Title:
Abstract:	Torfmoos (Sphagnum) ist ein von alters her vielfach eingesetztes Dicht-, Füll-, und Dämmmaterial. Im Zuge der Bemühungen trockengelegte Moore wieder zu vernässen, wird die technische Nutzung von Torfmoosen (Sphagnum farming) erneut diskutiert. Im Rahmen der vorliegenden Untersuchung wurden die Wärmeleitfähigkeit und das hygroskopische Verhalten von unterschiedlich schweren Torfmoosmatten untersucht. Es zeigte sich, dass Torfmoos ein sehr vielversprechendes Fugendichtungsmaterial ist und die Dämmeigenschaften jenen von Polystyrol oder Mineralwolle ebenbürtig sind. Darüber hinaus wurden prototypische Baudetails zur Verwendung von Torfmoos als Dichtungs- und Dämmmaterial für die Bauanschlussfuge von Fenstern entwickelt. Torfmoos könnte hier eine Alternative zum weitverbreiteten PU-Schaum im ökologischen Bausektor sein. Peat moss (Sphagnum) - historic knowledge and new applications for a natural product. Peat moss (Sphagnum) was a commonly used sealant, fill and insulation material in the past. In the course of the efforts to rewet drained moors due to ecological reasons, the technical use of peat moss (Sphagnum farming) is in the focus of attention again. In the framework of this investigation, the thermal conductivity and the hygroscopic behavior of moss mats with varying density was investigated. The results showed that peat moss is a promising insulation material for building joints, because its thermal conductivity is comparable with the one of polystyrene or mineral wool. Moreover, prototypic building details were developed focusing on the application of peat moos for the insulation of the mounting gap of windows. In this respect, peat moss could be an ecological alternative to the widely used polyurethane foam.
