Abstract
Using low thermal conductivity building insulation materials is an effective way to reduce heat transfer through walls in a building therefore save building energy cost. A device based on the transient hot strip (THS) method was developed to measure thermal conductivities of organic foam thermal insulation materials. The influences of sample dimension and heating power on the calculation accuracy of the thermal conductivity were analyzed by numerical simulations and compared with experimental results. Moreover, the selection method of the appropriate heating power was proposed. The measurement results show that the device has good accuracy for measuring organic foam insulation materials and outperforms transient hot wire (THW) method.
