👉 Semipervious refers to a type of material used in the construction or renovation of buildings. It is typically composed of two layers, with one layer being covered by a reflective surface and the other being undisturbed. This allows for a certain amount of natural light to pass through but also prevents direct sunlight from entering the building. Semipervious materials are often used in commercial settings such as offices or retail spaces to reduce the need for windows and improve air circulation, making them more energy-efficient
