Will the glass crack at MINUS 20 degrees?

The window glass may be frozen and cracked at MINUS 12 degrees. Glass is a poor conductor and fragile. When the temperature difference between the inside and outside of the glass is too large, its internal and external expansion leads to inconsistency and it will burst.

In the environment of MINUS 12 degrees, if the temperature difference between indoor and outdoor is too large, the glass will freeze and crack. If the glass at home is cracked by freezing, don't handle it yourself. Contact the manufacturer to replace the glass.

Case:

Ms. Zhuang, a citizen, told the column of "Zero Distance between Government and People" of the Northern Network that she is the owner of Hua Ting in Dongli District. The community delivered the house in the summer of 2020 and moved in more than one month after renovation. Some time ago, in the cold wave weather, the glass of Ms. Zhuang's house was frozen and cracked. It is understood that the glass of other owners' homes in the community has also been frozen and cracked.

On the afternoon of 65438+ 10 18, the reporter came to Hua Ting Community, Li Shang, Dongli District, and found that the glass of the owner's house was double-layer vacuum glass, and the cracks appeared vertically. Subsequently, the reporter came to the residential property company to understand the situation. A staff member said that these houses are still under warranty, and the maintenance work is undertaken by Li Bin Real Estate Company.

The reporter went to the first maintenance department of Li Bin Company near the community, but the door was locked and there was no one inside. The contact number is posted on the door. The reporter dialed the telephone number of the scene. A person in charge of window maintenance of the company said that the cracks in the glass were mainly caused by the large indoor and outdoor temperature difference in the cold wave weather some time ago. They counted the number of families with broken glass.

As the glass factory has been on holiday, they will carry out maintenance after the Spring Festival. At present, the cracks on the glass will not expand basically, and even if they do, there will be no horizontal stripes. The glass is sealed up and down and won't break.
