Austria: Austrotherm says that its Resolution Facade foam insulation product is being used for exterior renovations in Vienna’s many pre-1919 apartment blocks. These kinds of jobs require thin insulation to maintain a building’s profile.
Sales director Robert Novak said, “An apartment building built before 1919 has a heating requirement of 120 - 250kWh/m2. They are therefore five times worse than newly-built residential complexes, which have had to meet the lowest energy house standard across Europe since 1 January 2021.” He concluded, “There is still a lot of renovation potential in this building category.”
Buildings of this period currently house 500,000 people in Vienna and number 30,000, 20% of the total number of residential buildings. 20,000 are in the Wilhelmian architectural style, known for its facades.
