The products produced by unqualified door and window aluminium machine
have many disadvantages. It not only means that the quality of the door and window may be relatively poor, but it will actually affect people's daily life. For example, a series of daily heat preservation and sound insulation problems. 1. Unqualified doors and windows that affect daily use are worse than qualified products in terms of glass and hardware accessories. At the same time, after long-term use, the key connection position and other parts are easily damaged and oxidized. In the worst case, the doors and windows cannot be opened normally; in the worst case, it is easy to cause the doors and windows to fall off. Just imagine, if you live on a high floor, you really can’t guess! 2. Huge potential safety hazards Nowadays, children fall from buildings and windows and doors fall off from time to time. The reason is mostly that the quality of doors and windows is not closed, and the doors and windows are not protected. However, we can't blame the doors and windows. Sometimes some confused parents also have factors. Therefore, when we are in a family with children and the elderly, doors and windows must be equipped with protective fences, which can greatly reduce potential safety hazards. The important thing is that the quality of doors and windows must pass. 3. Long-term impact on family health. With the expansion of urbanization, industrial waste gas and noise will only increase, and some toxic gas dust will generally enter the room through window gaps. If the quality of our doors and windows is not up to standard at this time, the harm can be said to be lasting. Therefore, for the health of family members, it is correct to choose doors and windows. 4. Poor energy-saving effect. Doors and windows are not only places for lighting and ventilation, but also places where buildings are very weak. The energy lost through doors and windows accounts for 45% to 50% of building energy consumption, while inferior doors and windows lose even more. Indoor air-conditioning or heating penetrates to the outdoors through the gaps between poor-quality doors, windows and glass, resulting in greater power consumption of indoor cooling and heating equipment. 263
