Many People Have This Intuition

Many people have this intuition: the thicker the aluminum door and window profiles, the greater the sense of security; some people also believe that the higher the wind pressure resistance performance of doors and windows, the safer home doors and windows are. 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? What level of wind pressure resistance should the windows in your home have to be reasonable?

This issue must be determined based on the actual situation and cannot be generalized. Because the wind pressure resistance level of doors and windows needs to correspond to the basic urban wind pressure, it must be determined based on the standard value of wind load calculated based on different landforms, installation heights, installation location coefficients, etc. Moreover, the topographic 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 for sure. That is, the more wind pressure-resistant details on doors and windows are in place, the safer the doors and windows will be, and the sense of security will naturally increase.

1. Wind pressure resistance on doors and windows

Wind pressure resistance refers to the ability of a closed exterior (door) window to avoid damage or dysfunction under the action of wind pressure. The wind pressure resistance performance is divided into 9 levels. The higher the level, the stronger the wind pressure resistance. It is worth noting that the wind pressure resistance performance level is not the same as the typhoon level. Wind pressure resistance level 9 means that the window can withstand 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 that causes problems such as deformation and damage of doors and windows, air leakage, rainwater leakage, and wind and sand entering the house. When the pressure resistance of doors and windows is insufficient, a series of door and window safety accidents such as door and window deformation, glass breakage, hardware parts damage, and window sashes falling may occur at any time. In order to ensure the safety of doors, windows and homes, 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 profiles are linked to the wind pressure resistance of doors and windows. As far as the wall thickness of aluminum materials is concerned, according to the international standards for aluminum profiles: the minimum nominal wall thickness of aluminum profiles for doors and windows should be no less than 1.2mm, and the regular wall thickness is generally 1.4mm and above. In order to reduce the risk of our windows being blown away, when purchasing, we can ask the store what the wall thickness of the door and window products (especially windows) is. It is not recommended to purchase profiles that are too thin.

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

(2) Wind pressure resistance must not be ignored when customizing floor-to-ceiling windows. Typhoons and rainy days are common in coastal areas, and bad weather also puts high-rise floor-to-ceiling windows to the test. Be careful when designing floor-to-ceiling windows and selecting glass—that is, as the area of floor-to-ceiling windows increases, the thickness of the single piece of insulating glass must also increase accordingly, so that the glass has sufficient wind pressure resistance.

Another thing that is easy to overlook is that doors and windows also have glass pressure lines. The larger the window, the thicker and stronger the pressure line used. Otherwise, in the event of severe weather such as typhoons and rains, the window glass will not be able to support due to insufficient wind pressure resistance.

(3) You must not be negligent when it comes to the China Telecom connection! More and more people are pursuing doors and windows with large views. However, when installing doors and windows, we should also realize that the larger the size, the greater the demand for wind resistance; and the central support of doors and windows is the key to improving the overall wind pressure resistance of doors and windows. Generally speaking, windows exceeding 1.8m should use reinforced middle sills. The T connection method of the middle muntin should be connected by connectors. If only screws are used for direct T connection, it is not recommended to be used 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 openings 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, high-durability anchors are also what we need to focus on.

(4) In addition to floor-to-ceiling windows, sliding windows and outward-opening windows in your home should also be protected from wind. You can refer to these windproof designs
