Papier Fassaden : Entwicklung konstruktiver Prinzipien für Fassaden aus Papierwerkstoffen mit Fokus auf Brandschutz, Wärmedämmung, Feuchteschutz und ökologische Eigenschaften

Climate change and the increasing scarcity of resources are decisive for the current developments in the construction industry towards sustainable and energy-efficient building. Paper materials have great potential for use in the construction industry in a closed-loop manner, since they are based on renewable raw materials and have optimized recycling processes so that they can be reused to a large extent as secondary raw materials. The first built projects and basic research demonstrate the suitability of paper materials for structural engineering applications. However, in order for architects, engineers and planners to be able to use paper in everyday construction projects, there is a lack of material data and experience. For this reason, this dissertation develops constructional principles for the use of paper materials in facades or exterior wall constructions, since these have the highest structural-physical requirements. The main question of the thesis is: Which constructionalprinciples are suitable to enable the increased use of paper materials as building materials by architects, engineers and planners? To answer this question, the topics of fire and moisture vulnerability of the material and the resulting building components, as well as thermal insulating and ecological properties, are primarily examined. The thesis is divided into eight chapters. In the first chapter, the introduction is given. Chapter two presents the basics of paper materials in construction such as the history and important material parameters. Chapter three deals with the technical material analyses. The fire protection, thermal insulation, moisture protection and ecological properties of the various paper materials are examined at the material level and placed in the context of conventional building materials. Paper materials with low raw density are highly flammable and may therefore only be used in combination with other materials, coatings or additives. However, they are well suited for thermal insulation functions and water ...
