Stone wool is one of the best thermal insulators on the market today. In terms of technical performance, the thermal conductivity is between 0.042W / mK to 0.033W / mK. The thermal resistance is between 2.35 m2 K / W and 3 m2K / W.
Advantage N ° 2: The additional sound insulation
Rock wool is an excellent thermal insulator. It is also an excellent sound insulator which helps to combat noise pollution. A very useful double functionality, especially since rock wool can be placed on walls, floors and ceilings.
Advantage N ° 3: Several packaging
