According to Xiao Bian learned Jinke Panther waterproof engineering, building doors and windows leakage occurs, repair is more complicated. One is not easy to determine the location of leakage, maintenance of a relatively long duration; two is not easy to fix, often after several repairs, the owners of the daily life will cause a greater impact. Therefore, as a professional and technical personnel in the construction industry, we have the responsibility to analyze the construction of doors leakage link, to find out the reasons for the leakage problems, from the practice of refined design, material processing to finished installation and other aspects, intensifying quality management in construction, the real from the source of the prevention and control of leakage the problem, to ensure the quality of the project.

After observation, found that there are mainly the following aspects of the problem of the leakage of doors and windows:

1, large area of the window with a single piece of glass, there is no reasonable separation, additional reinforced frame, wind pressure, doors and windows vibration led to the gap in the water, doors and windows design is not reasonable lead to leakage.

2, the window frame and window wall between the sealant bubbles and cracking, part of the winter of a plastic doors and windows, sealant loss of bond strength, it can not seal leakage.

3, the window frame is directly fixed on the insulation layer, the local take waterproof strengthening treatment, resulting in some parts of the storm door window insulation leakage layer and the bladder wall.

4, the door and window frame material splicing gap, bolt hole does not have a rubber, or playing plastic is not dense, leading to leakage.

5, the hinge adjustment is not in place, PVC strip less elastic with the sash processing large deviation, resulting in gaps between the door and window frame and the sash is large, seal leakage.

6, door and window profiles and glass filled with glass, gap between the plastic seal, in the wind pressure, the doors and windows and glass doors and windows between the tight seal leakage.

The 7 part set and a drain hole and the discharge hole improper closed drain hole in the plug pressure, cause an inward flashing.

The 8 part, the window exists hollowing, cracks, plastering sand, lead seal leakage, water leakage, partial roof windows, individual window flashing down the slope, leading to water leakage.
