When the aluminum alloy doors and windows in the home have been used for a long time, there will always be some problems, such as leaking doors and windows. Many people feel that the house in the home is not right when they live there. I don't know where the problem is, all kinds of water leakage will occur in rainy days,

(Ii) reasons
1. Door and window frames and for walls cement mortar caulking.
2. The glue injection between the door and window frame and the wall is not strict and there is a gap.
3. The craft of doors and windows is unqualified, and the combination between window frame and Casement is not strict.
4. The installation of Casement sealing strip is unqualified, and water seeps into the Casement glass seam.
5. The window frame has no drainage hole.

note above
1. Doors and window frames and walls shall not be caulked with cement mortar. It should be connected elastically and sealed with sealant, without gaps.
2. Before installation, check whether the doors and windows are qualified, whether the combination between the window frame and the Casement is strict, and whether the installation of the Casement sealing strip is qualified.
3. There is a gap of more than 50mm between the window frame and the hole, so that the window sill can make a running slope.
4. Drain holes should be drilled for the lower frame and track root of the outer frame.
Keep doors and windows watertight

the watertightness and air tightness of doors and windows are the key to measure the quality. According to the practical engineering experience, pay attention to the following points, and doors and windows will not leak air and water.
First: since the general aluminum doors and windows are recessed, the window top must drip olecranon to prevent the capillary action of rain.
Second: Around the aluminum alloy doors and windows should be coated with waterproof coating (asphalt) about 300mm from the window side. Before making waterproof coating, the ash at the position to be coated should be cleaned and lead water oil should be coated.
Third: waterproof agent concrete should be added around the window to seal it. Please note that waterproof agent should be added, because when ordinary concrete is solidified, the concrete loses water due to water reaction, and the inside is hole-shaped, water will seep from the hole to the room, while adding waterproof agent of concrete is dense inside and will not seep water.
Fourth: the handover position between the window frame and other materials should be disposable silverware set.
Fifth: add a water covering plate to the top of all open windows to prevent rainwater from flowing into the room from the seam upward from the opening.
Sixth: the sill plate at the bottom of the window and the glue-line of the window should be designed outward rather than upward, and the sill plate must also be designed with an outward slope.
Seventh: if it is a single glass, the bottom of the window should design the condensate diversion hole at a quarter of the glass.
Eighth: the construction should strictly handle the interface around.
Another is that the waterproof layer of the wall near the window is damaged and causes water leakage.
In an old house with a long room age, the waterproof layer of the wall around the window is easily leaking; In addition, when the old house is transformed and replaced with Windows, the unprofessional window removal causes the damage of the waterproof layer of the exterior wall. If it is not repaired in time, after installing the new window, there is a high possibility of water leakage.
For balcony with serious leakage, waterproof should be redone, especially the waterproof of the top surface and wall surface. You can also add a water barrier above the wall to reduce the filler course Impact of rainwater on the window and wall. During maintenance, good sealing materials should be selected to carefully block all leaking places.
