The aim of aerodurit is to work with nature instead of against it and use physical laws. aerodurit building materials allow your home to breathe; they are open to diffusion and breathable like functional sportswear. No athlete would use clothing that is airtight like a plastic bag and does not allow moisture to pass through. However, hydrophobic building materials do exactly that: rooms are “packed” practically airtight. Moisture created, for example, during cooking or in the bathroom, can therefore no longer escape from the interior. The result is all too often the formation of mould, which is a major health hazard.
