Heat transfer modelling through building insulation that is based on new measurement strategy

Heat lost during the transfer in insulation characterizes the energy efficiency in buildings. Nowadays many discussions follow the aim whether polystyrene as porous insulating material meets the requirements that are put on building materials. One of the problems is not only heat lost due to conduction but also humidity level in the space between polystyrene panels and wall that can make an appropriate surrounding for attacks by microorganisms.
