Hygrothermische und Biohygrothermische Simulationen an Bauteilen mit einer Dämmung aus Strohballen

Marc Klatecki, Frank Otto

Abstract: Since the 19th Century houses are built from straw bales. Since straw is biological usable a high risk of material moisture elist. To derive more information about the usability of components with straw bales, extensive hygrothermal and biohygrothermal simulations are carried out with the simulationprograms WUFI-Pro 4.1 (Künzel,1994) and WUFI-Bio 2.0 (Sedlbauer, 2001). The investigations showes that wall- and roofstructures without adequate weather protection have a strong mold growth within the straw bale. With an effective driving rain protection, partly combined with an additional insulation on the outside, sufficient moisture protection could be established for some components.
