The connection part between aluminum doors and windows and the wall of the opening is the most common part of rainwater leakage,according to China aluminum single hung window factory

The main reasons are as follows:

⒈Because of the defects of the building wall adjacent to the door and window openings, rainwater can penetrate the room directly through the wall under the action of wind load, especially when the external wall is pasted with facing bricks, the phenomenon is more common, because the gaps between the facing bricks often have micro cracks exist. This phenomenon is often mistaken for water leakage in doors and windows because the water seepage part is close to the doors and windows.
⒉The filling material does not cover the gap between the door and window frame and the wall, forming an empty valley phenomenon or cracks.
⒊The adjustment pads for fixing the door and window frames remain in the door and window frames, or there is no secondary filling after removal.
⒋The gap between the aluminum doors and windows and the wall of the opening is not filled with qualified materials as required, such as the marking of the waterproof cement mortar is different or the proportion is different.
⒌The full size of the wall opening does not meet the design requirements, causing the gap between the full size of the doors and windows and the wall to exceed the delineated range. Too small gaps can make it impossible to fill materials, and too large gaps make it difficult to fix doors and windows and make it difficult to fill. Cracks etc.
⒍The fixed connection between doors and windows and the opening is not strong, which causes the doors and windows to move under the action of wind load and cracks in the sealing material.
⒎After the doors and windows are installed, the joints between the outside of the doors and windows and the wall are not sealed, or the sealing fails.

⒏For doors and windows with corners or connected forms, the upper part of the connecting rods located at the corners or connected parts is not blocked, which is easy to cause the leakage of rainwater to enter the room from top to bottom.

However, according to China aluminum single hung window factory,generally when making and processing aluminum alloy doors and windows, the processing side will punch out regular holes on the glideslope (that is, the aluminum alloy on the bottom side of the room and the outside side of the room) with a punch to prevent water from accumulating on the The chute goes uphill, and the middle part is affixed on both sides of the chute, which is a thicker double-sided tape to prevent water from flowing out of the gap. Before assembly, it will be sealed on the sides (the left and right sides of the aluminum alloy frame) Root aluminum alloy) and put on the sealing top on the hook up of the inner frame.
Matters needing attention during construction
Matters needing special attention during installation and construction in coastal areas

Due to the relatively large amount of salt and alkali contained in the wind and rain in coastal areas, some areas have clean sea sand that has not been desalinated, which is strictly prohibited by national standards. The corrosion problem of aluminum alloy doors and windows is relatively serious, and special attention should be paid. In addition to the above procedures, the following procedures should be strictly followed,according to China aluminum single hung window factory:

⒈The aluminum doors and windows transported into the construction site should be placed in a well-ventilated, dry and clean warehouse.
⒉The height of the sleeper surface of the place where it is placed should be >=100mm, and each stack should not exceed 15 molds (fans). Each mold (fan) should be leveled with soft materials to prevent crushing and damage between aluminum alloy and hardware. Rubbing against each other destroys the protective film on the surface of the profile.
⒊There must be a drip line at the door and window opening, which should be inspected before installation. Because the rainwater flowing through the wall made of sea sand is very corrosive, it must be guarded against.
⒋It is advisable to use the card type to install the iron sheet to minimize the amount of processing that damages the aluminum alloy protective layer.
⒌The joint part of aluminum alloy profile should be sealed with neutral glue to prevent rainwater from entering the inner cavity without protective layer. According to experience, corrosion usually starts from the inner cavity without a protective layer.
