Extruded Polystyrene insulation is one of the two main insulation materials used in the manufacturing process for walk-in coolers and freezers. Extruded polystyrene insulation is a closed-cell insulation structure with resistance to moisture absorption. These characteristics, along with it’s strength are what make Extruded Polystyrene the optimal choice for the cold storage industry.
Maintains a High R-Value
Extruded Polystyrene’s closed-cell structure and lack of voids results in a higher, longer lasting R-value. Extruded Polystyrene holds its R-value longer than other insulations. While other insulations only retain 25% of their R-value within 5 years, Extruded Polystyrene retains 75% of it’s R-value over 5 years.
