Every Merlord door uses tempered safety glass that meets the ANSI Z97.1 standard. Here is what that actually means for your home.

Tempered glass is heat-treated so the outer surfaces are in compression and the core in tension. That makes it several times stronger than ordinary glass, and if it ever does break, it crumbles into small, blunt pieces instead of sharp shards — much safer in a bathroom.
