Acoustic Insulation Opening Detail With Rock Wool Partition Wall

This AutoCAD drawing presents detailed acoustic insulation construction used at wall openings and partition connections within interior building spaces. The drawing illustrates the structural composition of an acoustic partition system designed to reduce sound transmission between rooms while maintaining thermal insulation performance. The wall assembly begins with the existing plastered structural support surface, followed by an elastic acoustic base layer that improves vibration isolation between structural elements. Vertical metal mounting profiles are arranged with a spacing of 46 by 70 millimeters, forming the internal structural frame for the acoustic partition wall system. Inside the partition frame, mineral rock wool insulation panels with a density of approximately 70 kilograms per cubic meter are installed to absorb airborne sound and improve acoustic performance.
