DuPont Glass Laminating Solutions has published new online information about laminated safety glass that has been tested to meet international bullet-resistant glazing test standards, according to a Nov. 20 release. A new technical bulletin describes laminated glass constructions made with DuPont SentryGlas, Spallshield and Butacite laminating materials, helping glass manufacturers achieve bullet resistance using alternatives to traditional all-glass or glass-clad polycarbonate designs.

Test standards referenced in the bulletin include: Underwriter's Laboratories Standard 752, Standard for Bullet Resisting Equipment; National Institute of Justice -- NIJ 0108.01, Ballistic Resistant Protective Materials; and Europe’s EN 1063, Glass in Building. Tables are presented showing threat levels defined in each standard, along with designs, including glass thicknesses, that have been laminated and successfully tested to meet the standards. 

"Combining advanced interlayers in new bullet-resistant safety glass designs can often result in test-compliant laminates that are thinner, lighter weight, clearer and more durable than previously available," said Ivan Escalante, global BRG market leader for DuPont Glass Laminating Solutions, in the release.

The new publication, "Technical Bulletin: Ballistics-Resistant Glazing Compositions," is available for download.
