Tempered glass, or toughened glass, has been heat-treated to make it stronger and safer to prevent injury in case if it ever breaks. In fact, tempered glass is four to five times stronger than annealed, or untreated, glass. In the event of breakage, tempered glass fractures into small, relatively harmless pieces rather than jagged shards.
Most of the glass that you see in commercial and residential spaces has been tempered. Common applications include side and rear windows in vehicles, entrance doors, shower and tub enclosures, racquetball courts, patio furniture, microwave ovens, fireplace doors and grates, and skylights. Tempered glass is also used for interior railings, display cases, office walls, and anywhere else where robust, durable glass is called for.
Glass tempering occurs following the fabrication process via the following steps.
Another way to temper glass is called chemical tempering. Rather than using a tempering oven, a post-production chemical compound is applied to the glass, causing the exchange of ions on the surface so the material compresses or flattens to create inner tension. But this method is not widely used because it is significantly more expensive.
Once the tempering process is complete, a trained glass inspector examines the sheet of tempered glass to ensure its quality before it is delivered to the customer.
More than 90 percent of the glass that Dillmeier Glass Company supplies is safety-tempered glass. As an SGCC-certified tempering company, we have perfected the process of tempering glass to meet national stringent safety requirements and quality standards, while still achieving superior turn-around times for each customer.
