In winter, the cold areas in the north generally like
door and window sealing, because it will be warmer, then, what aspects should be paid attention to in winter door and window sealing work?
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. Hardware with unstable locking will greatly reduce the sealing performance of doors and windows.
