2. Tempered glass - Wikipedia

   en.wikipedia.org/wiki/Tempered_glass

   Using tempered glass can pose a security risk in some situations because of the tendency of the glass to shatter completely upon hard impact rather than leaving shards in the window frame. [10] The surface of tempered glass does exhibit surface waves caused by contact with flattening rollers, if it has been formed using this process.

3. Safety glass - Wikipedia

   en.wikipedia.org/wiki/Safety_glass

   Wired glass is used in the US for its fire-resistant abilities, and is well-rated to withstand both heat and hose streams. This is why wired glass exclusively is used on service elevators to prevent fire ingress to the shaft, and also why it is commonly found in institutional settings which are often well-protected and partitioned against fire.

4. List of fire-retardant materials - Wikipedia

   en.wikipedia.org/wiki/List_of_fire-retardant...

   Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat. An example of a fire-resistant material is one which is used in bunker gear worn by firefighters to protect them from the flames of a burning building.

5. Thermal shock - Wikipedia

   en.wikipedia.org/wiki/Thermal_shock

   Thermal shock resistance measures can be used for material selection in applications subject to rapid temperature changes. The maximum temperature jump, , sustainable by a material can be defined for strength-controlled models by: [4] [3] = where is the failure stress (which can be yield or fracture stress), is the coefficient of thermal expansion, is the Young's modulus, and is a constant ...

7. Architectural glass - Wikipedia

   en.wikipedia.org/wiki/Architectural_glass

   Heat-strengthened glass, or tempered glass, is glass that has been heat treated to induce surface compression, but not to the extent of causing it to "dice" on breaking in the manner of tempered glass. On breaking, heat-strengthened glass breaks into sharp pieces that are typically somewhat smaller than those found on breaking annealed glass ...
