What Kind of Doors And Windows Can Withstand Category 17 Typhoons?

The typhoon hit the coastal areas of Hainan, and many people's doors, windows, and balconies were blown away... Its power and degree of damage once again reminded people of the importance of door and window safety.

Many people have this intuition: the thicker the aluminum door and window profile, the more secure it is; some people also think: the higher the wind pressure resistance of doors and windows, the safer the home doors and windows. There is nothing wrong with this view in itself, but it is not entirely reasonable. So the question is: how to improve the wind pressure resistance of doors and windows? How many levels of wind pressure resistance should the windows at home reach to be reasonable.

For this question, I want to say: it depends on the actual situation and cannot be generalized. Because the wind pressure resistance level of doors and windows needs to correspond to the basic wind pressure of the city, it must be determined by calculating the standard value of wind load based on different landforms, installation heights, installation position coefficients, etc. Moreover, the terrain environment and climate environment of major cities in China are different, so the wind pressure resistance level of doors and windows cannot be the same answer. However, one thing is certain. That is, the more complete the wind pressure resistance details on the doors and windows, the safer the doors and windows, and the sense of security will naturally rise.

1. Wind pressure resistance of doors and windows

Wind pressure resistance refers to the ability of closed exterior (doors) and windows to avoid damage and functional impairment under wind pressure. Wind pressure resistance is divided into 9 levels, and the higher the level, the stronger the wind pressure resistance. It is worth noting that the wind pressure resistance level is not equivalent to the typhoon level. Wind pressure resistance level 9 means that the window can withstand a wind pressure of more than 5000pa, but it cannot simply correspond to the same typhoon level.

2. How to improve the wind pressure resistance of the entire window?

Wind is the culprit for deformation, damage, air leakage, rainwater leakage, and wind and sand entering the house of doors and windows. When the pressure resistance of doors and windows is insufficient, a series of door and window safety accidents such as deformation, glass shattering, hardware parts damage, and window sash falling may occur at any time. In order to ensure the safety of doors, windows and homes, the customization of doors and windows in areas prone to typhoons and strong winds should focus on improving wind pressure resistance.

(1) Generally speaking, the thickness, hardness, corrosion resistance and oxidation resistance of the profile are all linked to the wind pressure resistance of doors and windows. As for the wall thickness of aluminum materials, according to the international standard for aluminum profiles: the minimum nominal wall thickness of aluminum profiles for doors and windows should not be less than 1.2mm, and the regular wall thickness is generally 1.4mm or above. In order to reduce the risk of your windows being blown away,

(2) In addition, you should also pay attention to the hardness of aluminum profiles for doors and windows. Take 6063 aluminum, which is widely used in building aluminum doors and windows and curtain wall frames, as an example: the national standard stipulates that the hardness of 6063 aluminum profiles should be greater than 8HW (Webster hardness tester test). This will better withstand strong winds and typhoon weather.

(3) When customizing floor-to-ceiling windows, you must not ignore wind pressure resistance. Typhoons and rainstorms are frequent in coastal areas, and bad weather also puts a great test on high-rise floor-to-ceiling windows. Be careful when designing floor-to-ceiling windows and choosing glass - that is, as the area of floor-to-ceiling windows increases, the thickness of single-piece insulating glass should also be increased accordingly to ensure that the glass has sufficient wind pressure resistance.

Another point that is easy to overlook is that doors and windows also have glass pressure lines. The larger the window area, the thicker and stronger the pressure line should be. Otherwise, when encountering typhoons, rainstorms and other bad weather, the window glass will not be able to support due to insufficient wind pressure.

(3) The center support connection must not be neglected! More and more people are pursuing doors and windows with large views. However, when installing large doors and windows, we should also realize that the larger the size, the greater the demand for wind resistance; and the center support of doors and windows is the key to improving the overall wind pressure resistance of doors and windows. Generally speaking, windows over 1.8m should use reinforced center bars. The center bar T connection method should be connected with connectors. If only screws are used for direct T connection, it is not recommended to use it in coastal typhoon areas or high-rise windy areas.

In addition to the strength of the doors and windows themselves, the installation stability of the doors and windows in the opening also plays a vital role in the safety of the doors and windows. Reasonable installation methods, strictly controlled installation processes, and the selection of high-quality and durable anchors are also the focus of our attention.

(4) In addition to floor-to-ceiling windows, the sliding windows and outward-opening windows in the home should also pay attention to wind protection. These windproof designs can be used as reference.
