In winter, we usually close the window at home to prevent the wind from entering the room to keep the indoor temperature. However, some people worry that the difference between outdoor temperature and indoor temperature is huge, will it easily cause thermal expansion and contraction of doors and windows?
The answer is no. The reason for the thermal expansion and cold contraction of doors and windows is that the expansion phenomenon may occur in door and window rubber strip. The sealant strip cannot be pulled hard and should be in a natural state to ensure the sealing performance of doors and windows. In addition, sealant strips and wool tops of aluminum alloy doors and windows should be repaired or replaced in time when they are damaged, aged or shortened.
In addition to the above measures, we should pay attention to the following big points in normal days to avoid thermal expansion and contraction of doors and windows.
1. If the temperature difference between doors and windows is very large, it is very likely that the bridge will be deformed due to the temperature difference. It is recommended to add a Expansion joint at the elbow of the bridge.
2. Doors and windows should be checked regularly to check whether the drainage system of doors and windows has bulkhead and clear bulkhead. Keep the drain open. Regularly clean the sliding rails, slides and other positions of doors and windows to avoid dust accumulation affecting door and window switch.
3. Regularly check the hardware accessories of doors and windows, whether the screws of doors and windows are loose, etc. to ensure that the screws are intact. Check whether the casement of doors and windows, handles, hinges and other hardware accessories are damaged or deformed.
4. Aluminum alloy doors and windows should be cleaned with neutral water-soluble detergent, and corrosive chemicals such as acetone and xylene should not be used to clean doors and windows.
