Heat soaked glass
What is heat soaked glass?
Heat soaking involves heating thermally toughened safety glass to 260 degrees, in accordance with BS EN 14179-1, to identify hidden nickel sulphide inclusions. These metal particles are too small to be seen by the naked eye, yet their presence can cause significant damage.
When glass is tempered at high temperatures, any nickel sulphide impurities picked up during manufacturing will change form. They then don’t have time to revert back completely at the rapid cooling stage. As such, their volume will continue to expand over time until fully cooled. Even just a small change in size can stress the glass from the inside and lead to shattering.
To avoid this, heat soak testing can be used to identify 95% of affected panes before installation. The vast majority of heat soaked glass subjected to this additional heating process will break if it contains nickel sulphide. That way, it can be detected and disposed of before it reaches our customers, avoiding breakages, saving time, money and inconvenience.
Where is heat soaked toughened glass used?
Heat soak tested glass is required for range of applications where safety standards demand high-strength glass panels. For example, glass balustrades, that while being aesthetically pleasing, are predominantly there for safety reasons. The same goes for overhead glazing, glass partitions and glass that is supporting another element.
Heat soaked glass is also ideal for intricately shaped or large panes, due to the cost and time involved in their creation. Plus, any areas where fitting a replacement would prove difficult, dangerous or disruptive. For instance, if a crane is required or you’d have to deconstruct other elements to access the glass.
