Recently, it is reported that strong convective weather such as strong wind, lightning and heavy rainfall have appeared in many places in southern China (such as Guangdong and Jiangxi). Especially in Nanchang, Jiangxi province, it suddenly happened extreme weather such as short-term heavy precipitation, strong lightning, thunderstorm and strong wind.
The sudden severe convective weather had a serious impact on local residents. In one of the incidents, a grandmother in her 60 s and her 11-year-old grandson were resting in the room. Suddenly, they were blown out of the window by strong wind and rolled outdoors together with the window and mattress, it has attracted much attention.
Many owners of the community reported that the damage caused by strong wind was quite huge. The windows and doors of the house were blown into pieces in this severe convective weather, and the living room was even difficult to stand firm. In fact, similar events are not uncommon in our country. For example, Typhoon Hageby once sucked a resident out of the building in Yuhuan, Zhejiang province in 202020.
This incident aroused strong criticism from the social media comment area on bad merchants and fake and inferior products. Many netizens pointed out that there were a large number of inferior products in the door and window market, it has aroused widespread concern about living safety.
High-rise door and window safety
Doors and windows are an important defense line for the Guardian
At the same time, many dangerous situations and disasters and the quality and safety of doors and windows are closely related., this issue has aroused widespread concern. Severe convective weather refers to one of the disastrous weather with sudden occurrence, sharp weather changes and great destructiveness, often accompanied by thunderstorm, strong wind, short-term local heavy rainfall and other phenomena.
According to the comprehensive report of network news, in high-rise buildings impact of downstrike storm flow and narrow tube effect, land winds similar to strong typhoons are often formed in severe convective weather, instantaneous wind power can reach 11~15 levels. In this case, if the doors and windows have security risks such as design defects, substandard quality or insufficient performance, they are easily damaged and lose the protection function they should have.
The installation of glass in buildings involves facade, so safety should be considered first. However, many people tend to ignore this point. In addition to the bad weather, there may be two reasons for this situation in Nanchang.
First of all, the door and window materials of the owner's home may not be qualified. According to "technical specification for application of architectural glass" and aluminum alloy doors and windows standard, national regulations the new standard wall thickness of aluminum alloy windows shall not be less than 1.8mm.. If if the wall thickness does not meet the requirements, the aluminum alloy material will become weak, and the strength of the window to resist wind pressure will not be enough., when the wind strikes, it is easy to cause cracking and falling off.
Secondly, the installation process of doors and windows may also have problems. For example, the fixing point on each side of the window, according to the regulations, starts from the most corner, and the first screw is required at 10 to 15cm, the spacing of each screw in the middle cannot exceed 50cm. According to the principle of "narrow tube effect", when encountering severe convective weather, the outdoor wind pressure is higher than that of the Indoor , if the fixing point of the window is not stable enough, it is easy to cause the phenomenon of falling off.
How to select security doors and windows
In the face of severe convective weather, choosing high quality doors and windows becomes particularly important because it is directly related to the safety of family members. Doors and windows are not only the patron saint of home, but also a safe harbor in bad weather.

This design enables nuffite doors and windows to easily resist the challenges of various extreme weather, further enhancing the sense of security of the home.
Multiple seal design guarantee
Not only did the glass selection work hard, but also the design of heat insulation strip was carefully optimized. Insulation strip filled with polymer polyurethane Styrofoam, which not only ensures energy saving and environmental protection, but also provides better sealing and sound insulation effect.. The national standard 28mm multi-cavity insulation strip is adopted to ensure the high performance of doors and windows and make the frame more stable and reliable.
In addition, the three-in-one process is adopted, which is fully sealed and effectively waterproof and anti-seepage. Combined with the isobaric three-channel seal design, it brings users excellent indoor insulation and sound insulation experience, making your home life more comfortable and quiet.
