Doors and windows seal leakage is not necessarily a good question without

Window air leakage
>> One reason: poor material
Now the windows broken bridge insulation material to aluminum, steel windows for the mainstream, aluminum doors and windows have been sealed because of their poor performance will be phased out. But even purchased a plastic-steel windows and windows broken bridge, experts suggest that it should pay attention to materials.
"Whether the window air leakage great relationship with the material." Decoration industry Beijing Branch Director of Engineering Huzeng Guang said that if the material is poor, windows of deformation occurs two or three years, once deformed, the sealing performance poor, it leakage will occur, so it also reminds owners in the purchase of the windows to be extra careful material.
Solution: You can only find windows manufacturers to solve.
>> Two reasons: installed in place even if the material has excellent windows, the installation process is not in place to determine if the window is an important factor in air leakage. First, the windows must Yasumasa, otherwise use the window may appear after a period of time more and more crooked windows circumstances, the gap between the window frame and the wall also will be increasing, air leakage inevitable.
Secondly, the reporter has learned that the windows of the installation, you need to hit styrofoam filling the gap between the window frame and the wall. Styrofoam be cured, and then in the sash around evenly with sealant, both to prevent rainwater from the window and wall mounting gap penetrate indoors, but also to prevent air leakage. But also in the internal and external sided sizing windows, but Hu Zengguang introduction, some workers the easy way, just inside a plastic, or gluing several points inside, Mifengbuyan. Even outside playing styrofoam, but a year or year and a half or so will chalking, summer leaks, leakage situation occurs in winter. In addition, when the renovation, home improvement workers found Mifengbuyan sash with Qiangfeng gap will fill the putty from the inside, but a long time, there will be a remote seam, causing leakage.
Solution: In the first case have to find windows manufacturers. If only the windows inside the glue did not play well, the gap is relatively small, it can affix themselves Masking toward the gap in the Fixed Length plastic seal sealant can be marked; external glue if there is a problem you need to contact the workers to operate it.
>> Three reasons: not to force windows accessories Another important reason is that air leakage sealing fittings out of order. The most common is the seal aging crack, a direct result of poor performance window seals; there is a foam rubber is too soft, the use of powder occurs after a few years, resulting in the gap between the window frame and the wall becomes large, resulting in air leakage.
Solution: Can you change the bolt security seals, using EPDM rubber is better, or poorer quality rubber strips can; if they can not operate, to find street shop workers doing steel window replacement cost will not too much. As for the foam, need to find workers to operate, styrofoam cured, the landlord can tweak their look, struggling to pinching the quality is better.
