Safety glass is really an umbrella term for glass engineered to be less likely to break, and less likely to hurt someone when it does. The two most common types are tempered glass and laminated glass. For context, standard annealed glass shatters into long, razor-sharp shards when it breaks, which can cause severe or even fatal injuries. Safety glass gets around this through the way it’s manufactured. Tempered glass breaks into small, blunt granules instead of shards, while laminated glass bonds layers of glass to a plastic interlayer that holds everything together.
There’s also wired glass, which uses a metal mesh to keep fragments in place, though it’s fallen out of favor in modern architecture now that tempered and laminated options do the job better.
By law, safety glass is required in what’s classified as hazardous locations: sliding doors, glass near floor level, stair landings, bathroom enclosures. But beyond just meeting code, it gives real peace of mind in high-traffic spaces like schools, hospitals, and offices. Which type makes sense really depends on the threat you’re dealing with, whether that’s accidental impact, extreme weather, or someone trying to break in.
