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.

In summer, many household products need careful maintenance, otherwise it is easy to produce adverse changes in wet summer and affect the service life. The same is true of aluminum alloy doors and windows at home, which need good maintenance. I will provides 7 tips to help you maintain aluminum alloy doors and windows in summer. 1. When using aluminum alloy doors and windows, the action should be light, and the push and pull should be natural; If you find it difficult, don't pull or push hard, but eliminate the fault first. Ash accumulation and deformation are the main reasons for the difficulty of pulling aluminum alloy doors and windows. Keep the door frame clean, especially the push-pull groove. The dust accumulated in the groove and the door sealing top can be sucked with a vacuum cleaner. 2. When cleaning aluminum alloy doors and windows, people shall not step on the aluminum frame or pull the frame as support. 3. Aluminum alloy doors and windows can be dipped with soft cloth with clean water or neutral detergent. Do not use ordinary soap and washing powder, and do not use strong acid-base cleaners such as decontamination powder and toilet detergent. 4. After rainy days, wipe the wet glass and door and window frames in time, and pay special attention to wiping the accumulated water in the chute. If the chute is used for a long time and the friction force increases, you can add a little engine oil or apply a layer of wax oil. 5. The connecting parts of aluminum alloy frame shall be checked frequently, the bolts shall be tightened in time, and the damaged parts shall be replaced. The vulnerable parts of aluminum alloy doors and windows such as positioning shaft pin, wind support and ground spring shall be inspected frequently, and lubricating oil shall be added regularly to keep them clean and flexible. 6. Sealing wool and glass adhesive seal are the key structures to ensure the sealing and thermal insulation of doors and windows. If they fall off, they shall be repaired and replaced in time. 7. Frequently check the junction of aluminum alloy frame and wall. If it is loose over time, it is very easy to deform the whole frame, so that the doors and windows cannot be closed and sealed. Therefore, the screws at the connection shall be tightened immediately. If the screw footing is loose, it shall be sealed with epoxy strong glue and a small amount of cement. Kdsbuilding is a comprehensive door company integrating the development, production and sales of aluminum alloy decorative doors. The products in charge include, aluminum alloy doors, sliding doors, hanging doors, folding doors, flat doors, lattice doors, wardrobe doors, etc. the whole process adopts European manufacturing technology.

Aluminum alloy doors and windows are the connecting channel between each room and the outside world, so the installation quality of aluminum alloy doors and windows is particularly important. However, after the installation of aluminum alloy doors and windows, what points can owners refer to during acceptance to determine whether the installation meets the standard? 1. Use experience: ① Confirm whether the switch of aluminum alloy doors and windows is smooth, such as whether the switch of aluminum alloy doors and windows is smooth and whether the doors and windows will rebound or shake after locking. ② Then shake your hands back and forth to observe whether the stress of aluminum alloy doors and windows is normal, whether they are blocked or make a big noise. ③ Close the aluminum alloy doors and windows and check whether the fitting between the door leaf and the door frame is accurate and reasonable. Generally, the gap between the door leaf and the door frame should not exceed 2mm. 2. Door leaf frame inspection: The appearance inspection of aluminum alloy doors and windows includes whether there are cracks and deformation on the surface and the installation inspection of window rubber. The following are the specific operations of the inspection: ① Check the sealing strip: the contact between the sealing strip and the glass and the glass notch shall be flat without crimping and grooving. The pressure strip with sealing strip must be close to the glass. There shall be no obvious gap between the pressure strip and the profile, and the joint gap shall be less than or equal to 1mm. ② Check appearance: check whether the gloss and surface of aluminum alloy doors and windows are uneven, whether the surface is smooth, without depression and scratch, and then take a ruler to check whether the overall shape of aluminum alloy doors and windows is deformed. PS: the surface quality of aluminum alloy doors and windows directly affects the decoration effect of the whole wall after installation. Consumers are advised to check it strictly. 3. Door and window frame inspection: ① Check whether the joint between the door and window frame and the wall is tight. The edge of the door and window frame can be checked by the combination of reflector and expansion pipe. ② The installation of door and window frames directly affects the firmness of aluminum alloy doors and windows in later use, which can be checked from their firmness, flatness and tightness. ③ Check the perpendicularity range of door and window frames with a vertical measuring ruler. Generally, the allowable deviation of perpendicularity of front and side of aluminum alloy door and window frames is 2.5mm, the allowable deviation of horizontal frame is 2mm, the allowable deviation of elevation is 5mm, and the allowable deviation of vertical deviation from the center is 5mm. 4. Check the installation of door lock: ① First, check whether the installation position of door and window locks is correct and whether ...
