Polyurethane filled sandwich panel is a building material with polyurethane filling material between two metals. These panels are used in roofs, facades, interior partitions or cold storages of buildings. In addition to providing high thermal insulation, polyurethane-filled sandwich panels offer advantages such as fire resistance, lightness, high carrying capacity and easy installation features. In addition, the use of sandwich panels as modern, light and durable construction elements offers a fast and efficient solution in construction projects. These panels also provide protection of structures against external factors and create an aesthetic outer shell. Polyurethane filled sandwich panels are generally preferred in areas such as industrial facilities, warehouses, logistics centers, production facilities and cold storages.
