After the doors and windows are installed, various problems will inevitably occur. Therefore, the editor has sorted out common problems and corresponding solutions.
Color difference between doors and windows:
1. Phenomenon: the adjacent doors and windows or window frames are inconsistent with the color of the fan.
2. Reason: the material is not the same factory product, or the same batch of products, or products of different material grades.
3. Measures: when purchasing profiles, the products of the same manufacturer should be used and sufficient materials should be prepared at a time. Pay attention to the color of ingredients before blanking to avoid using materials with large color difference on the same doors and windows.
Door and window leakage
1. Phenomenon: leakage at the junction of the door and window frame and the surrounding wall. Accumulate water within sliding window under sliding chute and penetrate into the window.
2. Reason: door and window frame and for walls cement mortar caulking. The glue injection between the door and window frame and the wall is not strict and there is a gap. The door and window technology is not qualified, and the combination between the window frame and Casement is not strict. Casement the sealing strip is not installed properly, and water seeps into the Casement glass seam. The window frame has no drainage hole.
3. Measures: doors, windows and walls shall not be caulked with cement mortar. It should be connected elastically and sealed with sealant, without gaps. Before installation, check whether the doors and windows are qualified, whether the combination between the window frame and the Casement is strict, and whether the installation of the sealing strip is qualified. There is a gap of more than 50mm between the window frame and the hole, so that the window sill can make a running slope. Drain holes shall be drilled for the lower frame and track root of the outer frame.
The overall stiffness of the door and window frame is poor
1. Phenomenon: sliding or opening and closing doors and windows or in windy weather, the door and window frames shake.
2. Reason: D profile selection is improper, section is small, insufficient rigidity. The prevention of aluminum alloy door and window materials does not meet the requirements. The quality of plastic steel door and window materials is unqualified. @ The steel lining configuration of plastic steel doors and windows does not meet the standard, (generally, 1.20 is used for steel lining, but the owner cannot see it because it is installed. Many merchants use unqualified ones to install them to the owners) the strength of steel wall hail is poor; The lining steel is inserted in sections, and the shape cannot be strengthened as a whole; The lining steel is not firmly connected with plastic profiles, etc. The National installation node is not in accordance with the specifications. @ Different fixing methods are not adopted according to different walls.
3. Measures: the specifications and quantity of door and window frame profiles meet the national standards. The outer frame wall thickness of aluminum alloy profiles shall not be less than 2.4mm. The thickness of plastic steel window material shall not be less than 2.5mm. Check the appearance of plastic profiles. Qualified profiles should be bluish-white or ivory white, clean and smooth. Good quality should have protective film. According to the opening size and installation height of doors and windows, China chooses profile section, with casement window not less than 55 series and sliding window not less than 75 series. Install in strict accordance with specifications to ensure firm and stable.
