Rolled Wool Prime, also known as Rockprime or Rockwool, is made from volcanic rock which gives it a great density. These characteristics makes it a superb material for insulation sound and fire control. Rockprime or rock wool insulation has a much higher density than fiber glass wool which means it will last longer and perform better. Rock wool insulation s density is 21kg/m3 and its thermal conductivity is 0.047W/mk, Rock wool performs better and last longer which in turn means it will save you more money and make your home more comfortable.
