Aluminum-clad wooden windows have the functions of energy saving, sound insulation, noise prevention, dustproof and waterproof. Nowadays, aluminum-clad wooden windows are generally used in home decoration. The installation quality of aluminum-clad wooden windows has a great influence on the later use and lifespan. Therefore, when the doors and windows are installed, we need to check the appearance, profiles, hardware, and opening and closing of the doors and windows. If you have any problems after installing the doors and windows of your house, you may wish to check whether the installation is improper. How to check it? Need to start inspection from the following aspects:
1. Inspection of aluminum-clad wooden window sash
The surface quality of aluminum-clad wooden windows directly affects the decorative effect of the entire wall after installation. The visual inspection of aluminum-clad wooden windows includes whether there are cracks on the surface, whether there is deformation, and the installation inspection of window rubber strips. The following is the specific inspection operation :
1. Appearance inspection of aluminum-clad wooden windows
Look at the glossiness of the aluminum-clad wooden window and whether there are obvious color unevenness on the surface. Then use a ruler to measure whether the diagonal lines of the doors and windows are the same, and look closely for scratches.
2. Seal inspection
The contact between the sealant and the glass and the glass notch should be smooth, and the sealing strip must not be crimped or detached. There should be no obvious gap between the bead and the profile, and the joint gap should be less than 1mm.
Two, aluminum alloy door and window lock inspection

In the inspection of door and window locks, first check whether the installation position of the door and window lock is correct and whether it is installed reversely; secondly, whether the two sides of the lock are installed correspondingly and whether there is any misalignment; then shake the door and window lock by hand to see if there is any looseness.
2. Check the use of door and window locks
Check the flexibility of the door lock movement and whether the unlocking and unlocking actions can be carried out smoothly; then check the window, close the window lock, push the moving window by hand, and check whether the window can be locked without moving.

The installation of the door and window frame directly affects the firmness of the entire door and window. The inspection of the door and window frame can be checked from its firmness, flatness, and tightness.
1. Check the vertical flatness of the frame
Use an infrared level to check the verticality range of the door and window frame. Generally, the allowable deviation of the front and side verticality of the door and window frame is 2.5mm, the horizontal allowable deviation of the horizontal frame of the door and window is 2mm, the allowable deviation of the horizontal frame of the door and window is 5mm, and the vertical deviation of the door and window is off the center. The allowable deviation is 5mm.
