Security glass or Safety Glass is a broad category of fortified glass that is used to help resist breakage when encountering projectiles, natural disasters, and even explosions. They consist of laminated glass systems, meaning that two or more sheets of glass are permanently bonded together by an interlayer (see Laminated Glass products page for a more detailed product description). By modifying the heat-treatment of the glass, the number of panes and the interlayer material, various levels of strength and resistance can be achieved.

Laminated glass products are being used in various types of building construction applications serving as durable, translucent fenestration and building interior material options that offer the benefits of daylighting and unobstructed views while also meeting building code standard requirements for safety glazing applications.

Laminated glass is constructed by permanently bonding two or more lites of glass together with a polymeric interlayer sheet using a process that involves exposure to cycles of heat and pressure within a specialized autoclave chamber. The interlayers secure the glass to create a strong, uniformed layer even when broken. Laminated glass comes in a variety of thicknesses and different glass combinations, interlayer components or coatings.
