Heat-soaked glass is an upgraded safety variant of tempered glass. Through constant-temperature soaking at 280°C, potential nickel sulfide inclusions are forced to undergo phase transformation and fracture in advance, significantly reducing the probability of spontaneous breakage later. After heat soaking, the spontaneous breakage rate of tempered glass drops from an industry average of 3‰ to below 1‰, meaning high-rise curtain walls, large glass canopies, and balustrades in densely populated areas can largely avoid sudden safety hazards and costly replacement expenses from spontaneous rupture.

Our heat-soak furnace employs a high-convection circulation system with large chamber volume and uniform temperature control, capable of batch-processing oversized lites without local temperature differences. Each cycle features real-time temperature-curve recording and precise constant-temperature timing to ensure every lite undergoes a complete soaking period, strictly complying with EN 14179-1. For overseas projects demanding ultimate safety, low maintenance, and long-term warranty, heat-soaked glass is the smart procurement choice for reducing operational risks and enhancing building quality.
