👉 Nonfenestrated is a concept in architecture, which refers to the absence of windows or other openings on the exterior walls of a building. In other words, it means that the interior space inside the building is completely enclosed and does not allow for any openings to be seen from outside. In general, nonfenestration is used in buildings with high levels of humidity or in areas where natural ventilation is limited. It helps prevent drafts and improves thermal insulation, making the building more energy-efficient and comfortable
