requirements. It helps architects do more with less, creating innovative new spaces, while providing greater protection for occupants. SentryGlas® improves longterm weather resistance of laminated glass systems.
Safety & Security Glazing– Interlayers are used in a broad range of safety and security applications to offer protection. When designing security glass for bullet and blast resistant buildings or vehicles, SentryGlas® will help let light in and keep trouble out.
Decorative Glazing– There are many ways to decorate laminated safety glass using SentryGlas® interlayer by embedding a metal mesh or metallized PET fabric or by printing on a PVB interlayer.
Transportation– SentryGlas® interlayers help build lighter-weight, more fuel-efficient vehicles that withstand harsh climate conditions while ensuring passenger safety.
Tech Tip– SentryGlas® ionoplast interlayers help create safety glass that protects against bigger storms, larger impacts and more powerful blasts. SentryGlas® is 5 times tougher, up to 100 times stiffer than conventional laminating materials.
