Claim:
1. An insulated building structure, having at least one thermal insulation layer, wherein at least one moisture-variable protective layer for the thermal insulation layer is provided on an outer side of the thermal insulation layer and also on an inner side of the thermal insulation layer facing a building interior of a building, wherein the moisture-variable protective layers each have a water vapor diffusion equivalent air layer thickness S d that depends on the ambient moisture, wherein the water vapor diffusion equivalent air layer thicknesses S d of both moisture-variable protective layers, in the range of a relative humidity between 0% and 25%, or in the range of a relative humidity between 80% and 100%, differ from each other by less than 20%, wherein an increase in the relative humidity of air surrounding each moisture-variable protective layer leads to a lowering of the S d value, and a decrease in the relative humidity of air surrounding each moisture-variable protective layer leads to an increase in the S d value.
