Core Viewpoint - The article discusses the increasing incidents of glass breakage due to extreme high temperatures, particularly in regions like Henan and Shaanxi, where temperatures have exceeded 40°C. It highlights the causes, conditions, and preventive measures related to glass breakage during high-temperature weather. Group 1: Causes of Glass Breakage - High temperatures lead to a significant increase in glass self-explosions, with reports indicating that a glass installer has replaced an average of one glass panel per day recently [9] - Temperatures inside and outside can create a thermal expansion effect, causing glass to crack, especially when the temperature difference is large [11] - The presence of nickel sulfide in tempered glass can expand under heat, leading to structural failure when it expands by 20%-40% [11] Group 2: Conditions Leading to Breakage - Glass breakage is more likely to occur after high temperatures followed by heavy rain, or when air conditioning creates a large temperature difference [13] - Older glass is more susceptible to breakage due to increased brittleness from prolonged exposure to the elements [15] - Larger glass surfaces, such as floor-to-ceiling windows, are at a higher risk of breaking [16] - Single-layer glass is more prone to breakage compared to double-layer vacuum tempered glass under high temperatures [17] Group 3: Prevention Measures - Glass should not be installed too tightly in metal frames to avoid breakage due to thermal expansion [19] - It is advisable to keep indoor air conditioning temperatures above 26°C to minimize temperature differences [20] - Regular inspections of windows and glass facades are essential to identify and address any signs of wear or damage [21] Group 4: Legal and Safety Considerations - High temperatures can lead to property damage and safety hazards, with developers typically offering a two-year warranty on glass installations [23] - Homeowners can seek third-party assessments to determine if glass breakage was due to self-explosion, which may hold developers accountable for repairs [24] - In case of injury from broken glass, immediate first aid is crucial, and medical attention should be sought if necessary [27]
