Benefits of Heat Tempered Glass: What Does the Heat Do to the Glass?
Heat Treated Glass
Heat treating glass is done to improve its strength, as well as its resistance to cracking or shattering. Heat treated glass runs through the same furnace as tempered glass does — but it does not stay in the furnace as long.
Heat treated glass is most commonly used in applications where safety is a concern such as:
Why Choose Heat Treated Glass?
Heat treated glass and tempered glass have similar applications. However, heat treated glass is known to provide less distortion than tempered glass when looked through.
It is common for heat treated glass to be used in high end projects where the aesthetic appeal and final look of the glass is a high priority.
Due to the tension that tempered glass is under, when it breaks it breaks into many small pieces, which makes it less dangerous than standard glass. The glass entirely shatters out of the frame.
Heat treated glass is under lower tension than tempered glass as it does not stay in the furnace as long. When head treated glass breaks, it breaks into much larger pieces and the frame is able to hold the pieces in place. Because of this, heat treated glass is considered safer than other glass options.
Important note: Heat treated glass is not considered dull, and can still cause injury upon contact. However, the chance of laceration is less than with traditional annealed glass.
