The project

In the case of diffusion-inhibiting interior insulation systems, the penetration of water vapour from the inside into the construction is prevented or inhibited by the use of a vapour barrier. Drying out from the inside is not possible with these systems (or very slow). The limits of this approach are obvious: on the one hand, the aim is to achieve the highest possible drying potential, on the other hand, the presence of a vapour barrier is essential under certain boundary conditions (e.g. high indoor air humidity). Moisture-adaptive vapour retarders offer the advantage of inhibiting vapour diffusion from the indoor air without reducing the drying potential of the wall. The aim of this master's thesis is to develop optimal moisture-adaptive vapour retarders for different boundary conditions, insulation materials and wall stratigraphy.
