The most primitive definition of doors and windows is the hole in the wall, which is to provide people with access to the exit, as well as shelter from wind, fire, and theft. The space outside the doors and windows is public, and the space inside the doors and windows is private. It can be seen that the doors and windows also play a role in separation. Therefore, there will be people who say that "the door is closed, it is the home world." However, the significance of doors and windows is not just that. Good doors and windows are unforgettable and impressive. Even the interior doors can add different feelings to each room in the living room. The person realizes the beauty that is within easy reach. Therefore, the unique doors and windows can make the house full of personality. In a good house, its doors and windows should not only have practical and safe functions, but also give people a sense of beauty. This requires a reasonable design of the doors and windows according to the conditions of the foundation of the house before the renovation to achieve safety, practicality, and beauty. And other multiple effects. 1, door design considerations The gate is the mouth of the house, so it should be clean and bright, and it must not be piled up. Although the two doors in the room can be opposite to each other, they should not be completely overlapped with each other, nor should they be completely staggered. If people open the door to see the wall or see the other room far away, it will certainly affect people. Therefore, The size of the door should be appropriate, too large or too small is not ideal, but also to meet the principle of large rooms open the door (such as the bedroom, living room or guest room), a small room to open a small door (such as bathroom or kitchen). The living room door is the focal point of the living room. Generally, the glass model door should be selected because the living room usually has a balcony. The glass door can provide sufficient light to the room. However, the living room door should be coordinated with the bedroom so as not to affect the overall design style. The bedroom door should be completely partitioned, because the bedroom requires higher privacy, security and absolute silence, so solid doors should be chosen. The bathroom door is smaller than other doors. Due to the small space, a transparent door fitted with frosted glass and louvered vents can be used, which can increase the light transmission, increase the ventilation, and make the confined space appear spacious. And lively. The kitchen should have been clean and bright. Therefore, the kitchen door should also be based on the consideration of other doors to increase transparency in order to allow better lighting. For example, in the upper half of the kitchen door, patterned glass is used, which is both beautiful and practical. When entering and exiting the kitchen, you can see whether there is anyone on the opposite side and bring more light to the house. 2, window design considerations We often say that "the eye is the window of the soul." Losing one's eyes is tantamount to losing hope. The windows of the room are like human eyes and play an important role in the home. Air and sunshine are the essential factors for human survival. If you can't breathe fresh air for a long time, or you don't receive enough sunlight, people can easily get sick or become mentally ill. Therefore, the room must have large enough windows. To increase the transparency of the interior, however, the design of the windows is not as great as possible because the structure of the windows is constrained by the size of the moment of inertia of the “Lanâ€. To achieve the large size required by people, it can only be based on the traditional doors and windows. Increase the inertia moment of "Lizhe" to meet the wind pressure resistance performance, and in this way, this will increase the size of the frame profile of the window, not only affecting the appearance of the appearance, but also increasing the cost of the product. The problem. In addition to light problems, the convection of indoor air is also a very important indicator. From this point of view, the windows should be open. For example, there are windows in opposite locations in the south and the north, and in opposite locations in the east and west. In addition, the windows should be able to fully open, preferably outward, open inward, not inclined upward or downward, only such a window is the most beautiful, but also to ensure the circulation of air in the house, to ensure the health of occupants .
