Which of the following types of glass is often used in fire doors and windows designed to prevent fire spread?

Wired glass is specifically designed for fire safety and is commonly used in fire doors and windows aimed at preventing the spread of fire. The inclusion of wire mesh within the glass provides structural integrity, allowing it to withstand high temperatures and resist breaking during a fire. This makes wired glass particularly effective in maintaining barriers between fire zones and non-fire zones, helping to slow or prevent the progression of flames and smoke.

In contrast, tempered glass, while stronger than regular glass, can shatter under extreme heat and is not specifically rated for fire resistance. Laminated glass consists of layers of glass and interlayer materials for sound reduction and safety but does not inherently possess fire-resistant properties. Double-paned glass primarily functions for insulation and does not provide adequate fire resistance or structural support in a fire scenario. Each of these alternatives lacks the fire-specific attributes that wired glass offers, making wired glass the appropriate choice in scenarios requiring fire safety.
