Marmox SoundBoard Soundproofing Tile Backer Board
Marmox SoundBoard is a soundproofing tile backer board that can be used to reduce impact sound heard in the rooms below. SoundBoard will reduce the level of impact noise greater than the recommended minimum of 17dB. Not only does the board provide effective soundproofing for tiled floors, but it also has many of the benefits of Multiboard including providing a waterproof layer, secure decoupling, thermal insulation and low compressibility.
SoundBoard is coated on one side with a sound attenuating layer of SBR rubber that isolates the tiled surface from the floor so that there is nothing for the sound waves to travel through. The rubber compound used is a natural material so there is no plasticiser migration ensuring the material neither shrinks, degrades or becomes brittle.

Marmox SoundBoard Installation
Firstly, fix the boards with the rubber coated side facing downwards using a thin bed of either flexible tile adhesive or Marmox Multibond. Multibond itself is a visco-elastic material so absorbs sound waves thereby offering slightly more sound reduction than just using the boards on their own, however it will take 12 hours to cure sufficiently to tile onto. Ensure that you leave a gap of 4mm between the edge of the boards and the wall, which is then filled with Multibond to eliminate the possibility of flanking sound happening there. After you have installed our SoundBoard, tape over the joints and tile as normal.
Marmox SoundBoard measures 1200x600mm and is available in 8mm or 12mm thicknesses.
