The fast and precise transient hot‐strip (THS) method is well suited for thermal conductivity measurements on solid materials. The THS method may, however, give large experimental errors when applied to thermally insulating materials of low heat capacity per unit volume. Models to deal with those potential error sources and some indications about the precautions to be taken in order to minimize them are described in the present work. Measurements of thermal conductivity of a styrofoam insulating material (thermal conductivity 0.036 W m −1 K −1 , density 25.4 kg m −3 ) was performed to verify the models. The result obtained is in good agreement with the standard hot plate method, indicating that the THS method is also well suited for thermal conductivity measurements of thermal insulators.
