The reasons may be:
1, the sliding bearings are not installed in place, indicating that the sliding bearings on both sides are not in a line;
2. The screws installed in sliding supports are not suitable, and the screws fight with sliding supports;
3. The size of the selected sliding supports is too small to bear the weight of the window sash;
4, the glass mat is not in place, the window sash ceiling fan!
5. "After the casement window is closed, the fan material and frame material on the handle are uneven, and one side of the sliding support is flat." This requires adjusting the snap points.
Advantages of translation window:
1. Reduce heat conduction: heat insulation broken bridge aluminum alloy profile is adopted, and the thermal conductivity 1.8 ~ 3.5 W/㎡ k is much lower than that of ordinary aluminum alloy profile. 2. Anti-condensation: the temperature of the inner surface of the profile with heat insulation strip is close to the indoor temperature, which reduces the possibility of condensation on the profile surface due to oversaturation. 3. Waterproof function. Based on the principle of pressure balance, a structured drainage system is designed, and the downward slope is designed as a ladder with a drain, which is smooth and watertight. 4. Anti-theft and anti-loosening device. Equipped with a unique multi-point hardware lock to ensure the stability of the window in use.
