better watch out!
China's first buildings to feature glass curtain walls will reach the end of their design life in the next few years, prompting experts to call for better maintenance of the structures to prevent accidents.

Glass curtain walls, in which a building's facade is made of sheet glass held in place by framework, began to appear in Chinese blueprints in 1984, and have an average design life of 25 years.

The durability of supporting parts, such as bolts and sealant, is generally 10 to 15 years.
In Shanghai, about 900 of at least 4,000 such buildings are more than 15 years old.
In Hangzhou, Zhejiang province, a 20-year-old woman was hit by shards of glass from a window that burst in a glass facade as she walked down the street on July 8. Part of her left leg had to be amputated.

A month later in Yiwu, Zhejiang province, a 20-meter-high glass ceiling in a garment market came crashing down, injuring several children, one seriously.
I wonder what the situation is in other parts of the world. Similar?
