Abstract
A moisture-variable protective layer is to be used in particular for protecting a thermal insulating layer in insulated building structures, such as roof and/or wall structures of a building. The protective layer has a water vapor diffusion-dependent air layer thickness Sd that is dependent on the ambient humidity. The protective layer at least partly consists of and/or comprises a material that has a water vapor diffusion equivalent air layer thickness Sd of greater than 10 m at a relative humidity of the atmosphere surrounding the protective layer in the range from 0% to 25% and has a water vapor diffusion equivalent air layer thickness Sd of less than 0.4 m at a relative humidity of the atmosphere surrounding the protective layer in the range from 90% to 100%.
