Will be decorating my Living room soon. The decorating and all other other items, settee, units etc will be centred around my 5.1 set-up. Have decided to use tongue and groove wood cladding/panelling to cover the lower part of the room. This will give me roughly 1" of free space between the wall and the panelling. I will be using this space to cover unsightly wires; speaker cable, extensions etc. While thinking about this I realised that i could also use this space to "Sound insulate" the lower part of the living room. Does anyone know of a cheap proffessional or DIY material that i could use that is flexible enough to go around the wires and the battening? Any suggestions would be appreciated.
