Currently, prefabricated wall systems are gaining more and more relevance. The increasing demands on thermal and sound insulation require multi-layer construction systems, which have a high mass for sound absorption and at the same time provide thermal insulation to ensure efficient protection against high and low temperatures. Added to this is the often-prevailing lack of qualified personnel on the construction site. The exterior wall system presented in this article by the company ‘if innovative fertigteile gmbh’ combines the advantages of the core-insulated element wall and the EIFS (exterior insulation and finish system) while avoiding the disadvantages associated with either technology. Thanks to an externally applied in-situ plaster, the exterior wall system does not require a facing shell made of reinforced concrete, analogous to a EIF system with acceptance of the reduction of the degree of prefabrication. The advantages of reduced wall thickness and semi-precast construction are combined.
