White steel doors and windows, titanium gold doors and windows why air leakage? And how to solve it? Experts explained that the door and window air leakage in addition to sealing, and installation and accessories are closely related, can be gradually investigated, and then formulate countermeasures against "air leakage".
Air leakage of doors and windows
"One reason: poor material."
Nowadays, the windows are mainly made of insulated aluminum and plastic steel windows. Aluminum alloy doors and windows have been gradually eliminated because of their poor sealing performance. But even if purchased the plastic steel windows and broken bridge aluminum windows, the expert tips should also pay attention to the material.
"White steel windows leak air and material is very large." Yezhifeng Decoration Beijing Branch Project Director Hu Zengguang said that if the material is poor, the windows will be deformed in two or three years. Once deformed, the sealing performance will be poor, there will be air leakage, so this also reminds owners to pay special attention to the material when choosing windows.
Solutions to windows and doors can only be found by window manufacturers.
Reason 2: Installation is not in place, even if there are good material windows, installation technology is not in place is also an important factor to determine whether the window air leakage. First of all, the window must be straight, otherwise the window may be used for a period of time after the window is more and more skewed, the gap between the window frame and the wall will become larger and larger, air leakage is inevitable.
Secondly, according to reporters understand that the window in the installation, the need to make foam filling the gap between the window frame and the wall. When the foam is solidified, the sealant is evenly applied to the periphery of the window frame to prevent rain water from infiltrating into the room through the installation cracks of the windows and walls, as well as air leakage. And need to sizing both inside and outside the window, but Hu Zengguang introduced, some workers try to save trouble, only in the internal glue, or in the interior of a few points glue, seal is not strict. Even if the external foam, but a year or about a year and a half will be pulverized, summer water leakage, winter air leakage will occur. In addition, decoration, home decoration workers found that the window frame and wall seam seam seals not tightly, it will be filled from the inside putty, but a long time, there will also be a fine seam, resulting in air leakage.
Solution: first, we must find windows and doors manufacturers. If only the glue inside the window is not done well, if the gap is relatively small, you can paste your own fine-grained paper, put sealant into the gap can be; if the external glue problems, you need to contact workers to operate.
"Reason three: another important reason for accessories not to force the windows to leak is that the sealing parts are out of order. The most common is the aging and cracking of the sealing strip, which directly leads to poor sealing performance of the window; another is that the foam is too soft, after several years of use, it will be pulverized, resulting in the gap between the window frame and the wall widened, resulting in air leakage.
Solution: You can replace the sealing strip yourself, using EPDM rubber is better, or a slightly worse quality of rubber and plastic strips can also be; if you can not operate their own, looking for Street plastic window shop workers to replace the cost will not be too much. As for the foam, we need to find a worker to operate, after the foam cured, the owner can pinch it by himself, it is difficult to pinch the quality of better.
Hu Zengguang introduced, can stand on the edge of the window, feel where the wind is coming from, if it is a frame leakage, it is a problem with the sealing strip; if it feels that the window is not a problem, it is not tightened glue.
"Cause is similar, processing is similar.
The leakage of doors is similar to that of windows. Hu Zengguang introduced the following reasons: 1. Wooden door quality is too poor; 2. During the use of the door deformation, the door seam becomes larger; 3. Outdoor door door sealant aging; 4. Outdoor door door in the installation, the gap between the door frame and the external wall is larger, some installation without sealant seam, or only with sealant plugged the outside seam, inside. The part is not sealed, and there will be air leakage for a long time. "If the entrance door is facing the corridor, it will feel very windy."
Solution: Because the quality of the door caused by the problem, if it does have a great impact, you can contact the manufacturer or replace the wooden door; if only the problem of sealing tape and gluing, replace the adhesive tape and re-gluing can be.
In addition, Ms. Yu also put forward the special situation of air leakage at the bottom of her door. "My house is an old building, and the door is old-fashioned. The door against theft is an iron frame door. Inside is a wooden door. When winter arrives, she feels like standing in the living room. The cold wind pours in through the crack under the door and dares not stay in the living room. Is there a good solution?"Said Hu Zengguang, Ms. Yu could consider going to the building materials market to buy a kind of sealant tape, one side is the feeling of velvet, the other side is a Band-Aid-like can be pasted on the door around the frame, once closed the door, the gap will be much smaller, it can solve the problem of air leakage, but this seal. The adhesive strip needs a doorframe. Some old-fashioned entrance doors are "sweeping doors", the same as indoor doors, no doorframe, if Ms. Yu's home is such a door, you can only consider to do a 1 cm high cement table or wooden doorsill, generally under the door seam is 4-7 mm, after building the threshold can basically block the gap.
