Normally, aluminum alloy doors and windows will not leak water and air, but recently, friends in Jiangsu and Zhejiang affected by super typhoon said that when the typhoon passes through, a lot of rain has accumulated in the door and window joints at home, which is very troublesome to clean. In fact, the aluminum alloy doors and windows with qualified quality can achieve the effect of tight fit after installation. If there is water in every wind and rain, it may be that the aluminum alloy doors and windows are not selected properly. For the purchase of aluminum alloy doors and windows, kdsbuilding summarized several purchase skills. If you need it, remember to collect it!
1. The materials are required by the national standard
In fact, many home decoration materials have very strict national standards, and aluminum alloy doors and windows are no exception. According to national regulations, the wall thickness of aluminum profile of aluminum alloy doors and windows should be more than 1.6mm, and the thickness of oxide film should also be 10 microns. These factors determine its pressure bearing capacity. High quality aluminum alloy doors and windows will not shake and loosen even in the face of typhoon, which is safe and worry-free.
2. Try to choose double glass
Glass is one of the soul materials of doors and windows. When purchasing, if it is not used indoors, but used in a street room or balcony, it is recommended to choose double-layer glass as far as possible. The middle of aluminum alloy doors and windows with double-layer glass will be filled with inert gases, such as argon and nitrogen, which can not only insulate and keep warm, but also isolate external noise to a greater extent and give families a quieter sleeping environment.
3. Pay attention to the splicing at the corner
When purchasing aluminum alloy doors and windows, it is easy to miss the inspection of sealing. Many people will check the smoothness of glass, surface aluminum and push-pull when selecting and completing, but ignore its water tightness. As a result, in case of wind and rain in the future, the notch will be full of ponding, which is very troublesome to clean. Therefore, when purchasing, you should pay attention to whether the sealing strip of doors and windows and the contact between glass and notch are flat, and refuse the doors and windows with crimping and grooving, so that there will be no shaking feeling when the wind blows, and the water tightness is better, which can truly prevent wind and rain.
