The energy renovation of existing buildings represents a key component of the “Energiewende” (energy revolution). The building envelope and the system technology used within the building itself form a single unit. Prior to a building renovation project, these two aspects should thus in principle be analysed together. Within this publication, however, only the building shell is to be addressed, with a focus being placed on thermal insulation. The authors provide their views on the most frequent objections, prejudices and misunderstandings in connection with structural thermal insulation and the use of insulating materials.
