Production and Physical–Mechanical Characterization of Peat Moss (Sphagnum) Insulation Panels

Peat moss (sphagnum) is a commonly used sealant, fill, and insulation material in the past. During the efforts to rewet drained moors due to ecological considerations, the technical use of peat moss (sphagnum farming) again became the focus of attention. In the framework of this investigation, insul...
