What is tempered glass?
Tempered glass is a type of glass that undergoes a special heat treatment process, making it stronger and more impact-resistant. When broken, it shatters into small granules instead of sharp shards, enhancing safety.
How is tempered glass made?
Tempered glass is made by heating regular glass to near its softening point (around 620°C), followed by rapid, uniform cooling (quenching). This process creates compressive stress on the surface and tensile stress inside, enhancing its strength.
Can tempered glass be reprocessed?
No. Once tempered, the glass cannot be cut, drilled, or polished, as it will shatter. All processing must be done before tempering.
Applications of tempered glass in construction?
It’s widely used in curtain walls, doors/windows, glass railings, shower enclosures, and partitions due to its safety and wind resistance, meeting construction standards.
Does tempered glass reduce noise?
Tempered glass alone isn’t designed for noise reduction, but combining it with laminated (e.g., PVB) or insulated glass can improve soundproofing.
Does tempered glass spontaneously break? Prevention?
Rare spontaneous breakage may occur due to impurities (e.g., nickel sulfide). Using high-quality glass and "Heat Soak Test" can minimize risks.
Temperature resistance range?
It withstands -40°C to +300°C, but sudden localized heating/cooling may cause breakage.
What is the lifespan of tempered glass?
Theoretically permanent if undamaged, but inspect for aging after 10-15 years in practice.
