Mineral wool, also known as rock wool, has a thermal conductivity that ranges from 0.032 to 0.043 W/mK at the temperature of 24C.
The exact thermal conductivity of mineral wool will depend on the specific product and its density. In general, denser mineral wool products have a lower thermal conductivity and provide better insulation performance.
It’s important to note that the thermal conductivity of mineral wool can be affected by various factors, such as temperature, humidity, and pressure. In high-temperature applications, the thermal conductivity of mineral wool may increase, which can reduce its effectiveness as an insulation material.
