Heat Soaked Glass
From furniture to glass partitions, toughened glass is a legal requirement for most interior applications. But did you know that there’s still a small chance of it shattering due to impurities in the glass? While not entirely preventable, heat soaking the glass greatly reduces this risk. As such, if you’ve included glass installations in your latest project, we’d recommend upgrading to heat soaked glass. Learn more about the process and its benefits for your clients below.

What is heat soaked glass?
Heat soaking involves heating toughened safety glass to 260 degrees, in accordance with EN 14179-1, to check for 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 soaking 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 your customer’s site, saving time, money and inconvenience.
Where is heat soaked toughened glass used?
Heat soak tested glass is useful for range of applications where architectural designs rely on sturdy, high-strength panels. For example, glass balustrades, that while being aesthetically pleasing, are predominantly there for safety reasons. The same goes for overhead glazing and glass that is supporting another element.
Heat soak 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 tricky. For instance, if a crane is required or you’d have to deconstruct another element to access it.
