In winter, people usually like to seal doors and windows, because it will be warmer. So, what aspects should we pay attention to in the sealing work of doors and windows in winter? The following small editor will introduce the following four precautions:
01. Door & window profile uneven
the main reason for air leakage between doors and windows lies in the tightness between doors and windows and frames. The flatness of profiles is an important factor affecting the tightness. If the flatness of the profile is not enough or deformed, there will be a certain gap between the door and window fan and the frame, causing air leakage.
02. The quality of sealing strip is defective or aging
sealing Strip is the key to the sealing of doors and windows. At present, the quality of sealing strip on the market varies greatly. High quality sealing strip has strong toughness, strong wear resistance and not easy to break; While poor quality sealing strip is very fragile, easy to corrode and break, and can not achieve the sealing effect. If the sealing strip is not installed well, there will be uneven or bulging, which may lead to air leakage.
03. There is a crack between the frame and the Wall
during the installation of doors and windows, many winter door and window sealing workers did not do a good job of sealing between door frames, window frames and walls due to rush to work or cutting corners. Especially for old houses, the Wall loosens during the settlement process, and the density between the wall and the door and window frame decreases. If the waterproof adhesive is not spreadability, the sealant is not enough, or the expansion bolt is not nailed firmly, it will make the frame and the Wall unable to be "tightly stitched". It is easy to collapse glue in rainy weather in summer and air leakage in autumn and winter.
04. Hardware lock is not firm
the quality of door and window hardware is also closely related to the sealing performance. Especially casement window, it relies on the actuator of hardware to seal. If the quality of the actuator is not good, it is easy to leak air from the edge of Casement. At present, the door and window hardware sold in the market is divided into domestic and imported hardware. Domestic hardware usually has two locking points at a time, while imported hardware usually has three locking points at a time. The principle is that when the doors and windows are locked, the lock points and lock seat are firmly fastened together, and cooperate with hinges or dagger to jointly generate strong sealing pressure, which makes the sealing strip elastically deformed, so as to provide sufficient sealing performance for doors and windows. Therefore, hardware with unstable locking will greatly reduce the sealing performance of doors and windows.
The above is the four precautions for sealing doors and windows in winter introduced by Xiao Bian. If you find that the doors and windows in your home are not well sealed in winter, you can check them from these four aspects!
