Adequate insulation thickness is crucial

The main task of low-temperature insulation is to prevent condensation. In addition to the quality of the material and workmanship, the correct insulation thickness is decisive in achieving long-term condensation control even under critical conditions. To calculate the insulation thickness it is necessary to know or define the line and ambient temperatures and the relative humidity in order to determine the thermal conductivity and heat transfer coefficient of both the insulation and the object (pipe / duct etc.) to be insulated. These calculations can be made much more easily using the new ArmWin online and mobile tools provided by Armacell.
