Abstract

An insulated building structure, in particular an insulated roof structure or a wall structure of a building, comprises at least one thermal insulation layer. At least one moisture-variable protective layer for the thermal insulation layer is provided on an outer side of the thermal insulation layer and on an inner side of the thermal insulation layer facing a building interior of the building. The protective layers each have a water vapor diffusion equivalent air layer thickness Sd. The water vapor diffusion equivalent air layer thicknesses Sd of the two protective layers deviate from each other by less than 20%, preferably less than 10%, in the range of a relative humidity from 0% to 25% and/or in the range of a relative humidity from 80% to 100%.
