What are the common problems with aluminum windows and doors?

1, aluminum alloy doors and windows leakage phenomenon

Aluminum alloy doors and windows hardware reasons: due to the window hardware fasteners loose or product quality problems, the formation of window closure bad, resulting in wind leakage. These problems can be solved by fastening the window hardware or quality problem parts replacement;
Aluminum environmental doors and windows adhesive tape reasons: due to the aluminum alloy doors and windows used in the sealing adhesive tape quality is not qualified, in the use of the use must be in the use of the adhesive tape to lose elasticity, the formation of the system assembled in the center of the gap can not be sealed, resulting in wind leakage.

The EPDM sealing tape that meets the national standard can be replaced and processed; Aluminum alloy doors and windows fan quality problems: due to errors in the production size of aluminum alloy doors and windows fan, can not meet the lap requirements of the profile system, resulting in doors and windows fan leakage. This type of problem can not be repaired, only replacement.

2, window sagging

Aluminum alloy doors and windows hardware reasons: window sash due to hardware fasteners loose or product quality problems, the formation of window sash sagging, switch sash difficulties. Such problems can be solved by fastening the window hardware or replacing the hardware quality problem parts;
Window sash deformation causes: due to the production process of window sash is not strictly in accordance with the standards, the placement of window sash glass gasket is not in line with the requirements, resulting in uneven force on the window sash, resulting in window sash deformation and sagging. Such problems need to remove the window glass, first reset the deformed window sash, and then install the window glass, the correct placement of the glass cushion processing;

3, the installation is not solid, the overall rigidity is poor.

Aluminum alloy door and window frames crack with the wall connection; when pushing and pulling or opening doors and windows, the frames and sashes shake; when squeezed by the wind or pushed and pulled by hand, the window frames are deformed and shaken, giving people a sense of insecurity.
Solution:

① aluminum alloy doors and windows should be based on the size of the door and window opening, installation height, the selection of suitable profiles or steel profiles.

② window and door frame installation, should be used with the wall connected to the joints. The joints should be made of thin steel plate with a thickness of not less than 1.5mm and anti-corrosion treatment. Usually use expansion bolts, shooting pins buried in the wall connection.

③ After the installation of aluminum alloy doors and windows, the door and window frames can be pushed hard to check, such as found shaking or deformation, should be promptly reinforced.

4、Water leakage of aluminum alloy doors and windows

Aluminum alloy doors and windows hardware reasons: due to the window hardware fasteners loose or product quality problems, the formation of window closure is not strict, resulting in water leakage. These problems can be solved by fastening the window hardware or quality problem parts replacement;
Aluminum alloy doors and windows adhesive strip formation reasons: due to the aluminum alloy doors and windows used in the sealing adhesive strip quality is not qualified, in the use of the time must be used, the adhesive strip loses its elasticity, the formation of the center of the gap in the system assembly can not be sealed, resulting in water leakage. The EPDM sealing tape that meets the national standard can be replaced;

Aluminum alloy doors and windows gluing reasons: due to the quality of aluminum alloy doors and windows outside the eaves glue, resulting in gluing parts of cracking, water leakage. This kind of problem can be dealt with by silicone sealant gluing from the beginning; Aluminum alloy doors and windows fan production quality formation: due to the aluminum alloy doors and windows fan manufacturing size error, or production process does not meet the requirements, resulting in water leakage of doors and windows. These problems can be solved in the short term, can not be solved, can be repaired.

Wall insulation layer leakage formation: after sweeping away the above problems, the leakage of aluminum alloy doors and windows is still not solved, then this leakage is due to the formation of the insulation layer and the center of the wall into the aluminum alloy doors and windows and the center of the wall into the formation of water. This kind of water leakage problem is more complicated to deal with the process, need to remove the window glass, pick out the window sill on the outside eaves, aluminum alloy doors and windows and the center of the wall plastered with waterproof mortar from the beginning of the plaster, sanding weather-resistant silica gel outside the eaves, from the beginning of the installation of the window glass processing.
