Wall for separating the inside of a building from the outside

摘要

The wall serves for separating the inside of a building from the outside. According to a first aspect, the wall has a water vapor diffusion resistance of at most 20 meters, wherein the heat transfer coefficient amounts to at most 1.5 W/(m2·K), and the moisture storage capacity amounts to at least 2 kg/m2. According to a second aspect, the wall has a bearing layer (10) as well as an outer layer (9) and an inner layer (11), which include moisture-buffering materials.

1. A wall configured to separate the inside of a building from the outside, wherein the wall has a water vapor diffusion resistance, SD-value, of at most 20 meters, a heat transfer coefficient, U-value, of the wall is at most 1.5 W/(m2·K), and the moisture storage capacity, FK-value, of the wall, determined from a comparison of the state of the wall at 80% relative humidity and a temperature of 20 degrees Celsius with the dry state of the wall is at least 2.0 kg/m2,
wherein the wall is configured for climatic conditions in which a water vapor stream moves from the inside to the outside and from the outside to the inside, the wall including at least one moisture-buffering layer having absorption properties to absorb water vapor as the water vapor stream moves from the inside to the outside of the wall and from the outside to the inside of the wall.
