Browse Forums Renovation + Home Improvement 1 Oct 28, 2015 4:21 am Hi We are renovating dowstairs of our house and very worried about the sound insulation the gyprockers put. The builder totally forgot about telling gyprockers that sound insulation was to go in and luckily as we were downstairs we stopped gyprockers doing further work. The gyprockers rushed to buy the insulation from bunnings. I only saw whatever they bought at the end of their job as one part of ceiling was open. It was very thin, maybe 1cm white and blue looking wool. I also saw it was rolled up in a cylinder shape and unfortunately didnt see the package. Does anyone know what this is? At that time i was wondering how would such a thin layer of that soundproof the 2 floors so asked gyprocker to put 2 layers. He was chinese and didnt know a word of english unfortunately. Our builder(whom we had so many issues with, very forgetful and not trustworthy in his work) arrived then so asked about it and he said putting two layers doesnt mean more sound insulation. At the time i didnt even know there was rating for different insulation so believed him. i think he should have asked what rating was needed at least. I have done a google search for hours and cant find out what it is they put in. Most are thick acoustic batts which is yellow or brown. I wouldnt care if it was thin or white if it actually works but it is no different from not having it. From downstairs, you can hear talking, people walking upstairs which is more like stomping noises....ahhh!!!! They have finished gyprocking and tiling the floors now. I dont know if i have to rip up the ceiling gyprock which will probably damage timber framing and start again and this will delay another week. They are over by 2.5 weeks already. Anybody able to help me? We are soo stressed with the whole reno meeting the wrong builder.... TIA Re: Sound insulation between two floors (timber) 2Oct 28, 2015 8:23 am Hi Maz80 I hear similar complaints all too often and unfortunately with acoustic soundproofing there is not much you can do except pull it down and redo it properly (at your own expense you should have specified a rating for Sound level pressure (dB) and acoustic pressure (Pa)), see if your builder will provide you with some financial/labour assistance? What I recommend is acoustics board on top of the plaster board ceiling fixed to the floor joists and sound insulation between the ceiling joists. You might want to contact the manufacturers for their recommendations and alternate solutions,etc. My detail solution is here: https://plus.google.com/u/2/114544938995916531570/posts I cant stress enough how important it is to get Professional expert advice (on Acoustic Engineering) always ask for proofs, calculation or simulations before you accept a designers/builders/contractors solution Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Sorry, don't know costs, but there are a couple of very important principles you need to get right (and now) ....
