SOUND STOPPER ACOUSTIC PANEL Avoiding the problems of sound coming through walls is one huge hassle. Constructing a plasterboard wall a few inches in front of the existing wall and filling the void with Rockwool is the traditional method. That in turn may partially resolve the problem but in turn create many further issues such as builders, cost, disruption, down time etc. Hi Tech industry had licked the problem years ago by applying a sandwich of foam, lead sheeting and foam. The foam attached to the wall acts as a decoupler whilst the sheer density of the lead sheet is an immovable object resisting the movement of air (sound waves) This method far outperforms attaching lead directly to a wall, is simple, not intrusive and costs substantially less. Due to the numerous problems with lead sheet a composite material was developed which has the same density and an identical acoustic resilience as lead. On either side of this composite material is 6mm of a very high density foam. One side is in contact with the wall, the other side exposed to the room. Normal acoustic tiles have a density of around 28 - 40 kg/cubic metre, this foam is 75kg/cubic metre. This combination yields an A weighted transmitted noise reduction of 27dB. Available in tile form 2000mm x 1200mm and 14mm thick. Weight 16kg. Colour Black. An information sheet provides easy fixing suggestions.
