Doors and windows choose different materials, insulation effect is different, aluminum alloy doors and windows because of its bright appearance, strong and durable occupy the market mainstream. However, the competition between the aluminum alloy processing industries is very fierce. In order to reduce the cost, some processing workshops have made up their minds on materials and arbitrarily use low-quality materials for combined processing. Eventually, the thermal insulation performance of aluminum alloy doors and windows is not good, the air tightness is not good, and the air leakage is easy. In this regard, a brand door and window merchant said: "the door and window materials of 1 200 yuan per square meter produced by the aluminum alloy processing workshop along the street are inferior, and there is no wind proof and thermal insulation at all. Some high-end brand aluminum alloy doors and windows materials and hardware are generally good, although the price is higher, but its airtightness is incomparable with low-quality door and window processing workshops. " Plastic steel doors and windows are favored by more and more consumers because of heat insulation, sealing and sound insulation, corrosion resistance, anti-aging, elegant and beautiful. However, the plastic steel windows have low sand resistance and water tightness, large shading area and high thermal expansion coefficient of window frames, which lead to the problem of photothermal aging.

The price of plastic steel doors and windows is higher than that of aluminum alloy doors and windows. Generally, double glass casement windows cost about 400 yuan per square meter, and most of the casement windows with insulating glass are more than 1000 yuan per square meter. As the traditional use of wooden windows can lead scenery, ventilation, diversion, lighting, heat insulation, sound insulation, insulation, and coordination of the interior decoration, is the banner of creating an indoor environment, is gradually becoming the lifestyle trend of high-end doors and windows consumption. How to keep warm and windproof has become the most important problem in winter. From the present point of view, the doors and windows used by developers in the newly developed commercial houses have been very practical. However, due to the lack of airtightness, the windproof and thermal insulation performance of some doors and windows are greatly reduced in winter. The transformation or replacement of functional doors and windows is considered by more and more consumers. Improper installation of doors and windows is the culprit. Industry insiders introduce: Generally speaking, windows have a certain service life, in normal use, there will be no wear and aging of sealing strips in a short period of time.

However, frequent opening and closing of windows may lead to premature aging of sealing strips or deformation of profiles. Therefore, improper installation is the most common cause of air leakage. Doors and windows must be installed with good glue, doors and windows must pay attention to various accessories and details. When we install doors and windows, the use of bad door and window glue, generally after a few months around the door and window sealant on the phenomenon of degumming. Good glue should be soft and elastic. Poor quality coating on the wall, poor adhesion, and the door and window glue can not be well integrated. Once it falls off, it will not be able to seal and block water, so even if you buy a good door and window, you must check whether other auxiliary materials provided by the manufacturer are available. If the quality is not good, you must replace it.

Improper installation is reflected in many aspects. It may be that there is a gap between the window frame and the wall, resulting in air leakage; it is also possible that the sealing strip is not installed properly, resulting in uneven or bulging, and air leakage may also occur. Most of the air leakage of the door is on the entrance door, and the main reason is the tightness problem. Because there is a certain gap between the door and the frame, if it is not handled properly, it will become the root of the air leakage. "At present, many entrance doors are steel security doors. Whether the door is well sealed has a lot to do with the flatness and sealing system of the door. If the flatness of the door is not enough or deformation occurs, there will be a cold wind quietly invading.".
