WHAT IS HEAT SOAKED GLASS?

Thursday December 14, 2023

Heat soaked glass is when toughened glass is reheated and is slowly cooled. The reason for doing this is in toughened glass, there is a small risk of a nickel sulphide crystal naturally occurring in the glass during processing. The nickel sulphide crystal has a different expansion rate to glass so as glass heats and cools through the seasons, a spontaneous breakage may occur. This can be very costly if the glass is not easy to access post-installation. By heat soaking the glass, this risk is drastically reduced and if a breakage happens in the factory during processing, another panel can be produced.
