Moisture and Durability Performance of Low-Sloped Roof Structures with Varying Surface Types

Source

This paper will present an analysis regarding the hygrothermal performance and durability of non-ventilated lightweight flat roofs with different roofing membranes in the Central European climate. The main focus is assessing the drying potential of selected roof variants in order to predict the potential risks for mold and especially wood decay fungi growth inside the roof construction. Several numerical simulations were carried out to investigate the influence of different roofing membranes (and especially cool roofing products) on the overall hygrothermal conditions inside the roof construction. In addition, roof assemblies with cool roofing membranes were investigated at the Austrian Building Science Research & Test Unit (BSRTU) outdoor test facility (www.building-science.at) of the Carinthia University of Applied Sciences (CUAS). In situ measurement results, taken at this experimental facility, will be discussed.
