Measurement system for testing reliability of building insulation

Thermal properties of building insulation are changed by the action of various external and internal influences. This causes the need for insulation material testing after a period of ten or fifteen years without its disturbing. The new measurement technology can monitor the temperature and humidity in the cavity between the building wall and insulation material. This procedure allows also detecting condensation process and this way to prevent subsequent destructive problems as well as creating an enabling environment for the spread of microorganisms, which are counted as serious risk processes in building insulation. The problem is the main topic of the research project carried out at the University of Prešov in Prešov and Vienna University of Technology entitled “Detection and Management of Risk Processes in Building Insulation” and numbered SRDA SK-AT-0008-10. It was uncovered during the project work that one or two measurements cannot describe the real situation in its entirety. The set of measurement series are required. Those can lead to description reliability of building insulation using the statistical methods to model its properties.
