OPERATION In the renovation project of the Grinton I Will - Yonkers Public Library, Aliva designed and supplied multi-colored extruded aluminum sunscreen panels, ensuring greater light entry and protection from ultraviolet rays. On the facade, the terracotta slabs mounted on the Aliva substructure, will take the place of the concrete panels. All the facade implementations had a strong impact on the sustainability of the building, increasing its energy efficiency.
