    We are building a new house at the moment. The builder has the second floor in. Can anyone give a recomendation on the best form of sound proofing on the floor. I heard there is some sort of rubber mat that can be put down on the chipboard but can't find any info on the net.

    Any help would be appreciated.

    you didn't look very hard:)

    the best job for soundproofing is one of the proprietary systems that separate joists and ply/floor. the next best thing is to glue and screw ply to joists and use deadening layer as you describe. i have used cork in the past and it works ok, there's also wood fibre or a wool type underlay as well as actual screeds and then there's placing insulation between the joists..etc.. and im sure there's plenty of other options.

    Goggle 'acoustic flooring' and any of the key words I mention above

    It's like anything else, depends on the performance you require & the amount of money you want to spend. As stated above there are systems from a number of manufacturers which involve accousticaly seperating the floor from the joists & also suspending the ceiling on special hangers which if I remember correctly are a couple of euro each just for the brackets. Then you have the metal suspended ceiling below these. I have fitted these

    The simplest & probably cheapest solution is to just lay cork above the plywood / T & G and then the floor covering. There are products made specifically for this. I've also fitted this

    PM me if you need product names or any other help as I don't think we're allowed mention specific products on here.

    Hi agri contractor
    I put rubber carpet underlay on joists with stapler. Then plywood on floor screwed down with a 2mm expansion between sheets for expansion. I then used a foil backed flooring underlay.Then fitted finished floor, Put 200mm rockwool between joists. Customer was very happy with the work.
