Who knows what the cause of water seepage in aluminum alloy doors and windows is

The main causes and solutions of water leakage of aluminum alloy doors and windows:

First, the design of aluminum alloy doors and windows.

Aluminum alloy doors and windows are caused by defects in the structure of the design process, and the strength and rigidity of the main structure of the doors and windows fail to meet the index requirements of the local wind pressure resistance, such as small section and thin wall thickness, resulting in serious plastic deformation, cracking or damage of the stressed rods, hardware accessories, seals and bonding materials of aluminum alloy doors and windows under normal wind load.

As a result, the sealing of the door and window body fails to cause rainwater leakage, and Aowei Doors & Windows believes that the reason is that the product fails to accurately calculate and design the strength according to the specification, and does not pass the physical function test of wind pressure resistance before factory installation, resulting in water leakage of doors and windows.

Second, the design of waterproof structure is unreasonable.

The waterproof structure design of aluminum alloy doors and windows is unreasonable, the waterproof sealing level of the profile section is not enough, there is no multiple drainage channels, when the rainwater enters the aluminum alloy door and window cavity and enters the indoor intelligent doors and windows under the effect of indoor and outdoor wind pressure difference, and the rainwater that enters the aluminum alloy door and window cavity can not be smoothly discharged outdoors through the aluminum door and window drainage system and stays in the doors and windows to cause water accumulation and leakage.

3. Caused by differences in materials and accessories.

Caused by the disagreement between the materials and accessories used by aluminum alloy doors and windows manufacturers, the quality of auxiliary materials such as sealants, rubber strips and hardware accessories used in aluminum alloy doors and windows is unqualified.

If the sealant is outdated or counterfeit glue, the resistance to displacement is poor, easy to crack, the rubber strip is too hard, the anti-aging time is short, the shrinkage is easy to break, the quality of hardware accessories is too poor, and it cannot withstand multiple openings to break or deform and cause loose closure, resulting in water seepage.

Fourth, caused by production and installation.

The failure to meet the quality requirements during the production, processing and installation of aluminum alloy doors and windows also causes water leakage, because the assembly size of aluminum alloy doors and windows is not well controlled when they are installed on site.

As a result, the positions of overlap seals are misplaced with each other or the lap size is insufficient, the corner seams of the frame fan are not sealed, not glued, or there is a gap due to sufficient pressure, the fastening screws used to fix the door and window frames are not sealed with glue, and the surface of the sealing part is not cleaned when sealed with sealant.

Doors and windows are an important part of the house, the quality of doors and windows will directly affect people's living experience, what are the reasons for aluminum alloy doors and windows leakage? How to deal with water leakage of aluminum alloy doors and windows? Let's take a look

What are the causes of water leakage in aluminum alloy doors and windows?

1. Design defects of aluminum alloy doors and windows.

Aluminum alloy doors and windows in the design process of the structure of the defects caused by defects, the main structure strength and rigidity of the doors and windows, failed to reach the local wind pressure resistance index, or the section is small, the wall thickness is thin caused by the aluminum alloy doors and windows of the stressed rods, hardware accessories, seals and bonding and other materials under the action of normal wind load under serious deformation, cracking or damage, etc., resulting in the failure of the sealing of the door and window body, and the situation of leakage.

2. The design of the waterproof structure is unreasonable.

The waterproof structure design of aluminum alloy doors and windows is unreasonable, the level of waterproof sealing of the profile section is not enough, and there are no multiple drainage channels, so when the rainwater enters the aluminum alloy door and window cavity under the action of indoor and outdoor wind pressure difference, and enters the indoor intelligent doors and windows, and the rainwater in the aluminum alloy door and window cavity can not be smoothly discharged outdoors through the aluminum door and window drainage system, and is stranded in the doors and windows, resulting in the phenomenon of water leakage and accumulation.

3. Differences in materials and accessories materials.

The quality of sealants, rubber strips and hardware accessories used in aluminum alloy doors and windows is unqualified, such as outdated sealant or counterfeit fake rubber, its anti-displacement can be poor in dry penetration, easy to crack, hard rubber strips, short anti-aging time, shrinkage and easy to pull off, and the quality of hardware accessories is too poor, and it can not withstand multiple openings to break or deform and cause loose closure, resulting in water seepage.

4. Caused by production and installation.

The quality requirements cannot be met in the process of production, processing and installation, because when the aluminum alloy doors and windows are installed, the assembly size is not well controlled, resulting in the dislocation of the overlap seal or the lap size is insufficient, the corner seam of the frame fan is not sealed, the glue is not glued, or there is a gap due to sufficient pressure, the fastening screws used to fix the door and window frame are not sealed with glue, and the surface of the sealing part is not cleaned when sealed with sealant.

How to deal with water leakage of aluminum alloy doors and windows?

1. First of all, check the leakage at the **, window, the top surface of the window, the underground or both sides of the leakage.

1) The window itself leaks: It may be that there was a construction error when installing the window at that time, and there was leakage.

2) Water leakage on the top of the window: Glue the glass at the joint between the window and the wall outside, and the same way should be used on both sides.

3) Underground water leakage: first see whether the platform outside the window has gone slope, if not, brush some waterproof paint, and then use cement to wipe the slope tremor, and then put glass glue on the joint between the window and the slope.

2. Check the drainage hole of the window frame groove, if it is not just facing the window sill outside the window, please seal the original hole and re-drill the hole.

3. If there is a gap between the window frame and the window sill outside the inspection site, knock off and shovel off the original seal, and then buy weather-resistant glass glue for soft sealing, and then seal it with cement mortar, do waterproofing, tile pasting, etc.
