There are many different materials that can be used for soundproofing - each with its own particular benefits, properties and applications. Find out what sorts of materials are useful where, and how effective they're likely to be.
Barrier boards, also known as acoustic boards, are specially designed boards that feature two outer layers sandwiching a sound absorbing material. They are a cost effective way to control noise through walls.
Purpose-built plasterboard products allow for a far greater amount of soundproofing and noise reduction than conventional plasterboard. Soundproofing plasterboard is also relatively inexpensive, and easily installed.
Acoustic underlays sit underneath floor coverings to prevent sound from being carried through to the floor below. They also help to reduce heat transmission, and make your floor softer to walk on.
Soundproofing glues are special glues that are used to prevent sound from travelling between layers of more rigid materials. Soundproofing glue, when applied correctly, is especially good for reducing bass noise.
Cellulose insulation is made from plant fibres, and is used to insulate wall and roof cavities. Cellulose insulation does an excellent job of controlling heat at a good price, and is highly versatile.
Glass wool is made from fibreglass, and is available either as rolls of insulation, or as batts or blanketing. Glass wool is relatively inexpensive, and as a result it's sometimes layered for improved insulating performance.
Also known as 'mineral wool', this type of insulation is made from rock spun into thin strands and then bound together. It's normally sold in rolls or batts, is inexpensive, and is relatively effective and easy to install.
The ability of sheep's wool insulation to provide effective soundproofing comes down to how thick it is. Find out more about how sheep's wool insulation can be used for soundproofing.
In the right form and circumstances, polyurethane foam insulation can work well as a soundproofing material - particularly for muting midrange noises like music and voices.
