The balconies of the Athena Building are designed as a combination of curved and straight units, some cantileverd and others inset. With the need for energy conservation, reduction in CO2 emissions and for preventing thermal bridges the Isokorb® type K has been incorporated into the development, The type K Isokorb® has outstanding thermal insulation properties and dramatically reduces thermal energy loss in connective areas by guaranteeing the homogeneity of the thermal envelope between cantilever structures and the internal floor.
