Aluminum alloy doors and windows is a set of overall system, the need for interlocking construction convergence and multi-party close cooperation, design rigorous, reasonable in order to make its sealing good. In the long-term use of aluminum alloy doors and windows, there is no lack of door and window leakage phenomenon, so what is the cause of the leakage phenomenon in the installation of aluminum alloy doors and windows? Today, Kemet Aluminum summarizes the following five reasons for you: 1. The selection of profiles and node structure are not suitable. The design of aluminum alloy doors and windows is not strictly checked in accordance with the design specifications of aluminum alloy doors and windows. Plane splicing is adopted for the node, and the gap at the flat seam is too large. The plane rigidity of the rear window is extremely poor. Under the action of hand push and wind pressure, there is an obvious sense of shaking, causing deformation between the frame and the wall and the joint of the profile, poor tightness, and rainwater entering through the gap, causing leakage. This situation is more common in the installation of the combination bar. The material selection of the lower frame is too small, the cross-sectional size does not meet the standard regulations, and it is not raised according to the regulations. Some even bury the window frame into the window sill plastering layer, causing rainwater to penetrate into the room easily. 2. Improper connection between the outer frame of doors and windows and the wall The connection between the outer frame of aluminum alloy doors and windows and the wall is the key to its firmness and reliability. If the connection is improperly fixed, it will cause looseness, deformation and cracks. 3. Improper injection of sealant The gap between the aluminum alloy door and window frame and the hole shall be sealed with sealant. At present, many construction units do not leave notches when injecting sealant. The sealant is applied at the negative corners, and the window sill is applied on the same profile plane of the plastering layer. The width and thickness of the sealant are difficult to control. When injecting glue, the surface is not cleaned, the bonding is not firm, the glue injection is not continuous, and the formed tape is easy to fall off and cannot play a sealing role. 4. The construction specification for sealing the profile without glue requires that when aluminum alloy profiles are combined horizontally and vertically, sleeve insertion shall be adopted, the lap length shall be 10mm, and sealant shall be used for sealing. In the actual construction, when the profile is combined, the leakage of sealant is more common. For example, in the window sash, window frame cutting angle splice, open screw connection, rubber strip disconnection, are not take a reliable and effective seal, the formation of water seepage channel. 5, the window frame lower sill drainage hole set unreasonable aluminum alloy window lower sill drainage hole should be able to ensure the smooth drainage of water in the tank. In some construction units, no matter how big the window is, only one hole is opened. The hole diameter is too small to be blocked, resulting in accumulated water in the tank, especially when the accumulated water in the sliding window tank cannot be discharged smoothly, under the action of wind pressure, the inner tank will turn over and even blow rainwater into the room.

aluminum alloy doors and windows is a set of overall system, the need for interlocking construction convergence and multi-party close cooperation, design rigorous, reasonable in order to make its sealing good. In the long-term use of aluminum alloy doors and windows, there is no lack of leakage of doors and windows, so what is the cause of the leakage of aluminum alloy doors and windows? Today, kemite aluminum industry has summarized the following five reasons for you:
1, inappropriate profile selection and node structure
when designing aluminum alloy doors and windows, it did not strictly follow the design specifications of aluminum alloy doors and windows for checking calculation, inappropriate profile selection, small profile section size and too thin material. Plane splicing is adopted for the node, and the gap at the flat seam is too large. The plane rigidity of the rear window is extremely poor. Under the action of hand push and wind pressure, there is an obvious sense of shaking, causing deformation between the frame and the wall and the joint of the profile, poor tightness, and rainwater entering through the gap, causing leakage. This situation is more common in the installation of the combination bar. The material selection of the lower frame is too small, the cross-sectional size does not meet the standard regulations, and it is not raised according to the regulations. Some even bury the window frame into the window sill plastering layer, causing rainwater to penetrate into the room easily.
2. Improper connection and fixation between the outer frame of doors and windows and the wall
The connection between the outer frame of aluminum alloy doors and windows and the wall is the key to its firm and reliable fixation. If the connection is improper, it will cause looseness, deformation and cracks.
3. Improper injection of sealant
The gap between the aluminum alloy door and window frame and the hole shall be sealed with sealant. At present, many construction units do not leave notches when injecting sealant. The sealant is applied at the negative corners, and the window sill is applied on the same profile plane of the plastering layer. The width and thickness of the sealant are difficult to control. When injecting glue, the surface is not cleaned, the bonding is not firm, the glue injection is not continuous, and the formed tape is easy to fall off and cannot play a sealing role.
4, profile seal without glue seal
construction specifications require aluminum alloy profiles in the horizontal vertical combination, should adopt sleeve, lap length should be 10mm, and seal with sealant. In the actual construction, when the profile is combined, the leakage of sealant is more common. For example, in the window sash, window frame cutting angle splice, open screw connection, rubber strip disconnection, are not take a reliable and effective seal, the formation of water seepage channel.
5. The drainage hole of the lower sill of the window frame is unreasonable. The drainage hole of the lower sill of the
aluminum alloy window should be able to ensure the smooth drainage of accumulated water in the tank. In some construction units, no matter how big the window is, only one hole is opened. The hole diameter is too small to be blocked, resulting in accumulated water in the tank, especially when the accumulated water in the sliding window tank cannot be discharged smoothly, under the action of wind pressure, the inner tank will turn over and even blow rainwater into the room.
