Close to the deep winter, the cold wind outside the house blowing, many people generally stay in the house at this time, dare not go out. Even if there is a cold wind in the aluminum alloy room, you may think that there is a cold air leakage in the room. What is the cause of air leakage of aluminum alloy window? And how to solve it? Here we will explain the solution of air leakage of aluminum alloy window!

Causes of air leakage of aluminum alloy windows

Reasons for air leakage of aluminum alloy window 1. Nonstandard fabrication

(1) The windows may not have drainage holes, especially for sliding windows. All rainwater accumulated in the sliding frame groove can not be drained out. When it is full, it will seep into the house. Or when the external window sill is pasted with tiles, the drainage hole is not blocked. The rainwater in the sliding frame slot will all seep into the wall, resulting in air leakage of aluminum alloy window.

(2) The window should choose the special sealant strip with good elasticity, standard thickness and matching with the profile to ensure that the glass strip is pressed tightly and seamless. The sealing strip must be a whole piece, and the interface must be selected at the upper part of the window, and it is better to connect with glue. The natural rubber has a bad smell, and it is easy to crack.

The reason of air leakage of aluminum alloy window 2. The gap between the window and the window sill of external wall is not tight

After the gap between the wall and the window is filled with foaming agent, the gap between the window and the wall must be sealed with waterproof sealant outside, provided that the gap is not too large. If the gap is too large, the waterproof mortar must be filled and leveled first. After the doors and windows are installed and fixed, the windows should be filled with foaming agent. After curing, they should be cut flat. Finally, the sealant should be applied on both sides of the outer frame. This is a very careful manual work. First, clean the surface of the wall with a clean brush, then apply waterproof sealant, and then use the hand with soapy water to smooth it. This treatment is not only beautiful and smooth, but also fills the capillary cracks between the wall and the window. But pay special attention to the fact that the walls must be dry.

(1) The lower frame of the window is connected with the window and the wall with explosive screws. The head of the explosion screw in the window frame should be sealed with sealant, so that the water in the window frame will not seep into the wall along the explosion screw, but will drain out along the drain hole. This aluminum alloy window air leakage phenomenon is quite secret, aluminum alloy window air leakage, we always focus on the waterproof between the wall and the window gap, repeatedly repair or air leakage, so this problem is most worthy of the attention of the door and window industry installation personnel.

(2) Nowadays, many windows are corner windows, and there are many splicing places. These places should be sealed with sealant. If it is not sealed, it will become a hidden danger of leakage, so the air leakage phenomenon of aluminum alloy windows is also quite secret.

Reasons for air leakage of aluminum alloy window 4. The installation personnel are not professional

Old houses used to use old-fashioned aluminum alloy doors and windows. When they were installed, they were all connected with the wall with fixed pieces, and then filled and smoothed with waterproof mortar. Therefore, the fixed pieces were buried in the wall at least one centimeter, and the fixed pieces were relatively long. The correct way is to cut off the connecting part between the fixed piece and the wall, and then remove the window. If it is forcibly removed, the fixed piece will collapse the waterproof mortar and mosaic of the window sill of the external wall together, which will damage the original waterproof. If it is not repaired in time, the aluminum alloy window may leak after installation.
