Aluminum alloy doors and windows are generally directly used for thermal insulation and broken bridge aluminum profiles and hollow glass, so it has the functions of energy saving, sound insulation, noise prevention, dustproof and waterproof. However, to take full advantage of Aluminum alloy doors and windows, it is necessary to consider the comprehensive results of the performance of equipment, profiles, accessories, glass, viscose, and sealing parts. All of them are indispensable to form high-performance system doors and windows. The phenomenon of water leakage is generally due to the fact that water seepage sites close doors and windows and doors and windows are often mistaken for leakage.
The gap between Aluminum alloy doors and windows and the wall of the opening cannot be filled with qualified materials as required, such as waterproof cement mortar with different markings or disproportionate proportions..
The fixed connection of perforated doors and windows is not strong, so that the doors and windows move under the action of wind load, which will cause cracks in the sealing material. The filling material does not cover the gap between the door frame and wall, cracks and valleys phenomenon.
Whether the adjustment control pads of the fixed door and window frames are left in the door and window frames, or there is no further research for secondary filling after removal.
After the installation of Aluminum alloy doors and windows, we did not analyze and seal the different parts of the connection between the outside of the doors and windows and the wall, or the seal failed.
