I seem to be struggling to source 45 KG / m3 or greater acoustic insulation in Australia.
A lot of the search results I'm finding are out of date.

I hear some materials in the country have a bad smell when used.. I think these are fibreglass type.

As far as I can tell I'm after a high density 45 KG / m3 or higher stone wool product for wood frame void filling.

Any help on types and current sources in Australia appreciated .

If you use fiberglass insulation instead, it would only need to be around 30 kg/m3. The higher density figure only applies to mineral wool insulation. Not sure if that helps!

That does.. help a lot. Many thanks

The cost of this kind of insulation varies greatly from one supplier to the next in Australia, so I suggest you read this similar topic: http://www.johnlsayers.com/phpBB2/viewt ... =2&t=20453
