During the revitalization of the panel house of the VVU ETA system, the opening elements, roof insulation and perimeter vertical constructions were replaced. In the final stage, the lifts were completely replaced. On loggias that have already been glazed to minimize the financial impact on their replacement, the main handrail of the new loggia rail has been reduced and the standard height has been reached in front of the handrail anchored from the railing front. The insulation system was used by Baumit.
