First, the overall stiffness of the door and window frame
(1) Phenomenon Pushing or opening or closing doors or windows or encountering windy weather, the door and window frames are shaking.
(2) Causes 1. The profile is not properly selected, the section is small, and the strength is not sufficient (according to the standard, aluminum alloy profiles with a thickness of less than 1.2 mm shall not be used for sealing balconies). The prevention of aluminum alloy door and window materials does not meet the requirements. Plastic steel door and window material quality failed. 2. The steel lining steel doors and windows configuration does not meet the standards, the steel wall is thin, the strength is poor; the lining steel is inserted in sections, the shape does not form a strengthening effect; the lining steel and plastic profiles are not firmly connected. 3. The installation node is not in accordance with the specification. 4. There are no different fixing methods depending on the different walls.
(III) Measures 1. The specification and quantity of the profile of the window and door frame conform to the national standard. The thickness of the outer frame of the aluminum alloy profile shall not be less than 2.4 mm. Plastic window material thickness should not be less than 2.5 mm. 2. Check the appearance of plastic profiles. Qualified profiles should be white or ivory white, clean and smooth. Better quality protective film. 3. According to the size of the doors and windows and the installation height, choose the cross-section of the profile. The casement window is not less than 55 series, and the sliding window is not less than 75 series. 4. In strict accordance with the provisions of the provisions of the installation, to ensure solid and stable.
Second, door and window leakage
(I) Phenomenon 1. Leakage between the door frame and the surrounding wall.
2. Sliding window The water in the slide tank penetrates into the window.
(B) Causes 1. Door and window frames and walls are cemented with cement mortar. 2. The gap between the window frame and the wall is not strict and there is a gap. 3. The doors and windows are not qualified, and the combination of window frames and sashes is not strict. 4. The sash seal is not installed and the water seeps through the window sash. 5. The window frame has no drainage holes.
(III) Measures 1. Doors, windows and walls shall not be caulked with cement mortar. Should be flexible connection, sealed with sealant, no gaps. 2. Check whether the doors and windows are qualified before installation, whether the combination between the window frame and the sash is strict, and whether the sealing of the window sash is qualified. 3. There is more than 50 mm gap between the window frame and the hole to enable the window sill to be a water flow slope.
4. Drain holes should be drilled in the bottom frame of the frame and the track root.
Third, the color difference between doors and windows
(a) Phenomenon: The colors of adjacent windows, doors or windows and windows are inconsistent.
(b) Cause The material is not the same factory product, or the same batch of products, or products of different material grades.
(3) Measures 1. The same manufacturer's products should be used for the selected profiles, and they should be prepared at one time. 2. Pay attention to the color of ingredients before cutting, and avoid using materials with large color difference in the same door and window.
