In winter, the northern cold areas generally like to seal doors and windows, because it will be warmer, but we often find that the sealing of doors and windows in winter is not very good, so what aspects should be paid attention to in the sealing of doors and windows in winter? The following Xiao Kai will introduce the following four points for attention: the main reason for uneven door and window profiles and air leakage lies in the tightness between the door and window sash and the frame, and the flatness of the profiles 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 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. 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 are cracks 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 strong 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. The above is the four precautions for sealing doors and windows in winter introduced by Xiao Kai. 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!

So, what aspects should be paid attention to in the sealing of doors and windows in winter? Xiao Kai will introduce the following four points for attention:

door and window profiles are uneven

door and window profiles. The main reason for air leakage lies in the close fit between the door and window sash and the frame. The flat profile is an important factor affecting the close fit. 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 the 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.
