Frequently Asked Questions
Which mineral wool should I choose for soundproofing?
For soundproofing, ROCKWOOL Safe 'n' Sound is the standout pick (4.7 rating). It is a high-density (about 2.5 lb/ft3 in 3-inch batts) stone wool batt made for interior walls, floors and ceilings, combining strong sound absorption with a melting point above 1,177C (2,150F) so it is non-combustible.
Does ROCKWOOL Safe 'n' Sound have an R-value for code compliance?
No. ROCKWOOL does not publish an R-value for Safe 'n' Sound, because it is a sound-control and fire batt for interior partitions, not a thermal batt. Its data sheet lists acoustic data (NRC 1.10 at 3 in, 1.25 at 6 in) and fire performance (flame spread 0, smoke developed 0), but no R-value. If you need a rated R-value for an exterior wall or an insulation code requirement, use Comfortbatt instead, which is sold by R-value (R-15 at 3-1/2 in for 2x4 walls).
Does ROCKWOOL Comfortbatt R-15 fit standard stud spaces?
ROCKWOOL Comfortbatt R-15 is a 3-1/2-inch stone wool batt sized to friction-fit standard 2x4 (16-inch on-centre) wood stud walls, which minimizes gaps and air leakage. It is rated R-15, water- and moisture-resistant, and non-combustible, with a 4.5 rating.
