Extruded Polystyrene (XPS) is a rigid foam insulation material known for its closed-cell structure, high compressive strength, and excellent thermal performance. It is widely used in construction due to its durability, moisture resistance, and ability to maintain insulating properties over time.
Extruded Polystyrene is manufactured by melting polystyrene crystals and extruding the material through a die to create continuous boards. This extrusion process creates a closed-cell foam with consistent density and minimal voids, giving it superior insulation performance compared to expanded polystyrene (EPS).
One of XPS’s standout features is its low water absorption, making it ideal for below-grade applications, such as foundation walls, basement insulation, and under concrete slabs. It also has excellent resistance to freeze-thaw cycles, making it suitable for harsh climates.
XPS insulation boards are available in a range of thicknesses and compressive strengths, allowing for versatility in both residential and commercial projects. Their ability to deliver long-term energy efficiency makes them a key material in modern building design.
