With a density over three times that of fiberglass, mineral wool has superior sound-deadening properties. Both products retain heat, so they are used for thermal insulation, promoting a cool environment in summer and a warm one in winter. Although there are some insulators out there (particularly cellulose) that are susceptible to igniting, both Rockwool and fiberglass have great fire resistance as both are non-combustible. Fiberglass, on the other hand, blocks ~ 4 to 10 decibels. Fiberglass costs around $0.50 per square foot ($5 per square meter). While this article focuses mainly on sound insulation, I think that its extremely important to address if these materials can be considered a fire hazard or not, which is determined by the flame spread index. 28.
