Which type of glass contains a wire mesh embedded within its layers?

The type of glass that contains a wire mesh embedded within its layers is wired glass. This design incorporates a grid of metal wire that is embedded during the manufacturing process, enhancing the glass's structural integrity and providing increased safety. Wired glass is particularly effective in applications where additional strength is necessary, such as in doors and windows located in fire-rated walls, as it can help to contain flames and prevent the spread of fire.

Wired glass serves both a functional and safety purpose; the wire mesh helps to hold the glass together if it shatters, reducing the risk of injury from sharp glass shards. This glass type is often used in commercial buildings and industrial settings due to its durability and fire-resistant properties.
