Definition

1. Noun:
   • A type of glass designed to reduce the risk of injury if broken: Safety glass is a composite material typically made by bonding a layer of plastic or resin between two sheets of glass. This construction prevents the glass from shattering into sharp, dangerous pieces upon impact.

Usage

• Safety glass is a mandatory safety feature in specific applications.
• It is used where there is a high risk of impact or where breakage could cause severe injury.

Examples

• Noun:
  • All windows in this vehicle are made of safety glass.
  • Building codes require the use of safety glass in shower doors and skylights.

Advanced Usage

• "Laminated safety glass": A specific type of safety glass where the interlayer is a polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA) film.

  • The car's windshield is made of laminated safety glass.

• "Tempered safety glass": Another common type of safety glass (though structurally different from laminated glass) that crumbles into small, granular chunks instead of sharp shards. It is often used for side and rear windows.

  • The side windows of the building are made of tempered safety glass.

Variants and Related Words

• Tempered glass (n): A type of safety glass processed by controlled thermal or chemical treatments to increase its strength.
• Shatterproof glass (n): A general term for glass designed to resist shattering; safety glass is a form of shatterproof glass.
