When installing broken bridge aluminum doors and windows, the technology is not in place, there will be air leakage, rain leakage, and Casement is not in the same plane. Casement window the air leakage place is to open around the fan. The air leakage seriously indicates deformation, it is not suitable to replace the opening fan.
There are probably several situations: 1. Whether the sealing strip has the phenomenon of aging and cracking, and if so, replace the sealing strip again. 2. Silicon sealant whether there are cracking phenomena such as shedding, aging, etc.
3. Broken Bridge aluminum whether the hinge or hinge of the window is loose, otherwise it needs to be replaced, whether the handle is in place, and whether the lock point is loose or shifted.
Generally, the air leakage of windows may be leather strap. The seal is not good, and the quality leather strap is replaced. In addition, it may be that the locking position of the driving rod driven by the handle needs to be adjusted (usually it is the European standard transmission system, and the locking Rod two-point lock can use 5mm hexagon to adjust the tightness when the window is closed, too loose will make the window leak due to poor sealing, resulting in air leakage), if the handle is not tight, if the handle of the self-tapping screw may be loose, replace the screw (the general treatment method is to change the first size screw, or lengthened screws) if it is hexagon socket head cap screw, it is generally enough to tighten the screws with 5mm Allen wrench.
