Extruded Polystyrene (XPS)
Extruded Polystyrene, abbreviated as XPS, is a rigid, high-performance insulation material with a closed-cell structure. XPS is produced by an extrusion process, where polystyrene polymer is heated, melted, and then continuously extruded into sheets. As a result, XPS forms a strong, homogeneous material with a tight cell structure, offering excellent insulation properties.
