“30 tage wetter side” is a German phrase meaning “30 day weather side.” It refers to the side of a building or other structure that faces the prevailing wind and receives the most rainfall. This side of the building is often more exposed to the elements and can experience more wear and tear than the other sides.
The 30 tage wetter side of a building is an important consideration for architects and builders. They need to take into account the potential for increased moisture damage and wind damage when designing and constructing the building. This side of the building may also require more frequent maintenance and repairs.
