In addition to the casement type, there are many different window opening methods for the broken bridge aluminum doors and windows on the market today. Inversion and translation are the most prominent. From my personal experience, these two window opening methods do have some advantages. It saves space and has a novel opening method, but our first choice when choosing doors and windows is reliable quality and good sealing effect. , if you take a closer look at the structure and accessories of inversion and translation, you will know that dozens of accessories and screws are used to achieve inversion and translation. If there is a problem with one of the screws or accessories, the entire window sash will not work properly. After using it, I am not saying that it will definitely break, but the probability of problems is much greater than that of casement windows. Doors and windows are made with fine workmanship. Items of reliable quality are not necessary if they are too precise. Just like a mobile phone is a communication tool. You have to design it with a strong shell, and then advertise that the mobile phone can also smash walnuts. The mobile phone may not be damaged by smashing the walnuts, but the circuit board screen inside If the plug is loose in one place, the entire phone will be useless. At least for doors and windows, the simpler the design, the more durable it is, because the original intention of making doors and windows is just to prevent wind and rain, sound insulation and heat insulation, and other bells and whistles are not necessary
