The Heat Soaked Glass process is a technique used to reduce the risk of spontaneous breakage in tempered glass. During this process, tempered glass is heated to a high temperature and held for a certain period of time, causing any defective glass to break. The remaining glass is then considered “heat soaked” and is more resistant to breakage than non-heat soaked glass.
Why Choose Hartung?
Highest Quality Tempering Furnaces
Hartung employs a fleet of world-class tempering furnaces across the enterprise. Our tempering furnaces give us the ability to produce high-quality heat-treated glass products on a consistent basis.
Our facilities and processes are carefully designed to handle the production of oversized heat-treated glass without compromising quality or durability.
Optical distortion is an inherent feature associated with heat-treated glass. Through Hartung’s commercial glass facilities, optical distortion is more effectively monitored and controlled. With cutting-edge optical distortion measurement equipment being used as a critical part of our quality control inspection process, Hartung is able to consistently put out optically flatter glass.
We have multiple shifts working around the clock to meet your schedule and your project needs. Ask your local Hartung partner about our expedited lead times for monolithic heat-treated glass products.
Key Product Features
Heat soaked glass is less likely to spontaneously break, which makes it a safer option for buildings and vehicles.
Improved Resistance Against Thermal Stress
The heat soaked glass process strengthens the glass and increases its resistance to thermal stress, which makes it more durable and longer-lasting.
Improved Resistance Against Shock
Where greater impact resistance is necessary, consider using heat-strengthened glass products. For any commercial glazing application, Hartung recommends the use of heat-treated glass. Using heat soaked glass can reduce the risk of liability for architects, builders, and property owners by reducing the risk of glass breakage.
Improved Resistance to Loads
Heat treating glass increases its resistance to wind and snow loads. This improved performance can be critical where glass is used in structurally-glazed applications.
