Marmox Sound Reduction Board

[actionjackson]

Has anyone got any experiences with this new tilebacker board from Marmox? It incorporates a rubber foam layer to assist with conformity with Part E building regs (impact sound).

I'm about to plan a bathroom project in a 7yr old 1st floor flat, which was tiled on top of a floating acoustic layer (tiles cracked due to movement). The entire sub floor will be replaced with marine ply, but I need to preserve the acoustic properties as best as possible so am looking for suitable sub-floor solutions for UFH & tiling.

Another question regarding sub flooring, for tiling purposes does a floor with multiple layers potentially offer improved rigidity over a sub-floor with one thick layer? The reason i ask is this bathroom has multiple layers totalling nearly 60mm which i need to get back to, to be level with adjacent rooms.

Cheers
Neil

Can't comment on the product you have mentioned, but I have installed and tiled similar to this a few years ago: http://www.insulationexpress.co.uk/Acoustic-Insulation/Karmafloor-Acoustic-Insulation-Mat.htm

Stick it down with F3 floor adhesive then use flexible adhesive and grout.

With regards to the subfloor, it depends what the man sub floor is. My personal preference is for one rigid subfloor but over the years I have tiled on many different floor types, various types of floating floors, tanking systems etc and not really had any problems. Just make sure you use the correct adhesives for the application. If in doubt contact the manufacturers technical department who will advise you on what product to use.
