In the winter, the northern cold areas generally like to seal the doors and windows, because it will be warmer, then, the winter doors and windows sealing work need to pay attention to what aspects. If the flatness of the profile is not enough or deformation, there will be a certain gap between the door and window sash and the frame, resulting in air leakage. The quality of the sealing strip is defective or aging sealing strip is the key to the sealing of doors and windows, and the quality of the sealing strip on the market is very different.

In winter, the northern cold areas generally like to seal the doors and windows, because it will be warmer, then, winter doors and windows sealing work need to pay attention to what aspects?
door and window profiles uneven
door and window leakage is the main reason for the tightness between the door and window sash and the frame, the profile of the flat is an important factor affecting the tightness. If the flatness of the profile is not enough or deformation, there will be a certain gap between the door and window sash and the frame, resulting in air leakage. 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 strips on the market is very different. The high-quality sealing strip has strong toughness, strong wear resistance, and is not easy to break; while the poor quality sealing strip is very fragile, easy to corrode and break, and cannot achieve the sealing effect. If the sealing strip is not installed well, uneven or bulging may lead to air leakage.
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 the door frame, window frame and wall due to hasty work or jerry-building. Especially in the old house, the wall is loose in the settlement process, and the tight degree between the door and window frame is reduced. If the waterproof glue is not evenly coated, the sealant is not fully done, or the expansion bolt is not nailed firmly, it will make it impossible to "fit perfectly" between the frame and the wall ". In the summer rain weather is easy to collapse glue, autumn and winter season is caused by air leakage.
hardware lock is not firm
door and window hardware quality is also closely related to the sealing performance. Especially the casement window, it relies on the hardware of the transmission to seal, if the transmission quality is not good, it is easy to leak from the edge of the window sash. At present, the door and window hardware sold on the market is divided into domestic and imported. Domestic hardware generally has two locking points, while imported hardware usually has three locking points. The principle is that when the doors and windows are locked, the lock points and lock seats are firmly buckled together, and cooperate with the hinge or sliding support to generate strong sealing pressure and elastically deform the sealing strip, thereby providing sufficient sealing performance for the doors and windows. Therefore, the lock is not strong hardware, will make the doors and windows of the sealing performance is greatly reduced.
