Toughened glass is now required by regulation for every building project due to its increased strength and safety characteristics.
When all proprietary operations are completed from drilling, notching, edgework including any printing if required, the glass is passed through our oscillating furnace and heated to around 630 C. Once the heating process is completed, the glass is transferred to the quenching chamber where it is rapidly cooled. The structure of the glass is then transformed creating very high permanent surface compressive stress. In conclusion, if the glass is broken the contained stress is released and results in the glass breaking into small harmless particles. The glass also becomes stable against thermal fracture caused by partial shading once in situ.
