A citywide inspection targeting glass exteriors of all buildings has kicked off after a rash of "glass-exploding" incidents, local authorities said yesterday.
The city government will set up a public maintenance fund to help owners and management companies with expensive repair fees if their glass exteriors are found to carry potential risks.
Shen Xiaosu, deputy director of the Shanghai Construction and Transportation Commission, said they will also build a database to record all 4,000 to 5,000 glass exteriors in the city - an idea first proposed five years ago.
Although both tempered glass and dual-paned glass are considered safe as exteriors, tempered glass has a self-explosion rate of 0.3 percent over a three to five-year period, meaning that three of every 1,000 pieces could be expected to shatter.
But most developers choose to use tempered glass for its lower price - only about half the cost of dual-paned glass.
The city is planning to introduce laws about the design and maintenance of glass construction materials.
