How safe is a glass shower door or enclosure?
• A. All glass doors and enclosures are specified by code to be tempered glass. Glass is tempered by applying heat, which strengthens the glass. When untempered glass is shattered, it breaks into large, dangerous shards. Tempered glass, on the other hand, is much stronger than untempered glass and, if it is broken, breaks harmlessly into many tiny beads of glass.
