In winter, cold areas generally like to seal doors and windows, because it will be a little warmer, then, winter doors and windows sealing work need to pay attention to what aspects?
1. Uneven profile of doors and windows
The main reason for the air leakage of doors and windows is the close degree between the door and window sash and the frame, and the flatness of the profile is an important factor affecting the close degree. 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.
2. Sealing strip is indispensable
The 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. I-ECO coated sealing strip is a good choice. It has achieved excellent results beyond all traditional products in aging resistance, fatigue resistance, compression deformation test, compression force test, heat conduction K value test, water intrusion, water permeability and other tests. At the same time, the coated sealing strip is energy-saving and environment-friendly, sound-proof and noise-reducing, anti-strong ultraviolet, non-toxic, does not react with any paint or detergent, and caters to the green health theme of the new era.
3. 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 tightness 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.
4. Hardware lock is not firm
The quality of door and window hardware 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. When the doors and windows are locked, the lock point and the lock seat are firmly buckled together, and cooperate with the hinge or sliding support to jointly generate a strong sealing pressure, so that the sealing strip is elastically deformed, 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.
