more on my noisy neighbour project...
I've put down sheets of 100mm thick dense fibre matting between my floor joists - this may keep my flat warm but I am far more interested in achieving acoustic insulation not thermal insulation - all due to noisy lord fauntleroy downstairs and his stereo.
My problem is there is one joist cavity running along the length of my flat that is very inaccessible i.e. I cannot get lay down my soundproofing material into the void.
I read somewhere that sand is sometimes used to achieve acoustic insulation.
For flats like mine where some joist voids are inaccessible ( due to pipes/noggins/stud partitions etc ) is it feasible/sensible to pour dry sand down between the floor joists. This would only be for one joist void ( approx dimensions 100mm high x 300mm wide x 4 metres long ).
Any thoughts welcome.
