laminated glass
Học thuậtThân thiện
Definition
Noun: - A type of safety glass: Laminated glass is a composite material consisting of two or more sheets of glass bonded together with one or more interlayers of plastic (such as polyvinyl butyral or PVB) or resin. This construction prevents the glass from shattering into dangerous shards upon impact, as the interlayer holds the broken pieces together.
Usage
- Laminated glass is primarily used for safety and security in applications where broken glass could cause injury or where additional protection is needed.
- It is commonly found in automobile windshields, skylights, glass railings, and windows in hurricane-prone areas or for sound reduction.
Examples
Advanced Usage
- "Acoustic laminated glass": A specific type that includes special interlayers designed to dampen sound, used in buildings near airports or busy streets.
- "Security laminated glass": Laminated glass with multiple thick glass plies and interlayers to resist forced entry, used in banks and storefronts.
Variants and Related Words
- Safety glass: A broader category that includes both laminated glass and tempered glass. Laminated glass is one type of safety glass.
- Tempered glass: Another type of safety glass that is treated by heat or chemicals to increase its strength. Unlike laminated glass, tempered glass shatters into small, granular chunks instead of sharp pieces.
- Interlayer: The plastic (often PVB) or resin layer that bonds the glass sheets in laminated glass.
Synonyms
- Safety glazing
- Composite glass
- Shatterproof glass (Note: This is a common informal term, though technically the glass can still crack; it is the shards that are held together.)
Related Phrases and Concepts
- "Glass laminate": Another way to refer to the laminated glass product or the process of creating it.
- "PVB interlayer": Refers specifically to the polyvinyl butyral material commonly used as the bonding layer in laminated glass.
Noun
- glass made with plates of plastic or resin or other material between two sheets of glass to prevent shattering
