Thermischfeuchte
Thermischfeuchte refers to the moisture content within a building material that is influenced by thermal gradients. When a temperature difference exists across a material, it can cause moisture to migrate from warmer regions to colder regions. This phenomenon is particularly relevant in building physics and the study of hygrothermal performance of building envelopes. The movement of moisture, whether in vapor or liquid form, is driven by the partial vapor pressure differences that arise due to temperature variations. Warmer air can hold more moisture than colder air, leading to condensation when moist air comes into contact with a colder surface. This condensation can occur within the material itself or on its surfaces, potentially leading to detrimental effects such as mold growth, material degradation, and reduced insulation performance. Understanding thermischfeuchte is crucial for designing buildings that are durable, healthy, and energy-efficient. Building codes and standards often address thermischfeuchte through requirements for vapor barriers, insulation, and ventilation to control moisture accumulation. Analysis of thermischfeuchte involves considering factors like material properties (permeability, sorptivity), ambient conditions (temperature, humidity), and the thermal bridge effects within a structure.
