diffusionsåbne
Diffusionsåbne refers to a property of building materials that allows water vapor to pass through them. This characteristic is crucial in construction for managing moisture within a building envelope. Materials that are diffusionsåbne permit water vapor to escape from the interior of a building to the exterior, preventing condensation from forming within the wall or roof structure. This is achieved because the material has a high water vapor diffusion resistance factor (Sd-value). A low Sd-value indicates that the material is more permeable to water vapor.
The concept of diffusion openness is particularly important in strategies for creating energy-efficient and durable buildings,
