Plexiglas® SB acrylic sheet bullet-resisting glazing material is a lightweight, crystal-clear, non-laminated alternative for UL-752 Class I security applications. The material offers cost savings when compared with bullet-resisting glass or polycarbonate of the same UL class rating. This version of Plexiglas® SB sheet is listed by Underwriters Laboratories as resisting medium-power small arms in both indoor and outdoor applications.

Plexiglas® SB acrylic sheet is easy to cut, drill, rout and cement using conventional tools. The cell-cast sheets are paper masked, with several UL-752 stickers strategically placed on the surface of the paper.
