Characteristics of the Extruded Polystyrene XPS
Extruded polystyrene (XPS), or its common name “fibran”, is an insulation board made by extruding pre-foamed polystyrene so that it contains multiple air bubbles. The production technology gives a closed lattice structure with smaller particles (chambers smaller than 1 mm), hence the better mechanical properties of insulation boards compared to EPS. This achieves absolute impermeability […]
