Fully Tempered GlassFully Tempered Glass
Oldcastle GlassŪ' fully tempered glass is approximately four
times stronger than annealed glass of the same thickness and
configuration. When it is broken, tempered glass fractures into
small fragments that reduce the probability of serious injury as
compared to annealed glass. Tempered glass meets all safety
glazing standards including the federal safety glazing standard,
CPSC 16 CFR 1201. Because tempered glass fractures into many
small pieces, it tends to vacate the opening, when broken, more
than heat-strengthened and annealed glass does.
