Interior and exterior extruded panel, also known as extruded insulation board, is made from polystyrene through an extrusion process. It features excellent thermal insulation, soundproofing, fire resistance, water resistance, and high compressive strength. Lightweight and easy to install, it is widely used for both thermal insulation and decoration on interior and exterior walls, as well as for roof insulation, cold storage, and soundproofing applications.
