Architectural glass is glass that is used as a building material. It is most typically used as transparent glazing material in the building envelope, including windows in the external walls. Glass is also used for internal partitions and as an architectural feature.
Fully tempered glass is approximately four times stronger than annealed glass of the same thickness and configuration, and residual surface compression must be over 10,000 PSI for 6mm, according to ASTM C 1048. When it breaks, it will break into many relatively small fragments, which are less likely to cause serious injury.
Tempered glass is often referred to as “safety glass” because it meets the requirements of the various code organizations that set standards for safety glass. This type of glass is intended for general glazing, and safety glazing such as sliding doors, storm doors, building entrances, bath and shower enclosures, interior partitions and other uses requiring superior strength and safety properties. Tempered glass cannot be cut or drilled after tempering, and any alterations, such as edge-grinding, sandblasting or acid-etching, can cause premature failure.
Features and Benefits
- Improves mechanical, tensile and thermal strength by 4 to 5 time over annealed glass.
- Reduces thermal breakage due to edge strength being better and thermal endurance higher.
- Provides safety since the glass break into very small piece with dulled or blunt edges.
