The soundproofing system shown is extremely effective. It involves building a new stud wall, 100mm thick, 50mm inside the existing wall of the room, and so does mean that the room loses 150 to 200mm from its original size per wall soundproofed. Where the sound problem is less severe, or space is at a premium, there are simpler systems available - contact us for details.
A stud wall is built 50mm inside the existing wall, and filled with acoustic insulation material. Where possible floor and ceiling cavities should be filled with acoustic insulation material as well.
The wall is covered in acoustic matting and metal resilient bars are fitted ready to receive the plasterboard. The slight flexibility of the bars reduces vibration transmission.
Two layers of acoustic-rated plasterboard are then fixed to the resilient bars, and any small gaps around the edges filled. The wall is then ready for skimming as usual.
