Did You Know? That walk-in coolers, extruded polystyrene insulation (XPS) has advantages over polyurethane (PU) insulation


Consider these benefits:


  • Moisture resistance: Versus open-cell PU foam, XPS’s closed-cell structure makes it more resistant to moisture absorption, thus maintaining its insulating effectiveness.

  • R-value retention: while PU foam may lose its thermal resistance (R-value) due to aging and moisture absorption, XPS maintains R-value and insulating performance over its lifespan.

  • Strength and durability: XPS’s high compressive strength and deformation resistance make it superior for applications subject to mechanical loads or pressure. 

  • Fire resistance: With XPS’s higher fire resistance, it can meet even strict fire safety regulations.

  • Lower environmental impact: XPS can be manufactured with a lower environmental impact especially if recycled content or eco-friendly production methods are used as in green construction practices and certifications.
