dampsperreluftespredning
Dampsperreluftespredning refers to the phenomenon of air movement through a building's envelope that carries moisture. This process is particularly relevant in colder climates where there is a significant temperature difference between the interior and exterior of a building. Warm, moist indoor air can migrate through cracks, gaps, and material permeability in the building's structure. As this air moves towards colder exterior surfaces, its temperature decreases, and its ability to hold moisture is reduced. This can lead to the moisture condensing within the building's wall or roof assemblies.
The consequences of uncontrolled dampsperreluftespredning can include reduced thermal performance of insulation, as moist insulation loses
To mitigate dampsperreluftespredning, building codes and best practices emphasize the importance of an effective air barrier
