Looking on how to soundproof your boardroom, residential house, classes, conference halls, studios etc? Worry no more Kingsman Industrial Insulation are ready to sort you out with both materials and services in Kenya.
1) Rolls of building Insulation
As expected building insulation is a very good sound absorber at the source of the noise. The thicker and more dense mineral products are superior. Performance can be improved by introducing an air space in the total design of the soundproofing and also by using insulating materials with a lining – where the lining faces the sound source. Building insulation tends to be more effective for soundproofing around the frequency of human voice. The most cost effective thickness for roll insulation is probably 3 1/2 inches or just under 9 centimetres.
2) Batts
As for rolls of building insulation.
3) Rigid fibreglass sheets & ceiling board
Again generally the thicker the board the more effective it is. Probably the most cost-effective thickness for fibreglass board is around 2 inches or 5 cm. Interestingly fibreglass boards with facings seem to perform less well than fibreglass boards without facings. In other words avoid the added expense of faced boards.
4) Form board for roofs
Two to 3 kg density fibreglass form board of only 1 inch thickness is easy to handle and performs very well if you are able to obtain it at a good price.
5) Ceiling boards
Painted perforated and fissured mineral ceiling board is easy to handle and performs reasonably well at around 2 cm thickness. The best soundproofing is achieved with cast rough texture mineral ceiling board. Note: wood fibre ceiling boards do not perform particularly well. Foam sheets/tiles and soundproof foam ceiling boards perform quite well as absorbers when they are one or 2 inches thick. At this thickness they perform almost as well as the mineral ceiling board, but are clearly much easier to handle. Mineral ceiling board probably has better barrier qualities though.
6) Wall panels
For the general principles relating to wall panels see the comments on ceiling boards.
7) Floor coverings
Carpets are only good soundproofers if they are used as absorbers. A lot of their effectiveness comes from reducing impact noise. So for example you might put down carpet mostly to reduce the sound of footsteps on a timber floor and to dampen some of the airborne noise in the room. There are specialised underlays which can be placed beneath carpets or floating floors. These need to be properly selected and you should ask for very clear sound transmission performance data and additional data on impact noise performance.
