[0002] Accurate measurement of interior wall thickness is one of the key steps to ensure that building quality meets standards. The thickness of the interior wall is closely related to the thermal insulation performance of the building. Appropriate interior wall thickness can effectively reduce the conduction of indoor and outdoor temperatures and improve the energy-saving effect of the building. The thicker the interior wall, the better the sound insulation effect. This is especially important for residential buildings, as it can effectively reduce the impact of noise on residents and improve living comfort.
