First, the reason for the sound of the ceiling at night
1. The ceiling is not installed flat
Check whether the ceiling is installed smoothly and whether there is a depression. If there is, it may be caused by this reason that the ceiling has a sound. At this time, you can ask someone to reinstall it. In addition, it may be that the ceiling material is not good enough, after a long time, there are problems such as cracking.
2, wood keel deformation
It may be due to the high indoor humidity, resulting in the deformation of the wooden keel, causing the ceiling to have a sound, so when designing the ceiling, pay attention to the expansion joint of the ceiling, so as to effectively avoid the ceiling from making a sound.
3. The roof is close to the heat source
Thermal expansion and cold contraction will also lead to the sound of the ceiling, the sun shines during the day, the roof expands, and at night, the temperature drops, causing the thermal expansion and cold contraction of the ceiling, so the ceiling has a sound at night.
Second, precautions for ceiling removal
1, when dismantling, try to remove all the original ceiling decorations, especially the boom, pendants and other objects, must be removed clean, so that the subsequent installation of the ceiling is more convenient and safer.
2, before removing the ceiling, first cut off the power supply, and when removing, remove all the original old circuit, the subsequent operation will be safer.
3, if the ceiling is installed inside the heating pipe or air conditioning system, then remove the ceiling, try not to damage these, if damaged later maintenance is very troublesome.
4, when removing the kitchen and bathroom ceiling, pay attention to try not to damage the air duct and flue.
5, after the removal of the ceiling, pay attention to ensure the integrity of the ceiling as far as possible, and the subsequent recycling is more valuable to reduce their economic losses.
