    Hi
    Any of you guys fitted carpet and vinyl over this stuff....http://www.ccfltd.co.uk/wrms/Acoustic_Impactalay_Plus.pdf
    Got 3 flats and communal areas to do the builders are laying these down fully bonded to floor,company says they have to fit right up to edge of skirtings and to stick gripper on top, cant see that will be solid enough for stretching ??
    Some vinyl to lay too, on the website it says overlay with 6mm ply, but how that gonna be fixed satisfactory, any links or tips would be great
    Cheers

    you cant do what they say.

    Either a batten around edge needs to be installed or you need to install on a twin stick.

    As for vinyl, you can glue the plywood to it. Personally im not happy with this and neither are a lot of others. A system like mapalay isolator or jumpax etc should be laid over the top.

    Fitted Over this stuff acouple of times they should put a timber baton around the perimeter to put gripper onto then it acts as an underlay

    I've fitted over that a few times, wouldn't fancy trying to stick gripper to it. We built up the gripper round the edge. Don't like the idea of screwing 6mm ply over it either! Jumpax sounds good to me. One builder made us put the domestic vinyl straight on to it. His mrs was looking round it a few weeks later and put her high heels straight thru it!

    you cant pin/nail etc through it. You can only bond or loose lay above it.

    Reason being is if you was to screw or nail through it then it DB rating will be lost. Noise travels through fixtures like screws etc.

    Oh yeah, that's why the chipboard floors are floated not screwed der. Well sod trying to glue ply to it, it would be all over the place.

    Batten sound better if I stick it, then its going to be an expensive job for them when the carpet wears, i,ve never used jumpax, is that like the mflor floating floor ? and are you suggesting that to be floated or stuck on to the acoustaly

    similar to Mflor product. However its not actually a mflor product but a product made by a company called 'smart floor' that mflor recommend.

    it is a loose lay system.

    Going back to the carpet, a company called instalay do a floating underlay system for carpet and vinyl.

    Battens seem to be the way for the carpet, regarding the vinyl, still not 100% sure, had a look at the instalay, probably less time consuming than the jumpax......depends on which one will do the better job
