What level of sound reduction should I expect from adding 2 x layers directly to an existing brick party wall?
Due to limited space (~28mm) between the wall and window, I don't have the option of using resiliant bar or building a room within a room etc.
If I add 2 x layers of Soundshield board directly to the wall, what level of sound attenuation would I expect?
Also, could I simply bond these boards to the wall using 'No More Nails' or similar? The wall already has a layer of plasterboard, skimmed over, I believe.
