A transition test method is developed for determining the thermal properties of building materials using a guarded hot box apparatus. The model is presented and the results of the tests are analysed. The results are compared with the results from the standard guarded hot box test method (GHB). They are accurate and time saving. Compared with the conventional test method, this new approach can reduce the test time from 24 hours to within only 2 hours. For determining the temperature-dependent thermal conductance (equivalent value) of a sample of transparent insulation materials, several days can be saved. The method can be also used to measure the insulation properties of materials with low thermal conductance, to which the conventional method cannot be applied with a GHB.
