The Aularios Building of the Universidad de O'Higgins, designed by architect Cristian Pino in Rancagua, is a model of efficiency in modular design. This project, which includes 25 auditorium-type classrooms, library and study hall, is distinguished by its rational design and limited use of materials, optimizing time and tight budgets. In the interiors, the predominance of exposed concrete is balanced by Masisa's Carvalo acoustic ceilings and paneling, which add warmth and functionality. These coatings not only add a welcoming aesthetic, but also optimize the acoustic conditioning of the rooms, creating an ideal environment for learning. Masisa's products allow for a balanced environment, where contemporary design and functionality combine to maximize user comfort.
