From what I can gather blown insulation isn't common practice anymore, but I did come across granulated rockwool from Bradford - http://www.bradfordinsulation.com.au/Pr ... -Fine.aspx It's a commercial product that would be more costly, but Bradford only had 3 x 12.5 kgs bags in stock and 6-8 week lead time. After speaking with their insulation department for possible installers, they effectively said you can't do blown insulation into a subfloor. I gather you can't get a consistent uniform layer by simply pushing the hose around through the posi-struts. They suggested the only way to do it correctly would be to remove plaster and install soundscreen batts as original intended. Obviously the better solution would be to also install heavier plasterboard like Gyprock Soundchek - http://www.gyprock.com.au/oursolutions/ ... tions.aspx I spoke with the builder and asked them to remove the plaster and install rockwool batts, so we'll see how we go.
