If the doors and windows at home are not sealed well, it is really a headache! In summer, the air conditioner runs out of the house, while in winter, the chilly wind blows in and dust comes in. So, what is the relationship between poor sealing of doors and windows, and how to solve it? Generally speaking, the poor sealing of doors and windows is related to the following factors: whether the doors and windows are leaking air or not has a great relationship with the material. If the material is poor, the compressive strength of the doors and windows frame will not work, and it will not stand the test of heavy wind and rain. Deformation may occur in two or three years. Once deformed, gaps may appear between the frame and the glass, and the sealing performance will be poor, then there are a series of problems such as air leakage and dust intake, and the longer the blowing time, the larger the gap, and it will be out of control. Solution: When purchasing doors and windows, pay special attention to the material and production process of doors and windows, and choose doors and windows made by regular companies with reputable protection. The installation of doors and windows is also an important factor in determining whether the doors and windows are sealed. Even if there are high-quality doors and windows, the installation is not in place will seriously affect the sealing performance of doors and windows. First of all, the doors and windows must be safe, otherwise the doors and windows may appear more and more crooked after a period of time, the gap between the window frame and the wall will become larger and larger, and air leakage is inevitable. Secondly, when installing doors and windows, you need to use foam to fill the gap between the window frame and the wall. After the foaming adhesive is cured, the sealant is evenly smeared around the window frame to prevent rainwater from penetrating into the room through the installation gap between the window and the wall, and also to prevent air leakage. It should be noted that it is necessary to apply glue on both sides inside and outside the window. Some workers try to save trouble and only apply glue inside, or apply glue at several points inside, which will lead to intightness. Solution: Find a professional installation team to carry out construction and supervise the installation and construction.

Door and window hardware accessories hardware accessories are the most frequent and most vulnerable products in doors and windows. If there is no high-quality hardware accessories, the performance of doors and windows will be greatly reduced. Specifically, the locking points and lock seats of hardware accessories are distributed around the entire doors and windows. When the doors and windows are locked, the locking points and lock seats are firmly buckled together and cooperate with hinges (hinges) or sliding supports to jointly generate strong The sealing pressing force causes the sealing strip to elastically deform, thereby providing sufficient sealing performance for the doors and windows, integrating the fan and frame, and improving the sealing performance. If the hardware accessories are of inferior quality, the doors and windows are of good quality, and their heat preservation and heat insulation are not much better. Solution: It is best to replace all hardware accessories, because hardware accessories not only involve sealing problems, but sometimes also involve safety problems; if the hardware accessories are loose or fall off, it is best to contact the manufacturer or tighten and install them yourself to ensure The sealing of doors and windows.
