The article presents the results of tests of the thermal operation of a transparent barrier, which is equipped with an external thermal insulation roller blind. The tests were carried out under real climatic conditions. The barrier in question was mounted on the south façade in two external test chambers. The aim of the research was to determine whether and to what extent the external thermal insulation roller blind influences the flow of heat through the transparent barrier. The second goal was to propose a way of programming the position of the blind so that it would be beneficial in both limiting of overheating in the adjacent room during the high summer sunshine and minimizing the need to reheat the room in the case of high clouds and low temperatures in the outside air. During the tests, the following values were measured: the intensity of solar radiation, temperature (outside air, indoor air and the internal surface of the barrier), as well as the heat flux density on the internal surface of the barrier. The test results indicate that the use of an external thermal insulation roller blind has a significant impact on the thermal operation of the transparent barrier and thermal comfort in the room adjacent to the barrier. The method of programming of the position of the blind should take into account both the temperature of the outside air and the value of the intensity of solar radiation, as well as the temperature of the air in the room adjacent to the barrier, and the direction and values of the heat flux passing through this barrier.
