General Glass Company is now producing laminated glass with SentryGlas® Structural interlayer material for storm, blast, ballistic, and single-point supported glass applications.


SGP is an abbreviation of SentryGuard Plus Interlayer, developed by Dupont for the security and hurricane glazing markets. As of June 1, 2014, Kuraray Co., Ltd. became the exclusive licensee for the technology under the trademark as SentryGlas®.

SentryGlas® is 5 times tougher, up to 100 times stiffer than EVA and PVB interlayers.

Stronger and more rigid than conventional laminating materials, SentryGlas® ionoplast interlayers help create safety glass that protects against bigger storms, larger impacts and more powerful blasts. They become an engineered component within the glass, holding more weight, so the glass can serve as a more active structural element in the building envelope, increasing framing system design freedom.
