Extruded Polystyrene (XPS) is used in a wide range of construction applications thanks to its strength, moisture resistance, and insulation capabilities. In roofing systems, XPS boards provide durable thermal insulation that can withstand mechanical loads without compressing, making them suitable for inverted or green roofs.

In foundation and below-grade insulation, XPS serves as a barrier against cold and moisture, helping to reduce heat loss from building perimeters. Its closed-cell structure prevents water penetration, which is critical for protecting structural integrity.

Extruded Polystyrene is also a common choice in floor insulation, particularly in cold storage facilities where maintaining low temperatures is crucial. In civil engineering, XPS is used for road and railway embankment insulation to prevent frost heave.

Its easy handling, ability to be cut to size, and compatibility with various finishing materials make XPS a preferred choice for architects and contractors aiming for energy-efficient, long-lasting insulation systems.
