Interior and exterior extruded panel, also known as extruded insulation board, is a plate-like material made of polystyrene through an extrusion process. It features light weight, good thermal insulation, sound insulation, fire resistance, water resistance, and high compressive strength. Widely used in building interior and exterior wall insulation and decoration, this material effectively reduces energy consumption, improves indoor comfort, and enhances building safety. With a uniform and dense structure, it offers excellent dimensional stability and long service life. Common applications include external wall insulation, internal wall insulation, roof insulation, cold storage, and soundproofing systems.
