So after the opening year, many people have put the house decoration on the agenda. Before, I had been renting a house. It was not too hard for doors and windows to be soundproof. Now I have bought a new house to decorate myself. Therefore, I am very careful in choosing the decoration of doors and windows. Since I had to decorate myself and didn't want to be taken away, I spent a month reading almost all the articles and answers related to door and window decoration. I feel that many bosses have spoken very well, but it is a bit scattered. Today I will talk about my experience in selecting doors and windows. It's no use not to pull, it's all the ways and means of our common people to be grounded. In short, I divided the selection of doors and windows into three points: one look at the region and climate, two look at the space and environment, three look at the style and collocation. Next, let's explain in detail how to select the right doors and windows from these three aspects? 1. different geographical and climate doors and windows how to choose? China has a vast territory, a wide range of latitude and longitude, different terrain, various temperature and humidity changes, and a complex regional climate system. The doors and windows as the connection point between the room and the nature, the selection criteria are also different. (I) the climate difference between the north and the south is obvious, what should be paid more attention to the performance of doors and windows? 1. The north is dominated by temperate monsoon climate, hot and rainy in summer, cold and dry in winter, and more wind and sand haze. Therefore, in the decoration of doors and windows, attention should be paid to doors and windows with superior performance such as thermal insulation, sealing performance and wind resistance, so as to ensure that they can keep warm in the cold winter in the north and resist the howling of the north wind and sand. In the design considerations of door and window glass, it is recommended to use multi-layer insulating glass to maximize the cold insulation. In particularly cold areas, high-end aluminum windows are recommended. 2. The south is dominated by subtropical monsoon climate, with hot and rainy summers and mild and humid winters with more precipitation. Taking into account the "wet and cold" weather in the southern region and the "return to the south" factor, more attention should be paid to the water tightness and thermal insulation of doors and windows. And the south is a typhoon, rainstorm and other meteorological problems more frequent areas, so in the selection of doors and windows should also pay attention to wind resistance and drainage function. North-South climate differences also determine the performance of the doors and windows to choose. Generally speaking, the north should pay attention to heat preservation, heat insulation and wind resistance; the selection of doors and windows in the south should pay attention to air tightness and drainage function. Then what parts of doors and windows are mainly affected by these functions? What aspects should we pay attention to? We then understand ↓ ↓ What door and window components should be paid attention to for the key performance of (II) doors and windows? Thermal insulation: should pay attention to doors and windows multi-cavity structure, cavity perfusion materials, glass thickness, moisture-proof aluminum strips and other door and window components Sealing: Sealing strip is the key to the sealing of doors and windows. Inferior sealing strips are more susceptible to aging, corrosion, cracking, and falling off, which will lead to poor window sealing. There are various rubber strips on the market, such as EPDM rubber strips, thermoplastic EPDM/PP rubber strips and plasticized polyvinyl fluoride sealing rubber strips. At present, the best rubber strip should be EPDM rubber strips, because it is resistant to aging, corrosion-resistant, can effectively block noise from entering the room, and its performance can still be maintained above 85% after 15 years of use. In addition, the sealing of doors and windows is also affected by the sealing process of doors and windows. The whole frame is integrated to ensure the superior sealing of doors and windows. Many people will ignore the glue injection of the corner code when decorating the doors and windows, which will directly affect the sealing performance of the doors and windows. Corner code is the part where the profiles are linked. Generally, high-end system doors and windows use pin glue injection. It does not have a locator itself, and needs to be fastened and positioned by two pins, which well solves the problem of easy dislocation and loosening of the active angle code for a long time. The quality of the glue injection process is the key to sealing. For example, Xinhaoxuan, one of the top ten brands of doors and windows, has a national invention patent of "two-petal pin glue injection angle code". You can have a look. In addition to the connection mode of angle code + pin, it will also use high-pressure glue injection to fill the gap with glue through the diversion groove, and then stand still and wait for the glue to solidify to form a whole. This can effectively avoid air leakage and water seepage from doors and windows, and will greatly improve the sound insulation performance.

Content tips: plastic steel doors and windows are a new generation of door and window materials. Because of their high wind pressure resistance, good air tightness and water tightness, small air and rainwater penetration, low heat transfer coefficient, heat preservation and energy saving, sound insulation and heat insulation, and not easy to age, they are rapidly replacing steel windows and aluminum alloy windows.
