Extruded polystyrene Fibrostir XPS is a thermally insulating material with closed-cell structure, manufactured from thermoplastic polystyrene in the form of sheets. Fibrostir XPS sheets are characterized by high and long-lasting thermal insulation properties, a low thermal conductivity coefficient (λ), zero moisture absorption, high compressive strength, and non-flammability behavior.
They maintain consistent density, dimensional stability, and excellent compatibility with construction materials (cement, plaster, mortar, anhydrite, sand), ensuring strong adhesion to concrete and paint.
