SteicoFlex for sound insulation? Is this material suitable as a mineral wool replacement for DIY acoustic panels construction? I'm looking for a healthier alternative for mineral wool and this seems quite promising.
Hi. Yes, the Steicoflex is arguably better than most mineral wools as it is denser and wood fibres are slightly better at absorbing sound energy as well. This product is 60kg/m3 so you'd need a mineral wool of at least that density to improve on the Steicoflex.
For the best sound insulation try using our EBB Clay Boards which have a 52dB reduction for a single sheet on a solid stud wall or 63dB reduction if both sides of the studs are using clay boards.
Hope that helps.
