Soundboard

Soundboard

Marmox Soundboards have been designed to offer impact sound reduction as a result of foot fall on tiled floors.

Impact sound reduction (on a tiled floor)

Impact sound is the type of noise Marmox SoundBoard was designed to reduce. The SoundBoard effectively removes the solid link between where the impact happens (i.e. the footfall on the tile) and the ceiling by placing a layer of rubber foam between, so the sound waves do not have a medium to pass through. This delivers a significant improvement in acoustic insulation.

An increasing proportion of buildings and residential dwellings encounter problems related to noise. In addition, as we create more multi-occupancy buildings within our cities and towns, the issue of controlling sound through building design and construction is crucial.

Marmox sound reduction solutions for floors help architects, developers and contractors to achieve compliance with the requirements of Part E of the Building Regulations. In England, Wales, Ireland or section 5 of the Scottish Building Standards, both relate to the resistance to the passage of sound within a property. These include the requirements for sound insulation in both new dwellings and dwellings-houses and flats formed by material change of use.

Noise on tiled floors

Ceramic tiles on floors can make noises such as footsteps sound even louder in the room below. Many local authorities do not allow tiled bathrooms in shared accommodation for this very reason.

Marmox SoundBoard enables floors to be tiled without the danger of causing noise pollution to the people in the room or flat below. This soundproof insulation product is available in two thicknesses: 8mm and 12mm. While both thicknesses contribute a sound reduction of approximately 20dB, the difference between them is that the 12mm board provides more thermal insulation than the 8mm version.

Marmox SoundBoard is much more than just an impact sound reduction layer - it also provides decoupling so that lateral movement in the floor is absorbed by the board and not by the tiles so the tiles don’t crack. It is completely waterproof and, as well as improving acoustic insulation, helps to lock in heat in rooms where it's fitted.

How to install SoundBoard

The first step is to fix the boards, rubber-side down, to the floor. Use either a thin bed of flexible tile adhesive or Marmox MSP360. MSP360 absorbs sound waves, thereby offering slightly more sound reduction and insulation than just using the boards on their own.

Irrespective of which adhesion method is used, a gap of about 4mm should be left between the edge of the boards and the wall, which is then filled with a visco-elastic adhesive such as Multibond to eliminate the possibility of flanking sound happening there.

After you have installed our sound proof insulation and absorption products, tape over the joints and tile as normal.
